    Abstract
    In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

    Abstract
    The Hierarchical Interface to Library of Congress Classification (HILCC) is a system developed by the Columbia University Library to leverage call number data from the MARC holdings records in Columbia's online catalog to create a structured, hierarchical menuing system that provides subject access to the library's electronic resources. In this paper, the authors describe a research initiative at the Cornell University Library to discover if the Columbia HILCC scheme can be used as developed or in modified form to create a virtual undergraduate print collection outside the context of the traditional online catalog. Their results indicate that, with certain adjustments, an HILCC model can indeed, be used to represent the holdings of a large research library's undergraduate collection of approximately 150,000 titles, but that such a model is not infinitely scalable and may require a new approach to browsing such a large information space.

    Abstract
    Much literature has been written speculating upon how classification can be used in online catalogs to improve information retrieval. While some empirical studies have been done exploring whether the direct use of traditional classification schemes designed for a manual environment is effective and efficient in the online environment, none has manipulated these manual classifications in such a w ay as to take full advantage of the power of both the classification and computer. It has been suggested by some authors, such as Wajenberg and Drabenstott, that this power could be realized if the individual components of synthesized DDC numbers could be identified and indexed. This paper looks at the feasibility of automatically decomposing DDC synthesized numbers and the implications of such decomposition for information retrieval. Based on an analysis of the instructions for synthesizing numbers in the main class Arts (700) and all DDC Tables, 17 decomposition rules were defined, 13 covering the Add Notes and four the Standard Subdivisions. 1,701 DDC synthesized numbers were decomposed by a computer system called DND (Dewey Number Decomposer), developed by the author. From the 1,701 numbers, 600 were randomly selected fo r examination by three judges, each evaluating 200 numbers. The decomposition success rate was 100% and it was concluded that synthesized DDC numbers can be accurately decomposed automatically. The study has implications for information retrieval, expert systems for assigning DDC numbers, automatic indexing, switching language development, enhancing classifiers' work, teaching library school students, and providing quality control for DDC number assignments. These implications were explored using a prototype retrieval system.

    Footnote
    AHUJA and SATIJA (Relevance of Ranganathan's Classification Theory in the Age of Digital Libraries) note that traditional bibliographic classification systems have been applied in the digital environment with only limited success. They find that the "inherent flexibility of electronic manipulation of documents or their surrogates should allow a more organic approach to allocation of new subjects and appropriate linkages between subject hierarchies." (p. 18). Ahija and Satija also suggest that it is necessary to shift from a "subject" focus to a "need" focus when applying classification theory in the digital environment. They find Ranganathan's framework applicable in the digital environment. Although Ranganathan's focus is "subject oriented and hence emphasise the hierarchical and linear relationships" (p. 26), his framework "can be successfully adopted with certain modifications ... in the digital environment." (p. 26). SHAH and KUMAR (Model for System Unification of Geographical Schedules (Space Isolates)) report an a plan to develop a single schedule for geographical Subdivision that could be used across all classification systems. The authors argue that this is needed in order to facilitate interoperability in the digital environment. SAN SEGUNDO MANUEL (The Representation of Knowledge as a Symbolization of Productive Electronic Information) distills different approaches and definitions of the term "representation" as it relates to representation of knowledge in the library and information science literature and field. SHARADA (Linguistic and Document Classification: Paradigmatic Merger Possibilities) suggests the development of a universal indexing language. The foundation for the universal indexing language is Chomsky's Minimalist Program and Ranganathan's analytico-synthetic classification theory; Acording to the author, based an these approaches, it "should not be a problem" (p. 62) to develop a universal indexing language.
    Discussion The proceedings of the National Seminar an Classification in the Digital Environment give some insights. However, the depth of analysis and discussion is very uneven across the papers. Some of the papers have substantive research content while others appear to be notes used in the oral presentation. The treatments of the topics are very general in nature. Some papers have a very limited list of references while others have no bibliography. No index has been provided. The transfer of bibliographic knowledge organization theory to the digital environment is an important topic. However, as the papers at this conference have shown, it is also a difficult task. Of the 18 papers presented at this seminar an classification in the digital environment, only 4-5 papers actually deal directly with this important topic. The remaining papers deal with issues that are more or less relevant to classification in the digital environment without explicitly discussing the relation. The reason could be that the authors take up issues in knowledge organization that still need to be investigated and clarified before their application in the digital environment can be considered. Nonetheless, one wishes that the knowledge organization community would discuss the application of classification theory in the digital environment in greater detail. It is obvious from the comparisons of the classificatory structures of bibliographic classification systems and Web directories that these are different and that they probably should be different, since they serve different purposes. Interesting questions in the transformation of bibliographic classification theories to the digital environment are: "Given the existing principles in bibliographic knowledge organization, what are the optimum principles for organization of information, irrespectively of context?" and "What are the fundamental theoretical and practical principles for the construction of Web directories?" Unfortunately, the papers presented at this seminar do not attempt to answer or discuss these questions."

    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.
