This paper describes a semantic extension to the Mathematical Services Query Language (MSQL). MSQL is a language for querying registry-published mathematical Web service descriptions expressed in the Mathematical Services Description Language (MSDL). The semantic extension allows queries in MSQL to be based on the underlying semantics of service descriptions; the MSQL engine processes these que...

this paper provides a novel semi-automatic ontology extension method for Semantic Web Services (SWS). This is significant since ontology extension methods those existing in literature mostly deal with semantic description of static Web resources such as text documents. Hence, there is a need for methods that can serve dynamic Web resources such as SWS. The developed method in this paper avoids ...

This paper introduces a novel wrapper-mediator based semantic data grid service mechanism to solve the problem of Semantic heterogeneity and few compatible data sources. It uses ontology based semantic information to wrap the heterogeneous data source, and employs mediator structure to supply accessing interface for the data sources, and it extends semantic query, mapping and fusion languages t...

The need for fuzzy knowledge bases arises from many application fields, such as trust management. To represent fuzzy data, a syntactic and semantic extension of RDF is proposed. The syntax adds to each triple a truth value. The semantic for Fuzzy RDF and Fuzzy RDF Schema allows to derive truth values for derived statements as well. Fuzzy RDF/RDFS does not aim to become a standard extension to p...

This paper proposes an extension to the Hermes Framework, allowing the user to create advanced graphical queries. Hermes is a Web-based framework designed to build personalized news services using Semantic Web technologies. It makes use of ontologies for knowledge representation, natural language processing techniques for semantic text analysis and semantic query languages for specifying the de...

Current conceptual models and methodologies for Web applications concentrate on content, navigation, and service modeling. Although some of them are meant to address semantic web applications too, they do not fully exploit the whole potential deriving from interaction with ontological data sources and and from Semantic annotations. This paper proposes an extension to Web application conceptual ...

Complex relationships, frequently referred to as semantic associations, are the essence of the Semantic Web. Query and retrieval of semantic associations has been an important task in many analytical and scientific activities, such as detecting money laundering and querying for metabolic pathways in biochemistry. We believe that support for semantic path queries should be an integral component ...

[8] merges the semantic frameworks of Dynamic Epistemic Logic DEL ([1, 3]) and Epistemic Temporal Logic ETL ([2, 6]). We consider the logic TDEL on the merged semantic framework and its extension with the labeled past-operator “P!” (“The event ! has happened before which...”). To axiomatize the extension, we introduce a method to transform a given model into a normal form in a suitable sense. T...
