Abstract

Geisteswissenschaftliche Fachinformation erfordert eine enge Kooperation zwischen Literaturnachweis- und Terminologieinformationssystemen. Eine geeignete Dokumentationsmethode für die Auswertung geisteswissen- schaftlicher Literatur ist die Textwortwethode. Dem originalsprachig aufgenommenen Begriffsrepertoire ist ein einheitssprachiger Zugriff beizuordnen, der einerseits ein vollständiges und genaues Retrieval garantiert und andererseits den Aufbau fachspezifischer Wörterbücher vorantreibt

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

Dealing with information is one of the vital skills in the 21st century. It takes a fair degree of information savvy to create, represent and supply information as well as to search for and retrieve relevant knowledge. How does information (documents, pieces of knowledge) have to be organized in order to be retrievable? What role does metadata play? What are search engines on the Web, or in corporate intranets, and how do they work? How must one deal with natural language processing and tools of knowledge organization, such as thesauri, classification systems, and ontologies? How useful is social tagging? How valuable are intellectually created abstracts and automatically prepared extracts? Which empirical methods allow for user research and which for the evaluation of information systems? This Handbook is a basic work of information science, providing a comprehensive overview of the current state of information retrieval and knowledge representation. It addresses readers from all professions and scientific disciplines, but particularly scholars, practitioners and students of Information Science, Library Science, Computer Science, Information Management, and Knowledge Management. This Handbook is a suitable reference work for Public and Academic Libraries.

Rez. in: BuB 60(2008) H.10, S.756-758 (H. Wiesenmüller): "In erster Linie für am Thema Sacherschließung Interessierte ist dieses neue Lehrbuch, das der Düsseldorfer Informationswissenschaftler Wolfgang G. Stock gemeinsam mit Mechtild Stock verfasst hat. Als primäre Zielgruppe werden Studierende der »Informationswissenschaft, Informatik und Wirtschaftsinformatik, Wirtschaftswissenschaften, Informationswirtschaft, Information und Dokumentation, Bibliothekswesen, Computerlinguistik« (Seite XVI) genannt; daneben sind auch Praktiker aus diesen Bereichen angesprochen. In Abgrenzung zu anderen, stärker praktisch ausgerichteten Lehrbüchern wie etwa Jutta Bertrams »Einführung in die inhaltliche Erschließung«' haben die Autoren den Anspruch, einen »ausgewogenen Ausgleich [...] zwischen Theorie und Praxis« und »zwischen den beteiligten Wissenschaftsdisziplinen, vor allem Informationswissenschaft, Informatik und Bibliothekswissenschaft« (Seite XIII) zu bieten. Die Aufmachung des Bandes als eigenständige Monografie führt etwas in die Irre, denn faktisch handelt es sich um den zweiten Teil der »Einführung in die Informationswissenschaft«. Diese wird im Vorwort als Reihe bezeichnet, scheint aber von der Sache her eher ein mehrbändiges Werk zu sein. Tatsächlich wird im Text häufig auf den ersten Teil »Information Retrieval« verwiesen und empfohlen, beide Bände nebeneinander zu verwenden (Seite XVI). . . .
