In this article we describe the use of the international standard for museum ontologies, CIDOC-CRM, to build a concrete ontology for ME, a virtual museum for the Emigration phenomena. Although the digital document repository is a conventional relational database, more abstract data models should be used to enable conceptual navigation over the information to help end-users (the museum visitors) to extract knowledge from the navigation (the visit). Thus, we will emphasize the design of a Reduced CRM-compatible form to describe the objects of our assets (people that emigrate in some moment to some other country), and the relations holding among them that better express the emigration movements. We also discuss the choice of RDF to expose the ontology triples via Apache Jena Fuseki server, a SPARQL end-point accessible over HTTP, and an engine (Jena ARQ) to query the RDF data. Finally, it was possible to transform these data into RDF and apply SPARQL queries, returning the desired resu...

ABSTRACT Every year the queues in publics and privates hospitals grows due to, among others, the increasing of the world population and the delay in the patients attendance. This is a serious problem faced by administrators of hospitals whose believe that it is increasingly difficult to offer quality service to those who search for it. One of the ways to decrease these queues is through the development of homecare systems that ensure the patient to receive the clinic treatment directly in his house. These kind of systems would help to decrease the queues and consequently, would improve the attendance of those who goes to the hospitals looking for assistance. Considering this, we present in this paper the modelling of an architecture for pervasive systems to be applied in homecare environments. The pervasive systems developed from this modelling aim to improve the services provided by healthcare professionals in the treatment of patients that are located in their houses. The architecture uses concepts of pervasive computing to provide access to information anytime and wherever the user is, once a homecare environment has a high level of dynamicity of the involved. The knowledge representation of the environment needed in the modelling of the architecture is made through ontologies due to the possibility of reuse of the information stored, as well as the interoperability of information among different computational devices.

In the last years ontologies are being used in the development of pervasive computing applications. It is habitual their use for facilitating the interoperability among context-aware applications and the entities that may enter in the context at any time. This chapter presents ...
