The Role of Vague Categories in Semantic and Adaptive Web Interfaces

Abstract

Abstract. Current Semantic Web technologies provide a logic-based framework for the development of advanced, adaptive applications based on ontologies. But the experience in using them has shown that, in some cases, it would be convenient to extend its logic support to handle vagueness and imprecision in some way. In this paper, the role of vagueness in the description of Web user interface characteristics is addressed, from the viewpoint of the design of adaptive behaviors that are connected to such descriptions. Concretely, vague descriptions combined with quantified fuzzy rules and flexible connectors are described, and their usefulness is illustrated through preference modeling, filtering and adaptive linking scenarios.

Introducing Fuzziness in Existing Orthogonal Persistence Interfaces and Systems

“…In addition, provided that the vision of a Semantic Web (Berners-Lee, Hendler & Lassila, 2001) becomes a reality, the amount of metadata expressed in XML-based languages like RDF will call for new requirements on object models and databases, and also new query languages (Karvounarakis et al, 2003). Consequently, research on the integration of fuzziness in languages for the description of Web resources represents an important direction that has yet be addressed in a number of research works regarding fuzzy description logics -see, for example (Straccia, 2001) -and their practical application for Web management issues (Sicilia, 2003).…”
