摘　　要：介绍了本体、地理本体和地名本体的基本概念,探讨了在文本工程通用框架GATE(GeneralArchitecture for Text Engineering)下,以自然语言处理为基础,借助地名本体,完成Web文本的中文地名识别与歧义消除的关键问题,设计并实现了一个原型系统。通过geo/non-geo和geo/geo地名歧义的消除,使得识别出来的地名与地球表面具体的地理位置相对应,进而为Web文本中的中国行政区划地名赋予地理坐标和地理语义。做了验证实验,并对实验结果进行了分析。This paper introduces the concepts of ontology,geographic ontology and toponym ontology,discusses some key issues on recognition and disambiguation Chinese toponyms from Web texts based on natural language processing using toponym ontology under GATE（General Architecture for Text Engineering） framework,designs and implements a prototype system.By eliminating the geo/non-geo and geo/geo ambiguities,rich semantics and precise geographical coordinates are given to the extracted toponyms which correspond to the locations on the earth＇s surface.At last,an experiment is made and the result is analyzed.
