Base on ChatGLM+Chromadb+Langchain+Streamlit to build a PDF chatbot! (Hopefully, word,excel,markdown,txt...will be introduced.Stay tuned!)
The MultiPDF Chat App is a Python application that allows you to chat with multiple PDF documents. You can ask questions about the PDFs using natural language, and the application will provide relevant responses based on the content of the documents. This app utilizes a language model to generate accurate answers to your queries. Please note that the app will only respond to questions related to the loaded PDFs.
Click Click ME to have a try on this real-time PDF-Chatbot.
The application follows these steps to provide responses to your questions:
-
PDF Loading: The app reads multiple PDF documents and extracts their text content.
-
Text Chunking: The extracted text is divided into smaller chunks that can be processed effectively.
-
Language Model: The application utilizes a language model to generate vector representations (embeddings) of the text chunks.
-
Similarity Matching: When you ask a question, the app compares it with the text chunks and identifies the most semantically similar ones.
-
Response Generation: The selected chunks are passed to the language model, which generates a response based on the relevant content of the PDFs.

基于ChatGLM+Chromadb+Langchain+Streamlight构建一个PDF聊天机器人！(希望能介绍Word、Excel、Markdown、txt……，敬请关注！)。
MultiPDF聊天应用程序是一款允许您与多个PDF文档聊天的Python应用程序。您可以使用自然语言询问有关PDF的问题，应用程序将根据文档内容提供相关回答。这款应用程序使用语言模型来生成对您的查询的准确答案。请注意，该应用程序只会回答与加载的PDF相关的问题。
点我快点我试试此实时PDF-chatbot！
应用程序遵循以下步骤为您的问题提供答复：
1.PDF加载：该应用程序读取多个PDF文档，并提取其文本内容。
2.文本组块：将提取的文本分成可以有效处理的小块。
3.语言模型：应用程序利用语言模型来生成文本块的矢量表示(嵌入)。
4.相似度匹配：当你问一个问题时，应用程序会将它与文本块进行比较，并找出语义上最相似的。
5.响应生成：将选择的组块传递给语言模型，语言模型根据PDF的相关内容生成响应。
