摘要

短语浏览技术使用从大量信息集合中自动提取的短语作为浏览和访问的基础。本文描述了一个使用自动构建的短语层次结构来促进普通大型网站浏览的案例研究。短语是从全文中提取使用基本的句法处理和顺序语法归纳技术的新颖组合。界面简单,健壮,易于使用。为了传达对自动生成的短语质量的感觉,研究了负责Web站点的组织使用的同义词典,并分析了它与层次结构中的短语的重叠程度。我们的最终目标是合并分层短语浏览和分层同义词典浏览:后者提供了一个权威的领域词汇表,而前者增加了同义词典没有达到的区域的覆盖范围。

Scalable browsing for large collections: a case study
Phrase browsing techniques use phrases extracted automatically from a large information collection as a basis for browsing and accessing it. This paper describes a case study that uses an automatically constructed phrase hierarchy to facilitate browsing of an ordinary large Web site. Phrases are extracted from the full text using a novel combination of rudimentary syntactic processing and sequential grammar induction techniques. The interface is simple, robust and easy to use. To convey a feeling for the quality of the phrases that are generated automatically, a thesaurus used by the organization responsible for the Web site is studied and its degree of overlap with the phrases in the hierarchy is analyzed. Our ultimate goal is to amalgamate hierarchical phrase browsing and hierarchical thesaurus browsing: the latter provides an authoritative domain vocabulary and the former augments coverage in areas the thesaurus does not reach.
