Libraries Utilized

The Chat with PDFs project extensively employs the following key libraries:

• Streamlit: The web application is built upon the Streamlit framework, facilitating a user-friendly interface.
• PyPDF2: PDF content extraction is made possible by PyPDF2's PdfReader, enhancing text processing capabilities.
• HuggingFace: The BAAI/bge-small-en model from HuggingFace is instrumental in embedding text segments and forming a robust vector store.
• Langchain and ChatOpenAI: These components leverage the vector store to craft dynamic conversation chains, enabling engaging interactions.

Workflow

The workflow of Chat with PDFs is as follows:

1. The Streamlit-based web application is both developed and hosted, serving as the entry point for users to submit one or multiple PDF files.
2. Utilizing PyPDF2's PdfReader, the application extracts textual content from the uploaded PDFs, subsequently forwarding it to the CharacterTextSplitter component.
3. CharacterTextSplitter takes charge of segmenting the extracted text into smaller, more manageable chunks, enhancing the subsequent processing steps.
4. The distinguished BAAI/bge-small-en model from HuggingFace is harnessed to embed the segmented text chunks, resulting in the creation of a comprehensive vector store.
5. This vector store proves pivotal in the construction of dynamic conversation chains through the combined utilization of Langchain and ChatOpenAI.
