    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
    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
    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
    Einleitungsartikel zu einem Themenheft. 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
    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
    Gegenstand der empirischen Forschungsarbeit sind dargestellte wie empfundene Gefühle bei Videos. Sind Nutzer in der Lage, solche Gefühle derart konsistent zu erschließen, dass man deren Angaben für ein emotionales Videoretrieval gebrauchen kann? Wir arbeiten mit einem kontrollierten Vokabular für neun tionen (Liebe, Freude, Spaß, Überraschung, Sehnsucht, Trauer, Ärger, Ekel und Angst), einem Schieberegler zur Einstellung der jeweiligen Intensität des Gefühls und mit dem Ansatz der broad Folksonomy, lassen also unterschiedliche Nutzer die Videos taggen. Versuchspersonen bekamen insgesamt 20 Videos (bearbeitete Filme aus YouTube) vorgelegt, deren Emotionen sie indexieren sollten. Wir erhielten Angaben von 776 Probanden und entsprechend 279.360 Schiebereglereinstellungen. Die Konsistenz der Nutzervoten ist sehr hoch; die Tags führen zu stabilen Verteilungen der Emotionen für die einzelnen Videos. Die endgültige Form der Verteilungen wird schon bei relativ wenigen Nutzern (unter 100) erreicht. Es ist möglich, im Sinne der Power Tags die jeweils für ein Dokument zentralen Gefühle (soweit überhaupt vorhanden) zu separieren und für das emotionale Information Retrieval (EmIR) aufzubereiten.

    Wie kann man "Informationswissenschaft" abgrenzen? Was ist Informationswissenschaft? Wie kann man diese noch recht junge wissenschaftliche Disziplin definieren? Für die Beschreibung und Abgrenzung von Informationswissenschaft werden wir einige Anläufe machen und folgende Fragestellungen abarbeiten: Welches sind die wesentlichen Bestimmungsstücke und Aufgaben der Informationswissenschaft? Welche Rolle spielen Wissen und Information? Wie hat sich unsere Wissenschaft entwickelt? Haben die informationswissenschaftlichen Teildisziplinen unterschiedliche Geschichten? Mit welchen anderen Wissenschaftsdisziplinen ist die Informationswissenschaft eng verknüpft?

    Abstract
    Purpose - The object of this empirical research study is emotion, as depicted and aroused in videos. This paper seeks to answer the questions: Are users able to index such emotions consistently? Are the users' votes usable for emotional video retrieval? Design/methodology/approach - The authors worked with a controlled vocabulary for nine basic emotions (love, happiness, fun, surprise, desire, sadness, anger, disgust and fear), a slide control for adjusting the emotions' intensity, and the approach of broad folksonomies. Different users tagged the same videos. The test persons had the task of indexing the emotions of 20 videos (reprocessed clips from YouTube). The authors distinguished between emotions which were depicted in the video and those that were evoked in the user. Data were received from 776 participants and a total of 279,360 slide control values were analyzed. Findings - The consistency of the users' votes is very high; the tag distributions for the particular videos' emotions are stable. The final shape of the distributions will be reached by the tagging activities of only very few users (less than 100). By applying the approach of power tags it is possible to separate the pivotal emotions of every document - if indeed there is any feeling at all. Originality/value - This paper is one of the first steps in the new research area of emotional information retrieval (EmIR). To the authors' knowledge, it is the first research project into the collective indexing of emotions in videos.
