| 摘 要： | 针对Web GIS中文查询语句中词义的多义性给查询语句的正确理解带来的困难,在系统语料库的基础上设计了能解决该问题的算法,提出了句子链栈的存储结构。测试结果证明了该算法能达到9 5%的正确率,为语义分析子系统能正确地提取查询目标、查询条件、分组信息和排序信息提供了有效的词义信息。

| Abstract: | In GIS Chinese inquiry system,the word meaning ambiguity has brought many troubles in understanding inquiry sentences correctly.The problem is analyzed carefully and a new algorithm is presented based on corpus which can solve ambiguity successfully.As an innovation,A new data structure,called "sentence link stack",is adopted in algorithm.The experimental results show that the algorithm can achieve accuracy of 95% and can offer valid information for the semantic analysis subsystem to draw inquiry targets,inquiry condition,group message and sort message. |
