    Abstract
    Ein neuer internationaler Standard der Information und Dokumentation - Thesauri and interoperability with other vocabularies (ISO 25964) ist in Vorbereitung. Part 1: Thesauri for information retrieval wurde Mitte August als DIS 25964-1 im ISO Central Secretariat eingereicht. Die Motivation zur Entwicklung eines neuen Vokabularstandards sowie die wesentlichen Änderungen und Erweiterungen gegenüber ISO 2788/ISO 5964 werden vorgestellt. Anhand des Datenmodells zu Part 1: Thesauri for information retrieval werden die grundlegenden Elemente, Attribute und Relationen kurz erläutert. Mit der Arbeit an Part 2: Interoperability with other vocabularies wurde Ende Juni 2009 begonnen. Es sollen Richtlinien erarbeitet werden, um Interoperabilität zwischen Thesauri und anderen Vokabularien wie Normdateien für Namen, Schlagwortlisten, Ontologien, Klassifikationen und dgl. zu gewähren. Der erste Commitee Draft (CD 25964-2) ist für Juni 2010 geplant. Über den Stand der Entwicklung des 2. Teiles wird kurz referiert.

    Abstract
    The biomedical book collection in the Genetech Library and Information Services was first inventoried and cataloged in 1983 when it totaled about 2000 titles. Cataloging records were retrieved from the OCLC system and used as a basis for cataloging. A year of cataloging produced a list of 1900 subject terms. More than one term describing the same concept often appears on the list, and no hierarchical structure related the terms to one another. As the collection grew, the subject catalog became increasingly inconsistent. To bring consistency to subject cataloging, a thesaurus of biomedical terms was constructed using the list of subject headings as a basis. This thesaurus follows the broad categories of the National Library of Medicine's Medical Subject Headings and, with some exceptions, the Guidelines for the Establishment and Development of Monolingual Thesauri. It has enabled the cataloger in providing greater in-depth subject analysis of materials added to the collection and in consistently assigning subject headings to cataloging record.

    Abstract
    Describes a consultancy project for the development of a health care thesaurus involving the movement of text between different application programs. The thesaurus was built from existing text within the organisation originating from 3 sources: natural language registry file headings; descriptions from an internal business directory and a controlled vocabulary. The software used was WordPerfect and Cardbox

    Abstract
    Connecting and evaluating thesauri is an important task for the systematic development of better information retrieval systems. Connecting thesauri includes not only determining when terms in different thesauri are the same but also determining what kinds of relationships can be transferred from one thesaurus to another. This paper first presents issues in connecting and evaluating thesauri. Various experiments in connecting a particular thesaurus, the Medical Subject Headings, with other medical thesauri are described. In these experiments, similar terms in two thesauri are recognized and then differences in two thesauri are exploited to create more powerful thesauri. Part of the evaluation requires the thesaurus to support automatic indexing and retrieving of documents

    Abstract
    LCSH is known as such since 1975. It always has created headings to serve the LC collections instead of a theoretical basis. It started to replace cross reference codes by thesaural codes in 1986, in a mechanical fashion. It was in no way transformed into a thesaurus. Its encyclopedic coverage, its pre-coordinate concepts make it substantially distinct, considering that thesauri usually map a restricted field of knowledge and use uniterms. The questions raised are whether the new symbols comply with thesaurus standards and if they are true to one or to several models. Explanations and definitions from other lists of subject headings and thesauri, literature in the field of classification and subject indexing will provide some answers. For instance, see refers from a subject heading not used to another or others used. Exceptionally it will lead from a specific term to a more general one. Some equate a see reference with the equivalence relationship. Such relationships are pointed by USE in LCSH. See also references are made from the broader subject to narrower parts of it and also between associated subjects. They suggest lateral or vertical connexions as well as reciprocal relationships. They serve a coordination purpose for some, lay down a methodical search itinerary for others. Since their inception in the 1950's thesauri have been devised for indexing and retrieving information in the fields of science and technology. Eventually they attended to a number of social sciences and humanities. Research derived from thesauri was voluminous. Numerous guidelines are designed. They did not discriminate between the "hard" sciences and the social sciences. RT relationships are widely but diversely used in numerous controlled vocabularies. LCSH's aim is to achieve a list almost free of RT and SA references. It thus restricts relationships to BT/NT, USE and UF. This raises the question as to whether all fields of knowledge can "fit" in the Procrustean bed of RT/NT, i.e., genus/species relationships. Standard codes were devised. It was soon realized that BT/NT, well suited to the genus/species couple could not signal a whole-part relationship. In LCSH, BT and NT function as reciprocals, the whole-part relationship is taken into account by ISO. It is amply elaborated upon by authors. The part-whole connexion is sometimes studied apart. The decision to replace cross reference codes was an improvement. Relations can now be distinguished through the distinct needs of numerous fields of knowledge are not attended to. Topic inclusion, and topic-subtopic, could provide the missing link where genus/species or whole/part are inadequate. Distinct codes, BT/NT and whole/part, should be provided. Sorting relationships with mechanical means can only lead to confusion.

    Abstract
    This paper describes an ongoing project in which the subject headings contained in twelve controlled vocabularies covering multiple disciplines from the humanities to the sciences and including law and education among others are being collapsed into a single vocabulary and reference structure. The design of the database, algorithms created to programmatically link like-concepts, and daily maintenance are detailed. The problems and pitfalls of dealing with multiple vocabularies are noted, as well as the difficulties in relying purely an computer generated algorithms. The application of this megathesaurus to bibliographic records and methodology of retrieval is explained.

    Abstract
    The MACS (Multilingual access to subjects) project is one of the many projects that are currently exploring solutions to multilingual subject access to online catalogs. Its strategy is to develop a Web based link and search interface through which equivalents between three Subject Heading Languages: SWD/RSWK (Schlagwortnormdatei/Regeln für den Schlagwortkatalog) for German, RAMEAU (Repertoire d'Autorite-Matière Encyclopedique et Alphabetique Unifie) for French and LCSH (Library of Congress Subject Headings) for English can be created and maintained, and by which users can access online databases in the language of their choice. Factors that have lead to this approach will be examined and the MACS linking strategy will be explained. The trend to using mapping or linking strategies between different controlled vocabularies to create multilingual access challenges the traditional view of the multilingual thesaurus.

    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
    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."

    Footnote
    The didactic parts of the book are a collection of exercises, readings and resources constituting a "Teach yourself " chapter written by Alan Thomas, ending with the warning that "New challenges include how to devise multi-functional and usersensitive vocabularies, corporate taxonomies and ontologies, and how to apply the transformative technology to them." This is absolutely right, and there is a need for some good writing that would tackle these issues. Another chapter, by James Shearer, skilfully manages to compress a practical exercise in building a thesaurus into some twenty A5 size pages. The third chapter in this set, by Marianne Lykke Nielsen, contains extensive reviews of key issues and selected readings under eight headings from the concept of the thesaurus, through the various construction stages and ending with automatic construction techniques. . . . This is a useful and approachable book. It is a pity that the index is such a poor advertisement for vocabulary control and usefulness."

    Abstract
    When consumers search for health information, a major obstacle is their unfamiliarity with the medical terminology. Even though medical thesauri such as the Medical Subject Headings (MeSH) and related tools (e.g., the MeSH Browser) were created to help consumers find medical term definitions, the lack of direct and explicit integration of these help tools into a health retrieval system prevented them from effectively achieving their objectives. To explore this issue, we conducted an empirical study with two systems: One is a simple interface system supporting query-based searching; the other is an augmented system with two new components supporting MeSH term searching and MeSH tree browsing. A total of 45 subjects were recruited to participate in the study. The results indicated that the augmented system is more effective than the simple system in terms of improving user-perceived topic familiarity and question-answer performance, even though we did not find users spend more time on the augmented system. The two new MeSH help components played a critical role in participants' health information retrieval and were found to allow them to develop new search strategies. The findings of the study enhanced our understanding of consumers' search behaviors and shed light on the design of future health information retrieval systems.
