Outsourcing Information Services
Get PDFPurpose: The systematic redevelopment of a Corporate Information Center's strategy is presented in this case study, with particular focus on the aspect of outsourcing services. This aspect is emphasised, because it is the only way to realise a new business model without an increase in resources.
Design/methodology/approach: There is a description of which services have been outsourced, while it is also made clear which activities related to the creation of processes and their supervision have remained in the company's internal Information Center, and how they are changing as time goes on. The licensing of information sources from external aggregators is viewed in the context of outsourcing, as is the latest development in Vendor Portfolio Management.
Findings: After the transformation of the classic spectrum of library services into the strategically created portfolio of an Online Information Center, the core tasks at the forefront are those which anchor the Information Center in the corporation of which it is a part, and which perfectly combine the interests of the corporation with the use of information industry competencies through cooperation and partnership with service providers.
Originality / value: This case study demonstrates how, and for what purpose, information industry competencies can be used in an Online Information Center. Even with limited resources, the skilful use of outsourcing solutions makes possible the redevelopment of strategy and therefore change
Enhancing document modeling by means of open topic models Crossing the frontier of classification schemes in digital libraries by example of the DDC
Get PDFPurpose: We present a topic classification model using the Dewey Decimal Classification (DDC) as the target scheme. This is done by exploring metadata as provided by the Open Archives Initiative (OAI) to derive document snippets as minimal document representations. The reason is to reduce the effort of document processing in digital libraries. Further, we perform feature selection and extension by means of social ontologies and related web-based lexical resources. This is done to provide reliable topic-related classifications while circumventing the problem of data sparseness. Finally, we evaluate our model by means of two language-specific corpora. This paper bridges digital libraries on the one hand and computational linguistics on the other. The aim is to make accessible computational linguistic methods to provide thematic classifications in digital libraries based on closed topic models as the DDC.
Design/methodology/approach: text classification, text-technology, computational linguistics, computational semantics, social semantics.
Findings: We show that SVM-based classifiers perform best by exploring certain selections of OAI document metadata.
Research limitations/implications: The findings show that it is necessary to further develop SVM-based DDC-classifiers by using larger training sets possibly for more than two languages in order to get better F-measure values.
Practical implications: We can show that DDC-classifications come into reach which primarily explore OAI metadata.
Originality/value:
We provide algorithmic and formal-mathematical information how to build DDC-classifiers for digital libraries
Tagging and Automation : Challenges and Opportunities for Academic Libraries
Get PDFPurpose: comparing and examining the quality of the results of tagging, intellectual and automated indexing processes.
Design/methodology/approach: analysis and graphical representation of annotation sets using the software "Semtinel".
Findings: a combination of tagging, intellectual and automatic indexing is probably best suited to shape the annotation of literature more efficiently without compromising quality.
Research limitations/implications: exploratory study on the base of three journals.
Originality/value: the paper presents the open source software Semtinel offering a highly optimized toolbox for analysing thesauri and classifications
Publikationslisten als hochschulweiter Dienst: das DFG Projekt "PubLister"
No full textPersönliche Publikationslisten sind ein wichtiges Informationsmittel für die Wissenschaftskommunikation. Zur Entwicklung und Erprobung nachhaltiger Dienste für die Gestaltung der Publikationsliste im Internet fördert die Deutsche Forschungsgemeinschaft (DFG) für zwei Jahre das an der Universität Bielefeld angesiedelte Projekt "Persönliche Publikationslisten als hochschulweiter Dienst" (PubLister) . PubLister schafft einen organisatorischen und technischen Rahmen für ein einheitliches Publikationsmanagement an Hochschulen. Exemplarisch für die Universität Bielefeld untersucht das Projekt Strategien, wie bibliothekarische Dienste Wissenschaftler möglichst gut bei der Erstellung und Pflege ihrer Publikationslisten unterstützen können. Literatur: Jahn, N. & Horstmann, W. (Preprint). Persönliche Publikationslisten als hochschulweiter Dienst : Eine Bestandsaufnahme
An integrated digital research environment: DFG perspectives
Get PDFPurpose: The article focuses on the vision that the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG) pursues with its funding programmes in the field of digital information provision.
Design/methodology/approach: The first section of the article sketches out the strategic decisions which determine the funding policy of the DFG in the field of digital information, while the second section describes in more detail the central funding schemes of the DFG in the field of digital information.
Findings: The funding policy of the DFG seeks to build an integrated digital research environment that includes scholarly publications and primary research data as well as new forms of communication in virtual research and work environments. But it will be only by the common effort of scholars, libraries and providers of scholarly information, funders, publishers and fee collecting agencies that the vision of an integrated digital research environment will come true.
Originality / value: The outline of the funding programmes of the DFG in the area of digital information provision will be of interest to librarians and information professionals seeking information about library funding policies and strategies in Germany
The Knowledge Portal, or, the Vision of Easy Access to Information
Get PDFPurpose: The development of the 'Knowledge Portal' is the attempt to develop a central access system in terms of a 'single point of access' for all electronic information services. This means that all these sources - from the library's catalogue and full-text in-house applications to external, licensed sources - should be accessible via one central Web service.
Design/methodology/approach: The Knowledge Portal is a piece of software and a real library application, based on Primo, a commercial product, which has been enhanced through a cooperative project from ETH Libraries (Libraries of the Swiss Federal Institute of Technology Zurich) and ExLibris. The new portal will be the result of integrating this new metasearch and the library's homepage.
Findings: The paper gives an overview of the general idea behind this complex and clearly user-oriented project and shows which steps are necessary for its launch.
Originality / value: The paper gives an example of how to organize cooperation between quite different project partners and shows the complexity of setting up a portal as the single point of access
Automatische Klassifizierung von Metadaten mit linguistischen Methoden, DFG-Projekt
No full textDie Recherche nach Fachinformation in elektronischen Informationssystemen ist aus Wissenschaft und Forschung nicht mehr wegzudenken. Die Qualität der Sacherschließungsinformationen in diesen Systemen ist dabei von entscheidender Bedeutung. Techniken wie etwa semantische Suche oder semantisches Browsing können nur mit standardisierter Erschließung realisiert werden. Der Vortrag behandelt die Normalisierung von Sacherschließungsinformationen in OAI-Metadaten durch automatische Klassifikation nach der Dewey Decimal Classification (DDC). Nach einem Überblick über Motivation, Ist-Zustand und Projektziele wird das Klassifikationsverfahren erläutert und ein Ausblick auf die weiteren Projektaktivitäten gegeben
Maschinelles Lernen und semantische Visualisierung - ein Beispiel zur Analyse von Nutzerfragen aus einem Verbraucherschutzforum
No full textInternet-Foren sind allgegenwärtig. Menschen diskutieren online über neueste Nachrichten, die Eigenschaften neuer Digitalkameras oder fragen nach Ernährungstipps. Die Daten sind häufig online verfügbar, in den meisten Fällen jedoch völlig unstrukturiert. Eine Analyse oder Online-Monitoring gestaltet sich schwierig. Im Vortrag wird ein maschinelles Lernverfahren vorgestellt, mit dessen Hilfe große Mengen unstrukturierter Daten nach dem Prinzip der Selbsorganisation so geordnet werden können, dass eine semantische Visualiserung Einblicke in die Zusammenhänge der Daten erlaubt. Das Verfahren wird z.Zt. in Kooperation mit dem aid infodienst, einem vom Bundesministerium für Ernährung, Landwirtschaft und Verbraucherschutz gefördertem e.V. angewendet. Beispiele aus der Praxis verdeutlichen den Einsatz des Systems
Upgrading Academic Scholarship : Challenges and Chances of the Digital Age
Get PDFPurpose: The paper is a discussion of what the beginning of the Internet Age means for the functions and structures of scholarly information and communication by looking at and evaluating today's usability and usage of the digital information infrastructure for and by academic scholarship.
Design/methodology/approach: The paper gives an overview of the current state of development of digital information in the scholarly cultures and stresses the importance of data as the crucial - and considerably extended - basis of scholarly work. The central role of the publishing world for the academic rewards system is analyzed to consider continuities and discontinuities in scholarly publication.
Findings: The paper advances the thesis first coined by Christine Borgman that today we have an information infrastructure of, but not one for scholarly information. Some ideas and proposals of what should be done to move towards an information infrastructure for scholarly work conclude the paper.
Originality/value: The paper tries to bridge the gap between information professionals as producers and scholars as users of information and communication technologies and shows that a joint debate on these issues is necessary
