Abstract

A thesaurus is a controlled vocabulary designed to allow for effective information retrieval. It con- sists of different kinds of semantic relationships, with the aim of guiding users to the choice of the most suitable index and search terms for expressing a certain concept. The relational semantics of a thesaurus deal with methods to connect terms with related meanings and arc intended to enhance information recall capabilities. In this paper, focused on hierarchical relations, different aspects of the relational semantics of thesauri, and among them the possibility of developing richer structures, are analyzed. Thesauri are viewed as semantic tools providing, for operational purposes, the representation of the meaning of the terms. The paper stresses how theories of semantics, holding different perspectives about the nature of meaning and how it is represented, affect the design of the relational semantics of thesauri. The need for tools capable of representing the complexity of knowledge and of the semantics of terms as it occurs in the literature of their respective subject fields is advocated. It is underlined how this would contribute to improving the retrieval of information. To achieve this goal, even though in a preliminary manner, we explore the possibility of setting against the framework of thesaurus design the notions of language games and hermeneutic horizon.

Abstract

This article describes the process of constructing a thesaurus based on original historical documents located in the Archivo del Reino de Valencia, one of the most important historical archives in Spain. After examining precedents, we discuss the methodology used and its application. The aim of the project was to provide visibility to information contained in these historical documents which would otherwise have remained inaccessible and to do so in the clearest, most rigorous, and most useful way possible for both the specialized user and the general public. The use of information technology as a management tool is not as common in archives, especially historical archives, as in other documentation areas such as libraries. A pilot project was therefore set up to create an intranet support for managing four specific historical archives containing documents dating from the 13th to the 20th centuries. The most important part of this project was that of exploring the viability of constructing a thesaurus to become part of the automated program for archive description and checking.

Abstract

A multilingual thesaurus' development needs the appropriate methodological considerations not only for linguistics, but also cultural heterogeneity, as demonstrated in this report on the multilingual project of the Art & Architecture Thesaurus (AAT) in the Chinese language, which has been a collaboration between the Academia Sinica Center for Digital Culture and the Getty Research Institute for more than a decade. After a brief overview of the project, the paper will introduce a holistic methodology for considering how to enable Western art to be accessible to Chinese users and Chinese art accessible to Western users. The conceptual and structural issues will be discussed, especially the challenges of developing terminology in two different cultures. For instance, some terms shared by Western and Chinese cultures could be understood differently in each culture, which raises questions regarding their locations within the hierarchical structure of the AAT. Finally, the report will provide cases to demonstrate how the Chinese-Language AAT language supports online exhibitions, digital humanities and linking of digital art history content to the web of data.

Abstract

Die Arbeit analysiert die dynamische Entwicklung und den Gebrauch von Thesaurusbegriffen. Zusätzlich konzentriert sie sich auf die Faktoren, die die Zahl von Indexbegriffen pro Dokument oder Zeitschrift beeinflussen. Als Untersuchungsobjekt dienten der MeSH und die entsprechende Datenbank "MEDLINE". Die wichtigsten Konsequenzen sind: 1. Der MeSH-Thesaurus hat sich durch drei unterschiedliche Phasen jeweils logarithmisch entwickelt. Solch einen Thesaurus sollte folgenden Gleichung folgen: "T = 3.076,6 Ln (d) - 22.695 + 0,0039d" (T = Begriffe, Ln = natürlicher Logarithmus und d = Dokumente). Um solch einen Thesaurus zu konstruieren, muss man demnach etwa 1.600 Dokumente von unterschiedlichen Themen des Bereiches des Thesaurus haben. Die dynamische Entwicklung von Thesauri wie MeSH erfordert die Einführung eines neuen Begriffs pro Indexierung von 256 neuen Dokumenten. 2. Die Verteilung der Thesaurusbegriffe erbrachte drei Kategorien: starke, normale und selten verwendete Headings. Die letzte Gruppe ist in einer Testphase, während in der ersten und zweiten Kategorie die neu hinzukommenden Deskriptoren zu einem Thesauruswachstum führen. 3. Es gibt ein logarithmisches Verhältnis zwischen der Zahl von Index-Begriffen pro Aufsatz und dessen Seitenzahl für die Artikeln zwischen einer und einundzwanzig Seiten. 4. Zeitschriftenaufsätze, die in MEDLINE mit Abstracts erscheinen erhalten fast zwei Deskriptoren mehr. 5. Die Findablity der nicht-englisch sprachigen Dokumente in MEDLINE ist geringer als die englische Dokumente. 6. Aufsätze der Zeitschriften mit einem Impact Factor 0 bis fünfzehn erhalten nicht mehr Indexbegriffe als die der anderen von MEDINE erfassten Zeitschriften. 7. In einem Indexierungssystem haben unterschiedliche Zeitschriften mehr oder weniger Gewicht in ihrem Findability. Die Verteilung der Indexbegriffe pro Seite hat gezeigt, dass es bei MEDLINE drei Kategorien der Publikationen gibt. Außerdem gibt es wenige stark bevorzugten Zeitschriften."

Abstract

Anfang März 2013 veröffentlicht, behandelt ISO 25964-2 die Interoperabilität zwischen Thesauri und anderen Vokabularien. Es geht dabei hauptsächlich um die theoretischen Grundlagen und die praktische Durchführung von Thesaurusföderationen. Zu den behandelten Vokabulartypen zählen Klassifikationen, Aktenpläne für die Schriftgutverwaltung, Taxonomien, Schlagwortlisten, Normdateien für Individualnamen, Ontologien, Terminologiedatenbanken und Synonymringe.

"Interoperabilität bedeutet, dass zwei oder mehrere Systeme oder Systemkomponenten Informationen austauschen und nutzen können. Diese Fähigkeit ist von grundsätzlicher Bedeutung für Informationsnetzwerke, auf die wir alle angewiesen sind, und mehr noch für die Entwicklung des Semantischen Web. Bei Thesauri gibt es zwei Ebenen der Interoperabilität: 1. Erstellung des Thesaurus in einer standardisierten Form, um den Import und die Nutzung des Thesaurus in anderen Systemen zu gewährleisten (dies wurde in ISO 25964-1 behandelt und 2011 publiziert). 2. Ergänzende Nutzung von weiteren Vokabularien und zwar durch die Erstellung von Mappings zwischen den Begriffen eines Thesaurus und denen eines anderen Vokabulars (Thema von ISO 25964-2). Nur wenn Mappings mit der empfohlenen Sorgfalt von ISO 25964-2 durchgeführt werden, kann sichergestellt werden, dass die auf ihnen basierenden Verknüpfungen im Semantic Web den nichtsahnenden Netzsurfer nicht zu irreführenden Ergebnissen führen.
Der vollständige Titel von Teil 2 lautet "Information and documentation - Thesauri and interoperability with other vocabularies - Teil 2: Interoperability with other vocabularies". Wichtige Themen, die der Standard behandelt, sind Strukturmodelle für das Mapping, Richtlinien für Mappingtypen und der Umgang mit Präkombination, die besonders bei Klassifikationen, Taxonomien und Schlagwortsystemen vorkommt. Das primäre Augenmerk von ISO 25964 gilt den Thesauri, und mit Ausnahme von Terminologien existieren keine vergleichbaren Standards für die anderen Vokabulartypen. Statt zu versuchen, diese normativ darzustellen, behandelt Teil 2 ausschließlich die Interoperabilität zwischen ihnen und den Thesauri. Die Kapitel für die einzelnen Vokabulartypen decken jeweils folgende Sachverhalte ab: - Schlüsseleigenschaften des Vokabulars (deskriptiv, nicht normativ) - Semantische Komponenten/Beziehungen (deskriptiv, nicht normativ) Sofern anwendbar, Empfehlungen für das Mapping zwischen Vokabular und Thesaurus (normativ).
Im Fall von Ontologien, Terminologien und Synonymringen ist das Mapping in oder aus einem Thesaurus nicht immer nützlich. Hier sind andere Formen sich gegenseitig befruchtender Nutzung zu empfehlen. Dies gilt besonders für Ontologien, die im Kontext des Semantischen Web kombiniert mit Thesauri eingesetzt werden können. ISO 25964-2 zeigt die Unterschiede zwischen Thesauri und Ontologien auf und gibt Beispiele für die Möglichkeiten interoperabler Funktionen. Praktische Implementation und weiterführende Arbeiten Und was bedeutet dies für SKOS, dem W3C-Standard für die Veröffentlichung von Simple Knowledge Organization Systems im Web? Die Arbeitsgruppen von SKOS und ISO 25964 haben glücklicherweise eng zusammengearbeitet, was sich in einer guten Kompatibilität der beiden Standards äußert. Gemeinsam haben sie eine Tabelle erarbeitet, die die Übereinstimmungen zwischen den Datenmodellen von ISO 25964 und SKOS/SKOS-XL aufzeigt und nun beim ISO 25964-Sekretariat unter http://www.niso.org/schemas/iso25964/frei zugänglich ist. Die Tabelle ist formal kein Bestandteil der beiden Standards, aber von beiden abhängig. Das macht sie zu einem Beispiel für die Entwicklung praktischer Tools für das sich erweiternde Semantische Web durch die Gemeinschaft seiner Nutzer."

Abstract

The use of Knowledge Organization Systems (KOSs) in aggregated metadata collections facilitates the implementation of search mechanisms operating on the same term or keyphrase space, thus preparing the ground for improved browsing, more accurate retrieval and better user profiling. Automatic thesaurus-based keyphrase extraction appears to be an inexpensive tool to obtain this information, but the studies on its effectiveness are scattered and do not consider the practical applicability of these techniques compared to the quality obtained by involving human experts. This paper presents an evaluation of keyphrase extraction using the KEA software and the AGROVOC vocabulary on a sample of a large collection of metadata in the field of agriculture from the AGRIS database. This effort includes a double evaluation, the classical automatic evaluation based on precision and recall measures, plus a blind evaluation aimed to contrast the quality of the keyphrases extracted against expert-provided samples and against the keyphrases originally recorded in the metadata. Results show not only that KEA outperforms humans in matching the original keyphrases, but also that the quality of the keyphrases extracted was similar to those provided by humans.

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 purpose of this article is to identify the most important factors and features in the evolution of thesauri and ontologies through a dialectic model. This model relies on a dialectic process or idea which could be discovered via a dialectic method. This method has focused on identifying the logical relationship between a beginning proposition, or an idea called a thesis, a negation of that idea called the antithesis, and the result of the conflict between the two ideas, called a synthesis. During the creation of knowl­edge organization systems (KOSs), the identification of logical relations between different ideas has been made possible through the consideration and use of the most influential methods and tools such as dictionaries, Roget's Thesaurus, thesaurus, micro-, macro- and metathesauri, ontology, lower, middle and upper level ontologies. The analysis process has adapted a historical methodology, more specifically a dialectic method and documentary method as the reasoning process. This supports our arguments and synthesizes a method for the analysis of research results. Confirmed by the research results, the principle of unity has shown to be the most important factor in the development and evolution of the structure of knowl­edge organization systems and their types. There are various types of unity when considering the analysis of logical relations. These include the principle of unity of alphabetical order, unity of science, semantic unity, structural unity and conceptual unity. The results have clearly demonstrated a movement from plurality to unity in the assembling of the complex structure of knowl­edge organization systems to increase information and knowl­edge storage and retrieval performance.

Abstract

Die hier vorgeschlagene Art der Visualisierung, die vor allem die Multiaspektivität und die dynamische Struktur von Wissen aufdeckt und transparent gestaltet, wird an drei Beispielen erläutert, die z.T. ungelöste Probleme der Wissensverarbeitung darstellen: die klassifikatorische Kompatibilität von Aussagen aus unterschiedlichen Wissensgebieten die Darstellung und Auswertung von Wissensänderungen, die Selektion Wissen mit dem Ziel einer Problemlösung. Am Beispiel der Lösung einer Erfindungsaufgabe wird die Funktion von Facetten als Ordnungsmittel für die Strukturbilder ausfiihrlich demonstriert

Abstract

Die Komplexizität medizinischer Fragestellungen und des medizinischen Informationsmanagements war seit den Anfängen der Informatik immer ein besonders wichtiges Thema. Trotz des Scheiterns der Künstlichen Intelligenz in den 80er Jahren des vorigen Jahrhunderts haben deren Kernideen Früchte getragen. Durch kongruente Entwicklung einer Reihe anderer Wissenschaftsdisziplinen und der exponentiellen Entwicklung im Bereich Computerhardware konnten die gestellten, hohen Anforderungen bei der medizinischen Informationssuche doch noch erfüllt werden. Die programmatische Forderung von Tim Berners-Lee betreffend "Semantic Web" im Jahr 2000 hat dem Thema Ontologien für maschinenlesbare Repositorien in Allgemein- und Fachsprache breitere Aufmerksamkeit gewonnen. Da in der Medizin (PubMed) mit dem von NLM schon vor 20 Jahren entwickelten Unified Medical Language System (UMLS) eine funktionierende Ontologie in Form eines semantischen Netzes in Betrieb ist, ist es auch für Medizinbibliothekare und Medizindokumentare hoch an der Zeit, sich damit zu beschäftigen. Ontologien können im Wesen, trotz der informatisch vernebelnden Terminologie, als Werkzeuge der Klassifikation verstanden werden. Hier sind von seiten der Bibliotheks- und Dokumentationswissenschaft wesentliche Beiträge möglich. Der vorliegende Bericht bietet einen Einstieg in das Thema, erklärt wesentliche Elemente des UMLS und schließt mit einer kommentierten Anmerkungs- und Literaturliste für die weitere Beschäftigung mit Ontologien.

Content

Dieser Aufsatz ist kein Abgesang auf MeSH (= Medical Subject Headings in Medline/PubMed), wie man/frau vielleicht vermuten könnte. Vielmehr wird - ohne informatiklastiges Fachchinesisch - an Hand des von der National Library of Medicine entwickelten Unified Medical Language System erklärt, worin die Anforderungen an Ontologien bestehen, die im Zusammenhang mit dem Semantic Web allerorten eingefordert und herbeigewünscht werden. Eine Lektüre für Einsteigerinnen, die zum Vertiefen der gewonnenen Begriffssicherheit an Hand der weiterführenden Literaturhinweise anregt. Da das UMLS hier vor allem als Beispiel verwendet wird, werden auch Bibliothekarlnnen, Dokumentarlnnen und Informationsspezialistinnen anderer Fachbereiche den Aufsatz mit Gewinn lesen - und erfahren, dass unser Fachwissen aus der Sacherschließung und der Verwendung und Mitgestaltung von Normdateien und Thesauri bei der Entwicklung von Ontologien gefragt ist!

Abstract

The Alexandria Digital Library Project announces the online publication of two protocols to support querying and response interactions using distributed services: one for gazetteers and one for thesauri. These protocols have been developed for our own purposes and also to support the general interoperability of gazetteers and thesauri on the web. See <http://www.alexandria.ucsb.edu/~gjanee/gazetteer/> and <http://www.alexandria.ucsb.edu/~gjanee/thesaurus/>. For the gazetteer protocol, we have provided a page of test forms that can be used to experiment with the operational functions of the protocol in accessing two gazetteers: the ADL Gazetteer and the ESRI Gazetteer (ESRI has participated in the development of the gazetteer protocol). We are in the process of developing a thesaurus server and a simple client to demonstrate the use of the thesaurus protocol. We are soliciting comments on both protocols. Please remember that we are seeking protocols that are essentially "simple" and easy to implement and that support basic operations - they should not duplicate all of the functions of specialized gazetteer and thesaurus interfaces. We continue to discuss ways of handling various issues and to further develop the protocols. For the thesaurus protocol, outstanding issues include the treatment of multilingual thesauri and the degree to which the language attribute should be supported; whether the Scope Note element should be changed to a repeatable Note element; the best way to handle the hierarchical report for multi-hierarchies where portions of the hierarchy are repeated; and whether support for searching by term identifiers is redundant and unnecessary given that the terms themselves are unique within a thesaurus. For the gazetteer protocol, we continue to work on validation of query and report XML documents and on implementing the part of the protocol designed to support the submission of new entries to a gazetteer. We would like to encourage open discussion of these protocols through the NKOS discussion list (see the NKOS webpage at <http://nkos.slis.kent.edu/>) and the CGGR-L discussion list that focuses on gazetteer development (see ADL Gazetteer Development page at <http://www.alexandria.ucsb.edu/gazetteer>).
