    Abstract
    Unsere Welt ist voller Informationen. Diese werden seit jeher in eine systematische Ordnung gebracht. In der Geschichte der Wissensreprasentation spielen Bibliotheken und Bibliothekare eine grose Rolle. Bereits in der Antike gab es Kataloge. In der Bibliothek der Ptolemaer in Alexandria erarbeitete der Bibliothekar Kallimachos (ca. 305 . ca. 240 v.Chr.) die .Pinakes_g (Pinax: altgriechisch fur Tafel und Verzeichnis), die sehr wahrscheinlich gleichzeitig einen systematischen Katalog und eine Bibliographie verkorperten. Zusatzlich wurden die Dokumente rudimentar mittels eines vorgegebenen Ordnungssystems erschlossen und der Inhalt ruckte in den Mittelpunkt. Auch Philosophen hatten ihren Anteil an den Grundlagen der Wissensreprasentation. Aristoteles (384_]322 v.Chr.) arbeitete Kriterien aus, nach denen Begriffe voneinander zu differenzieren sind und nach denen Begriffe in eine hierarchische Ordnung gebracht werden. Das waren die Grundlagen fur Klassifikationen. Eine methodische Revolution erleben Klassifikationsforschung und .praxis mit der .Decimal Classification_g (1876) des amerikanischen Bibliothekars Melvil Dewey (1851_]1931). Die Grundidee der Klassifikation war einfach. Das Wissen wurde in maximal zehn Unterbegriffe unterteilt und durch Dezimalzeichen dargestellt. Die Aufstellung der Bucher in der Bibliothek folgte der Klassifikation, so dass thematisch verwandte Werke dicht beieinander standen. Die Dewey Dezimalklassifikation (DDC) wird auch heute noch haufig fur die inhaltliche Erschliesung genutzt und im Umkehrschluss um Dokumente aus einer Fulle von Informationen herausfinden zu konnen.

    Abstract
    Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

    Abstract
    This article reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The article discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and/or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the Dewey Decimal Classification [DDC] (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

    Abstract
    Purpose: To develop a prototype middleware framework between different terminology resources in order to provide a subject cross-browsing service for library portal systems. Design/methodology/approach: Nine terminology experts were interviewed to collect appropriate knowledge to support the development of a theoretical framework for the research. Based on this, a simplified software-based prototype system was constructed incorporating the knowledge acquired. The prototype involved mappings between the computer science schedule of the Dewey Decimal Classification (which acted as a spine) and two controlled vocabularies UKAT and ACM Computing Classification. Subsequently, six further experts in the field were invited to evaluate the prototype system and provide feedback to improve the framework. Findings: The major findings showed that given the large variety of terminology resources distributed on the web, the proposed middleware service is essential to integrate technically and semantically the different terminology resources in order to facilitate subject cross-browsing. A set of recommendations are also made outlining the important approaches and features that support such a cross browsing middleware service.

    "When dealing with a large-scale and widely-used knowledge organization system like the Dewey Decimal Classification, we often tend to focus solely on the organization aspect, which is closely intertwined with editorial work. This is perfectly understandable, since developing and updating the DDC, keeping up with current scientific developments, spotting new trends in both scholarly communication and popular publishing, and figuring out how to fit those patterns into the structure of the scheme are as intriguing as they are challenging. From the organization perspective, the intended user of the scheme is mainly the classifier. Dewey acts very much as a number-building engine, providing richly documented concepts to help with classification decisions. Since the Middle Ages, quasi-religious battles have been fought over the "valid" arrangement of places according to specific views of the world, as parodied by Jorge Luis Borges and others. Organizing knowledge has always been primarily an ontological activity; it is about putting the world into the classification. However, there is another side to this coin--the discovery side. While the hierarchical organization of the DDC establishes a default set of places and neighborhoods that is also visible in the physical manifestation of library shelves, this is just one set of relationships in the DDC. A KOS (Knowledge Organization System) becomes powerful by expressing those other relationships in a manner that not only collocates items in a physical place but in a knowledge space, and exposes those other relationships in ways beneficial and congenial to the unique perspective of an information seeker.
    What are those "other" relationships that Dewey possesses and that seem so important to surface? Firstly, there is the relationship of concepts to resources. Dewey has been used for a long time, and over 200,000 numbers are assigned to information resources each year and added to WorldCat by the Library of Congress and the German National Library alone. Secondly, we have relationships between concepts in the scheme itself. Dewey provides a rich set of non-hierarchical relations, indicating other relevant and related subjects across disciplinary boundaries. Thirdly, perhaps most importantly, there is the relationship between the same concepts across different languages. Dewey has been translated extensively, and current versions are available in French, German, Hebrew, Italian, Spanish, and Vietnamese. Briefer representations of the top-three levels (the DDC Summaries) are available in several languages in the DeweyBrowser. This multilingual nature of the scheme allows searchers to access a broader range of resources or to switch the language of--and thus localize--subject metadata seamlessly. MelvilClass, a Dewey front-end developed by the German National Library for the German translation, could be used as a common interface to the DDC in any language, as it is built upon the standard DDC data format. It is not hard to give an example of the basic terminology of a class pulled together in a multilingual way: <class/794.8> a skos:Concept ; skos:notation "794.8"^^ddc:notation ; skos:prefLabel "Computer games"@en ; skos:prefLabel "Computerspiele"@de ; skos:prefLabel "Jeux sur ordinateur"@fr ; skos:prefLabel "Juegos por computador"@es .
    Expressed in such manner, the Dewey number provides a language-independent representation of a Dewey concept, accompanied by language-dependent assertions about the concept. This information, identified by a URI, can be easily consumed by semantic web agents and used in various metadata scenarios. Fourthly, as we have seen, it is important to play well with others, i.e., establishing and maintaining relationships to other KOS and making the scheme available in different formats. As noted in the Dewey blog post "Tags and Dewey," since no single scheme is ever going to be the be-all, end-all solution for knowledge discovery, DDC concepts have been extensively mapped to other vocabularies and taxonomies, sometimes bridging them and acting as a backbone, sometimes using them as additional access vocabulary to be able to do more work "behind the scenes." To enable other applications and schemes to make use of those relationships, the full Dewey database is available in XML format; RDF-based formats and a web service are forthcoming. Pulling those relationships together under a common surface will be the next challenge going forward. In the semantic web community the concept of Linked Data (http://en.wikipedia.org/wiki/Linked_Data) currently receives some attention, with its emphasis on exposing and connecting data using technologies like URIs, HTTP and RDF to improve information discovery on the web. With its focus on relationships and discovery, it seems that Dewey will be well prepared to become part of this big linked data set. Now it is about putting the classification back into the world!"

    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.

    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.

    Abstract
    This paper explores the history, uses cases, and future plans associated with availability of the Dewey Decimal Classification (DDC) system as linked data. Parts of the Dewey Decimal Classification (DDC) system have been available as linked data since 2009. Initial efforts included the DDC Summaries (the top three levels of the DDC) in eleven languages exposed as linked data in dewey.info. In 2010, the content of dewey.info was further extended by the addition of assignable numbers and captions from the Abridged Edition 14 data files in English, Italian, and Vietnamese. During 2012, we will add assignable numbers and captions from the latest full edition database, DDC 23. In addition to the "old friends" of different Dewey language versions, institutions such as the British Library and Deutsche Nationalbibliothek have made use of Dewey linked data in bibliographic records and authority files, and AGROVOC has linked to our data at a general level. We expect to extend our linked data network shortly to "new acquaintances" such as GeoNames, ISO 639-3 language codes, and Mathematics Subject Classification. In particular, we will examine the linking process to GeoNames as an example of cross-domain vocabulary alignment. In addition to linking plans, we report on use cases that facilitate machine-assisted categorization and support discovery in the Semantic Web environment.

    Abstract
    Linked Open Data initiative has played a vital role in the realization of the Semantic Web at a global scale by publishing and interlinking diverse data sources on the Web. Access to this huge amount of Linked Data presents exciting benefits and opportunities. However, the inherent complexity attached to Linked Data understanding, lack of potential use cases and applications which can consume Linked Data hinders its full exploitation by naïve web users and developers. This book aims to address these core limitations of Linked Open Data and contributes by presenting: (i) Conceptual model for fundamental understanding of Linked Open Data sphere, (ii) Linked Data application to search, consume and aggregate various Linked Data resources, (iii) Semantification and interlinking technique for conversion of legacy data, and (iv) Potential application areas of Linked Open Data.

    Abstract
    Im Zuge zunehmender Globalisierung werden Wissensorganisationssysteme erforderlich, die ein sprachunabhängiges Retrieval ermöglichen, ohne dass dadurch bereits existierende und national bewährte Wissenssysteme obsolet werden. Das durch die Deutsche Forschungsgemeinschaft (DFG) geförderte und von der Deutschen Nationalbibliothek in Kooperation mit der Fachhochschule Köln durchgeführte Projekt CrissCross leistet einen wesentlichen Beitrag zur Schaffung eines solchen Wissensspeichers, indem es die Sachschlagwörter der deutschen Schlagwortnormdatei (SWD) mit Notationen der Dewey-Dezimalklassifikation sowie mit ihren Äquivalenten der Library of Congress Subject Headings (LCSH) und der französischen Schlagwortsprache RAMEAU (Repertoire d'autorité-matière encyclopédique et alphabétique unifié) verknüpft. Ein erweitertes multilinguales und thesaurusbasiertes Recherchevokabular wird erstellt, das für die inhaltliche Suche nach Dokumenten in heterogen erschlossenen Beständen verwendet werden kann. In diesem Artikel wird die Problematik bei der Verknüpfung semantisch heterogener Systeme unter besonderer Berücksichtigung der Unterschiede zwischen der DDC und der SWD skizziert. Die in CrissCross gewählte Methodik bei der Verknüpfung von SWD und DDC wird vorgestellt. Abschließend wird der Nutzen der erstellten Daten für das Retrieval aufgezeigt.

    "Last week, I received an email from Yulia Skora in Ukraine who is working on the mapping between UDC Summary and BBK (Bibliographic Library Classification) Summary. It reminded me of yet another challenging area of work. When responding to Yulia I realised that the issues with mapping, for instance, UDC Summary to Dewey Summaries [pdf] are often made more difficult because we have to deal with classification summaries in both systems and we cannot use a known exactMatch in many situations. In 2008, following advice received from colleagues in the HILT project, two of our colleagues quickly mapped 1000 classes of Dewey Summaries to UDC Master Reference File as a whole. This appeared to be relatively simple. The mapping in this case is simply an answer to a question "and how would you say e.g. Art metal work in UDC?" But when in 2009 we realised that we were going to release 2000 classes of UDC Summary as linked data, we decided to wait until we had our UDC Summary set defined and completed to be able to publish it mapped to the Dewey Summaries. As we arrived at this stage, little did we realise how much more complex the reversed mapping of UDC Summary to Dewey Summaries would turn out to be. Mapping the Dewey Summaries to UDC highlighted situations in which the logic and structure of two systems do not agree. Especially because Dewey tends to enumerate combinations of subject and attributes that do not always logically belong together. For instance, 850 Literatures of Italian, Sardinian, Dalmatian, Romanian, Rhaeto-Romanic languages Italian literature. This class mixes languages from three different subgroups of Romance languages. Italian and Sardinian belong to Italo Romance sub-family; Romanian and Dalmatian are Balkan Romance languages and Rhaeto Romance is the third subgroup that includes Friulian Ladin and Romanch. As UDC literature is based on a strict classification of language families, Dewey class 850 has to be mapped to 3 narrower UDC classes 821.131 Literature of Italo-Romance Languages , 821.132 Literature of Rhaeto-Romance languages and 821.135 Literature of Balkan-Romance Languages, or to a broader class 821.13 Literature of Romance languages. Hence we have to be sure that we have all these classes listed in the UDC Summary to be able to express UDC-DDC many-to-one, specific-to-broader relationships.
    Another challenge appears when, e.g., mapping Dewey class 890 Literatures of other specific languages and language families, which does not make sense in UDC in which all languages and literatures have equal status. Standard UDC schedules do not have a selection of preferred literatures and other literatures. In principle, UDC does not allow classes entitled 'others' which do not have defined semantic content. If entities are subdivided and there is no provision for an item outside the listed subclasses then this item is subsumed to a top class or a broader class where all unspecifiied or general members of that class may be expected. If specification is needed this can be divised by adding an alphabetical extension to the broader class. Here we have to find and list in the UDC Summary all literatures that are 'unpreferred' i.e. lumped in the 890 classes and map them again as many-to-one specific-to-broader match. The example below illustrates another interesting case. Classes Dewey 061 and UDC 06 cover roughy the same semantic field but in the subdivision the Dewey Summaries lists a combination of subject and place and as an enumerative classification, provides ready made numbers for combinations of place that are most common in an average (American?) library. This is a frequent approach in the schemes created with the physical book arrangement, i.e. library schelves, in mind. UDC, designed as an indexing language for information retrieval, keeps subject and place in separate tables and allows for any concept of place such as, e.g. (7) North America to be used in combination with any subject as these may coincide in documents. Thus combinations such as Newspapers in North America, or Organizations in North America would not be offered as ready made combinations. There is no selection of 'preferred' or 'most needed countries' or languages or cultures in the standard UDC edition: <Tabelle>
    If we map the Dewey Summaries to UDC in general and do not have to worry about a reverse relationship the situation is very simple as shown above. Mapping of UDC Summary to Dewey Summaries requires more thought. Firstly, UDC class (7) North America (common auxiliary of place) which simply represents the place has to be mapped to all occurences in which this place is 'built in' to the Dewey subjects: 063 Organization of North America 073 Journalism of North America 917 Geography of North America 970 History of North America 277 Christianity in North America 317 General Statistics in North America 557 Earth Sciences of North America The type of mapping from what is a general UDC concept of place (7) North America to a specific subject is clearly a broader-to-narrow match. Mapping of, for instance , UDC class 07 Newspapers. The press (includes journalism) to DDC class of 073 Journalim of North America is again broad-to-narrow match.
    Precombined subjects, such as those shown above from Dewey, may be expressed in UDC Summary as examples of combination within various records. To express an exact match UDC class 07 has to contain example of combination 07(7) Journals. The Press - North America. In some cases we have, therefore, added examples to UDC Summary that represent exact match to Dewey Summaries. It is unfortunate that DDC has so many classes on the top level that deal with a selection of countries or languages that are given a preferred status in the scheme, and repeating these preferences in examples of combinations of UDC emulates an unwelcome cultural bias which we have to balance out somehow. This brings us to another challenge.. UDC 913(7) Regional Geography - North America [contains 2 concepts each of which has its URI] is an exact match to Dewey 917 [represented as one concept, 1 URI]. It seems that, because they represent an exact match to Dewey numbers, these UDC examples of combinations may also need a separate URIs so that they can be published as SKOS data. Albeit challenging, mapping proves to be a very useful exercise and I am looking forward to future work here especially in relation to our plans to map UDC Summary to Colon Classification. We are discussing this project with colleagues from DRTC in Bangalore (India)."

    Abstract
    Purpose - The purpose of this paper is to provide a clear image of the information architecture used in the Encyclopedia of Iranian Architectural History (EIAH) and to show how it was crafted to meet the need for accessibility, expressiveness and interoperability. Design/methodology/approach - In order to assess the level of interoperability in the system, two essential concepts of the system are identified and traced in every level of the three-layer information architecture. Federated repositories are studied for the level of accessibility that they can offer. Knowledge representation level, mediator level and the semantic portal are studied for expressiveness capabilities. Findings - EIAH information architecture is capable of establishing links among resources available in the information pools connected to the system by using EIAH metadata application profile (EMAP). Different modules in this architecture, which are localized for the Persian language, can work on similar environments for other languages, for example Arabic. Originality/value - EIAH is the first example of a digital encyclopedia for the history of Iranian architecture, which is basically different from other digital encyclopedias in the way that it offers information to users. EIAH is aimed at domain experts and provides them not with pre-written and quality articles but with a wide range of resources and documents relative to what they are seeking.

    Abstract
    The compilation of terminological vocabularies plays a central role in the organization and retrieval of scientific texts. Both simple keyword lists as well as sophisticated modellings of relationships between terminological concepts can make a most valuable contribution to the analysis, classification, and finding of appropriate digital documents, either on the Web or within local repositories. This seems especially true for long-established scientific fields with various theoretical and historical branches, such as linguistics, where the use of terminology within documents from different origins is sometimes far from being consistent. In this short paper, we report on the early stages of a project that aims at the re-design of an existing domain-specific KOS for grammatical content grammis. In particular, we deal with the terminological part of grammis and present the state-of-the-art of this online resource as well as the key re-design principles. Further, we propose questions regarding ramifications of the Linked Open Data and Semantic Web approaches for our re-design decisions.

    Abstract
    For some years mapping has been one of the main tasks in the EDUG member countries. While the ISO standard on mapping and interoperability with other vocabularies (ISO 25964-2) gives some advice on creating mappings between a thesaurus and e.g. a classification system, it does not deal with Dewey Decimal Classification specifically. The EDUG members have felt a growing need to discuss and record the knowledge acquired in mapping projects where either the source or the target vocabulary is DDC. The recommendations below are the result of a seminar on mapping in connection with the EDUG annual meeting in April 2015. The recommendations are not exhaustive and will be subject to change as EDUG members gain more experience in this field of work. We still hope that institutions planning to embark on a mapping project to/from DDC, may find the guidelines helpful.
