The concept of Semantic Web, introduced by Berners-Lee in 2001, emphasizes importance of expressing semantics of data stored on the web. The introduced data format called Resource Description Framework (RDF) is a meaningful way of expressing and exploring data relations. It provides basics for constructing semantics-oriented data formats including ontology. More and more often ontology and RDF are used to represent variety of data including N-ary relations and temporal information. On many

The thesis introduces and describes a methodology for querying RDF-based data containing temporal information and built using non-trivial data structures. The methodology is suitable for dealing with logic-based data structuresontologyand less constrained data formats -RDF. A significant contribution of the thesis is a fuzzy-based Linguistically Oriented RDF Interface -LORI. The interface includes specialized buildin predicates suitable for constructing temporal queries and supporting imprecise phrases describing time and data features, and high-level predicates built based on them. A number of case studies focused on querying time-based events, as well as and their performance evolutions are presented. iii This thesis is dedicated to my wife, father and the memory of my mother. iv
