    Abstract
    This paper is about a better understanding of the structure and dynamics of science and the usage of these insights for compensating the typical problems that arises in metadata-driven Digital Libraries. Three science model driven retrieval services are presented: co-word analysis based query expansion, re-ranking via Bradfordizing and author centrality. The services are evaluated with relevance assessments from which two important implications emerge: (1) precision values of the retrieval services are the same or better than the tf-idf retrieval baseline and (2) each service retrieved a disjoint set of documents. The different services each favor quite other - but still relevant - documents than pure term-frequency based rankings. The proposed models and derived retrieval services therefore open up new viewpoints on the scientific knowledge space and provide an alternative framework to structure scholarly information systems.

    Abstract
    Die Verwendung von Erschließungsinstrumenten zur Beschreibung von Informationsressourcen kann Effizienz und Effektivität thematischer Recherchen wesentlich steigern: standardisierte Begriffe unterstützen Recall und Precision begrifflicher Suchen; Ausweisung von Relationen bietet die Grundlage für explorative Suchprozesse. Eine zusätzliche Steigerung der Funktionalitäten des Retrievals kann mittels einer Ausdifferenzierung und Spezifizierung der in Normdaten enthaltenen semantischen Informationen erreicht werden, die über die in Thesauri und Klassifikationen verbreiteten grundlegenden Relationstypen (äquivalent, hierarchisch, assoziativ) hinausgehen. In modernen Informationsräumen, in denen Daten verschiedener Institutionen über eine Plattform zeit- und ortsunabhängig zugänglich gemacht werden, können einzelne Wissenssysteme indes nur unzureichend das Information Retrieval unterstützen. Zu unterschiedlich sind die für thematische Suchanfragen relevanten Indexierungsdaten. Eine Verbesserung kann mittels Herstellung von Interoperabilität zwischen den verschiedenen Dokumentationssprachen erreicht werden. Im Vortrag wird dargelegt, in welcher Art und Weise die in Wissenssystemen enthaltenen semantischen Informationen zur Unterstützung thematischer Recherchen optimiert werden können und inwiefern Interoperabilität zwischen Systemen geschaffen werden kann, die gleichwertige Funktionalitäten in heterogenen Informationsräumen gewährleisten. In diesem Zusammenhang wird auch auf aktuelle Mappingprojekte wie das DFG-Projekt CrissCross oder das RESEDA-Projekt, welches sich mit den Möglichkeiten der semantischen Anreicherung bestehender Dokumentationssprachen befasst, eingegangen.

Initiiert durch das Amt für Veröffentlichungen der Europäischen Union (http://publications.europa.eu) waren Bibliothekare und Information Professionals eingeladen, um über die Zukunft mehrsprachiger kontrollierter Vokabulare in Informationssystemen und insbesondere deren Beitrag zum Semantic Web zu diskutieren. Organisiert wurde die Konferenz durch das EuroVoc-Team, das den Thesaurus der Europäischen Union bearbeitet. Die letzte EuroVoc-Konferenz fand im Jahr 2006 statt. In der Zwischenzeit ist EuroVoc zu einem ontologie-basierten Thesaurusmanagementsystem übergegangen und hat systematisch begonnen, Semantic-Web-Technologien für die Bearbeitung und Repräsentation einzusetzen und sich mit anderen Vokabularen zu vernetzen. Ein produktiver Austausch fand mit den Produzenten anderer europäischer und internationaler Vokabulare (z.B. United Nations oder FAO) sowie Vertretern aus Projekten, die an Themen über automatische Indexierung (hier insbesondere parlamentarische und rechtliche Dokumente) sowie Interoperabilitiät zwischen Vokabularen arbeiten, statt.

    Abstract
    Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

    Abstract
    The middle of the 1990s are coined by the increased enthusiasm for the possibilities of the WWW, which has only recently deviated - at least in relation to scientific information - for the differentiated measuring of its advantages and disadvantages. Web Information Retrieval originated as a specialized discipline with great commercial significance (for an overview see Lewandowski 2005). Besides the new technological structure that enables the indexing and searching (in seconds) of unimaginable amounts of data worldwide, new assessment processes for the ranking of search results are being developed, which use the link structures of the Web. They are the main innovation with respect to the traditional "mother discipline" of Information Retrieval. From the beginning, link structures of Web pages are applied to commercial search engines in a wide array of variations. From the perspective of scientific information, link topology based approaches were in essence trying to solve a self-created problem: on the one hand, it quickly became clear that the openness of the Web led to an up-tonow unknown increase in available information, but this also caused the quality of the Web pages searched to become a problem - and with it the relevance of the results. The gatekeeper function of traditional information providers, which narrows down every user query to focus on high-quality sources was lacking. Therefore, the recognition of the "authoritativeness" of the Web pages by general search engines such as Google was one of the most important factors for their success.

    Abstract
    The focus of this paper is the provision of terminology- and classification-based terminologies interoperability data via web services, initially using interoperability data based on the use of a Dewey Decimal Classification (DDC) spine, but with an aim to explore other possibilities in time, including the use of other spines. The High-Level Thesaurus Project (HILT) Phase IV developed pilot web services based on SRW/U, SOAP, and SKOS to deliver machine-readable terminology and crossterminology mappings data likely to be useful to information services wishing to enhance their subject search or browse services. It also developed an associated toolkit to help information services technical staff to embed HILT-related functionality within service interfaces. Several UK information services have created illustrative user interface enhancements using HILT functionality and these will demonstrate what is possible. HILT currently has the following subject schemes mounted and available: DDC, CAB, GCMD, HASSET, IPSV, LCSH, MeSH, NMR, SCAS, UNESCO, and AAT. It also has high level mappings between some of these schemes and DDC and some deeper pilot mappings available.

    ""Sacherschließung - Informationsdienstleistung nach Maß": unter diesem Titel fand am 3. Leipziger Kongress für Information und Bibliothek ("Information und Ethik") eine sehr aufschlussreiche Vortragsreihe statt. Neue Projekte der Vernetzung unterschiedlichst erschlossener Bestände wurden vorgestellt. Auch die Frage, inwieweit man die Nutzerinnen und Nutzer in die Erschließung einbinden kann, wurde behandelt. Die Arbeit der Bibliothekare kann wertvolle Ausgangssituationen für alternative Methoden bieten. Das Zusammenwirken von intellektueller und maschineller Erschließung wird in Zukunft eine große Rolle spielen. Ein Ausweg, um die Erschließung der ständig wachsenden Informationsquellen zu ermöglichen, könnte eine arbeitsteilige Erschließung und eine Kooperation mit anderen Informationseinrichtungen darstellen. Im Mittelpunkt all dieser Überlegungen standen die Heterogenitätsprobleme, die sich durch unterschiedliche Erschließungsregeln, verschiedene Arbeitsinstrumente, verschiedene Sprachen und durch die unterschiedliche Bedeutung der Begriffe ergeben können. Der Nachmittag begann mit einem konkreten Beispiel: "Zum Stand der Heterogenitätsbehandlung in vascoda" (Philipp Mayr, Bonn und Anne-Kathrin Walter, Bonn). Das Wissenschaftsportal vascoda beinhaltet verschiedene Fachportale, und es kann entweder interdisziplinär oder fachspezifisch gesucht werden. Durch die verschiedenen Informationsangebote, die in einem Fachportal vorhanden sind und die in dem Wissenschaftsportal vascoda zusammengefasst sind, entsteht semantische Heterogenität. Oberstes Ziel ist somit die Heterogenitätsbehandlung. Die Erstellung von Crosskonkordanzen (zwischen Indexierungssprachen innerhalb eines Fachgebiets und zwischen Indexierungssprachen unterschiedlicher Fachgebiete) und dem sogenannten Heterogenitätsservice (Term-Umschlüsselungs-Dienst) wurden anhand dieses Wissenschaftsportals vorgestellt. "Crosskonkordanzen sind gerichtete, relevanzbewertete Relationen zwischen Termen zweier Thesauri, Klassifikationen oder auch anderer kontrollierter Vokabulare." Im Heterogenitätsservice soll die Suchanfrage so transformiert werden, dass sie alle relevanten Dokumente in den verschiedenen Datenbanken erreicht. Bei der Evaluierung der Crosskonkordanzen stellt sich die Frage der Zielgenauigkeit der Relationen, sowie die Frage nach der Relevanz der durch die Crosskonkordanz zusätzlich gefundenen Treffer. Drei Schritte der Evaluation werden durchgeführt: Zum einen mit natürlicher Sprache in der Freitextsuche, dann übersetzt in Deskriptoren in der Schlagwortsuche und zuletzt mit Deskriptoren in der Schlagwortsuche mit Einsatz der Crosskonkordanzen. Im Laufe des Sommers werden erste Ergebnisse der Evaluation der Crosskonkordanzen erwartet.
    Einen anderen sehr interessanten Ansatz bot der nächste Vortrag mit dem Titel: "Navigieren zwischen Schlagwort und Notation - Crisscross als Verbindung zwischen SWD und DDC" (Helga Karg, Frankfurt am Main und Guido Bee, Frankfurt am Main). Das Projekt Crisscross versucht durch Verbindung von SWD, LCSH, Rameau und DDC ein benutzergerechtes, multilinguales und thesaurusbasiertes Recherchevokabular zu erstellen. Es wurde eine Konkordanz zwischen SWD, LCSH und Rameau (Projekt MACS) erstellt und in den SWD-Sachschlagwörtern die DDCNotationen vermerkt. Durch die Angabe der Determiniertheit in der SWD kann zwischen "wesentlicher Übereinstimmung von SWD-Term und DDCKlasse", "SWD-Begriff spezifischer als die DDC-Klasse" und SWD-Begriff sowohl "nicht auf einen bestimmten Kontext beschränkt" als auch "SWDBegriff quer zur DDC-Hierarchie" unterschieden werden (siehe auch: Anzeige in MelviIClass).

    Abstract
    Current retrieval and recommendation approaches rely on hard-wired data models. This hinders personalized cus-tomizations to meet information needs of users in a more flexible manner. Therefore, the paper investigates how similarity-basedretrieval strategies can be combined with graph queries to enable users or system providers to explore repositories in the LinkedOpen Data (LOD) cloud more thoroughly. For this purpose, we developed novel content-based recommendation approaches.They rely on concept annotations of Simple Knowledge Organization System (SKOS) vocabularies and a SPARQL-based querylanguage that facilitates advanced and personalized requests for openly available knowledge graphs. We have comprehensivelyevaluated the novel search strategies in several test cases and example application domains (i.e., travel search and multimediaretrieval). The results of the web-based online experiments showed that our approaches increase the recall and diversity of rec-ommendations or at least provide a competitive alternative strategy of resource access when conventional methods do not providehelpful suggestions. The findings may be of use for Linked Data-enabled recommender systems (LDRS) as well as for semanticsearch engines that can consume LOD resources.

    Abstract
    This paper discusses goals, methods and benefits of the conceptual mapping approach conducted within the CrissCross project, where topical headings of the German subject headings authority file Schlagwortnormdatei (SWD) are being mapped to notations of the Dewey Decimal Classification. Project-specific retrieval concepts for improving thematic access in heterogeneous information spaces are outlined and explained on the basis of significant examples.

    Abstract
    This paper describes the basic concepts of terminology services and their role in information retrieval interfaces. Terminology services are consumed by other software applications using machine-to-machine protocols, rather than directly by end-users. An example of a terminology service is the pilot developed by the High Level Thesaurus (HILT) project which has successfully demonstrated its potential for enhancing subject retrieval in operational services. Examples of enhancements in three such services are given. The paper discusses the future development of terminology services in relation to the Semantic Web.

    Abstract
    As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed

    Abstract
    The semantic heterogeneity presented by Web information in the Agricultural domain presents tremendous information retrieval challenges. This article presents work taking place at the Food and Agriculture Organizations (FAO) which addresses this challenge. Based on the analysis of resources in the domain of agriculture, this paper proposes (a) an application profile (AP) for dealing with the problem of heterogeneity originating from differences in terminologies, domain coverage, and domain modelling, and (b) a root application ontology (AAO) based on the application profile which can serve as a basis for extending knowledge of the domain. The paper explains how even a small investment in the enhancement of relations between vocabularies, both metadata and domain-specific, yields a relatively large return on investment.

    Abstract
    XML will have a profound impact on the way data is exchanged on the Internet. An important feature of this language is the separation of content from presentation, which makes it easier to select and/or reformat the data. However, due to the likelihood of numerous industry and domain specific DTDs, those who wish to integrate information will still be faced with the problem of semantic interoperability. In this paper we discuss why this problem is not solved by XML, and then discuss why the Resource Description Framework is only a partial solution. We then present the SHOE language, which we feel has many of the features necessary to enable a semantic web, and describe an existing set of tools that make it easy to use the language.

    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.

    "Am 19. und 20. Juli 2010 fand in der Fachhochschule Köln die internationale Tagung "Concepts in Context - Cologne Conference on Interoperability and Semantics in Knowledge Organization" statt. Ausgerichtet wurde sie mit finanzieller Unterstützung der Deutschen Forschungsgemeinschaft (DFG) vom Institut für Informationsmanagement (IIM) der Fachhochschule Köln in Kooperation mit der Deutschen Nationalbibliothek (DNB). Im Mittelpunkt der Veranstaltung standen Fragen der Modellierung von Interoperabilität und semantischen Informationen in der Wissensorganisation, die einen unmittelbaren thematischen Zusammenhang mit den am Institut für Informationsmanagement angesiedelten Projekten CrissCross und RESEDA aufweisen. Das Programm umfasste 11 Beiträge aus 5 verschiedenen Ländern sowohl zu praktischen als auch zu theoretischen Aspekten der Wissensorganisation unter besonderer Berücksichtigung moderner Technologien, aktueller Entwicklungen und zukunftsbezogener Perspektiven. Der erste Tag war als Abschlussworkshop für das CrissCross-Projekt konzipiert und bot in zwei Sessions neben einem umfassenden Überblick über das Projekt auch weitere Best-Practice-Beispiele für die Gestaltung von Interoperabilität vor allem im Rahmen von Ansätzen der Semantic-Web- und Linked-Data-Initiativen. Eine vertiefte Auseinandersetzung mit sich in der Entwicklung befindlichen oder auch erst kürzlich fertiggestellten Standards und Modellen der Interoperabilität und Wissensorganisation erfolgte am zweiten Tag, der mit einer Keynote von Dagobert Soergel von der University at Buffalo (USA) eröffnet wurde und in zwei weitere Sessions unterteilt war. Zu der Veranstaltung konnten Prof. Dr. Klaus-Dirk Schmitz, Leiter des Kölner Instituts für Informationsmanagement, sowie Ulrike Junger, Leiterin der Abteilung Sacherschließung der Deutschen Nationalbibliothek in Stellvertretung der Generaldirektorin, Dr. Elisabeth Niggemann, ca. 120 Teilnehmer aus insgesamt 16 Ländern begrüßen. Prof. Klaus-Dirk Schmitz stellte in seiner Eröffnungsrede die Fachhochschule Köln und insbesondere das Institut für Informationsmanagement vor und erörterte das Konferenzthema mit Beispielen aus Forschungsgebieten der Terminologiearbeit. Ulrike Junger ging auf die gelungene Zusammenarbeit zwischen der Fachhochschule Köln und der Deutschen Nationalbibliothek ein, die mit dem DFG-Projekt DDC Deutsch begonnen und in dem DFG-Projekt CrissCross eine Fortsetzung gefunden hatte. Eine Einführung in die spezifischen Konferenzinhalte gab schließlich Prof. Winfried Gödert, Leiter des RESEDA-Projekts sowie - seitens der Fachhochschule Köln - des CrissCross-Projekts.
    Die erste Session der Veranstaltung war dem von der DFG geförderten Projekt CrissCross gewidmet, das von der Fachhochschule Köln in Kooperation mit der Deutschen Nationalbibliothek durchgeführt wird. Das Projekt, das 2006 begann und im Herbst diesen Jahres endet, verfolgt das Ziel, ein multilinguales, thesaurusbasiertes und nutzerfreundliches Recherchevokabular zu heterogen erschlossenen Informationsressourcen zu schaffen. Hierzu wird einerseits eine unidirektionale Verbindung zwischen Sachschlagwörtern der Schlagwortnormdatei (SWD) und Notationen der Dewey-Dezimalklassifikation hergestellt, andererseits werden - in Fortführung der in dem Projekt Multilingual Access to Subject Headings (MACS) entwickelten Methodik - häufig verwendete SWD-Schlagwörter mit ihren Äquivalenten in der englischen Schlagwortsprache Library of Congress Subject Headings (LCSH) und der französischen Schlagwortsprache Répertoire d'autorité-matière encyclopédique et alphabétique unifié (RAMEAU) verknüpft. Jan-Helge Jacobs, Katrin Müller und Tina Mengel von der Fachhochschule Köln gaben einen Überblick über das für das Projekt spezifische SWD-DDC-Mapping. Sie erläuterten die zugrunde liegende Methodik und stellten den mit den Daten gegebenen möglichen Mehrwert sowohl zur Verbesserung des Zugangs zur DDC und zu DDC-erschlossenen Informationsressourcen im Allgemeinen als auch zur Unterstützung von explorativen Suchprozessen im Speziellen dar. Ergänzend präsentierten Yvonne Jahns und Helga Karg von der Deutschen Nationalbibliothek den im MACSProjekt praktizierten Ansatz zur Verbindung von Indexierungsinstrumenten verschiedener Sprachen und das damit gegebene Potential zur Unterstützung eines multilingualen Retrievals. Die adäquate Modellierung von Dokumentationssprachen und Relationen zur Gewährleistung von Interoperabilität und Verbesserung von Suchfunktionalitäten bei heterogen erschlossenen Dokumentbeständen besonders in Hinblick auf Semantic-Web-Applikationen war Thema der zweiten Session. Jessica Hubrich von der Fachhochschule Köln nahm theoretische Ergebnisse des CrissCross-Projektes auf und stellte ein gestuftes Interoperabilitätsmodell vor, in dem Methoden zur Erstellung von Links zwischen Begriffen verschiedener Wissenssysteme in Bezug gesetzt wurden zu spezifischen Suchfunktionalitäten in Retrievalszenarien. Im anschließenden Vortrag von Claudia Effenberger und Julia Hauser von der Deutschen Nationalbibliothek wurde von den bisherigen Ergebnissen eines an der Deutschen Nationalbibliothek angesiedelten Forschungsprojekts berichtet, in dem jeder Klasse der Dewey-Dezimalklassifikation ein eindeutiger Identifier zugeordnet wird, durch den verschiedene Versionen einer Klasse unterschieden werden können. Dies dient der Verbesserung des Zugriffs auf bibliografische Titeldaten, die auf der Basis unterschiedlicher DDC-Versionen erschlossen wurden. Der erste Tag schloss mit einer Präsentation von Antoine Isaac von der Vrije Universiteit in Amsterdam ab. In dieser wurde Interoperabilität als Teil eines semantischen Netzes von Linked Data diskutiert und ein Überblick über zentrale Linked-Data-Projekte gegeben.
    Der zweite Tag begann mit einer Keynote von Dagobert Soergel von der University at Buffalo mit dem Thema Conceptual Foundations for Semantic Mapping and Semantic Search. Im Zentrum stand die Idee eines Hubs, einer semantischen Verbindungsstruktur in Form einer Kernklassifikation, die elementare Begriffe sowie semantische Relationen enthält und über die ein Mapping zwischen unterschiedlichen Wissensorganisationssystemen erfolgen soll. Die Methode wurde durch zahlreiche Beispiele veranschaulicht. Die erste Session des zweiten Tages war dem Thema Interoperabilität und Standardisierung gewidmet. Stella Dextre Clarke aus Großbritannien berichtete - ausgehend von den in zentralen Mappingprojekten erstellten Relationen zwischen Begriffen unterschiedlicher Dokumentationssprachen - über Herausforderungen und Fragestellungen bei der Entwicklung des neuen ISO-Standards 25964-2, der als Leitfaden zur Herstellung von Interoperabilität zwischen Thesauri und anderen Vokabularien fungieren soll. In dem Folgevortrag von Philipp Mayr vom GESIS Leipniz-Institut für Sozialwissenschaften wurd mit KoMoHe (Kompetenzzentrum Modellbildung und Heterogenitätsbehandlung) ein bereits abgeschlossenes Projekt vorgestellt, dessen Mehrwert für das Retrieval in heterogen erschlossenen Informationsräumen mittels eines Information-Retrieval-Tests bestätigt werden konnte. Unpräzise Trefferresultate motivierten indes zu dem Nachfolgeprojekt IRM (Value-Added Services for Information Retrieval), in dem Möglichkeiten von Suchexpansion und Re-Ranking untersucht werden.
