  <description><![CDATA[CREDO is a context aware architecture  which is built on a subscription based paradigm. Credo supports both SIP (session initiation protocol) as well as HTTP. This system compromises of Context providers and Context Consumers, the consumers need to discover these services and subscribe to them giving restriction on when they should be notified.We modeled these services using OWL-S and extended OWL-S to allow subscription with restriction specified in SWRL or Joshua Rules.
We also added a SIP...]]></description>

  <description><![CDATA[Though the description of capabilities and constraints for web services is an important problem, we believe that is it part of a much larger problem : controlling the behavior of autonomous entities in
open, dynamic environments. This problem deals with not only with the specification of attributes (i.e. privacy restrictions, access control
rules, communication requirements) that will enable interacting entities to behave appropriately, but also with the specification of all aspects of th...]]></description>

  <description><![CDATA[The ultimate goal of service matching is to find the service provider(s) that can perform tasks of a given description with the best overall degree of satisfaction. However, service description matching solves only part of the problem. Agents that match a given service request description may vary greatly in the level and/or quality of services that they can perform, and an agent may have strong and weak areas in its advertised service space. In this work, we take a quantitative approach in w...]]></description>

  <description><![CDATA[Web Services will soon handle users’ private information. They’ll need to provide privacy guarantees to prevent this delicate information from ending up in the wrong hands. More generally, Web Services will need to reason about their users’ policies that specify who can access private information and under what conditions. We propose a more fine-grained security markup of service parameters in OWL-S.  We extend our previous work with annotations about the security and privacy policies o...]]></description>

  <description><![CDATA[In this paper, we address the security of semantic Web services that are declaratively described in OWL-S. We propose ontologies to annotate OWL-S input and output parameters with respect to their security characteristics, including encryption and digital signatures. Moreover, we propose to incorporate privacy and authentication policies into OWL-S descriptions and requester profiles.  We designed and implemented algorithms to check policy compliance and integrated them into the service selec...]]></description>
