Computer-implemented data mining method and device, electronic equipment and storage medium

The invention provides a computer-implemented data mining method and device, electronic equipment and a storage medium, and relates to the technical field of computers, in particular to the technical field of artificial intelligence and natural language processing. According to the implementation scheme, a user input text data set in a dialogue scene of a target domain and an entity dictionary of the target domain are obtained; identifying a first question text in the text data set input by the user; extracting a first entity vocabulary in the first question text; obtaining a first upper vocabulary corresponding to the first entity vocabulary based on an entity dictionary; replacing a first entity vocabulary in the first question text with a vocabulary slot corresponding to the first upper vocabulary to obtain a question template; based on the question template and a plurality of second entity vocabularies corresponding to the first upper vocabularies in the entity dictionary, obtaining a plurality of extende
