| 摘 要： | 电子政务主题词表是电子政务信息组织和检索的重要语义工具。传统手工编制叙词表的方法已不再适用于网络环境。电子政务词表的自动构建技术主要有基于N-gram方法的词汇收集和选择词间关系的自动识别。要想编制一部性能优越且容易应用的词表,应将计算机自动构建与传统方式编制结合起来,取长补短。表7。参考文献10。

| Abstract: | Thesauri for e-government are important semantic tools for the organization and retrieval of e-government information.Traditional manual thesaurus compilation methods are no longer suitable to the networked environment. Among the technologies for the automatic construction of e-government thesauri,there are the N-gram-based vocabulary- collecting technology and the automatic recognition for the selection of word relationships.To compile a good and easy-to- use thesaurus,we should use both computer-based automatic methods and traditional manual methods.7 tabs.10 refs. |
