SEMANTIC UNDERSTANDING-BASED POINT OF INTEREST QUERY METHOD, DEVICE AND COMPUTING APPARATUS

摘要

The present application discloses a semantic understanding-based point of interest query method, comprising: acquiring a plurality of points of interest in a specified database in a financial field; on the basis of an information description in each point of interest, respectively matching a topic distribution probability for each point of interest; building an index path on the basis of the topic distribution probability and a geographical location; and filtering on the basis of the index path to obtain point of interest information similar to a query body. The POI search technique of the present application integrates semantic understanding and thereby improves matching between result content and search intention.
