中文简介:
本文提出了一个实现查询细化方法的正式框架。该方法使用面部分析的一般原理。提出并讨论了两个关键概念:多样性和重点。多样性是指查询用户的信息需求;它被'facet'的概念所捕获。重点是指如何从用户组织的文档中捕获多样性;它为用户查询提供了一种上下文。该方法位于最小命题闭合描述逻辑ALC的形式框架内,从而打赌ALC为我们提供了合适的SAT求解器来实现方面引擎,这是我们方法的主要组成部分。
课程简介: This paper presents a formal framework for implementing a query refinement method. The method uses general principles of facet analysis. Two key notions are advanced and discussed: diversity and focus. Diversity refers to the information needs of a querying user; it is captured by the notion of ‘facet’. A focus refers to how diversity is captured from the documents as organized by the user; it provides a kind of context to the user query. The method is situated within the formal framework of the smallest propositionally closed description logic ALC, thereby betting that ALC provides us with a suitable SAT solver to implement a facet engine, which is the main component of our method.
关 键 词: 面部分析; 多样性; 查询细化
