The semantic Web Services vision requires that each service be annotated with semantic metadata. Various metadata languages (such as OWL-S (DAML-S Coalition 2003)) have been proposed to fill this “semantic gap”. However, manually creating such metadata is tedious and error-prone. Software engineers, accustomed to tools that automatically generate WSDL, might not want to invest the required effo...

Semantic web provides virtual communities that enable intelligent interaction between software agents and people due to availability of standard open ontologies. But, as the semantic web is gaining much popularity, there is a massive growth seen in the ontology development which poses new research challenges such as ontology classification, ranking, searching, retrieval, etc. This results many ...

To respond appropriately to objects, we must process visual inputs rapidly and assign them meaning. This involves highly dynamic, interactive neural processes through which information accumulates and cognitive operations are resolved across multiple time scales. However, there is currently no model of object recognition which provides an integrated account of how visual and semantic informatio...

The massive growth in ontology development has opened new research challenges such as ontology management, search and retrieval for the entire semantic web community. These results in many recent developments, like OntoKhoj, Swoogle, OntoSearch2, that facilitate tasks user have to perform. These semantic web portals mainly treat ontologies as plain texts and use the traditional text classificat...

This paper discusses some issues associated with systems evolution in a decentralised organisation. The divisions of the particular organisation are functionally very similar but territorially decentralised and managerially autonomous. The paper considers the real case of an engineering fault logging system which has different versions in use by the different divisions of the organisation. It r...

Content-based image indexing and retrieval have become important research problems with the use of large databases in a wide range of areas. In this study, a content-based image retrieval system that is based on scene classification for image indexing is proposed. Instead of using low-level features directly, semantic class information that is obtained as a result of scene classification is use...

Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and...
