Triple Space Computing is a communication and coordination paradigm that allows communication of semantic technologies in general, by publish and read of semantic data. It has also been provided as an underline communication middleware for Semantic Web Services. While focusing on scalability and openness of Triple Space Computing to bring it into its full potential in a global view, the possibility of heterogeneity among different users communicating over Triple Space is very likely to arise. This paper focuses on providing the Triple Space Computing with data mediation to enable easy integration of data, information, and knowledge. Mediation is a technique to overcome heterogeneity issues in a system, i.e. to remove differences in the syntactic representation and the intended semantics of data that is exchanged [2]. The paper introduces an Abstract Mapping Language and shows how mapping rules can be created using this mapping language. It further proposes mediation APIs for users and internal system. It also explains the grounding of mediation mapping rules to Triple Space. It further provides a refined version of architecture of the mediation engine along with its bindings with other components of Triple Space Computing paradigm.
Corporate portals, such as the one used by the Telefónica group, make an important integral part of the enterprise infrastructure, facilitating the creation, sharing, discovery and consumption of enterprise assets through blogs, news, forums, documents and information in general. However, as the amount of data grows, it becomes much more difficult to access the right asset in the precise moment when it is needed. Annotation systems try to address this problem to a certain extent by allowing the users to collaboratively annotate assets using tags so they can be found more easily by reusing these tags in queries. However, this model often falls short due to mismatches in the vocabularies of different users who use synonymous, polysemous, or more specific (or general) terms in tagging and searching. In this paper we: (a) provide a description of the corporate portal of the Telefónica group; (b) define a semantic annotation model that was developed to address the above-mentioned problems; (c) provide details of the implementation of the annotation model for the Telefónica portal; and (d) report the results of an initial evaluation of a concept-based search enabled by the model.
A Multimedia Content Marketplace can support innovative business models in the telecommunication sector. This marketplace has a strong need for semantics, coordination and a service-oriented architecture. Triple Space Computing is an emerging semantic coordination paradigm for Web services, for which the marketplace is an ideal implementation scenario. This paper introduces the developed Triple Space platform and our planned evaluation of its value to our telecommunication scenario.
Businesses need to "reduce costs" and improve their "time-to-market" to compete in a better position. Systems must contribute to these two goals through good designs and technologies that give them agility and flexibility towards change. Semantics and Data Mining are two key pillars to evolve the current legacy systems towards smarter systems that adapt to changes better. In this article we present some solutions to evolve the existing systems, where the end user has the possibility of modifying the functioning of the systems incorporating new business rules in a Knowledge Base.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
