[Introduction] research-agent: A Phased Retrieval-Augmented Research Agent for Efficient LLM Reasoning Papers

research-agent is a retrieval-augmented research agent project developed by FromIron829 on GitHub, focusing on efficient LLM reasoning papers. It adopts a 4-stage phased construction methodology, optimizes retrieval performance through experiment-driven approaches, and has both educational and practical value, providing a clear path for RAG learning and research.

Section 02

Project Background and Overview

Unlike general RAG demos, this project uses a phased construction methodology to build a complete research assistant system from scratch, making it easy to learn and understand RAG components and optimization comparisons.

Section 03

Phased Architecture Design (Methodology)

The system is built in four stages:

  1. Stage0: Corpus reproduction (collecting and organizing LLM reasoning papers, standardized document processing, building benchmark datasets)
  2. Stage1: RAG pipeline construction (document loading and parsing, text chunking, vectorization indexing, basic retrieval logic)
  3. Stage2: Multi-experiment retrieval comparison
  4. Stage3: Agent layer construction (multi-turn dialogue, tool calling, reasoning chain, memory management)

Section 04

Experimental Evidence (Comparison of Multiple Retrieval Strategies)

Stage2 optimizes retrieval performance through comparative experiments:

  • Different text chunking strategies (fixed length, semantic splitting, recursive splitting, etc.)
  • Different embedding models (OpenAI, Sentence-BERT, domain-specific models, etc.)
  • Different retrieval algorithms (vector similarity, BM25, hybrid retrieval, etc.)
  • Impact of re-ranking on results

Quantify the contribution of each component to support data-driven optimization decisions.

Learning and Practice Recommendations

Recommendations for beginner RAG developers:

  1. First understand the importance of corpus construction
  2. Master the implementation of basic RAG pipelines
  3. Find retrieval strategies suitable for the scenario through experiments
  4. Upgrade to an intelligent assistant with agent capabilities
