In this paper, we present an approach to hybrid semantic Web service selection of semantic services in SAWSDL based on logicbased matching as well as text retrieval strategies. We discuss the principles of semantic Web service description in SAWSDL and selected problems for service matching implied by its specification. Based on the result of this discussion, we present different variants of hy...

\Semantic uni cation" is the process of generating a basis set of substitutions (of terms for variables) that makes two given terms equal in a speci ed theory. Semantic uni cation is an important component of some theorem provers. \Semantic matching," a simpler variant of uni cation, where the substitution is made in only one of the terms, has potential usage in programming language interpreter...

The left angular gyrus (AG) is reliably activated across a wide range of semantic tasks, and is also a consistently reported component of the so-called default network that it is deactivated during all goal-directed tasks. We show here that there is only partial overlap between the semantic system and the default network in left AG and the overlap defines a reliable functional landmark that can...

Ontologies are increasingly being used to address the problems of heterogeneous data sources. This has in turn often led to the challenge of heterogeneity between ontologies themselves. Semantic Matching has been seen as a potential solution to resolving ambiguities between ontologies . Whilst generic algorithms have proved successful in fields with little domain specific terminology, they have...

We think of Match as an operator which takes two graph-like structures (e.g., conceptual hierarchies or ontologies) and produces a mapping between those nodes of the two graphs that correspond semantically to each other. Semantic matching is a novel approach where semantic correspondences are discovered by computing, and returning as a result, the semantic information implicitly or explicitly c...

Web services are the latest attempt to revolutionize large scale distributed computing. They are based on standards which operate at the syntactic level and lack semantic representation capabilities. Semantics provide better qualitative and scalable solutions to the areas of service interoperation, service discovery, service composition, and process orchestration. SAWSDL defines a mechanism to ...

What is the relative salience of different aspects of word meaning in the developing lexicon? The current study examines the time-course of retrieval of semantic and color knowledge associated with words during toddler word recognition: At what point do toddlers orient toward an image of a yellow cup upon hearing color-matching words such as "banana" (typically yellow) relative to unrelated wor...

Please cite this article in press as: Liu, M., et al. A (2009), doi:10.1016/j.eswa.2009.04.034 A critical step in the process of reusing existing WSDL-specified services for building web-based applications is the discovery of potentially relevant services. However, the category-based service discovery, such as UDDI, is clearly insufficient. Semantic web services, augmenting web service descript...

A Multi-matching Technique for Combining Similarity Measures in Ontology Integration Ahmed Khalifa Alasoud, Ph.D. Concordia University, 2009 Ontology matching is a challenging problem in many applications, and is a major issue for interoperability in information systems. It aims to find semantic correspondences between a pair of input ontologies, which remains a labor intensive and expensive ta...

String matching has been widely used in more and more web data applications. Although a lot of matching techniques have been proposed, most of them are based on evaluating the similarity of strings in terms of their lexical or syntactic structures. The fact is that the same entity can be denoted by totally different expressions for which the conventional syntactic-based string matching techniqu...
