Abstract
A processor executes a two-stage ranking process, and the processor executes tensor search to understand semantic of the tensor embeddings based on a predetermined similarity and obtain top k (k is a natural number) nodes and edges from a tensor database, based on a vector query, and graph search to search a graph database to check relationships between the obtained edges and nodes and other entities and obtain a context from the relationships, and combines a result of the tensor search and a result of the graph search by calculating a composite score based on tensor scores indicating semantics of top k nodes and edges obtained from the tensor database and graph scores indicating relationships obtained from the graph database, creates a prompt from the top k nodes, and generates an answer using a large-scale language model in response to the prompt.
