[Show abstract][Hide abstract] ABSTRACT: This paper is a preliminary report on the development of a "declarative" programming language SPL+. It assists non-technical people to write programs. The key idea behind SPL+ is that the "programmer" only needs to solve target problems with a standardized methodology without worrying about how to solve the problem efficiently.
[Show abstract][Hide abstract] ABSTRACT: With the increasing development of web service technologies, more and more applications need web services to give strong capabilities. We divide the existing information space into two levels - semantic space and information space. It will make the tranditional operations on web services been abstracted from information space level into semantic space level. Through semantic computing and semantic reasoning, it is more effective to implement the service discovering, searching , and composing etc. We give a semantic resource description framework RDF4S and its description document WSDL4S for semantic web service. This paper presents an approach to establish semantic information space model based on WSDL4S document using data mining technologies and ontology technologies. The method constructs a mapping between general information space and semantic information space. A specific case is given to prove the validity of this method at the end of the paper.
