Several proposals have been made to specify semantics to existing web services. A common approach in these proposals is that they try to specify the semantics of web services that were built a priori by making use of ontologies that were also specified a priori. In this work, we ...

Fourth Generation Networks (4G) introduce the capability of ubiquitous access to services in heterogeneous networks. In these environments, the distribution of the management would require semantics for common sharing vocabulary, an ability which is not yet provided. For that rea...

Nowadays the interest for the theme ontologies has steadily increased, as it aims at to capture consensual knowledge between people and applications, allowing reusing and sharing information. With this purpose, mechanisms are demanded to guarantee semantic interoperability, that ...

Ontologies are becoming an important mechanism to build information systems. Nevertheless, there is still no systematic approach to support the design of such systems using tools that are common to information systems developers. In this paper, we propose an approach for deriving...

While ontology is still a fertile area of research in the field of Philosophy, Ontologies currently stands for research, development, and application fields in disciplines related with computing, information and knowledge. Information Systems (IS) are essentially knowledge artifa...

The adoption of ontologically well founded languages for building ontologies has acquiring more adopters, however its widespread use stumble on using difficulties by inexperienced modelers. This dissertation proposes a methodological guide to support the building of domain ontolo...

By combining ontologies from different sources the authors developed a novel approach to describing phenotypes of mutant mice in a standard, structured manner....

Investigates theoretical and practical interfaces between terminology, philosophical ontology, computational ontology and documentary linguistics and the subsidies that they offer for the construction of documentary information. It was established as specific objectives, the anal...

This dissertation presents an approach to the software development in the Ubiquitous Computing, which instantiates the Rational Unified Process (RUP), based on Ontologies, Semantic Web Services, and Software Agents. Ontologies are employed to improve the description of the use co...

Ontologies are complex artifacts. They should seek consensus on the use of a set of modeled concepts. Some authors propose that these devices would be beneficial if they were built collaboratively. This article aims to address the use of a semantic wiki as an alternative to the c...

Geographic Information System (GIS) are computational tools used to capture, store, consult, manipulate, analyze and print geo-referenced data. A GIS is a multi-disciplinary system that can be used by different communities of users, each one having their own interest and knowledg...

The recent developments related to knowledge management, the semantic web and the exchange of electronic information through the use of agents have increased the need for ontologies to describe, in a formal way, shared understanding of a given domain. For computers and people to ...

OntoBlast allows one to find information about potential functions of proteins by presenting a weighted list of ontology entries associated with similar sequences from completely sequenced genomes identified in a BLAST search. It combines, in a single analysis step, the search fo...

Information technology (IT) is becoming essential for organizations. In this context, IT management has evolved to include service management and IT governance, towards business driven IT management paradigms. Thus, the alignment between IT and business has been regarded as one o...

The Semantic Web (WS) is be coming an important research topic in Computer Science. One of reasons is the possibility of representing information in semantic way using ontologies, assisting in the building of applications which are able to use data, be coming more scalable and in...

Semantic portals are characterized for storing and structuring content according to specific domain ontologies. This content is represented through ontological languages, which enable not only adding semantic value to information treatment, but also inferring new knowledge from i...

The use of virtual environments, created by the computer, provides the execution of training simulations in a safe environment to investigate human behaviour and response to dangerous situations. However, building generic virtual environment simulations is a challenge to be resea...

This dissertation presents how a model driven development architecture and environment framework to support Web application development are being developed using SHDM/OOHDM as development methods. The models are described through graphical diagrams that are processed by the envir...
