基于刻面的藏/汉教育资源的检索设计与实现

Tibetan/Chinese education resources retrieval design and implementation based on facets

通过反映教学资源本质特性的视角采用刻面技术对所要描述的资源进行精确地描述、表示、分类。一个刻面分类模式由一组描述资源本质特性(刻面术语)的刻面组成,从而构建出每个教学资源的描述树或查询匹配树。用户通过提供关键词(术语)形成查询条件,构成一棵刻面查询树,通过相应的匹配算法将描述树和匹配树进行比较,根据返回的i值的大小,找出近似匹配教学资源集有序地呈现给用户。

This paper reflects the essential characteristics of teaching resources,and then makes an accurate description,indication and classification to the resources need to be described.A facet classification model is composed by a set of facets which used to describe resource characteristic（facets term）,so as to build the describe tree and query matching tree to each teaching resource.Users can form the query condition by providing key words （terms）,and constitute a facet query tree.Through the respondent matching algorithm,the comparison between describe tree and matching tree is made.According to the size of returned value i,the approximate matching teaching resources can be found out and presented to the users.
