- Abstract
- Es wird versucht, quantitative Werte zur Messung der Informationskompetenz von Volkswirtschaften zu entwickeln. Zudem sollen Korrelationen zwischen der Informationskompetenz und der wirtschaftlichen Leistungsfähigkeit darüber Auskunft geben, wie Gesamtwirtschaft und Inforinationswirtschaft eines Landes zusammenhängen. Operationalisierung. "Informationskompetenz" wird durch den Umsatz auf nationalen Business-toBusiness-Märkten operationalisiert. Abgeleitete Größen sind Pro-KopfImport- und Exportvolumen, Informationsproduktion und -konsumtion (insgesamt und pro Kopf) sowie der Anteil der Informationswirtschaft am jeweiligen nationalen Bruttoinlandsprodukt (BIP). Datenbasis. Im Rahmen der "Member States' Study" der Europäischen Kommission wurden für den gesamten Europäischen Wirtschaftsraum (EWR; Staaten der Europäischen Union sowie Norwegen und Island) für die Jahre 1994 und 1997 Umsatzzahlen der 17 Länder erhoben. Diese Zahlen wurden auf Plausibilität überprüft und unserer Fragestellung zugrundegelegt. Ergebnisse. Der Anteil der Informationswirtschaft am BIP ist derart gering (EWR: 0,070% im Jahr 1997), daß er nahezu ignoriert werden kann. Die Korrelation zwischen dem BIP pro Kopf und der Informationskonsumtion pro Kopf ist jedoch äußerst hoch (+0,715 im Jahr 1994 und +0,642 im Jahr 1997), ebenso die Korrelation zwischen BIP pro Kopf und Informationsimport pro Kopf (+0,588 im Jahr 1994 sowie +0,583 im Jahr 1997)

- Als Maß für die Produktivität und den Einfluß von Forschern, wissenschaftlichen Einrichtungen und Fachbereichen dienen häufig anhand von Publikations- und Zitationsanalysen erstellte Ranglisten. Doch nach welchen Kriterien sind die in elektronischen Fachdatenbanken gespeicherten Informationen auszuwerten, um ein einigermaßen zutreffendes Abbild der Forschungsleistung zu erhalten?

- Abstract
- Mit dem Aufkommen der Wissensgesellschaft wird Information zum Wirtschaftsgut. Digitale Wirtschaftsgüter - Content wie Software - werden entweder selbst vermarktet (z.B. bei kommerziellen Informationsdiensten) oder dienen als Lockangebote für Werbung (z.B. bei Suchmaschinen mit "sponsored links"). Aufgrund der Besonderheiten des vertriebenen Produkts unterscheiden sich die Wettbewerbsstrategien von Informationsanbietern von denen nicht-digitaler Güter. Zu beachten ist zudem der "illegale" Informationsmarkt (Schwarzkopien). Im Zentrum des Buches steht zwar eine ökonomische Analyse des Informationsmarktes, behandelt werden aber auch Informationssoziologie und -politologie, Informationsrecht sowie Informationsethik.

- Abstract
- Betrachtet wird der europäische Entwurf der Informationsgesellschaft in der Folge des EG-Weißbuches von 1993 und der Tagung in Korfu (1994). Es zeigt sich die zentrale Rolle des Informationsengineering. Hier geht es um die Produktion, Speicherung, Verteilung und Abfrage von Informationen. Wirtschaftliche Kennziffern beleuchten den deutschen Informationsmarkt (Online-Datenbanken, CD-ROM, Videotex, professionelle Informationsvermittlung). Die Relevanz elektronischer Informationsdienste für die betriebswirtschaftliche Praxis (Branchen- und Konkurrenzanalysen, Benchmarking) wird anhand von konkreten Beispielrecherchen demonstriert. Elektronische Datenbanken gestatten, die wissenschaftliche Forschung im Rahmen der Wissenschaftsevaluation mittels Publikations- Zitations- oder Themenanalysen zu beschreiben und zu bewerten. Ein Kapitel beschreibt detailliert diejenigen Tätigkeiten, die beim Auf- und Ausbau elektronischer Informationsdienste routinemäßig durchgeführt werden, mit dem Ziel, Qualitätsmerkmale für die Informationstätigkeit abzuleiten. Die Komplexität der Informationstätigkeiten führt u.a. in Bereiche der fuzzy logic und der Informationshermeneutik. Abgeschlossen wird das Buch mit einer 'Anatomie' einer konkreten Datenbank. Beispiel ist die ifo Literaturdatenbank, die erfolgreich bei mehreren Hosts als Online-Datenbank sowie zusätzlich als CD-ROM Datenbank vermarktet wird

- Abstract
- Suchmaschinen im World Wide Web arbeiten automatisch: Sie spüren Dokumente auf, indexieren sie, halten die Datenbank (mehr oder minder) aktuell und bieten den Kunden Retrievaloberflächen an. In unserem Known-Item-Retrievaltest (Password 11/2000) schnitten - in dieser Reihenfolge - Google, Alta Vista, Northern Light und FAST (All the Web) am besten ab. Die letzten drei Systeme arbeiten mit einer Kombination aus informationslinguistischen und informationsstatistischen Algorithmen, weshalb wir sie hier gemeinsam besprechen wollen. Im Zentrum unserer informationswissenschaftlichen Analysen stehen die "Highlights" der jeweiligen Suchwerkzeuge

- Abstract
- In Password 11/2000 wurden durch einen Retrievaltest die qualitativ führenden Suchwerkzeuge im Internet bestimmt. In den nächsten Teilen unseres State of the Art - Berichts über Retrievalsysteme im World Wide Weh beschreiben wir einzelne interessante Ansätze der Technik der TopSuchwerkzeuge. Den Anfang machen die klassifikatorischen Verzeichnisse Yahoo! und das Open Directory-Projekt sowie das System Oingo, das im Rahmen eines "semantischen Retrievals" das Homonym- und Synonymproblem angeht

- Abstract
- Dimensionen der Zeitschriftenszientometrie sind (1.) die Produktion der Zeitschrift (Artikel, Autoren), (2.) der Inhalt (Themen) (3.) die Rezeption (Leser), (4.) die formale Fachkommunikation (Referenzen, Zitationen) sowie (5.) die Redaktion (Redaktionspolitik, Verlag). Die Zeitschrift "BuB - Forum für Bibliothek und Information" (BuB) wird einer szientometrischen Analyse unterzogen. BuB ist die auflagenstärkste deutschsprachige Zeitschrift des Bibliotheks- und Informationswesens. Innerhalb des Beobachtungszeitraums von 1990 bis 2003 sind 4.297 Beiträge mit insgesamt 6.803 Referenzen intellektuell ausgewertet worden. Im Vergleich zu erwarteten informetrischen Regelmäßigkeiten zeigt BuB bemerkenswerte Besonderheiten: Nicht ein Top-Autor, sondern eine über Jahre hinweg recht homogene Gruppe von Verfassern dominiert die Literaturproduktion bei BuB. Bei den Referenzen zeigt sich eine sehr hohe Konzentration auf die eigene Zeitschrift. BuB gleicht einer Insel, an die nur wenige fremde Informationen angespült werden. Obwohl Männer und Frauen jeweils 50 Prozent der Beiträge erarbeiten, so gibt es doch sowohl Männerdomänen (vor allem Rezensionen, aber auch Aufsätze) als auch Frauendomänen (Kurzbeiträge und Tagungsberichte). Die Halbwertszeit der Referenzen ist mit 2,7 Jahre sehr niedrig, Halbwertszeiten zitierter Monographien sind dabei höher als die der zitierten Zeitschriftenartikel.

- Abstract
- Web Search Engines und Web Directories sind die technologische Speerspitze im High-Tech-Bereich Internet. Als Suchassistenten gestatten sie Laien und Profi-Searchern gleichsam einen optimalen Einstieg in die Vielfalt der Informationsquellen des World Wide Web, Sie ermöglichen durch eine Kombination aus hierarchisch geordnetem kontrollierten Vokabular, automatischer Indexierung sowie diverser Synonym-, Homonym- und Fachwörterbücher einen zielgenauen Zugriff auf WebSites. - Stop! Glauben Sie das? Wir waren skeptisch und haben Suchmaschinen und Suchverzeichnisse genau angeschaut. Durchgeführt wurde ein Retrievaltest, der unterschiedliche Suchsysteme mit jeweils dergleichen Anfrage konfrontierte, auf die wir bereits die Antwort wussten ("Known Item Search"). Skizziert werden zudem bisher ausgearbeitete empirische Erhebungen zur Evaluation von Web-Retrievalsystemen, angefangen von seriösen informationswissenschaftlichen Forschungen bis hinzu den Tests in Publikumszeitschriften

- Abstract
- Am 26. November 1987 hielt Wolf Rauch seine akademische Antrittsrede an der Karl-Franzens-Universität Graz (Rauch 1988). Sein Thema: Was ist Informationswissenschaft? Mit Rauchs Professur beginnt in Österreich die institutionalisierte Informationswissenschaft, war Rauchs Institut doch das erste seiner Art in diesem Land (Rauch/Schlögl 2009). Seit diesem Ereignis sind 25 Jahre vergangen. Wo steht Informationswissenschaft heute?
- Content
- 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
- Die populären Web 2.0-Dienste werden von Prosumern - Produzenten und gleichsam Konsumenten - nicht nur dazu genutzt, Inhalte zu produzieren, sondern auch, um sie inhaltlich zu erschließen. Folksonomies erlauben es dem Nutzer, Dokumente mit eigenen Schlagworten, sog. Tags, zu beschreiben, ohne dabei auf gewisse Regeln oder Vorgaben achten zu müssen. Neben einigen Vorteilen zeigen Folksonomies aber auch zahlreiche Schwächen (u. a. einen Mangel an Präzision). Um diesen Nachteilen größtenteils entgegenzuwirken, schlagen wir eine Interpretation der Tags als natürlichsprachige Wörter vor. Dadurch ist es uns möglich, Methoden des Natural Language Processing (NLP) auf die Tags anzuwenden und so linguistische Probleme der Tags zu beseitigen. Darüber hinaus diskutieren wir Ansätze und weitere Vorschläge (Tagverteilungen, Kollaboration und akteurspezifische Aspekte) hinsichtlich eines Relevance Rankings von getaggten Dokumenten. Neben Vorschlägen auf ähnliche Dokumente ("more like this!") erlauben Folksonomies auch Hinweise auf verwandte Nutzer und damit auf Communities ("more like me!").

- 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.

- Abstract
- In einer szientometrischen bzw. informetrischen Studie werden internationale wie deutschsprachige Zeitschriften der Informations-/Bibliothekswissenschaft und -praxis mittels Zitationsanalyse und Expertenbefragung analysiert. Die zitatenanalytischen Kennwerte umfassen den Impact Factor, die Halbwertszeit, die Zitierfreudigkeit, die relative Häufigkeit von Zeitschriftenselbstreferenzen sowie Soziogramme der einflussreichen Periodika. Der Fragebogen erhebt die Lesehäufigkeit, die Einsetzbarkeit der gelesenen Journale im Tätigkeitsbereich, die Publikationstätigkeit und die Publikationspräferenz sowohl für alle Respondenten als auch für abgrenzbare Gruppen (Praktiker vs. Wissenschaftler, Bibliothekare vs. Dokumentare vs. Informationswissenschaftler, öffentlicher Dienst vs. Informationswirtschaft vs. andere Wirtschaftsunternehmen).
