    Abstract
    Das Hauptthema dieser Tagung - Multimedia - beschäftigt sich mit der Vielfalt der Medien und Quellen, mit denen wir es heute zu tun haben. Da liegt es nahe, sich auch mit einer anderen Form der Vielfalt, dem Thema Mehrsprachigkeit zu beschäftigen. Und die Veranstalter dieser Tagung waren der Meinung, dass ein Schweizer dazu mit Sicherheit etwas zu sagen habe. Das ist insofern richtig, als wir in einem mehrsprachigen Land leben und mit diesem Problem im Alltag vertraut sind, sowohl im täglichen Leben, wie auch eben im dokumentarischen Alltag. Aus dieser praktischen Sicht und nicht als Sprachwissenschafter, der ich nicht bin, möchte ich mich dem Thema nähern. Die Vielfalt der deutschen Sprache: Wenn die Schweiz ein mehrsprachiges Land ist - ist dann Deutschland im Gegensatz dazu ein einsprachiges Land? Auf den ersten Blick sicher ja - in Deutschland spricht man deutsch - aber die Sache ist doch nicht so einfach. Natürlich leben auch hier, wie überall, Menschen aus anderen Ländern mit anderen Muttersprachen - in dieser Optik gibt es wohl fast nur mehrsprachige Länder. Aber auch wenn wir nur die einheimische Bevölkerung mit deutschem Pass betrachten, ist die Sache nicht so eindeutig. Zwar haben sie das Deutsche als gemeinsame Sprache, die von allen gesprochen und verstanden wird. Aber die eigentliche Muttersprache der Deutschen oder mindestens einer grossen Mehrheit ist nicht das Hochdeutsche, sondern einer der vielen Dialekte. Diese Dialekte sind ja höchst unterschiedlich und einem Bayern oder Schwaben geht es sicher nicht anders, als es mir vor Jahren ergangen ist, als ich in Norddeutschland erstmals plattdeutsch sprechen hörte: ich hab nicht mal mehr Bahnhof verstanden und benötigte einige Wochen, bis ich der Unterhaltung wenigstens in groben Zügen folgen konnte. Das Hochdeutsche ist da der gemeinsame Nenner und ermöglichst erst die Verständigung, auch wenn es mit vielfältigen Akzenten und regional eingefärbtem Vokabular gesprochen wird. In diesem Sinne ist die Situation nicht anders als in der deutschsprachigen Schweiz, wo auch ganz unterschiedliche Dialekte gesprochen werden. Allerdings gibt es doch einen wichtigen Unterschied: Hier in Deutschland ist Hochdeutsch die allgemeine Umgangssprache sowohl in der mündlichen wie in der schriftlichen Kommunikation. Dialekte werden im privaten Bereich gesprochen, aber im öffentlichen Bereich, im Geschäftsleben, in der Wissenschaft etc. ist Hochdeutsch die Umgangssprache.

    "Unsere Sitzung fand diesmal am 13. 9. 2005 in Bozen im Rahmen der ODOK statt. Es waren daher auch viele interessierte Südtiroler und italienische Sacherschließungskollegen/-innen zu Gast. Eine der beiden Konferenzsprachen war Englisch, und so konnten wir Mehrsprachigkeit, das Thema unserer Sitzung und der beiden Gastvorträge, gleich selbst praktizieren. Patrice LANDRY, der Leiter der Sacherschließung an derSLB in Bern, der seit kurzem den Vorsitz der IFLA-Sektion "Classification and Indexing" und der Arbeitsgruppe "Guidelines for subject access for national bibliographic agencies" übernommen hatte, referierte über den jüngsten Stand des Projekts MACS (Multilingual Access to Subjects) und ließ uns am Nachmittag in seinem Workshop hinter die Kulissen der bereits mit echten Titeldaten operierenden Suchoberfläche blicken. Er zeigte die verschiedenen Recherche- und Editier-Funktionen im Management Linking System und brachte Beispiele für die kooperative Bearbeitung an einigen Datensätzen der bisher bereits miteinander verzahnten Normdateien SWD, LCSH und RAMEAU. Schließlich eröffnete er Ausblicke auf die künftige Einbindung weiterer Sprachen, etwa des Italienischen durch den Soggetario und auf die Anreicherung der Daten, etwa mit DDC-Notationen durch die Nähe zum DDB-Projekt "CrissCross". Federica PARADISI, die in der Sacherschließungsabteilung der BNC in Florenz sowohl für die italienische Übersetzung der DDC und deren Anwendung in ganz Italien als auch für die Überarbeitung des seit 1956 existierenden italienischen Wortschatzes für die verbale Erschließung und für dessen Aufbereitung zu einer modernen, bald auch elektronischen Normdatei zuständig ist und an der Erstellung der italienischen Nationalbibliografie mitwirkt, hat zuletzt gemeinsam mit Anna Lucarelli den Prototyp des "Nuovo Soggetario" erarbeitet und stellte dieses umfangreiche Projekt vor. Der von ihr skizzierte Zeitplan gibt Anlass zur Hoffnung, dass MACS für die Auffindung beschlagworteter Literatur in Bibliothekskatalogen schon in einem Jahr um einen sprachlichen Zugang reicher sein könnte. Beide Gastreferenten/-innen standen dem Auditorium im Anschluss an die Präsentationen für Fragen zur Verfügung, und die neuen fachlichen Kontakte vertieften sich in den Pausengesprächen noch mehr. Vor der Führung durch die Dewey-Ausstellung im Lichthof der UB Bozen demonstrierte Margit SANDNER zum Abschluss dieses multilingualen Sacherschließungsnachmittags mit einigen Beispielen in deutscherSprache die Suchfunktionen in den beiden Webversionen von DDC Deutsch MelvilSearch (für OPACs) und MelvilClass (für das Klassifizieren) und kündigte an, dass ab Oktober bis Jahresende kostenlose Testaccounts vergeben werden. Wer daran interessiert ist, diese deutschsprachigen Webtools bereits auszuprobieren, wendet sich am besten direkt an Herrn Dr. Lars Svensson in Der Deutschen Bibliothek in Frankfurt: svensson@dbf.ddb.de. Die ab Jänner 2006 gültigen Lizenzbedingungen für "Melvil" entnehmen Sie bitte: http//www.ddc-deutsch.de/licence-melvil.html Noch zwei aktuelle Hinweise: - Informationstag der Arbeitsstelle für Standardisierung (DDB) über aktuelle Tendenzen in Sachen Regelwerke f. Formal- und Sacherschließung, Formate, Normdateien und Datentausch am 15. November in Wien. - Aufsatz über die Zukunft der SWD von Esther Scheven (BD 2005, H. 6, S. 748-773), in dem u. a. auch auf unsere seinerzeitige KofSE-Studie: Schlagwort "Benutzerforschung" ... (VÖB-Mitt. 1997, H. 3-4, S. 28-49) rekurriert wird."

    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
    Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

    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
    This poster explores the customization of DSpace to allow the use of the AGRIS Application Profile metadata standard and the AGROVOC thesaurus. The objective is the adaptation of DSpace, through the least invasive code changes either in the form of plug-ins or add-ons, to the specific needs of the Agricultural Sciences and Technology community. Metadata standards such as AGRIS AP, and Knowledge Organization Systems such as the AGROVOC thesaurus, provide mechanisms for sharing information in a standardized manner by recommending the use of common semantics and interoperable syntax (Subirats et al., 2007). AGRIS AP was created to enhance the description, exchange and subsequent retrieval of agricultural Document-like Information Objects (DLIOs). It is a metadata schema which draws from Metadata standards such as Dublin Core (DC), the Australian Government Locator Service Metadata (AGLS) and the Agricultural Metadata Element Set (AgMES) namespaces. It allows sharing of information across dispersed bibliographic systems (FAO, 2005). AGROVOC68 is a multilingual structured thesaurus covering agricultural and related domains. Its main role is to standardize the indexing process in order to make searching simpler and more efficient. AGROVOC is developed by FAO (Lauser et al., 2006). The customization of the DSpace is taking place in several phases. First, the AGRIS AP metadata schema was mapped onto the metadata DSpace model, with several enhancements implemented to support AGRIS AP elements. Next, AGROVOC will be integrated as a controlled vocabulary accessed through a local SKOS or OWL file. Eventually the system will be configurable to access AGROVOC through local files or remotely via webservices. Finally, spell checking and tooltips will be incorporated in the user interface to support metadata editing. Adapting DSpace to support AGRIS AP and annotation using the semantically-rich AGROVOC thesaurus transform DSpace into a powerful, domain-specific system for annotation and exchange of bibliographic metadata in the agricultural domain.

    Abstract
    A study group representing four European national libraries (the Swiss National Library, Die Deutsche Bibliothek, the Bibliothèque nationale de France and The British Library) recently conducted a study on the possibility of establishing multilingual thesaural links between the headings in the LCSH authority file and the authority files of the German indexing system SWD/RSWK and the French indexing system RAMEAU. The study demonstrated a high level of correspondence in main headings, but also revealed a number of issues requiring further investigation. The study group's findings led to recommendations on the scope for the development of a prototype system for linking the three Subject Heading Languages (SHLs) in the databases of the four institutions

    Abstract
    The Web has become a large repository of documents (or pages) written in many different languages. In this context, traditional information retrieval (IR) techniques cannot be used whenever the user query and the documents being retrieved are in different languages. To address this problem, new cross-language information retrieval (CLIR) techniques have been proposed. In this work, we describe a method for cross-language retrieval of medical information. This method combines query terms and related medical concepts obtained automatically through a categorization procedure. The medical concepts are used to create a linguistic abstraction that allows retrieval of information in a language-independent way, minimizing linguistic problems such as polysemy. To evaluate our method, we carried out experiments using the OHSUMED test collection, whose documents are written in English, with queries expressed in Portuguese, Spanish, and French. The results indicate that our cross-language retrieval method is as effective as a standard vector space model algorithm operating on queries and documents in the same language. Further, our results are better than previous results in the literature.

    Abstract
    Query translation is a viable method for cross-language information retrieval (CLIR), but it suffers from translation ambiguities caused by multiple translations of individual query terms. Previous research has employed various methods for disambiguation, including the method of selecting an individual target query term from multiple candidates by comparing their statistical associations with the candidate translations of other query terms. This paper proposes a new method where we examine all combinations of target query term translations corresponding to the source query terms, instead of looking at the candidates for each query term and selecting the best one at a time. The goodness value for a combination of target query terms is computed based on the association value between each pair of the terms in the combination. We tested our method using the NTCIR-3 English-Korean CLIR test collection. The results show some improvements regardless of the association measures we used.

    Abstract
    Two probabilistic approaches to cross-lingual retrieval are in wide use today, those based on probabilistic models of relevance, as exemplified by INQUERY, and those based on language modeling. INQUERY, as a query net model, allows the easy incorporation of query operators, including a synonym operator, which has proven to be extremely useful in cross-language information retrieval (CLIR), in an approach often called structured query translation. In contrast, language models incorporate translation probabilities into a unified framework. We compare the two approaches on Arabic and Spanish data sets, using two kinds of bilingual dictionaries--one derived from a conventional dictionary, and one derived from a parallel corpus. We find that structured query processing gives slightly better results when queries are not expanded. On the other hand, when queries are expanded, language modeling gives better results, but only when using a probabilistic dictionary derived from a parallel corpus. We pursue two additional issues inherent in the comparison of structured query processing with language modeling. The first concerns query expansion, and the second is the role of translation probabilities. We compare conventional expansion techniques (pseudo-relevance feedback) with relevance modeling, a new IR approach which fits into the formal framework of language modeling. We find that relevance modeling and pseudo-relevance feedback achieve comparable levels of retrieval and that good translation probabilities confer a small but significant advantage.

    Abstract
    Alexandria is an innovation of international impact. It is the only multilingual dictionary for websites and PCs. A double click on a word opens a small window that gives interactive translations between 22 languages and includes meaning, synonyms and associated expressions. It is an ASP application grounded on a semantic network that is portable on any operating system or platform. Behind the application is the Integral Dictionary is the semantic network created by Memodata. Alexandria can be customized with specific vocabulary, descriptive articles, images, sounds, videos, etc. Its domains of application are considerable: e-tourism, online medias, language learning, international websites. Alexandria has also proved to be a basic tool for knowledge management purposes. The application can be customized according to a user or an organization needs. An application dedicated to mobile devices is currently being developed. Future developments are planned in the field of e-tourism in relation with French "pôles de compétitivité".

    Abstract
    In this article the authors present Eurovision, a textbased system for cross-language (CL) image retrieval. The system is evaluated by multilingual users for two search tasks with the system configured in English and five other languages. To the authors' knowledge, this is the first published set of user experiments for CL image retrieval. They show that (a) it is possible to create a usable multilingual search engine using little knowledge of any language other than English, (b) categorizing images assists the user's search, and (c) there are differences in the way users search between the proposed search tasks. Based on the two search tasks and user feedback, they describe important aspects of any CL image retrieval system.

    Abstract
    M-CAST which stands for »Multilingual Content Aggregation System based on TRUST Search Engine« is a multilingual indexing and retrieval system based on semantic technology; it allows asking a question in one language and finding an exact answer in digitalized resources in different languages. It can serve as a monolingual query-answering system as well. Presently, we have a prototype of the M-CAST system; it was developed to evaluate both retrieval effectiveness and correctness of the interpretation process and has been tested in real-world situations. Further research will be done to increase the capabilities of the system. The M-CAST question-answering could be applied in both digital and hybrid libraries, because it enables to pose questions using either a set of search terms or natural-language questions. In addition, it enables to narrow a search in advanced search module using UDC (Universal Decimal Classification) system, which is widely used in libraries.

    Abstract
    Interactive Cross-Language Information Retrieval (CLIR), a process in which searcher and system collaborate to find documents that satisfy an information need regardless of the language in which those documents are written, calls for designs in which synergies between searcher and system can be leveraged so that the strengths of one can cover weaknesses of the other. This paper describes an approach that employs user-assisted query translation to help searchers better understand the system's operation. Supporting interaction and interface designs are introduced, and results from three user studies are presented. The results indicate that experienced searchers presented with this new system evolve new search strategies that make effective use of the new capabilities, that they achieve retrieval effectiveness comparable to results obtained using fully automatic techniques, and that reported satisfaction with support for cross-language searching increased. The paper concludes with a description of a freely available interactive CLIR system that incorporates lessons learned from this research.

    Abstract
    A novel and complex form of information access is cross-language information retrieval: searching for texts written in foreign languages based on native language queries. Although the underlying technology for achieving such a search is relatively well understood, the appropriate interface design is not. The authors present three user evaluations undertaken during the iterative design of Clarity, a cross-language retrieval system for lowdensity languages, and shows how the user-interaction design evolved depending on the results of usability tests. The first test was instrumental to identify weaknesses in both functionalities and interface; the second was run to determine if query translation should be shown or not; the final was a global assessment and focused on user satisfaction criteria. Lessons were learned at every stage of the process leading to a much more informed view of what a cross-language retrieval system should offer to users.

    Abstract
    Thesaural relations have long been used in information retrieval to enrich queries; they have sometimes been used to cluster documents as well. Sometimes the first query to an information retrieval system yields no results at all, or, what can be even more disconcerting, many thousands of hits. One solution is to rephrase the query, improving the choice of query terms by using related terms of different types. A collection of related terms is often called a thesaurus. This chapter describes the lexical-semantic relations that have been used in building thesauri and summarizes some of the effects of using these relational thesauri in information retrieval experiments
