    Abstract
    Retrieval Tests sind die anerkannteste Methode, um neue Verfahren der Inhaltserschließung gegenüber traditionellen Verfahren zu rechtfertigen. Im Rahmen einer Diplomarbeit wurden zwei grundsätzlich unterschiedliche Systeme der automatischen inhaltlichen Erschließung anhand der Pressedatenbank des Verlagshauses Gruner + Jahr (G+J) getestet und evaluiert. Untersucht wurde dabei natürlichsprachliches Retrieval im Vergleich zu Booleschem Retrieval. Bei den beiden Systemen handelt es sich zum einen um Autonomy von Autonomy Inc. und DocCat, das von IBM an die Datenbankstruktur der G+J Pressedatenbank angepasst wurde. Ersteres ist ein auf natürlichsprachlichem Retrieval basierendes, probabilistisches System. DocCat demgegenüber basiert auf Booleschem Retrieval und ist ein lernendes System, das auf Grund einer intellektuell erstellten Trainingsvorlage indexiert. Methodisch geht die Evaluation vom realen Anwendungskontext der Textdokumentation von G+J aus. Die Tests werden sowohl unter statistischen wie auch qualitativen Gesichtspunkten bewertet. Ein Ergebnis der Tests ist, dass DocCat einige Mängel gegenüber der intellektuellen Inhaltserschließung aufweist, die noch behoben werden müssen, während das natürlichsprachliche Retrieval von Autonomy in diesem Rahmen und für die speziellen Anforderungen der G+J Textdokumentation so nicht einsetzbar ist

    Abstract
    Does contemporary Internet technology strengthen civic engagement and democratic practice? The recent surge in online community participation has become a cultural phenomenon enmeshed in ongoing debates about the health of American civil society. But observations about online communities often concentrate on ascertaining the true nature of community and democracy, typically rehearsing familiar communitarian and liberal perspectives. This book seeks to understand the technology on its own terms, focusing on how the technological and organizational configurations of online communities frame our contemporary beliefs and assumptions about community and the individual. It analyzes key structural features of thirty award-winning online community websites to show that while the values of individual autonomy, egalitarianism, and freedom of speech dominate the discursive content of these communities, the practical realities of online life are clearly marked by exclusivity and the demands of commercialization and corporate surveillance. Promises of social empowerment are framed within consumer and therapeutic frameworks that undermine their democratic efficacy. As a result, online communities fail to revolutionize the civic landscape because they create cultures of membership that epitomize the commodification of community and public life altogether.

    Abstract
    Autonomy of operations combined with decentralized management of data gives rise to a number of hetegrogeneous databases or information systems within an enterprise. These systems are often incompatible in structure as well as content and, hence, difficult to integrate. Depsite heterogeneity, the unity of overall purpose within a common application domain, nevertheless, provides a degree of semantic similarity that manifests itself in the form of similar data structures and common usage patterns of existing information systems. This article introduces a conceptual integration approach that exploits the similarity in metalevel information in existing systems and performs 'metadata mining' on database objects to discover a set of concepts that serve as a domain abstraction and provide a conceptual layer is further uitlized by an information reengineering framework that customizes and packages information to reflect the unique needs of differnt user groups within the application domain. The architecture of the information reengineering framework is based on an object-oriented model that represents the discovered concepts as customized application objects for each distinct user group

    Abstract
    The aim of this article is to contribute to the development of the domain analytical approach by using tools from the theory of professions. This is accomplished by showing how the symbolic values of professional information can create, sustain, and alter professional interests, power relations, and occupational identities. By taking this approach, the importance of considering the issues of power and knowledge use as a social practice is highlighted - two themes that only to a certain extent have been attended to within domain analysis. The aim is accomplished through a study of nursing literature that reveals how Professional information is regarded within the Swedish nursing profession. These are analyzed in relation to changes and development within the profession's applied knowledge domain over time. It is argued that the knowledge domain of nursing has shifted from a primarily practical orientation towards an increasingly theoretical orientation. Its previous subordination to medical expertise has been replaced by an aspiration towards professional autonomy. This shift is seen as a result of a professional strategy where the specialist literature, libraries and databases of the occupational community play an important symbolic role.

    Abstract
    Graz University of Technology (TUG), which was founded in 1811, has gained some reputation for its competence in research & development. In its previous version, TUG's web-based online CRIS (www.tugraz.at/research) started in 1997, including a freely accessible documentation of ongoing and completed research activities, combined with the lists of scientific publications originating from such activities. It proved to be highly sufficient as long the university was mainly interested, within this framework, in the transfer of knowledge and technology, as well as in the scientific co-operation with partners, both in industry and in academia. Recently, however, an additional aspect has become more important in research policies: the analysis and evaluation of scientific impact, based an bibliometric tools. As a result, the documentation of scientific publications now requires a higher level of data quality than before, when it was sufficient to inform one's peers in the field. In this paper, TUG's newly developed documentation of scientific publications is presented. It satisfies more demanding expectations inside an increasingly competitive academic world. But we had to keep in mind the financial limits of a university which is about to leave the safe harbour of civil service and govemment administration, and is bound to the challenging seas of academic autonomy.

    Abstract
    Classifying wsith Dewey Decimal Classification (Editions 19 and 20) is a pathfinder for those who have problems in practical application of DDC and for those who are eager to reclassify their documents from Edition 19 to 20. It highlights the difference between Edition 19 and 20 and the new features in the Edition 20. The book has simplified the practical application and number building procedure by providing systematic and stepwise guidance. It vividly explains the way add device is applied, the working of seven tables and special tables and the classes where the classifier has the autonomy to assign class numbers to specific documents as per local needs of the library. The book is so planned that it helps in understanding easily the nuances of both the editions of DDC. Accordingly it is useful for library community in general and students, teachers and classifiers in particular.

    Abstract
    This paper aims to investigate whether academic reference librarians, archivists, catalogers, distance education librarians, public librarians, records managers, school librarians, special collections librarians, and systems librarians differ in personality traits measured by the Personal Style Inventory: i.e. adaptability, assertiveness, autonomy, conscientiousness, customer service orientation, emotional resilience, extraversion, openness, optimism, teamwork, tough-mindedness, visionary/operational work style, and work drive. It also aims to investigate whether personality traits of those in person-oriented library specialties differ from those in technique-oriented (technical) library specialties. Design/methodology/approach - A total of 2,075 librarians/information professionals were surveyed in non-random sample. The Personal Style Inventory is a normal personality inventory assessing important traits for the world of work. It was used in a two-step cluster analysis for the data analysis. Findings - The paper finds that distinct personality traits were associated with the different types of librarians. There was also a "unadaptive" cluster composed of individuals from all specialties. There were distinguishing traits associated with person-oriented and technique-oriented specialties. Research limitations/implications - Results were not generalizable due to the non-random sample. Gender was not collected. The research has implications for career counseling. Originality/value - There have been few studies of personality traits in library specialties, none measuring both narrow work trait and broad personality trait variables.

    Abstract
    In this paper we examine how information - particularly, its organization and presentation - and space (i.e., a physical location) can be combined to create a particular place (i.e., a location adapted to a particular purpose) for engaging and stabilizing homeless young people, aged 13-25. Over 10 months, we used a participatory-design research approach to investigate how an alliance of nine service agencies used information resources to support homeless young people. We collected 250 information resources and analyzed how these materials were organized and presented at four service agencies. In general, the agencies used ad hoc organizational schemes and presentations that were not in keeping with the key values of the alliance, which include human welfare, respect, trust, autonomy, and sustainability. To improve information delivery and the projection of common values, we followed a two-step design process. First, based on a card-sorting activity, we developed a new organizational scheme. Second, we developed four interrelated prototypes for presenting information resources: Rolling Case, InfoBike, Slat Wall, and Infold. To convey the use of these prototypes, three short video scenarios were created to demonstrate how the prototypes would be used by stakeholders, including homeless young people, staff, and volunteers. Feedback from stakeholders suggested that these prototypes, when sufficiently refined, could be useful and operationally viable. By investigating the concept of place, reconstituted through organizational schemes and novel presentations of information resources, this work creates possibilities that may allow grassroots service agencies to give more efficient access to information while expressing their values.
