- Abstract
- This paper examines some traditional information searching methods and their role in Hungarian OPACs. What challenges are there in the digital and online environment? How do users work with them and do they give users satisfactory results? What kinds of techniques are users employing? In this paper I examine the user interfaces of UDC, thesauri, subject headings etc. in the Hungarian library. The key question of the paper is whether a universal system or local solutions is the best approach for searching in the digital environment.

- "Am 16. August 2005 fand in Oslo im Rahmen der heurigen IFLA-Konferenz das alljährliche Treffen der DDC-Übersetzer und der weltweiten DeweyAnwender-Institutionen (Nationalbibliotheken, Ersteller von Nationalbibliografien) statt. Die im Sommer 2005 bereits abgeschlossene deutsche Übersetzung wird in der Druckfassung Ende des Jahres in 4 Bänden vorliegen, beim K. G. Saur Verlag in München erscheinen (ISBN 3-598-11651-9) und 2006 vom ebenfalls erstmals ins Deutsche übersetzten DDC-Lehrbuch (ISBN 3-598-11748-5) begleitet. Pläne für neu startende Übersetzungen der DDC 22 gibt es für folgende Sprachen: Arabisch (mit der wachsenden Notwendigkeit, Klasse 200 Religion zu revidieren), Französisch (es erschien zuletzt eine neue Kurzausgabe 14, nun werden eine vierbändige Druckausgabe und eine frz. Webversion anvisiert), Schwedisch, Vietnamesisch (hierfür wird eine an die Sprache und Schrift angepasste Version des deutschen Übersetzungstools zum Einsatz kommen).
Das Neueste zuerst Die Herausgeber der DDC präsentierten eine neue Informationsplattform "025.431: The Dewey blog"; seit Anfang Juli erreichbar unter http://ddc.typepad.com/. Neu ist auch der fünfsprachige, mit einem Farbleitsystem ausgestattete "DeweyBrowser" von OCLC; der Protoyp führt bereits in einen Katalog von 125.000 e-books und kann unter http://ddcresearch.oclc.org ,i ebooks/fileServer erprobt werden. OCLC bietet seit April 2005 eine neue Current Awareness-Schiene zur DDC mit unterschiedlichen Schwerpunkten an: Dewey Mappings, Dewey News, DeweyTips, Dewey Updates, Deweyjournal (letzteres fängt Themen aus allen 4 Teilbereichen auf); zu subskribieren unter http://www.oclc.org/dewey/syndicated/rss.htm. Wichtig für Freihandaufstellungen Die Segmentierung von Dewey-Notationen wurde reduziert! Ab September 2005 vergibt LoC nur noch ein einziges Segmentierungszeichen, und zwar an der Stelle, an der die jeweilige Notation in der englischen Kurzausgabe endet. Der Beginn einer Teilnotation aus Hilfstafel 1: Standardunterteilungen, wird also nun nicht mehr markiert. Für die Bildung von Standortsignaturen bietet sich das Dewey Cutter Programm an; Downloaden unter www.oclc.org/dewey/support/program.
Allgemein DDC 22 ist im Gegensatz zu den früheren Neuauflagen der Standard Edition eine Ausgabe ohne generelle Überarbeitung einer gesamten Klasse. Sie enthält jedoch zahlreiche Änderungen und Expansionen in fast allen Disziplinen und in vielen Hilfstafeln. Es erschien auch eine Sonderausgabe der Klasse 200, Religion. In der aktuellen Kurzausgabe der DDC 22 (14, aus 2004) sind all diese Neuerungen berücksichtigt. Auch die elektronische Version exisitiert in einer vollständigen (WebDewey) und in einer KurzVariante (Abridged WebDewey) und ist immer auf dem jüngsten Stand der Klassifikation. Ein Tutorial für die Nutzung von WebDewey steht unter www.oclc.org /dewey/ resourcesitutorial zur Verfügung. Der Index enthält in dieser elektronischen Fassung weit mehr zusammengesetzte Notationen und verbale Sucheinstiege (resultierend aus den Titeldaten des "WorldCat") als die Druckausgabe, sowie Mappings zu den aktuellsten Normdatensätzen aus LCSH und McSH. Aktuell Die personelle Zusammensetzung des EPC (Editorial Policy Committee) hat sich im letzten Jahr verändert. Dieses oberste Gremium der DDC hat Prioritäten für den aktuellen Arbeitsplan festgelegt. Es wurde vereinbart, größere Änderungsvorhaben via Dewey-Website künftig wie in einem Stellungnahmeverfahren zur fachlichen Diskussion zu stellen. www.oclc.org/dewey/discussion/."

- Abstract
- The concept of c-space is proposed as a visualization schema relating containers of content to cataloging surrogates and classification structures. Possible applications of keyword vector clusters within c-space could include improved retrieval rates through the use of captioning within visual hierarchies, tracings of semantic bleeding among subclasses, and access to buried knowledge within subject-neutral publication containers. The Scholastica Project is described as one example, following a tradition of research dating back to the 1980's. Preliminary focus group assessment indicates that this type of classification rendering may offer digital library searchers enriched entry strategies and an expanded range of re-entry vocabularies. Those of us who work in traditional libraries typically assume that our systems of classification: Library of Congress Classification (LCC) and Dewey Decimal Classification (DDC), are descriptive rather than prescriptive. In other words, LCC classes and subclasses approximate natural groupings of texts that reflect an underlying order of knowledge, rather than arbitrary categories prescribed by librarians to facilitate efficient shelving. Philosophical support for this assumption has traditionally been found in a number of places, from the archetypal tree of knowledge, to Aristotelian categories, to the concept of discursive formations proposed by Michel Foucault. Gary P. Radford has elegantly described an encounter with Foucault's discursive formations in the traditional library setting: "Just by looking at the titles on the spines, you can see how the books cluster together...You can identify those books that seem to form the heart of the discursive formation and those books that reside on the margins. Moving along the shelves, you see those books that tend to bleed over into other classifications and that straddle multiple discursive formations. You can physically and sensually experience...those points that feel like state borders or national boundaries, those points where one subject ends and another begins, or those magical places where one subject has morphed into another..."
But what happens to this awareness in a digital library? Can discursive formations be represented in cyberspace, perhaps through diagrams in a visualization interface? And would such a schema be helpful to a digital library user? To approach this question, it is worth taking a moment to reconsider what Radford is looking at. First, he looks at titles to see how the books cluster. To illustrate, I scanned one hundred books on the shelves of a college library under subclass HT 101-395, defined by the LCC subclass caption as Urban groups. The City. Urban sociology. Of the first 100 titles in this sequence, fifty included the word "urban" or variants (e.g. "urbanization"). Another thirty-five used the word "city" or variants. These keywords appear to mark their titles as the heart of this discursive formation. The scattering of titles not using "urban" or "city" used related terms such as "town," "community," or in one case "skyscrapers." So we immediately see some empirical correlation between keywords and classification. But we also see a problem with the commonly used search technique of title-keyword. A student interested in urban studies will want to know about this entire subclass, and may wish to browse every title available therein. A title-keyword search on "urban" will retrieve only half of the titles, while a search on "city" will retrieve just over a third. There will be no overlap, since no titles in this sample contain both words. The only place where both words appear in a common string is in the LCC subclass caption, but captions are not typically indexed in library Online Public Access Catalogs (OPACs). In a traditional library, this problem is mitigated when the student goes to the shelf looking for any one of the books and suddenly discovers a much wider selection than the keyword search had led him to expect. But in a digital library, the issue of non-retrieval can be more problematic, as studies have indicated. Micco and Popp reported that, in a study funded partly by the U.S. Department of Education, 65 of 73 unskilled users searching for material on U.S./Soviet foreign relations found some material but never realized they had missed a large percentage of what was in the database.

- Abstract
- The term "facet" has been used in various places, while in most cases it is just a buzz word to replace what is indeed "aspect" or "category". The references below either define and explain the original concept of facet or provide guidelines for building 'real' faceted search/browse. I was interested in faceted classification because it seems to be a natural and efficient way for organizing and browsing Web collections. However, to automatically generate facets and their isolates is extremely difficult since it involves concept extraction and concept grouping, both of which are difficult problems by themselves. And it is almost impossible to achieve mutually exclusive and jointly exhaustive 'true' facets without human judgment. Nowadays, faceted search/browse widely exists, implicitly or explicitly, on a majority of retail websites due to the multi-aspects nature of the data. However, it is still rarely seen on any digital library sites. (I could be wrong since I haven't kept myself updated with this field for a while.)
