Querying RDF Data with Imprecise Time Phrases

Semantic Web is an important step towards significant changes in representation and utilization of data on the web. The use of Resource Description Framework (RDF) as a fundamental data format creates new ways of expressing and exploring relations existing between pieces of data. An importance of articulating temporal aspects using RDF data, and a need to query these data using vague and imprecise terms is a challenging undertaking. This paper presents a fuzzy-based approach to deal with RDF data containing temporal information and built using non-trivial data structures (RDF Schemas). It includes description of built-in predicates needed for constructing temporal queries and supporting imprecise phrases describing time and data features. A simple case study using DBLP database illustrates the application of the proposed approach.
