š¤ Build a chatbot using Langchain, OpenAI ChatGPT, and Pinecone.
š ChatGPT can answer from internal company documents or knowledge base.
š” Refine queries to get relevant context for semantic search in Pinecone.
š¤ In this video, we combine GPT4 conversational capability with our own document semantic search using Pinecone.
š We create an index and process documents using the Sentence Transformer model and store vectors to perform semantic search.
š¬ We utilize Streamlit to build a conversational chat application that retrieves answers from the Pinecone index knowledge base.
š Splitting the text into chunks with overlapping context.
š§© Using Pinecone to create embeddings and index the documents.
š Performing similarity search to find related chunks.
š We are using Langchain chatbot instead of plain OpenAI for our project, as it supports conversation chains and memory.
š¬ To create the chatbot, we require different prompts for system messages, human queries, and chat responses.
š„ļø We are using Streamlit for the user interface, where we display the responses and queries in a visually appealing way.
š Maintaining only the recent three or four conversations in a chatbot.
ā” Using conversation buffer window memory to store the last three messages.
š¬ Combining system prompts, message placeholders, and conversation history in chat prompt templates.
āØ The conversation chain uses Pinecone indexing to find matching documents based on a given query.
š¬ The conversation chain predicts responses using ChatGPT and stores them in session variables for display.
š The refined prompt transforms the current query using previous conversation logs to enable semantic search.
š¤ The video discusses the use of chatbots powered by Langchain, ChatGPT, Pinecone, and Streamlit to answer questions from a knowledge base.
š The chatbot can generate refined queries based on user conversations and current queries, providing more meaningful search results.
š The video mentions the availability of code and blog posts for further information on Langchain, Pinecone, and other related topics.
