Abstract
This study proposes a framework for automating the knowledge synthesis phase of Systematic Literature Reviews (SLRs) using fine-tuned Large Language Models (LLMs). The key highlights are: Devised a methodical approach to automatically extract datasets from selected academic papers for fine-tuning LLMs, including paper-level and SLR-level question-answer pairs. Proposed mechanisms to mitigate LLM hallucination and ensure traceability of LLM responses to source studies. Developed evaluation metrics to assess the factual accuracy of LLM responses, including FEVER and a Consistency Grading Scale. Benchmarked various fine-tuning approaches, including LoRA and NEFTune, and integrated Retrieval-Augmented Generation (RAG) to enhance factual accuracy. Demonstrated the efficacy of the proposed framework by replicating a published PRISMA-conforming SLR on learning analytics dashboards. Advocated for updating PRISMA reporting guidelines to incorporate AI-driven processes, ensuring methodological transparency and reliability in future SLRs. Released a Python package to facilitate data curation for LLM fine-tuning, tailored for the unique requirements of SLRs. The findings confirm the potential of fine-tuned LLMs in streamlining the labor-intensive knowledge synthesis process of literature reviews, setting a new standard for conducting comprehensive and accurate SLRs with more efficiency.

Deeper Inquiries

How can the proposed SLR-automation framework be extended to incorporate other AI techniques beyond LLMs, such as knowledge graphs or reinforcement learning, to further enhance the synthesis capabilities?

In order to enhance the synthesis capabilities of the proposed SLR-automation framework, incorporating other AI techniques beyond LLMs like knowledge graphs and reinforcement learning can be highly beneficial. Here are some ways in which these techniques can be integrated: Knowledge Graphs: Data Integration: Knowledge graphs can be used to integrate data from various sources, providing a structured representation of the relationships between different concepts in the SLR domain. Semantic Understanding: By leveraging knowledge graphs, the framework can gain a deeper semantic understanding of the content within the SLR papers, enabling more accurate information retrieval and synthesis. Contextual Relevance: Knowledge graphs can help in establishing contextual relevance between different pieces of information, aiding in the generation of more coherent and context-aware responses. Reinforcement Learning: Optimization of Responses: Reinforcement learning can be utilized to optimize the responses generated by the LLMs, ensuring that the synthesized information is more accurate and relevant to the research questions. Adaptive Learning: By incorporating reinforcement learning, the framework can adapt and improve over time based on feedback received, leading to more refined and effective synthesis of knowledge. Decision Making: Reinforcement learning algorithms can assist in decision-making processes within the framework, guiding the selection of the most appropriate responses and enhancing the overall quality of the SLR automation process. By integrating knowledge graphs for data integration and semantic understanding, and leveraging reinforcement learning for response optimization and adaptive learning, the SLR-automation framework can achieve a more comprehensive and sophisticated approach to knowledge synthesis.

What are the potential ethical and transparency concerns in using AI-driven processes for academic research, and how can they be addressed to ensure the integrity and trustworthiness of the SLR outcomes?

When utilizing AI-driven processes for academic research, there are several ethical and transparency concerns that need to be addressed to uphold the integrity and trustworthiness of the SLR outcomes. Some of these concerns include: Bias and Fairness: AI models can inherit biases from the data they are trained on, leading to biased outcomes. It is essential to regularly audit and mitigate biases in the AI models to ensure fair and unbiased results. Transparency: The inner workings of AI models, especially large language models, can be complex and opaque. Ensuring transparency in the decision-making process of these models is crucial for understanding how conclusions are reached. Data Privacy: Academic research often involves sensitive data. Maintaining data privacy and security throughout the AI-driven processes is paramount to protect the confidentiality of research participants. Accountability: Establishing clear accountability for the decisions made by AI models is essential. Researchers should be able to trace back the reasoning behind the AI-generated outcomes to ensure accountability. To address these concerns and ensure the integrity and trustworthiness of SLR outcomes, the following measures can be implemented: Ethical Guidelines: Establish clear ethical guidelines for the use of AI in academic research, outlining principles for fairness, transparency, and accountability. Algorithmic Audits: Conduct regular audits of AI algorithms to identify and mitigate biases, ensuring that the outcomes are fair and unbiased. Data Governance: Implement robust data governance practices to protect data privacy and security throughout the research process. Explainable AI: Utilize explainable AI techniques to make the decision-making process of AI models more transparent and understandable to researchers and stakeholders. By proactively addressing these ethical and transparency concerns and implementing measures to ensure fairness, transparency, and accountability, the integrity and trustworthiness of SLR outcomes can be safeguarded when using AI-driven processes.
