Semantic descriptions provide more accurate information related to operations supported by Web services, enabling their dynamic discovery and execution without human intervention. Furthermore, semantic descriptions allow Web services to be automatically combined by using discovery mechanisms able to identify composed services. These compositions can also be described and published as if they we...

this research titeled (semantic change in the quranic words: praise prophet reverence) this study is about how to transform from the meaning to another. in this article we looked lexical and semantic meaning of three words of quran in pre-islamic era until the end of sending quran. we studied the influence of islam in changing word semantically. islam does not bring new words but added them new...

In the paper new logics oriented on hierarchical data are developed. Algebras of partial predicates over such data with special compositions as operations form a semantic base for constructed logics. Characteristic property of such logics is the usage of composite names in their languages. Semantic properties of these logics are studied; corresponding sequent calculi are defined, their soundnes...

Semantic web services represent an important and actual research area in computer science. A very popular topic in this area is the composition of semantic web services, which can be used for obtaining new semantic web services from existing ones. Based on a representation method for the semantic descriptions of semantic web services, that we had previously proposed, we propose a multi-agent sy...

Ranking and optimization of web service compositions are some of the most interesting challenges at present. Since web services can be enhanced with formal semantic descriptions, forming the ”semantic web services”, it becomes conceivable to exploit the quality of semantic links between services (of any composition) as one of the optimization criteria. For this we propose to use the semantic si...

This paper describes an application of semantics to sensors to automatically create sensor compositions. Two main contributions of this paper are a sensor ontology and a composition system. The OWL ontology describes user goals, functional and non-functional properties of sensors and sensor composition, while the Region Connection Calculus and Allen’s Interval Algebra are used for describing th...

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...
