| 摘 要： | 许多实际的应用需要同时支持空间连接查询和关键词搜索。在给出基于关键词的空间连接（KSJ）查询定义的基础上，对参与KSJ查询的空间数据集建立MIR2-树索引结构，并结合一些高效的搜索剪枝策略，提出一种基于宽度优先的KSJ查询算法。实验结果表明该算法可有效支持基于关键词的空间连接查询处理。

| Abstract: | Many applications are required to support both spatial joins and keyword-based search. This paper aims to present efficient methods to answer Keyword-based Spatial Join(KSJ) queries,constructs MIR2-tree indexing structures on the datasets for KSJ,and uses them to answer KSJ with breadth-first traversal method. In addition,some search pruning strategies are applied to enhance the efficiency of MIR2-tree traversing. Experimental results show that the algorithm is effective for keyword-based spatial join queri... |
