Retrieving context from previous sessions
Topics: Search Query Processing, Semantic Search
The Google patent describes a system for retrieving and using contextual data from previous conversation sessions in conversational searches. It utilizes a session index repository that associates identifiers for user sessions with tags and items, and a session data repository that stores contextual data for each session. When a new query is received, the system determines if it refers to tags in the index repository, retrieves relevant previous session data, and uses it to respond to the query. This allows the system to make conversational search smarter by seamlessly incorporating context from past interactions.
