Chat with ArXiv

Build intelligent agents that understand, discuss, and synthesize academic research papers from ArXiv, enabling conversational exploration of scientific literature.

Overview

ArXiv chat agents combine:

• Paper Discovery: Search and retrieve relevant research
• Content Processing: Extract and understand paper content
• Question Answering: Answer questions about papers
• Research Synthesis: Identify connections between papers
• Conversational Interface: Natural discussion about research

Applications

• Research assistant for literature review
• Paper summarization and explanation
• Topic exploration across multiple papers
• Citation analysis and connection finding
• Trend identification in research areas
• Thesis and dissertation support

Paper Discovery and Retrieval

1. ArXiv API Integration

See examples/arxiv_paper_retriever.py for ArXivPaperRetriever:

• Search papers by query with relevance ranking
• Search by category, author, or title keywords
• Retrieve trending papers by category and date range
• Find similar papers to a given paper
• Extract key terms from paper abstracts

2. Paper Content Processing

See examples/paper_content_processor.py for PaperContentProcessor:

• Download and extract PDF content
• Parse paper structure (abstract, introduction, methodology, results, conclusion, references)
• Extract citations from papers
• Cache processed papers for performance
• Chunk papers for RAG integration

Question Answering System

1. RAG-Based QA

See examples/paper_question_answerer.py for PaperQuestionAnswerer:

• Search for relevant papers from ArXiv
• Download and process papers
• Chunk papers for RAG retrieval
• Retrieve most relevant chunks using embeddings
• Generate answers with proper citations

2. Multi-Paper Synthesis

Build synthesis capabilities to:

• Analyze multiple papers on a topic
• Extract key findings and conclusions
• Identify common research themes
• Generate comprehensive synthesis of research area

Conversational Interface

1. Multi-Turn Conversation

See examples/arxiv_chatbot.py for ArXivChatbot:

• Maintain conversation history
• Classify query types (single paper Q&A, multi-paper synthesis, trends, general)
• Handle single paper questions with citations
• Handle synthesis queries across multiple papers
• Detect and retrieve research trends
• Generate contextual responses

2. Context Management

Build context management to:

• Track current discussion topic
• Remember discussed papers
• Find related papers in conversation
• Summarize discussion progress

Best Practices

Paper Retrieval

• ✓ Use specific queries for better results
• ✓ Limit results to relevant papers (max 50-100)
• ✓ Cache downloaded papers locally
• ✓ Handle API rate limits
• ✓ Validate PDF extraction

Question Answering

• ✓ Always cite sources with ArXiv IDs
• ✓ Use multiple paper perspectives
• ✓ Acknowledge uncertainties
• ✓ Highlight conflicting findings
• ✓ Suggest related papers

Conversation Management

• ✓ Maintain conversation history
• ✓ Track discussed papers
• ✓ Clarify ambiguous queries
• ✓ Suggest follow-up questions
• ✓ Provide paper recommendations
