Abstract
The invention relates to a data query method and device based on a vector database. The method comprises the following steps: clustering vector data in a vector database, constructing a global clustering branch tree, segmenting the global clustering branch tree into a plurality of user clustering trees based on data distribution characteristics corresponding to each user, and after a query request input by a target user is received, sending the query request to the target user; traversing a user clustering tree corresponding to the target user based on the query request, and outputting a query result; according to the method, the global clustering branch tree is constructed, and the corresponding user clustering tree is customized for each user according to the data distribution characteristics of the user, so that efficient query in a multi-user vector database environment is realized.
