Inventor includes Sibin Kunnumpurath James.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: Method and system (106) for implementing RAG with improved context identification from semi-structured documents is disclosed. A target document is preprocessed by segmenting into individual pages. Text content from each individual page is extracted and processed through a domain-specific token filter to identify terms matching a stored domain-specific dictionary, and generate filtered page content comprising the matching terms. A page vector representation of the filtered page is computed, and vector similarity is performed between each page vector representation and stored vectors in a vector database that are associated with predefined entity types via entity labels that are extracted from matched templates. The entity labels are mapped to corresponding document pages based on similarity scores. A user query is analyzed using a Large Language Model (LLM) to identify relevant entity labels and pages with the relevant entity labels to generate a response.
