Concept Expansion Using Semantic Fisheye Views

Abstract

Abstract.Exploratory search over a collection often requires users to iteratively apply a variety of strategies, such as searching for more general or more specific concepts in reaction to the information they encounter. Rich semantic models, such as WordNet, are potentially valuable aids for making sense of this information. However, these large complex models often contain specialized vocabularies and a detailed level of granularity that makes them difficult to use for opportunistic search. In this paper, we describe how Semantic Fisheye Views (SFEV) can be designed to transparently integrate rich semantic models into the search process, allowing users to effectively explore a diverse range of related concepts without explicitly navigating over the underlying model. The SFEV combines semantic guided search with interactive visualization techniques, creating a search tool that we have found to be significantly more effective for exploratory tasks than those based on keyword-similarity alone.

Metadata-enhanced visual interfaces to digital libraries

“…They used interactive dynamic maps to represent the semantic content of the thesaurus and the document collection. Janecek et al [16,17] have developed a visual interface for digital collections using fisheye views. The WordNet semantic structure is incorporated into the interface to support users' exploratory search experience.…”
