With the rapid development of Large Language Models (LLMs), Retrieval-Augmented Generation (RAG) has become a predominant method in the field of professional knowledge-based question answering. Presently, major foundation model companies have opened up Embedding and Chat API interfaces, and frameworks like Langchain have already integrated the RAG process. It appears that the key models and steps in RAG have been resolved, leading to the question: are professional knowledge QA systems now approaching perfection?
This article discovers that current primary methods depend on the premise of accessing high-quality text corpora. However, since professional documents are mainly stored in PDFs, the low accuracy of PDF parsing significantly impacts the effectiveness of professional knowledge-based QA.
We conducted an empirical RAG experiment across 188 real-world professional documents and 302 questions. The results showed that, ChatDOC, a RAG system equiped with panoptic and pinpoint PDF parser, retrieved more accurate and complete segments and answered superior to baseline on over 40% of questions. This shows that we may revolutionize RAG with enhanced PDF structure recognition.
Insights
Large Language Models (LLMs) are capable of producing more accurate responses when assisted by a PDF parser that effectively extracts and integrates structured information from documents into the prompts. This process enhances the quality and relevance of the data fed into the models, thereby improving their output.
