Abstract: A method of extracting information from documents. The method simplifies the extraction of information from documents by first converting them into machine-readable text via OCR. It then employs a text embedding model to represent the text as high-dimensional vectors. These vectors are clustered to pinpoint natural groupings and representative document clusters. An example document from each cluster is chosen, guided by the number of non-empty fields and its relation to other documents. This selection informs the creation of an in-context-learning prompt, which includes accurately annotated labels and a system prompt defining the task for the LLM. The LLM is then prompted to extract information from a new document's OCR text, leveraging the constructed prompt for guidance.
