Proceedings of the Workshop on Knowledge Transformation for the Semantic Web KTSW 2002 I B. Omelayenko, M. Klein (eds.) Proceedings of the Workshop on Knowledge Transformation for the Semantic Web KTSW 2002 Workshop W7 at the 15-th European Conference on Artificial Intelligence 23 July 2002, Lyon, France www.cs.vu.nl/˜borys/events/KTSW02 Preface The vision of the Semantic Web envisages the Web enriched with numerous domain ontologies, which specify formal se- mantics of data, allowing various intelligent services to perform knowledge-level information transformation, search and retrieval. Recent successful projects in the ontology area have resulted at creation of thousands ontologies, development of several ontology-based annotation tools and inference engines. However, the absence of an efficient transformation technology for distributed and evolving knowledge hampers further developments of the Semantic Web area. Preliminary non-automated knowledge transformation approaches, experimental research prototypes and early proposals of transformation languages need to evolve into a working technology with solid theoretical grounds and powerful tool support. The workshop attracted a number of high-quality submissions concerning different transformation issues and models pre- sented in the present book. The book is opened with an extended abstract of the invited talk of F. Casati presenting a discussion about the role of services at the Semantic Web. The first section of the proceedings is devoted to model transformation approaches. The paper on ‘Effective schema conver- sions between XML and relational models’ by D. Lee, M. Mani, and W. Chu is followed by the paper on ‘Transforming UML domain descriptions into configuration knowledge bases for the Semantic Web’ by A. Felfernig, G. Friedrich, D. Jannach, M. Stumptner, and M. Zanker. Generic model transformation issues are discussed in the paper ‘On modeling conformance for flexible transformation over data models’ by S. Bowers and L. Declambre. Specific modeling issues are again discussed in the second section. Namely, the problem of ‘Tracking changes in RDF(S) repositories’ by A. Kiryakov and D. Ognyanov, ‘Tracing data lineage using schema transformation pathways’ by H. Fan and A. Poulovassilis, and ‘An algebra for the composition of ontologies’ by P. Mitra and G. Wiederhold. The next section of the book is devoted to the papers on mapping conceptual models. First, ‘Knowledge representation and transformation in ontology-based data integration’ by S. Castano and A. Ferrara, then ‘MAFRA -An Ontology MAp- ping FRAmework in the context of the Semantic Web’ by A. Maedche, B. Motik, N. Silva and R. Volz. These are followed by application-driven approaches ‘Conceptual normalization of XML data for interoperability in tourism’ by O. Fodor, M. Dell’Erba, F. Ricci, A. Spada and H. Werthner; and ‘RDFT: a mapping meta-ontology for business integration’ by B. Ome- layenko. The fourth section contains the papers discussing configuration issues: ‘Enabling services for distributed environments: ontology extraction and knowledge-base characterization’ by D. Sleeman, D. Robertson, S. Potter and M. Schorlemmer; ‘The ‘Family of Languages’ approach to semantic interoperability’ by J. Euzenat and H. Stuckenschmidt; and ‘A logic programming approach on RDF document and query transformation’ by J. Peer. The last section is devoted to poster presentations and system demonstrations: ‘Information retrieval system based on graph matching’ by T. Miyata and K. Hasida; ‘Formal knowledge management in distributed environments’ by M. Schorlemmer, S. Potter, D. Robertson, and D. Sleeman; ‘Distributed semantic perspectives’ by O. Hoffmann and M. Stumptner; ‘The ontology translation problem’ by O. Corcho. We would like to thank the authors for their contributions and wish you to enjoy reading the book.

  • JSON Application Programming Interface for Discrete Event Simulation Data Exchange
    JSON Application Programming Interface for Discrete Event Simulation data exchange Ioannis Papagiannopoulos Enterprise Research Centre Faculty of Science and Engineering Design and Manufacturing Technology University of Limerick Submitted to the University of Limerick for the degree of Master of Engineering 2015 1. Supervisor: Prof. Cathal Heavey Enterprise Research Centre University of Limerick Ireland ii Abstract This research is conducted as part of a project that has the overall aim to develop an open source discrete event simulation (DES) platform that is expandable, and modular aiming to support the use of DES at multi-levels of manufacturing com- panies. The current work focuses on DES data exchange within this platform. The goal of this thesis is to develop a DES exchange interface between three different modules: (i) ManPy an open source discrete event simulation engine developed in Python on the SimPy library; (ii) A Knowledge Extraction (KE) tool used to populate the ManPy simulation engine from shop-floor data stored within an Enterprise Requirements Planning (ERP) or a Manufacturing Execution System (MES) to allow the potential for real-time simulation. The development of the tool is based on R scripting language, and different Python libraries; (iii) A Graphical User Interface (GUI) developed in JavaScript used to provide an interface in a similar manner to Commercial off-the-shelf (COTS) DES tools. In the literature review the main standards that could be used are reviewed. Based on this review and the requirements above, the data exchange format standard JavaScript Object Notation (JSON) was selected. The proposed solution accom- plishes interoperability between different modules using an open source, expand- able, and easy to adopt and maintain, in an all inclusive JSON file.

  • Virtuoso Sponger
    Virtuoso Sponger Situation Analysis Recent estimates (circa. March '09) from the Linked Open Data (LOD) community put the size of burgeoning Web of Linked Data at approximately 4.5 billion triples; in reality, this number is much larger due to the fact that the LOD community estimates are basically approximations of the data from the LOD Cloud pictorial which is primarily based on the following Linked Data source types: Loads from public RDF dump archives Loads from dumps released by crawlers such as PingTheSemanticWeb, Sindice, and Falcons What these estimates do not cover is the amount of RDF based Linked Data generated "on the fly" by RDF middleware technologies (aka. RDFizers). Naturally, tracking the count of this form of Web is somewhat mercurial due to the fact that all of the RDFized data isn't necessarily available via a public RDF archive dump. This white paper covers Virtuoso's in-built RDFizer middleware popularly known as the "Sponger"; an example of a very powerful cross platform solution for generating RDF Linked Data "on the fly". The Sponger exposes its service via the Virtuoso SPARQL Engine, Content Crawler, and a RESTful API. Other facets of Virtuoso's Linked Data related feature set are explored in the accompanying white papers Virtuoso RDF Views - Getting Started Guide and Deploying Linked Data .

  • See Also... a Library Weblog by Steve Lawson
    What the world needs now is another library weblog like I need a hole in my head August 17, 2005 At least that's what I thought after reading over Walt Crawford's investigation of the "biblioblogosphere" in the September Cites & Insights (pdf link). I knew there were a lot of library weblogs--I subscribe to close to thirty in my RSS reader--but Crawford analyzed over 230 library-related blogs, and ran down sixty of the blogs with the widest reach (according to his interpretation of his data; if you'd like to interpret it yourself, he's made it available as an Excel spreadsheet). The likelihood of my adding something entirely new to that mix seems low. And yet, here we are. This is the first real post to my new library weblog, See Also. While I am obviously feeling a little self-conscious about adding my blog to those 230+ that are already out there, I'm also very excited about the idea of thinking, writing, and conversing about libraries, librarianship, and more. I have had other blogs in the past, but most of those were just my outboard brain, a parking place for URLs I didn't want to lose (now I just use del.icio.us). I made no attempt to build a readership, to communicate, to connect. But over the last year as I read more and more library weblogs as they hashed out Gormangate and tried to understand the implications of tags and folksonomies, I wanted to become part of the conversation. I left the occasional comment, but it seemed like I needed a home base if I was really going to take part.
