文本对象查询的相关性计算

本文把特征文件，符号对象模型及时间戳排序等概念引入到文本对象查询系统的设计之中，提出了基于索引调组集的用户查询和文本对象相关性计算，以词组标识解决词组同义词等价性判定问题以及借助于时间戳排序技术充分利用查询反馈信息以提高系统时空效率的算法和方法，并讨论了面向文本数据库管理系统的文本对象查询的优化策略及逻辑实现等问题。

RELEVANCE CALCULATION OF TEXT OBJECT QUERY

In this paper,we introduce the concepts of signature file,symbolic object model and timestamp ordering into the design of text object query system,and put forward some algorithms and methods, which can be used to calculate the relevance between a user query and a text object based on indexing vocabulary set and to solve the decision problem of synonym equivalentce by the word identification and to enhance the system efficiency in time and space using relevance feedback data that has been collected from a set of queries by the techniques of timestamp ordeing. we end the paper by considering the optimization tactics and the logical implementation of text object query in the text-oriented database management system (FIMS).
