How does ChatPDF work?

Text Extraction and Preprocessing
ChatPDF first extracts text from the uploaded PDF files, converting the text, images, and table information into a format that machines can recognize, while removing unnecessary formatting and noise, laying the groundwork for subsequent processing.
Natural Language Processing (NLP) Technology
ChatPDF uses NLP technology to analyze the extracted text, identifying the structure of the document, key concepts, entities, and relationships between sentences. NLP processing includes tokenization, part-of-speech tagging, and syntactic analysis, providing support for AI to generate accurate responses.
Retrieval-Augmented Generation (RAG) Technology
ChatPDF applies Retrieval-Augmented Generation (RAG) technology to match users' questions with relevant information in the document. It first uses a retrieval module (such as semantic search) to find the most relevant paragraphs, then the generation module produces precise answers. This combination ensures answer accuracy while flexibly addressing various inquiries.
Semantic Understanding and Context Matching
ChatPDF utilizes deep learning models to understand user query intentions and find relevant content in documents, accurately pinpointing the source paragraphs of answers through semantic matching algorithms for precise responses.
AI-Generated Responses
ChatPDF leverages advanced generative AI technologies (such as Transformer models) to generate answers, transforming complex content into clear, understandable statements. Additionally, the generated responses are optimized to ensure brevity and accuracy.
Document Summary Generation
Using semantic clustering and content filtering techniques, ChatPDF can automatically identify the main content of documents and generate concise summaries to help users quickly grasp the core information of lengthy texts.
Security and Privacy Protection
ChatPDF encrypts users' documents throughout the process, ensuring data security. Moreover, the model design adheres to privacy protection principles, not storing user files, and all operations are conducted in a secure environment.
