Chapter 9 documents the implementation of the core release (CREL) features of the design, namely: 1. The IT2Rail rdf-framework foundation framework for processing data expressed in the Resource Descriptor Framework (RDF) language, semantically annotated with terms described in the domain’s ontology, the latter written in the Ontology Web Language (OWL). The framework provides additionally connectivity to distributed triple stores, including the IT2Rail triple store that implements the Ontology Repository, containing the OWL ontology, and the Semantic Web Service Registry containing service descriptors also represented as RDF statements. 2. The Semantic Graph Manager component of the design, based on the IT2Rail rdf framework, which provides semantic data discovery, query an aggregation over linked, distributed triple stores. 3. The Location Resolver service of the design, which uses the Semantic Graph Manager to provide “packaged” data discovery, query and aggregation about transport “infrastructures” such as Airports, Bus Stops, etc. 4. The Travel Expert Resolver service, which uses the Semantic Graph Manager to provide “packaged” service discovery from the Semantic Web Service Registry can generate Offer Items for a given Route during the Shopping process. The content of related Work Packages with the IT2Rail project is not detailed in this document: readers are referred to the documents listed in the Referenced Documents chapter of this document. All terms and acronyms are defined in the IT2Rail glossary.

  • Thinking Outside the Tbox
    Thinking Outside the TBox Multiparty Service Matchmaking as Information Retrieval David J. Lambert School of Informatics University of Edinburgh I V N E R U S E I T H Y T O H F G E R D I N B U Doctor of Philosophy Centre for Intelligent Systems and their Applications School of Informatics University of Edinburgh 2009 Abstract Service oriented computing is crucial to a large and growing number of computational undertakings. Central to its approach are the open and network-accessible services provided by many different organisations, and which in turn enable the easy creation of composite workflows. This leads to an environment containing many thousands of services, in which a programmer or automated composition system must discover and select services appropriate for the task at hand. This discovery and selection process is known as matchmaking. Prior work in the field has conceived the problem as one of sufficiently describing individual services using formal, symbolic knowledge representation languages. We review the prior work, and present arguments for why it is optimistic to assume that this approach will be adequate by itself. With these issues in mind, we examine how, by reformulating the task and giving the matchmaker a record of prior service performance, we can alleviate some of the problems. Using two formalisms—the incidence calculus and the lightweight coordination calculus—along with algorithms inspired by information retrieval techniques, we evolve a series of simple matchmaking agents that learn from experience how to select those services which performed well in the past, while making minimal demands on the service users.

The Resource Description Framework and its Schema Fabien L. Gandon, INRIA Sophia Antipolis Reto Krummenacher, STI Innsbruck Sung-Kook Han, STI Innsbruck Ioan Toma, STI Innsbruck 1. Abstract RDF is a framework to publish statements on the web about anything. It allows anyone to describe resources, in particular Web resources, such as the author, creation date, subject, and copyright of an image. Any information portal or data-based web site can be interested in using the graph model of RDF to open its silos of data about persons, documents, events, products, services, places etc. RDF reuses the web approach to identify resources (URI) and to allow one to explicitly represent any relationship between two resources.

  • Semantic Web Service Selection Based on Service Provider's
    D A D’Mello et al: SEMANTIC WEB SERVICE SELECTION BASED ON BUSINESS OFFERINGS Semantic Web Service Selection Based on Service Provider’s Business Offerings Demian Antony D’Mello V.S. Ananthanarayana Department of Computer Science and Engineering Department of Information Technology St. Joseph Engineering College, Mangalore National Institute of Technology Karnataka Karnataka, INDIA – 575 028 SrinivasNagar, INDIA – 575 025 e-mail: [email protected] e-mail: [email protected] Abstract—Semantic Web service discovery finds a match between the service requirement and service advertisements based on the semantic descriptions. The matchmaking mechanism might find semantically similar Web services having same matching score. In this paper, the authors propose the semantic Web service selection mechanism which distinguishes semantically similar Web services based on the Quality of Service (QoS) and Business Offerings (BO). To realize the semantic Web service discovery and selection (ranking), we propose the semantic broker based Web service architecture which recommends the best match for the requester based on the requested functionality, quality and business offerings. The authors design the semantic broker which facilitates the provider to advertise the service by creating OWL-S service profile consisting information related to functionality, quality and business offerings. After the service advertisement, the broker computes and records matchmaking information to improve the performance (service query time) of discovery and selection process. The broker also reads requirements from the requester and finds the best (profitable) Web service by matching and ranking the advertised services based on the functionality, capability, quality and business offering. Keywords-Semantic broker, Service selection, Quality of Service, Business offering, Ontology I.

  • Universitetet I Oslo
    UNIVERSITY OF OSLO Department of informatics Semantic Technologies and Publish/Subscribe in Support of Distributed Decision Making Master thesis 60 credits Joachim Reitan 04.05 2009 Abstract Semantic technologies are a family of specifications and accompanying tools that aim to raise the level of data processing from the syntactic to the se- mantic. The research community expects this to bring important advantages to information integration and sharing, culminating with the realisation of a semantic web. Publish/subscribe is a paradigm for asynchronous exchange of messages between anonymous and loosely coupled clients. The routing of messages is based on the expressed information need of the receiving clients. This thesis outlines the design and properties of a publish/subscribe notification service that uses semantic technologies for selective filtering and routing of notifications. In addition, it discusses how the proposed solution might be applied to a specific domain. Network Centric Warfare (NCW) is chosen for application domain. NCW is a military doctrine with the ambition of using information technology to reform the way military forces are organised and operate. Acknowledgements First of all, I would like to thank my supervisor, Professor Josef Noll at UniK. You have been very valuable in leading me onto the right track, pointing out things I have overlooked and, not least, stopped me from getting lost in every possible digression along the way. Then I would like to thank my employer, Forsvarets Forskningsinstitutt, and in particular Frank Steder and Rune Stensrud for accepting this long period of partial absence. Last, but above all, I would like to thank Ellen Skjold Kv˚ale,my dear girlfriend.

  • A Registry Service As a Foundation for Brokering Mathematical Services
    A Registry Service as a Foundation for Brokering Mathematical Services Rebhi Baraka Olga Caprotti Wolfgang Schreiner ∗ Research Institute for Symbolic Computation (RISC-Linz) Johannes Kepler University, Linz, Austria frbaraka,ocaprott,[email protected] February 2004 Abstract In this report, we present our results of developing a framework for publishing and discovering mathematical service descriptions in a registry. The registry is based on and extends the ebXML registry to handle mathematical service descriptions based on the MSDL specification developed in the framework of the MathBroker project. This work serves our ultimate goal to produce a \semantic broker" where services register their problem solving capabilities and clients submit task descriptions; the broker then determines the suitable services and returns them to the client for invocation.
