Mastering Table Extraction: Revolutionize Your Earnings Reports Analysis with AI
Blog post from Unstructured
Quarterly earnings reports are crucial for investors but can be challenging to analyze due to their unstructured format, prompting the need for advanced technological solutions. Traditional AI models, such as ChatGPT, face difficulties in processing these vast and visually complex documents, leading to the exploration of Retrieval Augmented Generation (RAG) pipelines, enhanced by tools like Unstructured's library. This approach leverages the computational power of large language models (LLMs) and the memory capabilities of vector databases to extract and analyze table data from earnings reports, using LangChain, ChromaDB, and OpenAI's models. The process involves converting tables into HTML format for better LLM interpretation, chunking information to fit LLM context windows, and embedding the data for query-based analysis. While effective, the method encounters challenges like missing table titles in HTML outputs and issues with table extraction models when faced with varied row background colors, prompting ongoing optimizations and further development efforts.
