In open networked systems, each node shares part of its informational resources on the network and is responsible of providing an ontological description for them. To enable semantic information interoperability in networked contexts with a multitude of autonomous ontologies, appropriate matching techniques are required to determine semantic mappings between concepts of different ontologies. In...

This paper presents the alignment results of Lily for the ontology alignment contest OAEI 2009. Lily is an ontology mapping system, and it has four functions: generic ontology matching, large scale ontology matching, semantic ontology matching and mapping debugging. In OAEI 2009, Lily submited the results for four alignment tasks: benchmark, anatomy, directory and conference. 1 Presentation of ...

The semantic annotation of images can benefit from representations of useful concepts and the links between them as ontologies. Recently, several multimedia ontologies have been proposed in the literature as suitable knowledge models to bridge the well known semantic gap between low level features of image content and its high level conceptual meaning. Nevertheless, these multimedia ontologies ...

Patients with Alzheimer's disease (AD) were asked to name pictures and perform a multiplechoice word-picture matching task with verbs and nouns. AD patients were significantly more impaired with verbs than nouns for both naming and word-picture matching, and their patterns of semantic naming errors differed for verbs and nouns. One subgroup of AD patients was compromised on both naming and word...

The rapid growth of heterogeneous sources of massive ontology instances raises a scalability issue in ontology instance matching of semantic knowledge bases. In this paper, we propose an efficient method of instance matching by considering secondary classification of monotonic large instances to achieve scalability. We use a taxonomy of the ACM’s Computing Classification System (CCS) for second...

Semantic matching is finding a mapping between two knowledge representations encoded using the same ontology. Solving this matching problem is hard because the syntactic form of two knowledge representations rarely matches exactly. Previous research has shown transformation rules can be used to improve matching, but acquiring transformations is difficult. In this paper, we present an algorithm ...

The rapid development of semantic web services has led to a demand for a semantic web service discovery mechanism. Though such discovery systems have been developed, there is a lack of support for matching semantic web services which use different ontologies. This paper introduces a general framework for the discovery of web services that use both the same ontology as well as different ontologi...

In this paper, we describe the first hybrid semantic Web service matchmaker for OWL-S services, called OWLSMX. It complements crisp logic-based semantic matching of OWL-S services with token-based syntactic similarity measurements in case the former fails. The results of the experimental evaluation of OWLS-MX provide strong evidence for the claim that logic-based semantic matching of OWL-S serv...

One of the challenging problems that Web service technology faces is the ability to effectively discover services based on their capabilities. An approach is proposed to tackle this problem in the context of description logics. The semantic information of a Web service can be described with three factors: functional capabilities, action and non-functional attributes. We formalize these three fa...
