Interactive Exploration of Fuzzy RDF Knowledge Bases

Presented at: 8th Extended Semantic Web Conference (ESWC2011)

by Nikos Manolis, Yannis Tzitzikas

There are several applications that provide access to objects whose descriptions are accompanied by a degree expressing their strength. Such degrees can have various application specific semantics, such as relevance, precision, certainty, trust, etc. In this paper we consider Fuzzy RDF as the representation framework for such "weighted" descriptions, and we propose a novel model for interactively browsing and exploring such sources which allows formulating complex queries by simple clicks. Specifically, and in order to exploit the fuzzy degrees, the model proposes interval-based transition markers. The advantage of the model is that it significantly increases the discrimination power of the interaction, without making it complex for the end user.
