Focused crawlers selectively retrieve Web documents that are relevant to a predefined set of topics. To intelligently make predictions and decisions about relevant URLs and web pages, different topic models have been introduced to represent topic-specific knowledge. Yet it is difficult to support semantic interoperability among different models. Moreover, some manually specified additional semantic...
This paper presents a dynamic description logic and a sound and complete tableau-based satisfiability-checking algorithm for it. This logic is a combination of a typical action theory and the description logic ALCO@, with a feature that actions are treated as citizens. On the one hand, actions are represented over ontologies expressed in description logic; On the other hand, actions can be used as...
Web services composition techniques are gaining momentum as the opportunity to establish reusable and versatile inter-operability applications. The purpose of semantic Web services is to use semantic specification to automate the discovery, invocation, and composition Web services. Description logics is the formalized foundation of semantic Web services and provides well-defined semantics. And many...
