Abstract:

Based on the efficiency and effectiveness issue of traditional simiar spatial textual objects retrieval, a semantic aware strategy which can effectively and efficiently retrieve the top-k similar spatial textal objects is proposed. The efficient retrieval strategy which is based on spatial textual objects is built on a common framework of spatial object retrieval, and it can satisfy the efficiency and effectiveness issues of users. Extensive experimental evaluation demonstrates that the performance of the proposed method outperforms the state-of-the-art approach.

摘要： 针对传统空间文本检索策略中的效率和有效性问题, 对如何从给定的空间文本对象集合中快速有效地检索出top-k个近似结果进行研究。基于一个空间检索的通用框架, 提出一种基于空间文本对象的快速策略, 用于满足用户对效率与有效性的要求。实验结果证明该策略优于现有方法。
