Improving Answer Extraction in Context-based Question Answering Systems Using LLMs

Researchers propose an improved question answering system using fine-tuned large language models on the SQuAD dataset, achieving strong performance metrics (ROUGE-L: 86.84%, BERTScore: 95.38%). The work addresses limitations in current LLM-based QA systems' ability to extract accurate answers from given contexts, demonstrating that targeted fine-tuning substantially enhances reliability and precision.

LabelFusion: Fusing Large Language Models with Transformer Encoders for Robust Financial News Classification

Researchers developed LabelFusion, a hybrid AI architecture combining Large Language Models with transformer encoders for financial news classification. The system achieves 96% F1 score on full datasets but LLMs alone perform better in low-data scenarios, suggesting different strategies based on available training data.

A Two-Stage Architecture for NDA Analysis: LLM-based Segmentation and Transformer-based Clause Classification

Researchers developed a two-stage AI architecture using LLaMA-3.1-8B-Instruct and Legal-Roberta-Large models to automate the analysis of Non-Disclosure Agreements (NDAs). The system achieved high accuracy with ROUGE F1 of 0.95 for document segmentation and weighted F1 of 0.85 for clause classification, demonstrating potential for automating legal document analysis.
