The article discusses building a 'smart documentation' chatbot by indexing documentation into manageable chunks, generating embeddings with OpenAI, and performing similarity search.
The purpose is to create a chatbot that can provide answers from documentation based on user queries, using Markdown files as an example.
The solution involves three main parts: reading documentation files, indexing the documentation through chunking and embedding, and searching the documentation.
Documentation files can be scanned from a folder or fetched from a database or CMS.
Indexing involves chunking documents, generating vector embeddings for each chunk, and storing embeddings locally.
Chunking is vital to prevent data exceeding model limits, while overlap ensures context continuity between chunks.
Vector embeddings from OpenAI are used for similarity searches between user queries and document chunks.
Cosine similarity is calculated to filter relevant document chunks based on user queries.
A small Express.js endpoint integrates OpenAI's Chat API to generate responses based on the most relevant document chunks.
The article provides code snippets and explains the process step by step, offering a template for building a chatbot with a chat-like interface.
