    Abstract
    For the sake of national security, very large volumes of data and information are generated and gathered daily. Much of this data and information is written in different languages, stored in different locations, and may be seemingly unconnected. Crosslingual semantic interoperability is a major challenge to generate an overview of this disparate data and information so that it can be analyzed, shared, searched, and summarized. The recent terrorist attacks and the tragic events of September 11, 2001 have prompted increased attention an national security and criminal analysis. Many Asian countries and cities, such as Japan, Taiwan, and Singapore, have been advised that they may become the next targets of terrorist attacks. Semantic interoperability has been a focus in digital library research. Traditional information retrieval (IR) approaches normally require a document to share some common keywords with the query. Generating the associations for the related terms between the two term spaces of users and documents is an important issue. The problem can be viewed as the creation of a thesaurus. Apart from this, terrorists and criminals may communicate through letters, e-mails, and faxes in languages other than English. The translation ambiguity significantly exacerbates the retrieval problem. The problem is expanded to crosslingual semantic interoperability. In this paper, we focus an the English/Chinese crosslingual semantic interoperability problem. However, the developed techniques are not limited to English and Chinese languages but can be applied to many other languages. English and Chinese are popular languages in the Asian region. Much information about national security or crime is communicated in these languages. An efficient automatically generated thesaurus between these languages is important to crosslingual information retrieval between English and Chinese languages. To facilitate crosslingual information retrieval, a corpus-based approach uses the term co-occurrence statistics in parallel or comparable corpora to construct a statistical translation model to cross the language boundary. In this paper, the text based approach to align English/Chinese Hong Kong Police press release documents from the Web is first presented. We also introduce an algorithmic approach to generate a robust knowledge base based an statistical correlation analysis of the semantics (knowledge) embedded in the bilingual press release corpus. The research output consisted of a thesaurus-like, semantic network knowledge base, which can aid in semanticsbased crosslingual information management and retrieval.

    Abstract
    The CACAO Project (Cross-language Access to Catalogues and Online Libraries) has been designed to implement natural language processing and cross-language information retrieval techniques to provide cross-language access to information in libraries, a critical issue in the linguistically diverse European Union. This project report addresses two metadata-related challenges for the library community in this context: "false friends" (identical words having different meanings in different languages) and term ambiguity. The possible solutions involve enriching the metadata with attributes specifying language or the source authority file, or associating potential search terms to classes in a classification system. The European Library will evaluate an early implementation of this work in late 2008.

    Abstract
    Since several years it has been observed that information offered by different knowledge producing institutions on the internet is more and more interlinked. This tendency will increase, because the fragmented information offers on the internet make the retrieval of information difficult as even impossible. At the same time the quantity of information offered on the internet grows exponentially in Europe - and elsewhere - due to many digitization projects. Insofar as funding institutions base the acceptance of projects on the observation of certain documentation standards the knowledge created will be retrievable and will remain so for a longer time. Otherwise the retrieval of information will become a matter of chance due to the limits of fragmented, knowledge producing social groups.

    Abstract
    An issue currently at the forefront of digital library research is the prevalence of disparate terminologies and the associated limitations imposed on user searching. It is thought that semantic interoperability is achievable by improving the compatibility between terminologies and classification schemes, enabling users to search multiple resources simultaneously and improve retrieval effectiveness through the use of associated terms drawn from several schemes. This column considers the terminology issue before outlining various proposed methods of tackling it, with a particular focus on terminology mapping.

    Abstract
    Klassische bibliothekarische Indexierungswerkzeuge werden bis heute nur selten fürs Retrieval nutzbar gemacht; die Wichtigkeit, verschiedene dieser Vokabularien zu harmonisieren und integriert zu verwenden, ist noch immer keine Selbstverständlichkeit. Im Rahmen des DFG-Projektes "CrissCross" wird, ausgehend von der deutschen Ausgabe der Dewey-Dezimalklassifikation, eine Verknüpfung zwischen der DDC und der Schlagwortnormdatei (SWD) aufgebaut, um eine verbale Suche über klassifikatorisch erschlossene Bestände zu ermöglichen. Als Verbreiterung der Basis des verbalen Zugriffs wird außerdem das Mapping der amerikanischen LCSH und des französischen RAMEAU angestrebt. Nach einer kurzen Vorstellung von CrissCross und der Abgrenzung gegenüber ähnlichen Unterfangen werden Rückwirkungen semantischer Integration auf die verknüpften Vokabulare diskutiert. Wie müssen und können sich z.B. Thesauri verändern, wenn sie mit anderen (strukturheterologen) Systemen verknüpft sind? Dabei liegt ein Schwerpunkt der Analyse auf dem semantischen Verhältnis üblicher Mappingrelationen zu den verknüpften Begriffen (besonders im Hinblick auf Polysemie). Außerdem wird der Mehrwert fürs Retrieval auf der Basis solcher Wissensorganisationssysteme, z.B. durch automatisierten Zugriff über Ontologien, diskutiert.

    Abstract
    In this paper the following problem is discussed: Which possibilities exist to integrate localized knowledge into knowledge structures like classification systems or other documentary languages for the design of OPACs and information systems? It is proposed to combine a de-localized classificatory structure - best describes as 'ontological spine' - with multilingual semantic networks. Each of these networks should represent the respective localized knowledge along an extended set of typed semantic relations serving as entry points vocabulary as well as a semantic basis for navigational purposes within the localized knowledge context. The spine should enable a link between well-known and not well-known knowledge structures.

    Abstract
    Work in establishing interoperability between Subject Heading Languages (SHLs) in Europe is fairly recent and much work is still needed before users can successfully conduct subject searches across information resources in European libraries. Over the last 25 years many subject heading lists were created or developed from existing ones. Obstacles for effective interoperability have been progressively lifted which has paved the way for interoperability projects to achieve some encouraging results. This paper will look at interoperability approaches in the area of subject indexing tools and will present a short overview of the development of European SHLs. It will then look at the conditions necessary for effective and comprehensive interoperability using the method of linking subject headings, as used by the »Multilingual Access to Subject Headings project« (MACS).
