Research on a Spatial Join Query with Keyword Search
支持关键词搜索的空间连接查询研究

In recent years,many real applications are required to support both spatial joins and keyword-based search.Motivated by such requirements,this paper defined a new kind of Spatial Join query with Keyword Search(SJKS) which combines both keyword-based search and spatial join.To answer SJKS efficiently,this paper constructed IR2-Tree(Information Retrieval R-Tree) indexing structures on the datasets,and presented an IR2-Tree-based SJKS processing algorithm named as IR2-TreeSJKS.The results of experiments show t...
