Comparison of Time Concept Modeling for Querying Temporal Information in OWL and RDF

Abstract

Abstract-Ontology is an important factor in the integration of heterogeneous semantic information. Description logic, as a formal language for expressing ontologies, does not include the necessary features to create a temporal dimension in the relationships among concepts. It is critical to introduce time concepts to model temporal data and relate them to other non-temporal data recorded in ontology. Current query languages in the semantic web are not able to respond to temporal questions; thus, another important issue is to have the appropriate methods for answering temporal questions. In this paper, temporal modeling methods in OWL and RDF are assessed and the temporal query languages for expressing queries in the semantic web are categorized and compared.Index Terms-Ontology, temporal model, description logic, temporal query language.

Engineering uncertain time for its practical integration in ontologies

“…As one of the results of these limitations, the literature does not present examples of real case applications of these approaches, but only restricted studies based on temporal language queries, such as TOQL and SQWRL, as demonstrated by Bahadorani and Zaeri [29]. Section 4 lists the requirements of our approach aimed at covering these limitations.…”

Decision Support System to Determine Promotional Methods and Targets with K-Means Clustering

“…Numerous applications and ontologies have been developed based on the temporal models with the objectives of incorporating time into RDF and OWL structures. After defining time, is understanding and knowing how to process the stored information based on temporal models and then selecting an appropriate language to query and extract new knowledge from the knowledge base [12].…”
