摘要
En 中文
Automatic faceted navigation provides a set of navigation operations for users to browse one text or more texts from different facets of content without any input. One sentence or a sequence of sentences on a relatively independent and complete content in text constitutes a semantic unit. Semantic units on one topic may be in different locations and there are distances between semantic units. A semantic facet is a set of semantically close semantic units representing one aspect meaning of a text. This paper proposes a faceted navigation mechanism that can extract semantic units from texts, build a hierarchy of semantic facets, and navigate the hierarchy, so that users can obtain interested contents from text and navigate among semantic facets without any prior input. The proposed mechanism goes beyond cyberspace by considering the human reading processes. Experiments show the effectiveness of the proposed mechanism. (C) 2012 Elsevier B.V. All rights reserved.
