    Abstract
    In order to transfer the Chinese Classified Thesaurus (CCT) into a machine-processable format and provide CCT-based Web services, a pilot study has been conducted in which a variety of selected CCT classes and mapped thesaurus entries are encoded with SKOS. OWL and RDFS are also used to encode the same contents for the purposes of feasibility and cost-benefit comparison. CCT is a collected effort led by the National Library of China. It is an integration of the national standards Chinese Library Classification (CLC) 4th edition and Chinese Thesaurus (CT). As a manually created mapping product, CCT provides for each of the classes the corresponding thesaurus terms, and vice versa. The coverage of CCT includes four major clusters: philosophy, social sciences and humanities, natural sciences and technologies, and general works. There are 22 main-classes, 52,992 sub-classes and divisions, 110,837 preferred thesaurus terms, 35,690 entry terms (non-preferred terms), and 59,738 pre-coordinated headings (Chinese Classified Thesaurus, 2005) Major challenges of encoding this large vocabulary comes from its integrated structure. CCT is a result of the combination of two structures (illustrated in Figure 1): a thesaurus that uses ISO-2788 standardized structure and a classification scheme that is basically enumerative, but provides some flexibility for several kinds of synthetic mechanisms Other challenges include the complex relationships caused by differences of granularities of two original schemes and their presentation with various levels of SKOS elements; as well as the diverse coordination of entries due to the use of auxiliary tables and pre-coordinated headings derived from combining classes, subdivisions, and thesaurus terms, which do not correspond to existing unique identifiers. The poster reports the progress, shares the sample SKOS entries, and summarizes problems identified during the SKOS encoding process. Although OWL Lite and OWL Full provide richer expressiveness, the cost-benefit issues and the final purposes of encoding CCT raise questions of using such approaches.

    "Yahoo hat angekündigt einige der wesentlichen Standards des semantischen Webs in seine Suchmaschine zu integrieren. Das Unternehmen will einige semantische Web-Indexate in seine Suchtechnik einbauen. Anstatt eine lange Liste von Links auszuspucken, könnte eine semantische Suchmaschine verstehen, welche Art von Objekt oder Person gesucht wird und zusätzliche Information anbieten. Die neue Technologie könnte etablierte Angebote unter Druck setzen, erwarten Experten. Google setzt nach wie vor auf konventionelle Technologie. Der Schachzug des Unternehmens könnte der Verbreitung der Technologie erheblichen Auftrieb geben. Trotz des bemerkenswerten Fortschritts des semantischen Webs der vergangenen Jahre habe der durchschnittliche User davon noch nichts bemerkt, meint Amit Kumar, Product Management Director bei Yahoo. Yahoo habe nun gemerkt, dass sich das langsam ändere. Wie in den Anfangstagen des Web würden viele Menschen Daten mit Kennzeichnungen und Indextermen versehen, die semantische Suchmaschinen brauchen, um das Web zu durchsuchen. Yahoo hat erkannt, dass es nun genug Informationen als Grundlage für eine semantische Websuche gibt."

    Abstract
    Important information is often scattered across Web and/or intranet resources. Traditional search engines return ranked retrieval lists that offer little or no information on the semantic relationships among documents. Knowledge workers spend a substantial amount of their time browsing and reading to find out how documents are related to one another and where each falls into the overall structure of the problem domain. Yet only when knowledge workers begin to locate the similarities and differences among pieces of information do they move into an essential part of their work: building relationships to create new knowledge. Information retrieval traditionally focuses on the relationship between a given query (or user profile) and the information store. On the other hand, exploitation of interrelationships between selected pieces of information (which can be facilitated by the use of ontologies) can put otherwise isolated information into a meaningful context. The implicit structures so revealed help users use and manage information more efficiently. Knowledge management tools are needed that integrate the resources dispersed across Web resources into a coherent corpus of interrelated information. Previous research in information integration has largely focused on integrating heterogeneous databases and knowledge bases, which represent information in a highly structured way, often by means of formal languages. In contrast, the Web consists to a large extent of unstructured or semi-structured natural language texts. As we have seen, ontologies offer an alternative way to cope with heterogeneous representations of Web resources. The domain model implicit in an ontology can be taken as a unifying structure for giving information a common representation and semantics. Once such a unifying structure exists, it can be exploited to improve browsing and retrieval performance in information access tools. QuizRDF is an example of such a tool.

    Abstract
    Purpose - The main objective of the AGROVOC Concept Server (CS) is to create a collaborative reference platform and a "one-stop" shop for a pool of commonly used concepts related to agriculture, containing terms, definitions and relationships between terms in multiple languages derived from various sources. This paper aims to address the issues. Design/methodology/approach - The CS offers a centralised facility where the agricultural information management community can build and share agricultural knowledge in a collaborative environment. Findings - The advantages of the CS are its extensibility and modularity that provide the possibility to extend the type of information that can be stored in this system based on user/community needs. Research limitations/implications - Further investigation still needs to be done on the modularisation of the CS (i.e. the creation of separated ontologies that can still be connected, in order to have domain-related ontologies and to allow for better performance of the CS). Practical implications - The CS serves as starting point for the development of specific domain ontologies where multilinguality and the localised representation of knowledge are essential issues. Furthermore, it will offer additional services in order to expose the knowledge to be consumed by other applications. Originality/value - The CS Workbench provides the AGROVOC partners with the possibility to directly and collaboratively edit the AGROVOC CS. It thus provides the opportunity for direct and open "many-to-many" communication links between communities, avoiding decentralised communication between partners and duplication of effort. For the international community, it may allow users to manage, re-use or extend agriculture-related knowledge for better interoperability and for improved services.

    Abstract
    Purpose - The purpose of this paper is to discuss alternative definitions of and approaches to the semantic web. It aims to clarify the relationship between the semantic web, Web 2.0 and Library 2.0. Design/methodology/approach - The paper is based on a literature review and evaluation of systems with semantic web features. It identifies and describes semantic web projects of relevance to libraries and evaluates the usefulness of JeromeDL and other social semantic digital library systems. It discusses actual and potential applications for libraries and makes recommendations for actions needed by researchers and practitioners. Findings - The paper concludes that the library community has a lot to offer to, and benefit from, the semantic web, but there is limited interest in the library community. It recommends that there be greater collaboration between semantic web researchers and project developers, library management systems providers and the library community. Librarians should get involved in the development of semantic web standards, for example, metadata and taxonomies. Originality/value - The paper clarifies the distinction between semantic web and Web 2.0 in a digital library environment. It evaluates and predicts future developments for operational systems.

    Abstract
    The structural and syntactic web put in place in the early 90s is still much the same as what we use today: resources (web pages, files, etc.) connected by untyped hyperlinks. By untyped, we mean that there is no easy way for a computer to figure out what a link between two pages means - for example, on the W3C website, there are hundreds of links to the various organisations that are registered members of the association, but there is nothing explicitly saying that the link is to an organisation that is a "member of" the W3C or what type of organisation is represented by the link. On John's work page, he links to many papers he has written, but it does not explicitly say that he is the author of those papers or that he wrote such-and-such when he was working at a particular university. In fact, the Web was envisaged to be much more, as one can see from the image in Fig. 1 which is taken from Tim Berners Lee's original outline for the Web in 1989, entitled "Information Management: A Proposal". In this, all the resources are connected by links describing the type of relationships, e.g. "wrote", "describe", "refers to", etc. This is a precursor to the Semantic Web which we will come back to later.

    Abstract
    An information-seeking system is described which combines traditional keyword querying of WWW resources with the ability to browse and query against RD annotations of those resources. RDF(S) and RDF are used to specify and populate an ontology and the resultant RDF annotations are then indexed along with the full text of the annotated resources. The resultant index allows both keyword querying against the full text of the document and the literal values occurring in the RDF annotations, along with the ability to browse and query the ontology. We motivate our approach as a key enabler for fully exploiting the Semantic Web in the area of knowledge management and argue that the ability to combine searching and browsing behaviours more fully supports a typical information-seeking task. The approach is characterised as "low threshold, high ceiling" in the sense that where RDF annotations exist they are exploited for an improved information-seeking experience but where they do not yet exist, a search capability is still available.

    Abstract
    Overlapping structures in XML are not symptoms of a misunderstanding of the intrinsic characteristics of a text document nor evidence of extreme scholarly requirements far beyond those needed by the most common XML-based applications. On the contrary, overlaps have started to appear in a large number of incredibly popular applications hidden under the guise of syntactical tricks to the basic hierarchy of the XML data format. Unfortunately, syntactical tricks have the drawback that the affected structures require complicated workarounds to support even the simplest query or usage. In this article, we present Extremely Annotational Resource Description Framework (RDF) Markup (EARMARK), an approach to overlapping markup that simplifies and streamlines the management of multiple hierarchies on the same content, and provides an approach to sophisticated queries and usages over such structures without the need of ad-hoc applications, simply by using Semantic Web tools and languages. We compare how relevant tasks (e.g., the identification of the contribution of an author in a word processor document) are of some substantial complexity when using the original data format and become more or less trivial when using EARMARK. We finally evaluate positively the memory and disk requirements of EARMARK documents in comparison to Open Office and Microsoft Word XML-based formats.

    Abstract
    Over the past 3 years, the semantic web activity has gained momentum with the widespread publishing of structured data as RDF. The Linked Data paradigm has therefore evolved from a practical research idea into a very promising candidate for addressing one of the biggest challenges in the area of the Semantic Web vision: the exploitation of the Web as a platform for data and information integration. To translate this initial success into a world-scale reality, a number of research challenges need to be addressed: the performance gap between relational and RDF data management has to be closed, coherence and quality of data published on theWeb have to be improved, provenance and trust on the Linked Data Web must be established and generally the entrance barrier for data publishers and users has to be lowered. In this vision statement we discuss these challenges and argue, that research approaches tackling these challenges should be integrated into a mutual refinement cycle. We also present two crucial use-cases for the widespread adoption of linked data.
