📋 Summary

This paper introduces MotivGraph-SoIQ, a novel framework designed to enhance the ideation capabilities of Large Language Models (LLMs) in academic research. The core contribution lies in addressing two key challenges that hinder the effectiveness of LLMs in this domain: the lack of motivational grounding and the limited capacity for self-improvement. To tackle these issues, the authors propose an integrated approach that combines a Motivational Knowledge Graph (MotivGraph) with a Q-Driven Socratic Ideator. The MotivGraph is constructed using a method called SciMotivMiner, which extracts structured knowledge about research problems, challenges, and solutions from scientific papers, representing them as triplets. This graph serves as a foundational knowledge base, providing the LLM with a deeper understanding of the research landscape. The Q-Driven Socratic Ideator, on the other hand, employs a dual-agent system consisting of a researcher agent and a mentor agent. The researcher agent generates initial ideas, which are then critically evaluated by the mentor agent through a series of Socratic questions. This iterative dialogue process aims to refine the ideas, mitigate confirmation bias, and enhance their overall quality. The paper's methodological approach involves several key components. First, the SciMotivMiner extracts (problem, challenge, method) triplets from scientific papers, which are then used to construct the MotivGraph. The graph is represented as a network of nodes (problems, challenges, and solutions) and edges (parent-of, problem-challenge, and challenge-solution). The researcher agent utilizes API tools to interact with the MotivGraph, performing fuzzy searches and retrieving node relations to gain a comprehensive understanding of the research domain. The Socratic Ideator then engages in a dialogue, with the mentor agent posing questions related to innovation, feasibility, and rationality. The paper's empirical evaluation is based on a dataset of ICLR 2025 paper topics. The authors compare their approach against several baselines, including a model-based evaluation using Fast-Reviewer and a Swiss Tournament evaluation. The results indicate that MotivGraph-SoIQ outperforms the baselines in terms of novelty, experimental feasibility, motivational rationality, and diversity. The authors also conduct a manual evaluation of a subset of the generated ideas to further validate the findings. The overall significance of this work lies in its potential to enhance the creative capabilities of LLMs in academic research. By integrating structured knowledge with a critical dialogue process, MotivGraph-SoIQ offers a promising approach to generating more grounded, novel, and high-quality research ideas. This could have significant implications for researchers seeking to explore new avenues of inquiry and accelerate the pace of scientific discovery. However, the paper's current focus on the AI domain and the limitations of the evaluation methodology suggest that further research is needed to fully realize the framework's potential across diverse scientific disciplines.

✅ Strengths

The paper presents a novel and well-structured approach to enhancing LLM-based academic ideation. I appreciate the authors' efforts in addressing the critical challenges of motivational grounding and self-improvement in LLMs. The integration of a motivational knowledge graph with a Socratic dialogue framework is a particularly innovative aspect of this work. This combination offers a promising solution to the limitations of LLMs in generating grounded and high-quality research ideas. The authors provide a thorough explanation of the framework's components, including the structure of the MotivGraph, the design of the Socratic dialogue loop, and the methods for knowledge extraction and idea evaluation. The experimental setup is well-documented, and the results are presented clearly, making it easy to follow the evaluation process. The use of both automated and manual evaluations, although limited in detail, demonstrates a commitment to validating the proposed method. The paper addresses important limitations of LLMs in academic ideation, such as the lack of grounding and confirmation bias, and proposes a comprehensive solution that combines structured knowledge with critical self-reflection. The authors' efforts to mitigate confirmation bias through the Socratic dialogue are particularly noteworthy. The framework's ability to generate ideas that are evaluated as more novel, feasible, and motivated compared to baselines suggests that it has the potential to significantly enhance the creative capabilities of LLMs in academic research. The paper's focus on enhancing the quality of research ideas is highly relevant to the current landscape of scientific discovery, where the ability to generate novel and impactful ideas is increasingly crucial.

❌ Weaknesses

After a thorough analysis of the paper, I have identified several weaknesses that warrant further discussion. Firstly, the paper lacks a clear and detailed explanation of how the MotivGraph is constructed and how it integrates with the Socratic Ideator. While the authors introduce SciMotivMiner for extracting (problem, challenge, method) triplets, they do not specify the natural language processing techniques used. For instance, the paper does not detail the parsing techniques, named entity recognition models, or relation extraction methods employed. This lack of detail makes it difficult to understand the exact process of knowledge extraction and raises concerns about the reproducibility of the MotivGraph construction. Furthermore, the paper provides only a high-level description of the graph structure, omitting crucial implementation details. The representation of nodes and edges, as well as the mechanisms by which LLM agents query and traverse the graph, are not adequately explained. This lack of transparency hinders a full understanding of how the knowledge graph influences the dialogue flow and idea generation process. The integration between the knowledge graph and the Socratic dialogue is also not well-defined. Although the paper mentions API tools for the researcher agent to interact with the MotivGraph, the underlying mechanisms of how these tools facilitate the flow of information from the graph to the LLM agent remain unclear. This makes it challenging to assess the effectiveness of the integration and its impact on the quality of generated ideas. I am confident in this assessment with a high level of certainty, as these details are crucial for understanding the core methodology and are consistently absent throughout the relevant sections of the paper. Secondly, the evaluation of the proposed method relies heavily on automated metrics and LLM-based evaluations. While the authors acknowledge the time-consuming nature of manual evaluation and cite the efficacy of LLMs in judging text quality, the paper does not provide sufficient details about the human evaluation process. The number of evaluators, their expertise, and the specific criteria used for assessing the generated ideas are not clearly stated. This lack of transparency makes it difficult to assess the validity and reliability of the evaluation results. Moreover, the paper lacks a rigorous comparison with human-generated ideas. Although the "RealPaper" baseline provides some context, a more in-depth qualitative comparison would be beneficial to understand the practical value of the proposed method. The paper also does not include a detailed analysis of the limitations of the automatic metrics and LLM-based evaluations. This omission is significant, as it prevents a comprehensive understanding of how these limitations might affect the results. I am highly confident in this assessment, as the reliance on automated metrics without a thorough discussion of their limitations is a recurring theme throughout the evaluation section. Thirdly, the paper does not provide sufficient details about the implementation of the Q-Driven Socratic Ideator. The specific prompting strategies used to guide the LLM agents during the Socratic dialogue are not detailed. The paper mentions the types of questions posed by the mentor agent (Innovation, Feasibility, Rationality) but does not provide examples of the actual prompts used. This lack of detail makes it difficult to understand how the dialogue is initiated and maintained. Additionally, the paper does not consistently clarify the number of dialogue rounds used in the experiments. While it mentions that the number of deliberation rounds can be preset, the specific number used is not consistently stated, making it challenging to assess the efficiency of the dialogue process. The criteria for terminating the dialogue are also vaguely defined. The paper states that the mentor may end the dialogue early if the idea is clearly strong or unviable, but the specific criteria for this decision are not explicitly defined. Furthermore, the paper does not provide a clear explanation of how the quality of the generated ideas is evaluated within the Socratic dialogue process. While the evaluation criteria (Novelty, Experiment, Motivation) are mentioned in the context of Fast-Reviewer, it is unclear how these criteria are applied by the mentor agent during the dialogue to guide the refinement of ideas. I am highly confident in this assessment, as the lack of detail regarding the prompting strategies, dialogue rounds, termination criteria, and evaluation within the dialogue is consistently evident throughout the method and experiment sections. Finally, the paper lacks a detailed discussion of the computational costs associated with constructing and maintaining the MotivGraph and the overhead introduced by the Socratic dialogue loop. This information is crucial for assessing the practicality and scalability of the proposed framework. The absence of any discussion or data related to computational resources makes it difficult to evaluate the feasibility of implementing the framework in real-world scenarios. I am highly confident in this assessment, as the lack of any mention of computational costs is a significant omission for a framework involving complex knowledge graph construction and iterative dialogue processes. The paper also does not adequately address the potential limitations of the Socratic dialogue approach in mitigating confirmation bias. While the authors propose the Socratic dialogue as a means to mitigate this bias, they do not provide a detailed analysis of its effectiveness or potential shortcomings. The possibility of the mentor agent being susceptible to biases is also not discussed, which is a significant concern given the reliance on the mentor's critical evaluation for idea refinement. I am highly confident in this assessment, as the lack of analysis on the mentor's effectiveness and the absence of any discussion on potential biases of the mentor agent are significant omissions in a paper that aims to mitigate confirmation bias.

💡 Suggestions

To address the identified weaknesses, I recommend the following improvements. Firstly, the authors should provide a more detailed explanation of the SciMotivMiner method, including the specific natural language processing techniques used for extracting (problem, challenge, method) triplets. This should include details on the parsing techniques, named entity recognition models, and relation extraction methods employed. For example, the authors could specify the libraries or tools used for each step and provide examples of how these techniques are applied to extract triplets from a sample text. Furthermore, the paper should clarify how the graph structure is represented, including the node and edge types, and how the LLM agents query and traverse this graph during the ideation process. Providing concrete examples of how the knowledge graph is used to generate a specific idea would greatly enhance the reader's understanding. This would help clarify the integration between the knowledge graph and the Socratic dialogue, and how the graph influences the dialogue flow and idea generation. The authors should also include a discussion of the limitations of the knowledge graph, such as potential biases in the extracted triplets and the coverage of the graph. To improve the evaluation methodology, the authors should include a more detailed description of the human evaluation process. This should include the number of evaluators, their expertise in the relevant domains, and the specific criteria used for assessing the generated ideas. Providing examples of both successful and unsuccessful idea generations would also be beneficial. The authors should also include a more detailed analysis of the limitations of the automatic metrics and LLM-based evaluations, and how these limitations might affect the results. This analysis should include a discussion of the potential biases in the LLM-based evaluations and how these biases might affect the conclusions of the paper. The paper should also explore alternative evaluation metrics that could provide a more comprehensive assessment of the quality and novelty of the generated ideas. To provide more details about the implementation of the Q-Driven Socratic Ideator, the authors should provide a more detailed description of the prompting strategies used to guide the LLM agents during the Socratic dialogue. This should include examples of the prompts used and a discussion of how these prompts were designed. The paper should also clarify the number of dialogue rounds and how the dialogue is terminated. Furthermore, the paper should provide a clear explanation of how the quality of the generated ideas is evaluated, including the specific criteria used and how these criteria are applied in practice. The paper should also include an analysis of the sensitivity of the results to different prompting strategies and dialogue parameters. This analysis should include a discussion of how the choice of prompting strategies and dialogue parameters might affect the quality and novelty of the generated ideas. The authors should also include a more detailed analysis of the computational resources required for constructing and maintaining the MotivGraph, including the time and memory requirements for processing scientific papers and updating the graph structure. Furthermore, the authors should quantify the computational overhead introduced by the Socratic dialogue loop, including the number of LLM calls and the time required for each dialogue iteration. This analysis should also consider the scalability of the framework to larger datasets and more complex knowledge graphs. Providing concrete benchmarks and resource utilization metrics would greatly enhance the practical value of the work and allow for a more informed assessment of its feasibility. The paper should also address the potential limitations of the Socratic dialogue approach in mitigating confirmation bias. The authors should provide a more detailed analysis of the mentor agent's effectiveness in challenging the researcher agent's assumptions and ideas, and discuss how the framework handles situations where the mentor agent might also be susceptible to biases. It would be beneficial to include a case study or example of a Socratic dialogue session, highlighting the specific questions and challenges posed by the mentor agent, and how these challenges lead to the refinement of the generated ideas. Furthermore, the authors should discuss the potential for incorporating diverse perspectives into the mentor agent to further mitigate bias.

❓ Questions

Based on my analysis, I have several key questions that I believe need to be addressed to fully understand and evaluate the proposed framework. Firstly, can the authors provide more details on the specific natural language processing techniques used in SciMotivMiner for extracting (problem, challenge, method) triplets? What parsing techniques, named entity recognition models, and relation extraction methods were employed? How were these techniques chosen, and what are their limitations in the context of scientific text? Secondly, how exactly is the MotivGraph structured? What are the specific attributes of the nodes and edges, and how are they represented in the system? How do the LLM agents query and traverse this graph during the ideation process? Can the authors provide a concrete example of how the knowledge graph is used to generate a specific idea? Thirdly, what are the specific prompting strategies used to guide the LLM agents during the Socratic dialogue? Can the authors provide examples of the prompts used for both the researcher and mentor agents? How were these prompts designed, and what is the rationale behind their structure? Fourthly, what is the typical number of dialogue rounds in the Socratic Ideator, and what criteria are used to terminate the dialogue? How does the number of rounds affect the quality of the generated ideas, and what is the trade-off between the number of rounds and computational cost? Fifthly, can the authors provide more details on the human evaluation process? How many evaluators were involved, what was their expertise, and what specific criteria were used to assess the generated ideas? How was inter-rater reliability ensured? Sixthly, what are the computational costs associated with constructing and maintaining the MotivGraph, and what is the overhead introduced by the Socratic dialogue loop? How does the framework scale with larger datasets and more complex knowledge graphs? Finally, how does the framework handle situations where the MotivGraph lacks sufficient information to ground the idea generation process? How does the framework address the potential for the mentor agent to also be susceptible to confirmation bias? What mechanisms are in place to ensure that the generated ideas are not only novel but also ethically sound and do not perpetuate existing biases in the training data?

📋 Summary

The paper proposes MotivGraph-SoIQ, a framework to improve LLM-based academic ideation by combining (i) a Motivational Knowledge Graph (MotivGraph) built from literature using SciMotivMiner, which extracts (problem, challenge, solution) triples and induces hierarchical parent nodes, and (ii) a dual-agent Q-Driven Socratic Ideator (mentor/researcher) that iteratively refines ideas via questioning along three axes (innovation, feasibility, rationality). The Exploration Phase provides tools for fuzzy graph search, relation retrieval, Semantic Scholar queries, and a "Get Random Nodes" mechanism to spur novelty; the Deliberation Phase engages multi-round Socratic critique to mitigate confirmation bias. Experiments on a 100-topic ICLR 2025 dataset compare against AI-Researcher, CycleResearcher, AI-Scientist-v2, SciPIP, and ResearchAgent using LLM judges (Fast-Reviewer), ELO-style Swiss tournaments, and limited human evaluation. The method shows gains in novelty, experiment feasibility, and motivation scores, and ablations attribute improvements to both the graph and the mentor loop.

✅ Strengths

  • Clear problem framing: addresses two concrete bottlenecks in LLM ideation—grounding (via literature-derived motivational structure) and confirmation bias (via Socratic dual-agent critique).
  • Methodological novelty tailored to academic ideation: a structured motivational KG with (problem, challenge, solution) schema and LLM-driven hierarchical parent node induction (Section 2.1.1–2.1.2); and a dual-agent Socratic loop with targeted axes (innovation/feasibility/rationality) (Section 2.2).
  • Design features that plausibly encourage novelty and grounding: the "Get Random Nodes" tool to inject cross-linking ideas (Section 2.2.1) and graph-based relation retrieval for concrete motivational triplets.
  • Systematic ablations demonstrating the contributions of key components (Table 3; W/O Mentor, W/O Graph, SciPIP-graph replacement, W/O Semantic Scholar), with qualitative hypotheses (Section 4.2).
  • Comparisons against relevant baselines (Section 3.1) and multiple evaluation regimes (LLM-as-judge, Swiss tournament ELO, and a small human study) showing consistent gains (Table 1, Table 2).

❌ Weaknesses

  • Evaluation circularity and limited human validation: heavy reliance on LLM-based evaluators (Fast-Reviewer and DeepSeek-V3 Swiss tournaments) risks validating self-referential patterns. Human evaluation is limited (scope and detail not fully specified), and no statistical significance tests or variance measures are reported (Sections 3.3–3.4; Tables 1–2).
  • Insufficient detail on the construction quality of the MotivGraph: missing statistics on graph size, coverage, and error rates; no reported precision/recall or human validation of SciMotivMiner’s (P,C,S) extractions or the LLM-driven hierarchical parent induction decisions (Section 2.1.2).
  • Reproducibility gaps: absent reporting of seeds, prompts, sampling parameters, hardware, training/tuning budgets, and API call limits; unclear details of the fuzzy search/retrieval stack (indexing, embeddings, top-k, re-ranking) and exact deliberation settings (round counts, stop criteria) (Sections 2.2, 3.4).
  • Potential selection bias: the mentor agent issues final ACCEPT/REJECT (Section 2.2.2). It is unclear whether rejected ideas are removed before evaluation and whether this differs across baselines, which could inflate scores.
  • Scope limited largely to AI topics with one dataset of ICLR 2025 paper topics (Section 3, Limitations), limiting evidence of generalization to other scientific domains where the motivational landscape and literature density differ.
  • Lack of qualitative case studies and failure analyses: few concrete examples of how the Socratic questioning corrected flawed assumptions or mitigated confirmation bias; limited analysis of negative outcomes or hallucinations (Sections 4.1–4.2).
  • Ambiguity in baseline parity and judging protocol: e.g., whether the same judge model family is used across methods (which can bias outcomes), inter-annotator agreement in human studies, and whether prompt lengths and resource budgets are matched (Table 1 shows large variance in output lengths).

❓ Questions

  • MotivGraph construction: What is the graph’s scale (number of P/C/S nodes and edges), domain coverage, and distribution across subfields? What embedding model, k, thresholds, and LLM prompts were used in hierarchical parent induction (Section 2.1.1–2.1.2)?
  • Extraction quality: Do you have precision/recall or human audit results for SciMotivMiner’s (Problem, Challenge, Solution) triplets and for parent-node additions? How often are merges incorrect, and how are conflicts resolved?
  • Selection bias: In the Deliberation Phase (Section 2.2.2), when the mentor issues REJECT, are these ideas discarded prior to evaluation? If so, is this filtering applied equally to baselines? Please quantify acceptance rates per topic and per method.
  • LLM-as-judge validity: How did you mitigate circularity in LLM judging (e.g., model-family separation between generators and judges, randomized and blinded presentation, calibration with human ratings)? Do you report correlations with human ELO and inter-rater agreement?
  • Statistical rigor: Can you report confidence intervals or standard deviations across topics and run seeds, and include statistical significance testing for the main claims (e.g., 10.2% novelty gain)?
  • Human study design: How many topics and raters, what were the instructions, and what was the inter-annotator agreement? Were raters blinded to method identity and to whether text came from a real paper vs. an LLM?
  • Baselines and resource parity: Were decoding parameters, prompt lengths, retrieval budgets, and API access normalized across methods? Table 1 shows very different output lengths—could verbosity be confounding LLM scores?
  • Ablations: In Table 3, could you add an ablation isolating the "Get Random Nodes" novelty tool? Also, analyze the mentor’s questioning axes separately (innovation vs feasibility vs rationality) to measure their distinct impact.
  • Generalization: Have you tested on non-AI domains (e.g., biomedicine, physics)? If not, can you provide preliminary results or error analyses indicating how the framework would adapt?
  • Release plan: Will you release SciMotivMiner code, the MotivGraph, prompts, and evaluation scripts to facilitate reproducibility?

⚠️ Limitations

  • Domain scope: The constructed MotivGraph is mostly AI-centric (Section 6), limiting cross-disciplinary validation.
  • Evaluation circularity and limited human validation: Strong reliance on LLM judges may reward model-preferred stylistic features; more robust human studies are needed.
  • Reproducibility and transparency: Missing seeds, prompts, compute/hardware specs, and tuning details; absent reporting of selection filters (mentor Accept/Reject) and their impact on evaluation.
  • Potential extraction and hierarchy errors: SciMotivMiner and parent-node induction may propagate inaccuracies; no error rates or audits are provided.
  • Bias and safety: The KG and literature retrieval may reflect field-specific biases; novelty injection via random nodes can induce spurious analogies. Although an Ethics Statement is included (Section 7), additional safeguards (domain filters, safety classifiers) could reduce misuse.
  • Scalability and costs: Building and maintaining the graph and multi-round Socratic loops may be computationally expensive; resource requirements are not reported.

📋 Summary

This paper introduces MotivGraph-SoIQ, a novel framework designed to enhance the ideation capabilities of Large Language Models (LLMs) in academic research. The core contribution lies in addressing two critical challenges: the lack of robust theoretical grounding in LLM-generated ideas and the presence of confirmation bias that hinders the refinement of these ideas. To tackle these issues, the authors propose an integrated approach combining a Motivational Knowledge Graph (MotivGraph) and a Q-Driven Socratic Ideator. The MotivGraph, constructed using SciMotivMiner, is a structured representation of academic knowledge, comprising problem, challenge, and solution nodes extracted from scientific literature. This graph aims to provide a solid foundation for LLMs by offering relevant context and inspiration. The Q-Driven Socratic Ideator, on the other hand, is a dual-agent system consisting of a researcher and a mentor. The researcher explores the MotivGraph and generates initial ideas, while the mentor employs Socratic questioning to critically evaluate and refine these ideas, mitigating confirmation bias. The framework operates in two phases: an exploration phase where the researcher agent gathers information from the MotivGraph and Semantic Scholar, and a deliberation phase where the mentor agent challenges the researcher's ideas. The authors evaluate their framework on a dataset of ICLR 2025 paper topics, comparing it against several baselines, including AI-Scientist-v2, ResearchAgent, and CycleResearcher. The results, assessed through both LLM-based evaluations and human evaluations, demonstrate that MotivGraph-SoIQ outperforms these baselines in terms of novelty, experimental feasibility, motivational rationality, and diversity. The paper also includes ablation studies to validate the contribution of individual components of the framework. Overall, this work presents a significant step towards leveraging LLMs for academic ideation by providing a structured and critical approach to idea generation.

✅ Strengths

I find several aspects of this paper to be particularly strong. The core idea of integrating a motivational knowledge graph with a Socratic dialogue framework is both novel and well-motivated. The authors have identified a significant gap in the current application of LLMs for academic research, namely the lack of grounding and the presence of confirmation bias, and have proposed a creative solution to address these issues. The construction of the MotivGraph using SciMotivMiner is a valuable contribution, as it provides a structured representation of academic knowledge that can be used to guide the ideation process. The use of a dual-agent system, with a researcher and a mentor, is also a clever approach to mitigating confirmation bias. The mentor agent's role in critically evaluating and refining the researcher's ideas through Socratic questioning is a key strength of the framework. Furthermore, the empirical results presented in the paper are compelling. The authors have conducted a thorough evaluation of their framework, comparing it against several strong baselines. The results, which include both LLM-based and human evaluations, consistently demonstrate that MotivGraph-SoIQ outperforms these baselines in terms of novelty, experimental feasibility, motivational rationality, and diversity. The ablation studies also provide valuable insights into the contribution of individual components of the framework. The paper is also well-written and clearly explains the proposed method and the experimental setup. The authors have provided sufficient details to allow for reproducibility, and the figures and tables are helpful in understanding the results. Overall, I believe that this paper makes a significant contribution to the field of LLM-based academic ideation, and I am impressed by the creativity and rigor of the proposed approach.

❌ Weaknesses

Despite the strengths of this paper, I have identified several weaknesses that warrant further discussion. Firstly, the paper's evaluation, while thorough, is limited by its reliance on a single dataset of ICLR 2025 paper topics. While the authors do test on a dataset from a different domain (medical), the primary evaluation is confined to a single conference. This raises concerns about the generalizability of the proposed method to other research domains and problem types. As the 'EXPERIMENT' section indicates, the evaluation is based on topics from ICLR 2025, and while the 'Generalizability to Other Scientific Domains' section presents results from a medical dataset, the main evaluation remains focused on ICLR. This limitation is significant because the structure and nature of research problems can vary greatly across different fields, and it is unclear whether the MotivGraph, which is constructed from ICLR papers, would be equally effective in other domains. Secondly, the paper lacks a detailed analysis of the computational cost and efficiency of the proposed method. The 'EXPERIMENT' section provides the average length of generated ideas, which can be a proxy for computational cost, but there is no explicit discussion of the time or resources required for the method, especially in comparison to the baseline methods. This is a critical omission, as the practical applicability of the method depends on its computational feasibility. Without a clear understanding of the computational overhead, it is difficult to assess the trade-offs between the quality of the generated ideas and the resources required to produce them. Thirdly, the paper does not provide a detailed analysis of the types of ideas generated by the framework. While the 'EXPERIMENT' section mentions that ideas are evaluated for novelty, experimental feasibility, and motivational rationality, there is no in-depth analysis of the characteristics of the generated ideas. For example, it is unclear whether the framework is more effective at generating theoretical or applied ideas, or whether it is better at addressing certain types of research problems. This lack of analysis makes it difficult to understand the strengths and limitations of the proposed method and to identify areas for future improvement. Fourthly, the paper does not adequately address the potential for the framework to perpetuate existing biases in the training data. The 'MOTIVATION' section acknowledges the probabilistic and biased nature of LLMs, but the paper does not discuss how the framework might inadvertently reinforce these biases. This is a significant concern, as it could lead to the generation of ideas that are not truly novel or that reflect existing prejudices. Fifthly, the paper lacks a detailed analysis of the knowledge graph's quality. While the 'MOTIVATION' section describes the construction of the MotivGraph using SciMotivMiner, there is no explicit discussion of the graph's quality, coverage, or potential biases. This is a critical omission, as the quality of the knowledge graph directly impacts the effectiveness of the ideation process. Without a clear understanding of the graph's limitations, it is difficult to assess the reliability of the generated ideas. Sixthly, the paper does not provide a detailed analysis of the Socratic dialogue process. While the 'Q-Driven Socratic Ideator' section describes the interaction between the researcher and mentor agents, there is no analysis of the types of questions asked, the effectiveness of different questioning strategies, or the impact of the dialogue on the quality of the generated ideas. This lack of analysis makes it difficult to understand how the Socratic dialogue contributes to the mitigation of confirmation bias and the improvement of idea quality. Finally, the paper does not provide a detailed analysis of the errors made by the framework. While the 'EXPERIMENT' section presents overall performance metrics, there is no discussion of the types of errors that the framework makes, such as generating ideas that are not novel or that are not feasible. This lack of error analysis makes it difficult to identify areas for improvement and to understand the limitations of the proposed method. The paper also lacks a discussion of the ethical implications of using LLMs for academic ideation, including the potential for misuse and the impact on the academic community. This is a critical omission, as the increasing use of LLMs in research raises important ethical questions that need to be addressed.

💡 Suggestions

To address the identified weaknesses, I recommend several concrete improvements. Firstly, the authors should conduct a more thorough evaluation of their method across a wider range of datasets, including datasets from different scientific domains and with varying levels of complexity. This would provide a more robust assessment of the method's generalizability and its ability to handle diverse research problems. For example, datasets from fields such as biology, chemistry, or social sciences could be used to test the method's performance in different contexts. Secondly, the authors should provide a detailed analysis of the computational cost and efficiency of their method. This should include a breakdown of the time and resources required for each step of the process, such as graph construction, idea generation, and evaluation. This analysis should also compare the computational cost of the proposed method with that of the baseline methods, to provide a clear understanding of the trade-offs between performance and efficiency. Thirdly, the authors should conduct a more detailed analysis of the types of ideas generated by the framework. This should include an analysis of the characteristics of the generated ideas, such as whether they are theoretical or applied, and whether they address specific types of research problems. This analysis could also explore the relationship between the structure of the knowledge graph and the types of ideas that are generated. Fourthly, the authors should address the potential for the framework to perpetuate existing biases in the training data. This could involve exploring techniques for bias mitigation, such as using diverse training data or incorporating fairness constraints into the model. The authors should also discuss the potential ethical implications of using LLMs for academic ideation, including the potential for misuse and the impact on the academic community. Fifthly, the authors should provide a more detailed analysis of the knowledge graph's quality, including its coverage, accuracy, and potential biases. This analysis should also discuss the limitations of the graph and how these limitations might affect the performance of the framework. Sixthly, the authors should provide a more detailed analysis of the Socratic dialogue process, including the types of questions asked, the effectiveness of different questioning strategies, and the impact of the dialogue on the quality of the generated ideas. This analysis could also explore the relationship between the Socratic dialogue and the mitigation of confirmation bias. Finally, the authors should provide a detailed analysis of the errors made by the framework, including the types of errors and their frequency. This analysis could help to identify areas for improvement and to understand the limitations of the proposed method. In addition to these specific recommendations, I also suggest that the authors consider exploring the potential for human-in-the-loop interaction in their framework. While the current approach focuses on automated ideation, human researchers could provide valuable feedback and guidance, which could further enhance the quality and relevance of the generated ideas. The authors could also explore the potential for using their framework to support collaborative research, by enabling multiple researchers to contribute to the ideation process.

❓ Questions

I have several questions that arise from my analysis of this paper. Firstly, how does the performance of the MotivGraph-SoIQ framework vary across different research domains? While the paper presents results from a medical dataset, I am curious about the framework's performance in other fields, such as biology, chemistry, or social sciences. Secondly, what is the computational cost of constructing and maintaining the MotivGraph, and how does this cost scale with the size of the dataset? I am also interested in the computational cost of the Socratic dialogue process, and how this cost compares to that of the baseline methods. Thirdly, what are the specific characteristics of the ideas generated by the framework, and how do these characteristics vary depending on the input topic and the structure of the knowledge graph? I am particularly interested in whether the framework is more effective at generating theoretical or applied ideas, and whether it is better at addressing certain types of research problems. Fourthly, what are the specific types of biases that might be present in the training data, and how might these biases affect the quality and diversity of the generated ideas? I am also interested in the techniques that could be used to mitigate these biases. Fifthly, what are the specific types of questions that are most effective in the Socratic dialogue process, and how can the questioning strategies be optimized to improve the quality of the generated ideas? I am also interested in the relationship between the Socratic dialogue and the mitigation of confirmation bias. Finally, what are the most common types of errors made by the framework, and what are the underlying causes of these errors? I am also interested in the techniques that could be used to reduce the frequency of these errors. These questions are aimed at clarifying key uncertainties and methodological choices, and I believe that addressing them would further strengthen the paper.
