基于布尔逻辑的文本查询语言在在线信息库的搜索工具中是常见的。然而，有证据表明，这些语言的句法和语义要求导致用户错误，并对用户形成查询所需的时间产生不利影响。此外，用户面临的用户界面，这些知识库是无响应和无信息，因此无法支持有效的查询细化。我们建议，图形查询语言，特别是文氏图，提供了一个自然的媒介，布尔查询规范，克服了文本查询语言的问题。此外，动态结果预览可以与图形查询规范无缝集成，以提高查询细化的有效性。我们描述VQuery，查询接口，新西兰数字图书馆，利用查询维恩图和综合查询结果预览。
Textual query languages based on Boolean logic are common amongst the search facilities of on-line information repositories. However, there is evidence to suggest that the syntactic and semantic demands of such languages lead to user errors and adversely affect the time that it takes users to form queries. Additionally, users are faced with user interfaces to these repositories which are unresponsive and uninformative, and consequently fail to support effective query refinement. We suggest that graphical query languages, particularly Venn-like diagrams, provide a natural medium for Boolean query specification which overcomes the problems of textual query languages. Also, dynamic result previews can be seamlessly integrated with graphical query specification to increase the effectiveness of query refinements. We describe VQuery, a query interface to the New Zealand Digital Library which exploits querying by Venn diagrams and integrated query result previews.
