Previous issue date: 2007-12-28 === 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 propose the construction of web services and ontologies
altogether so that the arguments and results of a web service correspond to instances and
properties of the ontology associated with that web service. We define the concept of
Active Ontologies, i.e. ontologies that have mechanisms (web services associated with
them) that insert and delete, dynamically and temporarily, individuals and property
values in their specification. In the specific case of ontologies modeled in OWL, it is
presented an implementation of the Active Ontologies concept called Active OWL. In
Active OWL, classes and properties are annotated by linking them with web services that
are responsible for retrieving, inserting, and retracting individuals from the given
ontology. === Diversas propostas têm sido feitas para especificar semântica de serviços web existentes. Um traço comum destas propostas é que tentam especificar a semântica de serviços web construídos a priori utilizando ontologias que também já existem a priori. Neste trabalho propomos a construção de ontologias e serviços web conjuntamente de forma que os argumentos e resultado dos serviços web correspondam a instâncias e propriedades da ontologia a ele associado. Definimos assim o conceito de ontologias ativas, i.e. ontologias que possuem mecanismos (serviços web a ela associados) que permitem incluir e excluir, dinâmica e temporariamente, indivíduos e valores de propriedades em sua especificação. Para o caso particular de ontologias expressas em OWL apresentamos uma implementação do conceito de ontologias ativas, chamado de Active OWL. Em Active OWL classes e propriedades são anotadas indicando serviços web responsáveis por recuperar, inserir, retirar indivíduos na ontologia. |
