基于社交的空间文本skyline查询
Social-based spatial-textual skyline query
摘要
Abstract
Social information is applied to the spatial-textual skyline query , and a social-based spatial-textual skyline ( SSTS) query is proposed .The selection of the skyline object in the SSTS query depends on three aspects: the spatial distance between the object and the query user , the textual relevance of the keywords and the popularity of users.One new function is introduced to the query to compute the social relevance .In order to improve the satis-faction of the query , the SSTS query is extended , and a constrained social-based spatial-textual skyline ( CSSTS ) query is proposed .In addition, a novel concept of constrained skyline is introduced .For each query , the pruning strategies and termination conditions are used to improve the query efficiency .In the end , an experiment is per-formed to verify the proposed method ' s effectiveness .关键词
