Abstract: The disclosure discloses a method and an apparatus for processing identity information, an electronic device, and a storage medium, and relates to a field of data processing technologies. The detailed implementation includes: obtaining first association relationships between identities and entity objects from a plurality of information sources; establishing a relationship graph corresponding to each information source based on at least one first association relationship obtained from each information source; generating a virtual node associated with at least two entity objects in different relationship graphs based on a space-time distance between respective entity objects; and determining a second association relationship between identities involved in different relationship graphs based on the relationship graphs associated with the virtual node.

Abstract: The present application discloses a text query method and apparatus, device and storage medium, and relates to the field of intelligent search technology. A specific implementation scheme includes: identifying intention information and feature information of a query text, where the intention information is used to indicate intention of the query text; according to the intention information, determining a query interface for querying the intention; and querying a query result matching the feature information in information corresponding to the intention through the query interface. The present application can improve query efficiency of text query.
