摘要

本文提出了部分匹配模式的XML文本文档向量检索模型

给出了XML文本文档树以及子文档树的向量表示和查询以及子查询的向量表示

并由此提出了查询中的祖先-后代关系映射到文档中的祖先-后代关系的部分匹配模式的检索方式

给出了基于此匹配处理过程的相似度计算

以判断文档与查询的相关程度.在构造的检索原型系统中的实验表明

该检索模型具有较好的查全率和查准率.

Abstract

This paper presents the vector retrieval modeling using the partial match pattern for text-rich YML documents. The vector representation of the tree of text-rich XML documents and sub-documents and the tree of queries and sub-queries are decribed. The partial match pattern is mapping from the relations of ancestors and descendants for a query to the relations of ancestors and descendants for documents.The paper calculates the similarity in the processing of the partial match.The results of experiemental analyses with different collections and queries show that it is effective in the completeness search and the precision search.
