In this paper, I present issues related to user profiles and their management in pervasive computing. I motivate the need for user profiles and present basic techniques that can be used in storing and managing profiles. I also present technigues that can be used to help profiling and Semantic Web techniques that are also emerging to help also in problems associated with user profiling and intelligent applications.

RosettaNet is an industry-driven e-business process standard that defines common inter-company public processes and their associated business documents. RosettaNet is based on the Service-oriented architecture (SOA) paradigm and all business documents are expressed in DTD or XML Schema. Our “ontologically-enhanced RosettaNet” effort translates RosettaNet business documents into a Web ontology language, allowing business reasoning based on RosettaNet message exchanges. This chapter describes our extension to RosettaNet and shows how it can be used in business integrations for better interoperability. The usage of a Web ontology language in RosettaNet collaborations can help accommodate partner heterogeneity in the setup phase and can ease the back-end integration, enabling for example more competition in the purchasing processes. It provides also a building block to adopt a semantic SOA with richer discovery, selection and composition capabilities.

This paper presents a methodology to derive a Supply Chain Management Ontology based on the RosettaNet speciflca- tion framework. A prototype to mechanically derive a core ontology spanning all new Partner Interface Processes in the RosettaNet framework is developed and its algorithms to reconcile the ontology structure and to generate a proper subsumption hierarchy are presented. We further present how we designed and referenced outer layer ontologies we analysed to be required to resolve the remaining disparities in the core ontology. The resulting ontology framework en- ables to more easily deal with difierent message structures in dynamic Business-to-Business collaborations and thus en- sures a better interoperability for the partners involved.

In service oriented computing (SOC), applications are constructed by composing existing services. Not all compositions, however, are correct or meaningful. For example, an application needs to follow steps in a process in a meaningful order. We study feasibility of using product configuration technology in the composition of an application based on services. On the one hand, product configuration introduces a means and tools for specifying rules and structure upon which correct applications are composed in SOC. On the other hand, product configuration provides a means and tools for deriving correct applications in SOC. In the study, we apply Kumbang product configuration conceptualization for software product families. The results are demonstrated modeling as services a real case example of networked PDM system and deriving different service compositions.

Modeling the semantics of business services and their corresponding messages using ontologies enables flexible integration that is more adaptive to business-driven change. In this paper we demonstrate our approach building upon an established semantic Web service framework (WSMX) to facilitate a conversation between heterogeneous services that support both the RosettaNet standard and proprietary information models.

We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogenei- ties in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and rules to resolve data heterogeneities and to unify unit conversions. We use adaptive executable choreography definitions to eas- ily integrate new sellers into existing RosettaNet collabora- tions.

In this paper we present a B2B integration scenario building on the principles of Semantic Web services. For this scenario we show the benefits of semantic descriptions used within the integration process to enable conversation between systems with data and process mediation of services. We illustrate our approach on the WSMX – a middleware platform built specifically to enact semantic service oriented architectures.KeywordsCustomer Relationship ManagementCommunication ManagerMoon SystemPurchase OrderAbstract State MachineThese keywords were added by machine and not by the authors.

External business processes (choreography models) are currently disconnected from internal processes (workflow models), which leads to synchronisation and verification problems. Connecting these by directly mapping internal to external processes requires a quadratic amount of mappings; an intermediate ontology reduces the amount of necessary mappings but is not trivial to construct due to the variety in workflow meta-models. We introduce our multi meta-model process ontology (m3po) which is based on various existing reference models and languages from the workflow and choreography domain. The m3po ontology relates workflow models to choreography models and allows choreography extraction from internal workflow models. An initial validation is given by translating an IBM Websphere MQ workflow model into the m3po ontology and subsequently extracting an abstract BPEL model from the ontology
