| 中文摘要: |
| 传统的基于关键词的信息检索不能理解用户的需要，仅仅对关键词进行简单的匹配，其结果往往包含大量与用户实际需要毫不相干的信息，同时却丢失用户实际需要的信息，使得检索的效率很低.基于本体的语义检索技术的出现，弥补了基于关键词检索的不足，成为目前构建信息检索系统的应用热点.本文主要针对燃气管网的材料腐蚀信息，设计一个基于GIS（Geography Information System）的管网材料腐蚀信息语义检索系统，使用户检索管网空间数据和腐蚀数据时为其提供相关数据的语义信息，同时也使得检索结果更加符合用户需求. |
| 英文摘要: |
| Traditional keywords retrieval didn’t understand the requirement of users,which is a process of simple matching.The results of keywords retrieval usually include much needless information,meanwhile,some information the user needs are neglected.To make up for the deficiency of keywords retrieval,semantic retrieval is proposed,which is a hotspot in the application of building information retrieval system.Taking the materials corrosion information of Gas Network as example,this paper introduces a semantic retrieval system based on GIS to search the material corrosion information of pipeline network.The aim of this system is to provide more semantic information about spatial data and corrosion data of pipeline network.Moreover,the results of semantic retrieval could meet the extensible needs of users. |
