CREWAI RAG LANGCHAIN QDRANT 🤼

crewai

This repository contains a full Q&A pipeline using LangChain framework, Qdrant as vector database and CrewAI as Agents. The data used is "The Attention Mechanism" research paper, but the RAG pipeline is structure to analyze research papers and provide an analysis and summary. Therefore it can use any other research paper. Use this Link if the notebook cannot be opened.

The main steps taken to build the RAG pipeline can be summarize as follows:

  • Data Ingestion: load data from pdf file

  • Indexing: RecursiveCharacterTextSplitter for indexing in chunks

  • Vector Store: Qdrant inserting metadata

  • QA Chain Retrieval: RetrievalQA

  • CrewAI: Researcher and Writer Agents to analyze and summarize the paper

📐 Set Up

In the initial project phase, the documents are loaded using PyPDFLoader and indexed. Indexing is a fundamental process for storing and organizing data from diverse sources into a vector store, a structure essential for efficient storage and retrieval. This process involves the following steps:

  • Select a splitting method and its hyperparameters: we will use the RecursiveCharacterTextSplitter.

  • Select the embeddings model: in our case the OpenAI

  • Select a Vector Store: Qdrant.

Storing text chunks along with their corresponding embedding representations, capturing the semantic meaning of the text. These embeddings facilitate easy retrieval of chunks based on their semantic similarity.

After indexing, a QA Chain Retrieval Pipeline is set up in order to check the Q&A functioning and performance.

The final step includes CrewAI Agents to generate two documents:

  • An analysis of the paper provided by the research agent

  • A summary of the key findings provided by the writer

🌊 QA Chain Retrieval Pipeline

The pipeline created contains the main llm model, the QA chain and the agents. A custom tool which uses the vector store as search engine has been implemented. The researcher looks for the paper and generates a detailed analysis as md file. Finally the writer generates a short summary with the key findings of the paper, trying to write it in a way that it is comprehesive for computer science students.
