An experimental prototype system was created and used to investigate how information relevant to analyst queries, and constrained by a contextual model, can be found over a large information space. Agents employing the ant model sift through documents quickly using a transductive support machine classifier and return those meeting a classifier which is constantly refined through feedback from semantic...
We present ISENS, a distributed, end-to-end, ontology-based information integration system. In response to a user's query, our system is capable of retrieving facts from data sources that are found in the surface semantic Web as well as inthe semantic Deep Web. Furthermore, it retrieves facts from sources where the data is not directly described in terms of the query ontology. Instead, its ontology...
In this paper, we recognize the shortcomings of the current search engines that do not index and search the deep Web. We present requirements of a deep Web service search engine, that will lead to the query objects in the deep data sources. In order to realize the DWS search engine, we propose semantic metadata and annotation of deep Web services (DWS), a reasoning component to assess the relevance...
One of the challenges in SOA is to provide an efficient and effective way to select compatible Web service(s) and compose them into a functional service process that satisfies a user's needs. Moreover, the Web services(s) selected may be integrated with structures such as branches and merges to fulfill a task. This paper describes our system architecture and strategies on Web services composition...
