    Abstract
    Am 19. und 20. Juli 2010 richten das Institut für Informationsmanagement (IIM) der Fachhochschule Köln und die Deutsche Nationalbibliothek (DNB) im Rahmen der Projekte CrissCross und RESEDA die Fachtagung Concepts in Context - Cologne Conference on Interoperability and Semantics in Knowledge Organization aus. Die Tagung findet in der Fachhochschule Köln statt und widmet sich Fragen der Interoperabilität und semantischer Informationen in der Wissensorganisation. Die Konferenz bietet Experten, Anwendern und Interessierten die Möglichkeit, verschiedene Modelle und Strategien der Wissensorganisation zu diskutieren und sich über neue Entwicklungen im Bereich der Standardisierung und Implementierung solcher Modelle zu informieren und auszutauschen. Der erste Tag ist als Abschlussworkshop für das DFG-Projekt CrissCross konzipiert und bietet neben einem umfassenden Überblick über das Projekt auch weitere praktische Anwendungsbeispiele für semantische Interoperabilität und mögliche Szenarien für ihre Anwendung in Online-Katalogen und im Rahmen des Semantic Web. Eine vertiefte Auseinandersetzung mit neueren Entwicklungen im Bereich der Interoperabilität unterschiedlicher Begriffssysteme sowie mit zukunftsträchtigen Modellen der semantischen Wissensorganisation findet am zweiten Tag statt. Aktuelle thematische Schwerpunkte werden hier die Functional Requirements for Bibliographic Records (FRBR) und die Functional Requirements for Subject Authority Data (FRSAD) sein. Zur Konferenz werden Informationsspezialisten aus mehreren Ländern erwartet.

    Abstract
    In this presentation, we therefore focus on a solution for providing uniform access to Digital Libraries and other online services. In order to enable uniform query access to heterogeneous sources, we must provide metadata interoperability in a way that a query language - in this case SPARQL - can cope with the incompatibility of the metadata in various sources without changing their already existing information models.

    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
    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
    This paper 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 paper 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 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
    Crosswalks between different vocabularies are an indispensable prerequisite for integrated and high quality search scenarios in distributed data environments. Offered through the web and linked with each other they act as a central link so that users can move back and forth between different data sources available online. In the past, crosswalks between different thesauri have primarily been developed manually. In the long run the intellectual updating of such crosswalks requires huge personnel expenses. Therefore, an integration of automatic matching procedures, as for example Ontology Matching Tools, seems an obvious need. On the basis of computer generated correspondences between the Thesaurus for Economics (STW) and the Thesaurus for the Social Sciences (TheSoz) our contribution will explore cross-border approaches between IT-assisted tools and procedures on the one hand and external quality measurements via domain experts on the other hand. The techniques that emerge enable semi-automatically performed vocabulary crosswalks.

    Abstract
    In this era of the Internet and distributed, multimedia computing, new and emerging classes of information systems applications have swept into the lives of office workers and people in general. From digital libraries, multimedia systems, geographic information systems, and collaborative computing to electronic commerce, virtual reality, and electronic video arts and games, these applications have created tremendous opportunities for information and computer science researchers and practitioners. As applications become more pervasive, pressing, and diverse, several well-known information retrieval (IR) problems have become even more urgent. Information overload, a result of the ease of information creation and transmission via the Internet and WWW, has become more troublesome (e.g., even stockbrokers and elementary school students, heavily exposed to various WWW search engines, are versed in such IR terminology as recall and precision). Significant variations in database formats and structures, the richness of information media (text, audio, and video), and an abundance of multilingual information content also have created severe information interoperability problems -- structural interoperability, media interoperability, and multilingual interoperability.

    Abstract
    This article provides an overview of the work carried out by the HILT Project <http://hilt.cdlr.strath.ac.uk> in making recommendations towards interoperable subject access, or cross-searching and browsing distributed services amongst the archives, libraries, museums and electronic services sectors. The article details consensus achieved at the 19 June 2001 HILT Workshop and discusses the HILT Stakeholder Survey. In 1999 Péter Jascó wrote that "savvy searchers" are asking for direction. Three years later the scenario he describes, that of searchers cross-searching databases where the subject vocabulary used in each case is different, still rings true. Jascó states that, in many cases, databases do not offer the necessary aids required to use the "preferred terms of the subject-controlled vocabulary". The databases to which Jascó refers are Dialog and DataStar. However, the situation he describes applies as well to the area that HILT is researching: that of cross-searching and browsing by subject across databases and catalogues in archives, libraries, museums and online information services. So how does a user access information on a particular subject when it is indexed across a multitude of services under different, but quite often similar, subject terms? Also, if experienced searchers are having problems, what about novice searchers? As information professionals, it is our role to investigate such problems and recommend solutions. Although there is no hard empirical evidence one way or another, HILT participants agree that the problem for users attempting to search across databases is real. There is a strong likelihood that users are disadvantaged by the use of different subject terminology combined with a multitude of different practices taking place within the archive, library, museums and online communities. Arguably, failure to address this problem of interoperability undermines the value of cross-searching and browsing facilities, and wastes public money because relevant resources are 'hidden' from searchers. HILT is charged with analysing this broad problem through qualitative methods, with the main aim of presenting a set of recommendations on how to make it easier to cross-search and browse distributed services. Because this is a very large problem composed of many strands, HILT recognizes that any proposed solutions must address a host of issues. Recommended solutions must be affordable, sustainable, politically acceptable, useful, future-proof and international in scope. It also became clear to the HILT team that progress toward finding solutions to the interoperability problem could only be achieved through direct dialogue with other parties keen to solve this problem, and that the problem was as much about consensus building as it was about finding a solution. This article describes how HILT approached the cross-searching problem; how it investigated the nature of the problem, detailing results from the HILT Stakeholder Survey; and how it achieved consensus through the recent HILT Workshop.

    Abstract
    Recently, a growing amount of systems that allow personal content annotation (tagging) are being created, ranging from personal sites for organising bookmarks (del.icio.us), photos (flickr.com) or videos (video.google.com, youtube.com) to systems for managing bibliographies for scientific research projects (citeulike.org, connotea.org). Simultaneously, a debate on the pro and cons of allowing users to add personal keywords to digital content has arisen. One recurrent point-of-discussion is whether tagging can solve the well-known vocabulary problem: In order to support successful retrieval in complex environments, it is necessary to index an object with a variety of aliases (cf. Furnas 1987). In this spirit, social tagging enhances the pool of rigid, traditional keywording by adding user-created retrieval vocabularies. Furthermore, tagging goes beyond simple personal content-based keywords by providing meta-keywords like funny or interesting that "identify qualities or characteristics" (Golder and Huberman 2006, Kipp and Campbell 2006, Kipp 2007, Feinberg 2006, Kroski 2005). Contrarily, tagging systems are claimed to lead to semantic difficulties that may hinder the precision and recall of tagging systems (e.g. the polysemy problem, cf. Marlow 2006, Lakoff 2005, Golder and Huberman 2006). Empirical research on social tagging is still rare and mostly from a computer linguistics or librarian point-of-view (Voß 2007) which focus either on the automatic statistical analyses of large data sets, or intellectually inspect single cases of tag usage: Some scientists studied the evolution of tag vocabularies and tag distribution in specific systems (Golder and Huberman 2006, Hammond 2005). Others concentrate on tagging behaviour and tagger characteristics in collaborative systems. (Hammond 2005, Kipp and Campbell 2007, Feinberg 2006, Sen 2006). However, little research has been conducted on the functional and linguistic characteristics of tags.1 An analysis of these patterns could show differences between user wording and conventional keywording. In order to provide a reasonable basis for comparison, a classification system for existing tags is needed.
