Build "Sherlock PDF" with LangChain for Smarter Scientific Literature Search

This tutorial demonstrates how to build a tool called "Sherlock PDF" using LangChain to search through scientific literature stored in PDF format. The application allows users to ask questions in natural language and retrieves the most relevant passages, along with their source filenames and page numbers. It utilizes LangChain's components for loading, splitting, embedding, and vector searching documents, with cosine similarity used to determine passage relevance. AI

IMPACT Enables researchers to more efficiently find and cite information within large document sets.
