  abstract = {UDDI registries are included as a standard offering within the product suite of any major SOA vendor, serving as the foundation for establishing design-time and run-time SOA governance. Despite the success of the UDDI specification and its rapid uptake by the industry, the capabilities of its offered service discovery facilities are rather limited. The lack of machine-understandable semantics in the technical specifications and classification schemes used for retrieving services, prevent UDDI registries from supporting fully automated and thus truly effective service discovery. This paper presents the implementation of a semantically-enhanced registry that builds on the UDDI specification and augments its service publication and discovery facilities to overcome the aforementioned limitations. The proposed solution combines the use of SAWSDL for creating semantically annotated descriptions of service interfaces and the use of OWL-DL for modelling service capabilities and for performing matchmaking via DL reasoning.},

@inproceedings{vitvar2008wsmolite,
  abstract = {Current efforts in Semantic Web Services do not sufficiently address the industrial developments of SOA technology in regards to bottom-up modeling of services, that is, building incremental layers on top of existing service descriptions. An important step in this direction has been made in the W3C by the SAWSDL WG proposing a framework for annotating WSDL services with arbitrary semantic descriptions. We build on the SAWSDL layer and define WSMO-Lite service ontology, narrowing down the use of SAWSDL as an annotation mechanism for WSMO-Lite. Ultimately, our goal is to allow incremental steps on top of existing service descriptions, enhancing existing SOA capabilities with intelligent and automated integration.},

@inproceedings{roman2008wsmo,
  abstract = {Several approaches to semantic Web services, including OWL-S, SWSF, and WSMO, have been proposed in the literature with the aim to enable automation of various tasks related to Web services, such as discovery, contracting, enactment, monitoring, and mediation. The ability to specify processes and to reason about them is central to these initiatives. In this paper we analyze the WSMO choreography model, which is based on Abstract State Machines (ASMs), and propose a methodology for generating WSMO choreography from visual specifications. We point out the limitations of the current WSMO model and propose a faithful extension that is based on Concurrent Transaction Logic (CTR). The advantage of a CTR-based model is that it uniformly captures a number of aspects that previously required separate mechanisms or were not captured at all. These include process specification, contracting for services, service enactment, and reasoning.},

@inproceedings{lin2008service,
  abstract = {In Web Service Composition (WSC) problems, the composition process generates a solution, i.e., a composition (or a plan) of atomic  services, whose execution achieves some objectives on the Web. Existing research on Web service composition generally assumed that these objectives are absolute; i.e., the service-composition algorithms must achieve all of them in order to generate successful outcomes; otherwise, the composition process fails altogether. The most straightforward example is the use of OWL-S process models that specifically tell a composition algorithm how to achieve a functionality on the Web. However, in many WSC problems, it is also desirable to achieve users' preferences that are not absolute objectives, but a solution composition generated by a WSC algorithm must satisfy those preferences as much as possible.  In this paper, we first describe a way to augment OWL-S process models by qualitative user preferences. We achieve this by mapping a given set of process models and preferences into a planning language for representing Hierarchical Task Networks (HTNs). We then present SCUP, our new WSC algorithm that performs a best-first search over the possible HTN-style task decompositions by heuristically scoring those decompositions based on ontological reasoning over the input preferences. Finally, we discuss our theoretical and experimental results on the SCUP algorithm.},

@inproceedings{hyvönen2008building,
  abstract = {This article presents the vision and a framework for creating a national level ontology and ontology service infrastructure in Finland. Core parts of the system and ontologies have been implemented in a national project FinnONTO 2003-2007 funded by 37 companies and public organizations, and are being used it practice for creating semantic portals for eCulture, eHealth, eLearning, and eGovernment. The novelty of the FinnONTO infrastructure is based on two ideas. First, a system national of open source core ontologies is being developed by transforming thesauri in use into lightweight ontologies. The system is based an a large cross-domain top ontology, the General Finnish Ontology YSO, that is then extended by domain specific ontologies aligned with YSO and each other. Collaborative development of such a system of mutually aligned ontologies is supported for obtaining interoperability in their usage in applications. Second, the ONKI Ontology Server framework for publishing ontologies as ready to use services has been implemented. In contrast to earlier ontology servers, ONKI provides legacy and other applications with ready to use functionalities for using ontologies on the HTML level by Ajax and semantic widgets. The idea is to use ONKI for creating mash-up applications in a way analogous to using Google, Yahoo, or Nokia Maps, but in our case external applications are mashed-up with ontology support for, e.g, indexing content or semantic search using semantic autocompletion and disambiguation in a multi-lingual context.},
