🔍 This video demonstrates the use of LangChain and ChromaDB for retrieving QA over multiple documents.
💾 A database is created using ChromaDB to store multiple text files, and a citation information is included for query results.
🆕 The video also introduces the usage of the new GPT-3.5-turbo API for language model and embeddings.
📁 The first step is to set the directory and gather the files, with different loaders for different file types.
🔨 The data is then split into chunks and a vector store is created to store the embeddings.
💾 The embeddings are generated from the documents and saved to a database, which can be loaded later.
🔍 By saving a vector database, we can reuse it instead of embedding all documents every time.
📚 Using a retriever, relevant documents can be retrieved based on queries and the number of documents can be adjusted.
🔢 Different search types and multiple indexes can be utilized for more advanced retrieval.
🔍 The video discusses the setup of a language model chain for retrieval QA over multiple files.
💡 The process involves passing the retriever and conducting a query to obtain relevant documents.
💰 The example query asks about the amount of money raised by a company, and the retrieved documents provide the desired information.
💡 LangChain retrieval QA allows for easy access to original source HTML pages.
🔍 The retrieval QA function provides detailed information about news articles and their sources.
📚 Generative AI and the acquisition of Okera are also discussed in the video.
🔑 CMA stands for the competition and markets authority.
🔑 The chain retriever type is similarity.
🔑 The chromaDB is used as the vector store.
