    Abstract
    Informationsdienste werden heutzutage von großen Teilen der Bevölkerung im Berufs- wie im Privatleben genutzt. Es ist ein wichtiges informationswissenschaftliches Thema, Informationsdienste adäquat zu beschreiben und ihre Qualität zu bewerten. Unser Information Service Evaluation (ISE) Modell führt unterschiedliche Traditionen der Evaluations- sowie der Technologieakzeptanzforschung zusammen und besteht aus fünf Dimensionen: Qualität des Informationsdienstes, Nutzer, Informationsakzeptanz, Informationsumfeld und Zeit. Der Überblicks­artikel erläutert diese Dimension und bietet einen Einblick in ein flexibel handhabbares und umfassendes holistisches Modell der Beschreibung und Bewertung von Informationsdiensten.

    Abstract
    Was hat Information mit Mobilität zu tun? Nun, zunächst kann Information Mobilität unterstützen, Fahrerinformationssysteme sind ein bekanntes Beispiel. Information kann darüber hinaus unnötige Mobilität vermeiden helfen, indem die Information mobil wird und seinen Empfänger ortsungebunden findet. Die ' "ubiquitäre" Information erreicht den Außendienstmitarbeiter fern vom Back Office, den Studenten fern von der Hochschule oder einen Kollegen in seinem Home Office fern vom Standort der Firma. Information kann auch zu mehr Mobilität führen, denken wir nur an Lieferungen im Anschluss an Bestellungen im E-Commerce. (Dieser Aspekt wird allerdings in Regensburg nicht angesprochen). Letztendlich muss auch die "geistige Mobilität" beim Lehren und Lernen mit den neuen digitalen Medien genannt werden, eine Mobilität, die sich eher im Hintergrund abspielt, die aber einer 'stillen Revolution" gleichkommt. Das Generalthema "Information und Mobilität" des achten Internationalen Symposiums für Informationswissenschaft (ISI) wurde nicht zufällig beim diesjährigen Tagungsort in Regensburg gewählt, denn an der Universität Regensburg existiert seit Jahren ein interdisziplinäres Forschungszentrum für Information und Mobilität. Außerhalb des Generalthemas bringt das ISI - wie gewohnt - ein zusätzliches Spektrum informationswissenschaftlicher Themen und - auch wie gewohnt - mit dem "Best Student Paper Award" den Wettbewerb um die beste studentische Leistung der letzten zwei Jahre - diesmal mit einem Sieger und mit einem Sonderpreis. Fahrerinformationssysteme: akustische und/oder visuelle Metainformationen?

    Abstract
    Informational cities are prototypical cities of the knowledge society. If they are informational world cities, they are new centers of power. According to Manuel Castells (1989), in those cities space of flows (flows of money, power, and information) tend to override space of places. Information and communication technology infrastructures, cognitive infrastructures (as groundwork of knowledge cities and creative cities), and city-level knowledge management are of great importance. Digital libraries provide access to the global explicit knowledge. The informational city consists of creative clusters and spaces for personal contacts to stimulate sharing of implicit information. In such cities, we can observe job polarization in favor of well-trained employees. The corporate structure of informational cities is made up of financial services, knowledge-intensive high-tech industrial enterprises, companies of the information economy, and further creative and knowledge-intensive service enterprises. Weak location factors are facilities for culture, recreational activities, and consumption. Political willingness to create an informational city and e-governance activities are crucial aspects for the development of such cities. This conceptual article frames indicators which are able to mark the degree of "informativeness" of a city. Finally, based upon findings of network economy, we try to explain why certain cities master the transition to informational cities and others (lagging to relative insignificance) do not. The article connects findings of information science and of urbanistics and urban planning.

    Abstract
    Purpose - Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document-specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems. Design/methodology/approach - In a theoretical approach the paper discusses document-specific tag distributions (power law and inverse-logistic shape), the development of such distributions (Yule-Simon process and shuffling theory) and introduces search tags (besides the well-known index tags) as a possibility for generating tag distributions. Findings - Search tags are compatible with broad and narrow folksonomies and with all knowledge organization systems (e.g. classification systems and thesauri), while index tags are only applicable in broad folksonomies. Based on these findings, the paper presents a sketch of an algorithm for mining and processing power tags in information retrieval systems. Research limitations/implications - This conceptual approach is in need of empirical evaluation in a concrete retrieval system. Practical implications - Power tags are a new search option for retrieval systems to limit the amount of hits. Originality/value - The paper introduces power tags as a means for enhancing the precision of search results in information retrieval systems that apply folksonomies, e.g. catalogs in Library 2.0environments.

    Abstract
    Concept-based information retrieval and knowledge representation are in need of a theory of concepts and semantic relations. Guidelines for the construction and maintenance of knowledge organization systems (KOS) (such as ANSI/NISO Z39.19-2005 in the U.S.A. or DIN 2331:1980 in Germany) do not consider results of concept theory and theory of relations to the full extent. They are not able to unify the currently different worlds of traditional controlled vocabularies, of the social web (tagging and folksonomies) and of the semantic web (ontologies). Concept definitions as well as semantic relations are based on epistemological theories (empiricism, rationalism, hermeneutics, pragmatism, and critical theory). A concept is determined via its intension and extension as well as by definition. We will meet the problem of vagueness by introducing prototypes. Some important definitions are concept explanations (after Aristotle) and the definition of family resemblances (in the sense of Wittgenstein). We will model concepts as frames (according to Barsalou). The most important paradigmatic relation in KOS is hierarchy, which must be arranged into different classes: Hyponymy consists of taxonomy and simple hyponymy, meronymy consists of many different part-whole-relations. For practical application purposes, the transitivity of the given relation is very important. Unspecific associative relations are of little help to our focused applications and should be replaced by generalizable and domain-specific relations. We will discuss the reflexivity, symmetry, and transitivity of paradigmatic relations as well as the appearance of specific semantic relations in the different kinds of KOS (folksonomies, nomenclatures, classification systems, thesauri, and ontologies). Finally, we will pick out KOS as a central theme of the Semantic Web.

    Abstract
    Seit 1983 gibt es die Arbeitsgemeinschaft Informationsvermittlung (AGI). Die AGI-Information Management Consultants, vorneweg Manfred Hauer, sind inzwischen ausgewiesene Spezialisten bei der Anwendung von Information Retrieval-Systemen. Seit 1994 bietet M. Hauer ein umfassendes Produkt an, das INFORMATION CENTER, das u.a. Elemente der Bibliotheksverwaltung, der Pressedokumentation, der Recherche, der Adreßverwaltung und des Publizierens miteinander verbindet. Durch den aktuellen Umstieg der Basis-Software, Lotus, auf die neue IBM-Suchmaschine GTR hat eine Betrachtung von INFORMATION CENTER besondere Relevanz, erreichen wir doch nunmehr einen Bereich, der von Informatikern und Beratern mit 'Knowledge Management' umschrieben wird. Damit wäre INFORMATION CENTER das erste deutsche Knowledge Management-Produkt auf einer umfassenden informationswissenschaftlichen Basis. Wird es einem solchen Anspruch gerecht?

    Abstract
    After modeling expert user needs with regard to intellectual property information, we analyze and compare the main providers in this specific information area (Thomson DIALOG, Esp@cenet by the European Patent Office, Questel-Orbit, and STN International) in terms of system content and system functionality. The key question is whether the main providers are able to satisfy these expert user needs. For patent information, some special retrieval features such as chemical structure search (including Markush search), patent family references and citations search, biosequence search, and basic informetric functionality such as ranking, mapping, and visualization of information flows are realized. Considering the results of information science research, the practice of patent information shows unexhausted improvement opportunities (e.g., the application of bibliographic patent coupling and co-patent-citation for mapping patents, patent assignees, and technology specialties). For trademark search, users need multiple truncated search (realized) as well as phonetic search and image retrieval (not realized yet).

    Abstract
    According to Jean M. Tague-Sutcliffe "informetrics" is "the study of the quantitative aspects of information in any form, not just records or bibliographies, and in any social group, not just scientists" (Tague-Sutcliffe, 1992, 1). Leo Egghe also defines "informetrics" in a very broad sense. "(W)e will use the term' informetrics' as the broad term comprising all-metrics studies related to information science, including bibliometrics (bibliographies, libraries,...), scientometrics (science policy, citation analysis, research evaluation,...), webometrics (metrics of the web, the Internet or other social networks such as citation or collaboration networks), ..." (Egghe, 2005b,1311). According to Concepcion S. Wilson "informetrics" is "the quantitative study of collections of moderatesized units of potentially informative text, directed to the scientific understanding of information processes at the social level" (Wilson, 1999, 211). We should add to Wilson's units of text also digital collections of images, videos, spoken documents and music. Dietmar Wolfram divides "informetrics" into two aspects, "system-based characteristics that arise from the documentary content of IR systems and how they are indexed, and usage-based characteristics that arise how users interact with system content and the system interfaces that provide access to the content" (Wolfram, 2003, 6). We would like to follow Tague-Sutcliffe, Egghe, Wilson and Wolfram (and others, for example Björneborn & Ingwersen, 2004) and call this broad research of empirical information science "informetrics". Informetrics includes therefore all quantitative studies in information science. If a scientist performs scientific investigations empirically, e.g. on information users' behavior, on scientific impact of academic journals, on the development of the patent application activity of a company, on links of Web pages, on the temporal distribution of blog postings discussing a given topic, on availability, recall and precision of retrieval systems, on usability of Web sites, and so on, he or she contributes to informetrics. We see three subject areas in information science in which such quantitative research takes place, - information users and information usage, - evaluation of information systems, - information itself, Following Wolfram's article, we divide his system-based characteristics into the "information itself "-category and the "information system"-category. Figure 1 is a simplistic graph of subjects and research areas of informetrics as an empirical information science.

    Abstract
    There are at least three possible ways that documents are distributed by relevance: informetric (power law), inverse logistic, and dichotomous. The nature of the type of distribution has implications for the construction of relevance ranking algorithms for search engines, for automated (blind) relevance feedback, for user behavior when using Web search engines, for combining of outputs of search engines for metasearch, for topic detection and tracking, and for the methodology of evaluation of information retrieval systems.

Informationswissenschaft umfasst als Kerndisziplinen Information Retrieval, Wissensrepräsentation, Informetrie (einschließlich Web Science), Wissensmanagement und die Erforschung von Informations- bzw. Wissensgesellschaft und der Informationsmärkte (Stock & Stock, 2012). In vielen Forschungsprojekten befassen sich Informationswissenschaftler mit Themen, die auch von anderen Wissenschaftsdisziplinen bearbeitet werden. Informationswissenschaft ist also durchaus (auch) eine interdisziplinäre Angelegenheit. Dieses Themenheft von IWP stellt die Interdisziplinarität von Informationswissenschaft anhand von Beispielen der Forschungsergebnisse aus Düsseldorf in den Vordergrund.

    Abstract
    Norbert Henrichs war ein bedeutender Pionier der Informationswissenschaft in Deutschland. Wir widmen uns der von ihm aufgebauten Philosophiedokumentation und der damit eng verbundenen Textwortmethode sowie einer frühen Form der informetrischen Themenanalyse. Herausgestellt wird seine führende Rolle beim Bemühen um eine Institutionalisierung der Informationswissenschaft, die allerdings mit der nachhaltigen Etablierung der Gesellschaft für Information und Dokumentation (GID) nicht gelang. In seinem Spätwerk hinterfragte Henrichs den kapitalistischen Informationsmarkt und stellt das "Menschsein im Informationszeitalter" in den Fokus seiner Betrachtungen.

    Abstract
    Some documents provoke emotions in people viewing them. Will it be possible to describe emotions consistently and use this information in retrieval systems? We tested collective (statistically aggregated) emotion indexing using images as examples. Considering psychological results, basic emotions are anger, disgust, fear, happiness, and sadness. This study follows an approach developed by Lee and Neal (2007) for music emotion retrieval and applies scroll bars for tagging basic emotions and their intensities. A sample comprising 763 persons tagged emotions caused by images (retrieved from www.Flickr.com) applying scroll bars and (linguistic) tags. Using SPSS, we performed descriptive statistics and correlation analysis. For more than half of the images, the test persons have clear emotion favorites. There are prototypical images for given emotions. The document-specific consistency of tagging using a scroll bar is, for some images, very high. Most of the (most commonly used) linguistic tags are on the basic level (in the sense of Rosch's basic level theory). The distributions of the linguistic tags in our examples follow an inverse power-law. Hence, it seems possible to apply collective image emotion tagging to image information systems and to present a new search option for basic emotions. This article is one of the first steps in the research area of emotional information retrieval (EmIR).
