Latest Patents

Shujian Liu holds a patent titled "Hybrid retrieval augmented generation for rich document queries using a large language model." This patent discloses techniques for implementing hybrid retrieval augmented generation for rich document queries using a large language model (LLM). In his method, a computing system receives documents that are added to databases. The system then receives a query, from which tokens are generated. It determines a first ranking of the documents using a probabilistic ranking method and a second ranking in response to a vector database query using an embedded representation. The system combines these rankings to select top documents and determines a knowledge graph based on them. Finally, it outputs the query, the top documents, and a portion of the knowledge graph to the LLM, receiving and outputting a response.
