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。
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.
