Rag mongodb langchain This project implements a Retrieval-Augmented Generation (RAG) system using LangChain embeddings and MongoDB as a vector database. Then you'll learn about several AI integrations and frameworks that can help you build a RAG application. It provided a clear, step-by-step approach to setting up a RAG application, including database creation, collection and index configuration, and utilizing LangChain to construct a RAG chain and application. These applications use a technique known as Retrieval Augmented Generation, or RAG. From there, those medium size chunks are split into small chunks. Oct 31, 2024 · RAG_Pattern. Jun 6, 2024 · I showed you how to connect your MongoDB database to LangChain and LlamaIndex separately, load the data, create embeddings, store them back to the MongoDB collection, and then execute a semantic search using MongoDB Atlas vector search capabilities. It does a more advanced form of RAG called Parent-Document Retrieval. This template performs RAG using MongoDB and OpenAI. Building a retrieval system involves searching for and returning the most relevant documents from your vector database to augment the LLM with. By implementing these tools, developers can ensure their AI chatbots deliver highly accurate and contextually relevant answers. In this form of retrieval, a large document is first split into medium sized chunks. These are applications that can answer questions about specific source information. Feb 14, 2024 · %pip install pymongo %pip install pypdf %pip install langchain %pip install langchain_community %pip install langchain_openai %pip install langchain_core. LangChain simplifies building the chatbot logic, while MongoDB Atlas' Vector database . 2. It supports native Vector Search, full text search (BM25), and hybrid search on your MongoDB document data. This tutorial demonstrates how to implement GraphRAG by using MongoDB Atlas and LangChain. Embeddings are created for the small chunks. Using Atlas Vector Search for RAG Unit Overview. The system processes PDF documents, splits the text into coherent chunks of up to 256 characters, stores them in MongoDB, and retrieves relevant chunks based on a prompt Users utilizing earlier versions of MongoDB Atlas need to pin their LangChain version to <=0. Feb 13, 2025 · There we have it—we used MongoDB with LangChain4j to create a simple RAG application. In order to use OpenAIEmbeddings, we need to set up our OpenAI API key. This guide outlines how to enhance Retrieval-Augmented Generation (RAG) applications with semantic caching and memory using MongoDB and LangChain. Specifically, you perform the following actions: This template performs RAG using MongoDB and OpenAI. While vector-based RAG finds documents that are semantically similar to the query, GraphRAG finds connected entities to the query and traverses the relationships in the graph to retrieve relevant information. To retrieve relevant documents with Atlas Vector Search, you convert the user's question into vector embeddings and run a vector search query against your data in Atlas to find documents with the most similar embeddings. In this guide, I’ll walk you through building a RAG chatbot using MongoDB as the database, Google Cloud Platform (GCP) for deployment, and Langchain to streamline retrieval and rag-mongo. View the GitHub repo for the implementation code. GraphRAG is an alternative approach to traditional RAG that structures your data as a knowledge graph instead of as vector embeddings. Sep 18, 2024 · This guide has simplified the process of incorporating memory into RAG applications through MongoDB and LangChain. 304 In the notebook we will demonstrate how to perform Retrieval Augmented Generation (RAG) using MongoDB Atlas, OpenAI and Langchain. First, you'll learn what RAG is. Environment Setup You should export two environment variables, one being your MongoDB URI, the other being your OpenAI API KEY. Sep 18, 2024 · In this article, we've explored the synergy of MongoDB Atlas Vector Search with LangChain Templates and the RAG pattern to significantly improve chatbot response quality. This tutorial demonstrates how to implement retrieval-augmented generation (RAG) with a local Atlas deployment, local models, and the LangChain MongoDB integration. py file. In this unit, you'll build a retrieval-augmented generation (RAG) application with LangChain and the MongoDB Python driver. RAG combines AI language generation with knowledge retrieval for more informative responses. One of the most powerful applications enabled by LLMs is sophisticated question-answering (Q&A) chatbots. MongoDB Atlas is a fully-managed cloud database available in AWS, Azure, and GCP. MongoDB Atlas. This starter template implements a Retrieval-Augmented Generation (RAG) chatbot using LangChain, MongoDB Atlas, and Render. When combined with an LLM, this approach enables relationship-aware retrieval and multi-hop reasoning. If you do not have a key, you can create one here. This notebook covers how to MongoDB Atlas vector search in LangChain, using the langchain-mongodb package. 0. This Python project demonstrates semantic search using MongoDB and two different LLM frameworks: LangChain and LlamaIndex. About. I have saved the OpenAI API key in key_params. LangChain4j abstracted away a lot of the steps along the way, from segmenting our data, to connecting to our MongoDB database and embedding model. It explains integrating semantic caching to improve response efficiency and relevance by storing query results based on semantics. Additionally, it describes adding memory for maintaining conversation history, enabling context-aware interactions This starter template implements a Retrieval-Augmented Generation (RAG) chatbot using LangChain and MongoDB Atlas. LangChain simplifies building the chatbot logic, while MongoDB Atlas' vector database capability provides a powerful platform for GraphRAG is an alternative approach to traditional RAG that structures data as a knowledge graph of entities and their relationships instead of as vector embeddings. If you do not have a MongoDB URI, see the Setup Mongo section at the bottom for instructions on how to do so. The goal is to load documents from MongoDB, generate embeddings for the text data, and perform semantic searches using both LangChain and LlamaIndex frameworks. hmfr auzcg jltd bunkf mfdwo rvoadjl kjvik xahrqi kgte uneqxlko
