Abstract

Indexing consists of both novel and more traditional techniques. Cutting-edge indexing techniques, such as automatic indexing, ontologies, and topic maps, were developed independently of older techniques such as thesauri, but it is now recognized that these older methods also hold expertise. Indexing describes various traditional and novel indexing techniques, giving information professionals and students of library and information sciences a broad and comprehensible introduction to indexing. This title consists of twelve chapters: an Introduction to subject readings and theasauri; Automatic indexing versus manual indexing; Techniques applied in automatic indexing of text material; Automatic indexing of images; The black art of indexing moving images; Automatic indexing of music; Taxonomies and ontologies; Metadata formats and indexing; Tagging; Topic maps; Indexing the web; and The Semantic Web.

Abstract

Ein Konferenzereignis der besonderen Art fand am 18. und 19. November 2010 in Luxemburg statt. Initiiert durch das Amt für Veröffentlichungen der Europäischen Union (http://publications.europa.eu) waren Bibliothekare und Information Professionals eingeladen, um über die Zukunft mehrsprachiger kontrollierter Vokabulare in Informationssystemen und insbesondere deren Beitrag zum Semantic Web zu diskutieren. Organisiert wurde die Konferenz durch das EuroVoc-Team, das den Thesaurus der Europäischen Union bearbeitet. Die letzte EuroVoc-Konferenz fand im Jahr 2006 statt. In der Zwischenzeit ist EuroVoc zu einem ontologie-basierten Thesaurusmanagementsystem übergegangen und hat systematisch begonnen, Semantic-Web-Technologien für die Bearbeitung und Repräsentation einzusetzen und sich mit anderen Vokabularen zu vernetzen. Ein produktiver Austausch fand mit den Produzenten anderer europäischer und internationaler Vokabulare (z.B. United Nations oder FAO) sowie Vertretern aus Projekten, die an Themen über automatische Indexierung (hier insbesondere parlamentarische und rechtliche Dokumente) sowie Interoperabilitiät zwischen Vokabularen arbeiten, statt.

Abstract

Thesauri can be useful resources for indexing and retrieval on the Semantic Web, but often they are not published in RDF/OWL. To convert thesauri to RDF for use in Semantic Web applications and to ensure the quality and utility of the conversion a structured method is required. Moreover, if different thesauri are to be interoperable without complicated mappings, a standard schema for thesauri is required. This paper presents a method for conversion of thesauri to the SKOS RDF/OWL schema, which is a proposal for such a standard under development by W3Cs Semantic Web Best Practices Working Group. We apply the method to three thesauri: IPSV, GTAA and MeSH. With these case studies we evaluate our method and the applicability of SKOS for representing thesauri.

The objective of this research was to investigate the extent to which thesauri have the potential to support the search behaviour of nanoscience and technology researchers while interacting with an electronic book digital library. Transaction log data was obtained from a nanoscience and technology digital library to investigate the nature, type and characteristics of users' queries and search terms. The specific objectives was to assess the extent to which users' search terms matched with those found in two well-established thesauri attached o the INSPEC and Compendex databases.

Abstract

This thesis focuses on conversion of vocabularies for representation and integration of collections on the Semantic Web. A secondary focus is how to represent metadata schemas (RDF Schemas representing metadata element sets) such that they interoperate with vocabularies. The primary domain in which we operate is that of cultural heritage collections. The background worldview in which a solution is sought is that of the Semantic Web research paradigmwith its associated theories, methods, tools and use cases. In other words, we assume the SemanticWeb is in principle able to provide the context to realize interoperable collections. Interoperability is dependent on the interplay between representations and the applications that use them. We mean applications in the widest sense, such as "search" and "annotation". These applications or tasks are often present in software applications, such as the E-Culture application. It is therefore necessary that applications requirements on the vocabulary representation are met. This leads us to formulate the following problem statement: HOW CAN EXISTING VOCABULARIES BE MADE AVAILABLE TO SEMANTIC WEB APPLICATIONS?
We refine the problem statement into three research questions. The first two focus on the problem of conversion of a vocabulary to a Semantic Web representation from its original format. Conversion of a vocabulary to a representation in a Semantic Web language is necessary to make the vocabulary available to SemanticWeb applications. In the last question we focus on integration of collection metadata schemas in a way that allows for vocabulary representations as produced by our methods.

Abstract

Thesauri are Knowledge Organization Systems (KOS), that arise from the consensus of wide communities. They have been in use for many years and are regularly updated. Whereas in the past thesauri were designed for information professionals for indexing and searching, today there is a demand for conceptual vocabularies that enable inferencing by machines. The development of the Semantic Web has brought a new opportunity for thesauri, but thesauri also face the challenge of proving that they add value to it. The evolution of thesauri toward their integration with the Semantic Web is examined. Elements and structures in the thesaurus standard, ISO 25964, and SKOS (Simple Knowledge Organization System), the Semantic Web standard for representing KOS, are reviewed and compared. Moreover, the integrity rules of thesauri are contrasted with the axioms of SKOS. How SKOS has been applied to represent some real thesauri is taken into account. Three thesauri are chosen for this aim: AGROVOC, EuroVoc and the UNESCO Thesaurus. Based on the results of this comparison and analysis, the benefits that Semantic Web technologies offer to thesauri, how thesauri can contribute to the Semantic Web, and the challenges that would help to improve their integration with the Semantic Web are discussed.

Abstract

The World Wide Web and the use of HTML-based information displays has greatly increased access to online information sources, but at the same time limits the ways in which they can be used. By the same token, Web-based indexing and search engines give us access to the full text of online documents, but make it difficult to access them in any kind of organized, systematic way. For years before the advent of the Internet, lexicographers built weIl-structured subject thesauri to organize large collections of documents. These have since been converted into electronic form and even put online, but in ways that are largely uncoordinated and not useful for searching. This paper describes some of the ways in which XML-based Web services could be used to coordinate subject thesauri and other online vocabulary sources to create a "Thesauro-Web" that could be used by both searchers and indexers to improve subject access an the Internet.

Abstract

Zahlreich sind die Versuche, Strukturen begrifflicher Relationen, wie sie in Thesauren niedergelegt sind, durch Visualisierung verständlicher zu machen, doch nirgends ist das bisher in überzeugender Weise gelungen. Damit blieb der Gebrauch von Thesauri durchweg auf Fachleute (Dokumentare) verwiesen und eine Anwendung in der Breite fand nicht statt. Mit den neuen Möglichkeiten visueller und auditiver Darstellung, wie sie nun die Informationstechnologie bietet, läßt sich das ändern. Berichtet wird über ein Projekt im Zusammenhang mit der EXP02000, bei dem versucht wird, bisher weitgehend ungenutzte Potentiale von Thesauri für die Interaktion am Computer zu nutzen. Akteur am Point of Information ist dabei jeder Interessierte, gleich ob Laie oder Fachmann, Gegenstand der Strukturierung die Welt im Jahre 2000, Zugangssprache die Sprache der allgemeinen Kommunikation. Einsicht in die begrifflichen Strukturen in dem Sinne, daß man sie versteht, ist nicht erforderlich, die multimediale Präsentation ermöglicht sensitives Erfassen und nähert sich gewohntem intuitiven Umgang mit Begrifflichkeiten. Jedermann kann so durch den Gedankenraum "reisen", sinnvollen Verknüpfungen und Wirkketten nachspüren, begriffliche Klärung und Einsichten gewinnen, für den Begriff das richtige Wort finden. Bei solch einer Reise wird er zugleich auch auf überraschende Zusammenhänge stoßen. Der Sprung in die Quellen wird von jedem angesteuerten Punkt aus möglich. Die Grenzen des herkömmlichen Information Retrieval zerfließen damit und öffnen sich hin zu neuen, bisher vernachlässigten Räumen: dem Erleben, der Anregung, dem sinnvollen Spiel, der Überraschung, dem unterhaltsamen Lernen

Abstract

This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

Abstract

This document describes in brief how to express the content and structure of a thesaurus, and metadata about a thesaurus, in RDF. Using RDF allows data to be linked to and/or merged with other RDF data by semantic web applications. The Semantic Web, which is based on the Resource Description Framework (RDF), provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.

Rez. in: Information: Wissenschaft & Praxis 56(2005) H.5/6, S.337 (W. Ratzek): "Bettina Brühl legt mit "Thesauri und Klassifikationen" ein Fleißarbeit vor. Das Buch mit seiner Auswahl von über 150 Klassifikationen und Thesauri aus Naturwissenschaft, Technik, Wirtschaft und Patenwesen macht es zu einem brauchbaren Nachschlagewerk, zumal auch ein umfassender Index nach Sachgebieten, nach Datenbanken und nach Klassifikationen und Thesauri angeboten wird. Nach einer 13-seitigen Einführung (Kapitel 1 und 2) folgt mit dem 3. Kapitel die "Darstellung von Klassifikationen und Thesauri", im wesentlichen aus den Beschreibungen der Hersteller zusammengestellt. Hier werden Dokumentationssprachen der Fachgebiete - Naturwissenschaften (3.1) und deren Spezialisierungen wie zum Beispiel "Biowissenschaften und Biotechnologie", "Chemie" oder "Umwelt und Ökonomie", aber auch "Mathematik und Informatik" (?) auf 189 Seiten vorgestellt, - Technik mit zum Beispiel "Fachordnung Technik", "Subject Categories (INIS/ ETDE) mit 17 Seiten verhältnismäßig knapp abgehandelt, - Wirtschaft mit "Branchen-Codes", "Product-Codes", "Länder-Codes"",Fachklas-sifikationen" und "Thesauri" ausführlich auf 57 Seiten präsentiert, - Patente und Normen mit zum Beispiel "Europäische Patentklassifikation" oder "International Patent Classification" auf 33 Seiten umrissen. Jedes Teilgebiet wird mit einer kurzen Beschreibung eingeleitet. Danach folgen die jeweiligen Beschreibungen mit den Merkmalen: "Anschrift des Erstellers", "Themen-gebiet(e)", "Sprache", "Verfügbarkeit", "An-wendung" und "Ouelle(n)". "Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen" heißt es in der Verlagsinformation. Zwar ist es nicht notwendig, die informationswissenschaftlichen Aspekte der Klassifikationen und Thesauri abzuhandeln, aber ein Hinweis auf die Bedeutung der Information und Dokumentation und/oder der Informationswissenschaft wäre schon angebracht, um in der Welt der Informations- und Wissenswirtschaft zu demonstrieren, welchen Beitrag unsere Profession leistet. Andernfalls bleibt das Blickfeld eingeschränkt und der Anschluss an neuere Entwicklungen ausgeblendet. Dieser Anknüpfungspunkt wäre beispielsweise durch einen Exkurs über Topic Map/Semantic Web gegeben. Der Verlag liefert mit der Herausgabe die ses Kompendiums einen nützlichen ersten Baustein zu einem umfassenden Verzeichnis von Thesauri und Klassifikationen."

Abstract

The task of an information architect is to create web sites where users can actually find the information they are looking for. As the ocean of information rises and leaves what we seek ever more deeply buried in what we don't seek, this discipline becomes ever more relevant. Information architecture involves many different aspects of web site creation and organization, but its principal tools are information organization techniques developed in other disciplines. Most of these techniques come from library science, such as thesauri, taxonomies, and faceted classification. Topic maps are a relative newcomer to this area and bring with them the promise of better-organized web sites, compared to what is possible with existing techniques. However, it is not generally understood how topic maps relate to the traditional techniques, and what advantages and disadvantages they have, compared to these techniques. The aim of this paper is to help build a better understanding of these issues.

Abstract

Thesauri have been important information and knowledge organisation tools for more than three decades. The recent emergence and phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have yet been carried out to evaluate how end-users, for whom all these efforts are ostensibly made, interact with and make use of thesauri for query building and expansion. The present paper reports a pilot study carried out to determine the extent to which a thesaurus-enhanced search interface to a web-based database aided end-users in their selection of search terms. The study also investigated the ways in which users interacted with the thesaurus structure, terms, and interface. Thesaurusbased searching and browsing behaviours adopted by users while interacting with the thesaurus-enhanced search interface were also examined. 1. Introduction The last decade has witnessed the emergence of a broad range of applications for knowledge structures in general and thesauri in particular. A number of researchers have predicted that thesauri will increasingly be used in retrieval rather than for indexing (Milstead, 1998; Aitchison et al., 1997) and that their application in information retrieval systems will become more diverse due to the growth of fulltext databases accessed over the Internet (Williamson, 2000). Some researchers have emphasised the need for tailoring the structure and content of thesauri as tools for end-user searching (Bates, 1986; Strong and Drott, 1986; Anderson and Rowley, 1991; Lopez-Huertas, 1997) while others have suggested thesaurus-enhanced user interfaces to support query formulation and expansion (Pollitt et.al., 1994; Jones et.al., 1995; Beaulieu, 1997). The recent phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have been carried out to evaluate the ways in which end-users interact with and make use of online thesauri for query building and expansion. The work reported here expands an a pilot study (Shiri and Revie, 2001) carried out to investigate user - thesaurus interaction in the domains of biology and veterinary medicine.
