D3.3 Initial Technical & Logical Architecture and Future Work
D3.3 Initial Technical & Logical Architecture and future work recommendations ECP 2008 DILI 558001 Europeana v1.0 D3.3 Initial Technical & Logical Architecture and future work recommendations Deliverable number D3.3 Dissemination level Public Delivery date 30 July 2010 Status Final Makx Dekkers, Stefan Gradmann, Jan Author(s) Molendijk eContentplus This project is funded under the eContentplus programme1, a multiannual Community programme to make digital content in Europe more accessible, usable and exploitable. 1 OJ L 79, 24.3.2005, p. 1. 1/14 D3.3 Initial Technical & Logical Architecture and future work recommendations 1. Introduction This deliverable has two tasks: To characterise the technical and logical architecture of Europeana as a system in its 1.0 state (that is to say by the time of the ‘Rhine’ release To outline the future work recommendations that can reasonably be made at that moment. This also provides a straightforward and logical structure to the document: characterisation comes first followed by the recommendations for future work. 2. Technical and Logical Architecture From a high-level architectural point of view, Europeana.eu is best characterized as a search engine and a database. It loads metadata delivered by providers and aggregators into a database, and uses that database to allow users to search for cultural heritage objects, and to find links to those objects. Various methods of searching and browsing the objects are offered, including a simple and an advanced search form, a timeline, and an openSearch API. It is also important to describe what Europeana.eu does not do, even though people sometimes expect it to. -

Description Logics
Description Logics Franz Baader1, Ian Horrocks2, and Ulrike Sattler2 1 Institut f¨urTheoretische Informatik, TU Dresden, Germany [email protected] 2 Department of Computer Science, University of Manchester, UK {horrocks,sattler}@cs.man.ac.uk Summary. In this chapter, we explain what description logics are and why they make good ontology languages. In particular, we introduce the description logic SHIQ, which has formed the basis of several well-known ontology languages, in- cluding OWL. We argue that, without the last decade of basic research in description logics, this family of knowledge representation languages could not have played such an important rˆolein this context. Description logic reasoning can be used both during the design phase, in order to improve the quality of ontologies, and in the deployment phase, in order to exploit the rich structure of ontologies and ontology based information. We discuss the extensions to SHIQ that are required for languages such as OWL and, finally, we sketch how novel reasoning services can support building DL knowledge bases. 1 Introduction The aim of this section is to give a brief introduction to description logics, and to argue why they are well-suited as ontology languages. In the remainder of the chapter we will put some flesh on this skeleton by providing more technical details with respect to the theory of description logics, and their relationship to state of the art ontology languages. More detail on these and other matters related to description logics can be found in [6]. Ontologies There have been many attempts to define what constitutes an ontology, per- haps the best known (at least amongst computer scientists) being due to Gruber: “an ontology is an explicit specification of a conceptualisation” [47].3 In this context, a conceptualisation means an abstract model of some aspect of the world, taking the form of a definition of the properties of important 3 This was later elaborated to “a formal specification of a shared conceptualisation” [21]. -
Will the Semantic Web Scale?
Panel Discussion P3: Will the Semantic Web scale? New York Sheraton May 19th, 2004 Proposers: Panelists: Organizers: - Raphael Volz - Dr. Cathy Marshall - Raphael Volz - Carole Goble - Prof. Dr. Alon Y. Halevy - Daniel Oberle - Rudi Studer - Prof. Dr. Jürgen Angele - Prof. Dr. Ian Horrocks Panelist 1 Dr. Cathy Marshall Microsoft Corporation Texas A+M University Why the Semantic Web won’t scale the scaled semantic web seen as mass-market product “the Flowbee uses the suction power of your household vacuum to draw the hair up to the desired length, and then gives it a perfect cut.....every time.” Three important questions: • Will it really work? • Who needs it? • Is it safe? 3 will it work? evaluating the semantic web as metadata • compare the semantic web to a widely adopted metadata scheme like the MARC record used for library cataloging – MARC practitioners are members of a community and are trained to create metadata – MARC reduces interpretive load by careful choice of attributes, authority lists, & cataloging rules (AACR, e.g.) to constrain values – MARC records are controlled for interoperability and consistency in various ways (e.g. by clearinghouses like OCLC) – so... on-line catalog (OPAC) users know what to expect 4 will it work? evaluating the semantic web as metadata • by contrast, the semantic web is subject to the following pitfalls as it scales: – social structures for creating universal semantic web metadata are missing (local culture/practices/needs prevail) – semantic web metadata requires substantial interpretation of domain knowledge; underlying assumptions about use are highly situated – no way of ensuring interoperability, consistency, accuracy • e.g. -

They are popular with search and e-commerce com- Web; linked data; scientific panies and could address the biggest problems in scientific communication, research; machine learning according to Sören Auer of the Technische Informationsbibliothek and Leibniz University of Hannover. In his NASIG vision session, Auer introduced attendees to knowledge graphs and explained how they could make scientific research more discoverable, efficient, and collaborative. Challenges include incentiviz- ing researchers to participate and creating the training data needed to auto- mate the generation of knowledge graphs in all fields of research. Change in the digital world Thank you to Violeta Ilik and the NASIG Program Planning Committee for inviting me to this conference. I would like to show you where I come from. Leibniz University of Hannover has a castle that belonged to a prince, and next to the castle is the Technische Informationsbibliothek (TIB), responsible for supporting the scientific and technology community in Germany with publications, access, licenses, and digital information services. Figure 1 is an example of a knowledge graph about TIB. The basic ingredients of a knowledge graph are entities and relationships. We are the library of Leibniz University of Hannover and we are a member of Leibniz Association (a German research association). -
VIVO: a Semantic Approach to Scholarly Networking and Discovery
VIVO A Semantic Approach to Scholarly Networking and Discovery Synthesis Lectures on Semantic Web: Theory and Technology Editors James Hendler, Rensselaer Polytechnic Institute Ying Ding, Indiana University Synthesis Lectures on the Semantic Web: Theory and Application is edited by James Hendler of Rensselaer Polytechnic Institute. Whether you call it the Semantic Web, Linked Data, or Web 3.0, a new generation of Web technologies is offering major advances in the evolution of the World Wide Web. As the first generation of this technology transitions out of the laboratory, new research is exploring how the growing Web of Data will change our world. While topics such as ontology-building and logics remain vital, new areas such as the use of semantics in Web search, the linking and use of open data on the Web, and future applications that will be supported by these technologies are becoming important research areas in their own right. Whether they be scientists, engineers or practitioners, Web users increasingly need to understand not just the new technologies of the Semantic Web, but to understand the principles by which those technologies work, and the best practices for assembling systems that integrate the different languages, resources, and functionalities that will be important in keeping the Web the rapidly expanding, and constantly changing, information space that has changed our lives. Topics to be included: • Semantic Web Principles from linked-data to ontology design • Key Semantic Web technologies and algorithms • Semantic Search -

Ontology-driven systems with reasoning capabilities in the legal field are now better understood. Legal concepts are not discrete, but make up a dynamic continuum between common sense terms, specific technical use, and professional knowledge, in an evolving institutional reality. Thus, the tension between a plural understanding of regulations and a more general understanding of law is bringing into view a new landscape in which general legal frameworks—grounded in well-known legal theories stemming from 20th-century c. legal positivism or sociological jurisprudence—are made compatible with specific forms of rights management on the Web. In this sense, Semantic Web tools are not only being designed for information retrieval, classification, clustering, and knowledge management. -
