Intelligent Academic Paper Analysis System: An Automated Research Literature Processing Solution Based on Large Language Models

This article introduces an intelligent academic paper analysis system based on large language models (LLM), designed to address the problem of information overload in academic research. By automatically processing literature content, the system provides core functions such as intelligent summary generation, key information extraction, research trend analysis, similar paper recommendation, and Q&A interaction, which can significantly improve researchers' literature processing efficiency. As the final project for the CSC 7644 course, it demonstrates the application value of LLM technology in the academic field.

Nowadays, the speed of knowledge production in the academic field is surging; PubMed adds over 1 million papers annually, and the number of arXiv preprints is growing exponentially. Traditional literature retrieval and reading methods are inefficient and prone to missing important results. This system originated from the final project of the CSC 7644 (Applied Large Language Model Development) course, aiming to use LLM capabilities to solve real pain points for researchers and cultivate students' ability to apply LLM technology to practical problems.

The system adopts a modular layered architecture, including the user interaction layer (Web interface, API interface, batch processing module), business logic layer (document parser, task scheduler, result aggregator), LLM service layer (prompt engineering, model calling, output parsing), and data storage layer (vector database, document storage, metadata index). The document processing pipeline is divided into three stages: 1. Ingestion and parsing (supports PDF/LaTeX/plain text, extracts content and structure); 2. Preprocessing and chunking (semantic chunking, overlap strategy); 3. Vectorization and indexing (embedding model conversion, vector database storage).

The core functions of the system include: 1. Intelligent summary generation: hierarchical summarization (paragraph → chapter → full text), extractive-generative hybrid, multi-model integration; 2. Key information extraction: identify research entities (datasets, models, etc.) and relationships, understand tables and charts; 3. Research trend analysis: time-series tracking of topic evolution and method popularity, cluster visualization to discover research communities; 4. Intelligent Q&A: based on RAG architecture (query understanding → retrieval → context assembly → answer generation), supporting multi-turn dialogue.

System performance evaluation dimensions: 1. Summary quality: ROUGE score, BERTScore, manual evaluation; 2. Information extraction: precision/recall/F1, error analysis; 3. Q&A system: relevance, factual accuracy, citation completeness. Optimization strategies include: prompt optimization (few-shot learning, instruction fine-tuning), retrieval optimization (query rewriting, re-ranking, hybrid retrieval).

System application scenarios: 1. Researcher assistant: accelerate literature review, assist in in-depth paper reading, writing reference; 2. Academic institution knowledge management: build institutional knowledge bases, analyze research directions, evaluate influence; 3. Publishers and database services: review assistance, metadata enhancement, recommendation system optimization.

Current limitations: LLM hallucination issues, long document processing difficulties, limited multilingual support, insufficient mathematical formula understanding. Future directions: multi-modal fusion (text + charts + code), personalized learning (interest modeling, active push), collaborative social functions (annotation sharing, collaborative review).
