- Abstract
- The application of thesauri in networked environments is seriously hampered by the challenges of introducing new concepts and terminology into the formal controlled vocabulary, which is critical for enhancing its retrieval capability. The author describes an automated process of adding new terms to thesauri as entry vocabulary by analyzing the association between words/phrases extracted from bibliographic titles and subject descriptors in the metadata record (subject descriptors are terms assigned from controlled vocabularies of thesauri to describe the subjects of the objects [e.g., books, articles] represented by the metadata records). The investigated approach uses a corpus of metadata for scientific and technical (S&T) publications in which the titles contain substantive words for key topics. The three steps of the method are (a) extracting words and phrases from the title field of the metadata; (b) applying a method to identify and select the specific and meaningful keywords based on the associated controlled vocabulary terms from the thesaurus used to catalog the objects; and (c) inserting selected keywords into the thesaurus as new terms (most of them are in hierarchical relationships with the existing concepts), thereby updating the thesaurus with new terminology that is being used in the literature. The effectiveness of the method was demonstrated by an experiment with the Chinese Classification Thesaurus (CCT) and bibliographic data in China Machine-Readable Cataloging Record (MARC) format (CNMARC) provided by Peking University Library. This approach is equally effective in large-scale collections and in other languages.

- Abstract
- Der Thesaurus als Dokumentationssprache wird in der DIN 1463-1in seinen wesentlichen Merkmalen beschrieben. Dort wird der Thesaurus im informationswissenschaftlichen Sinne so definiert: "Ein Thesaurus im Bereich der Information und Dokumentation ist eine geordnete Zusammenstellung von Begriffen und ihren (vorwiegend natürlichsprachigen) Bezeichnungen, die in einem Dokumentationsgebiet zum Indexieren, Speichern und Wiederauffinden dient. Er ist durch folgende Merkmale gekennzeichnet: a) Begriffe und Bezeichnungen werden eindeutig aufeinander bezogen ("terminologische Kontrolle"), indem - Synonyme möglichst vollständig erfasst werden, - Homonyme und Polyseme besonders gekennzeichnet werden, - für jeden Begriff eine Bezeichnung (Vorzugsbenennung, Begriffsnummer oder Notation) festgelegt wird, die den Begriff eindeutig vertritt, b) Beziehungen zwischen Begriffen (repräsentiert durch ihre Bezeichnungen) werden dargestellt." Diese Definition wäre zu ergänzen um folgende: c) Der Thesaurus ist präskriptiv, indem er für seinen Geltungsbereich festlegt, welche begrifflichen Einheiten zur Verfügung gestellt werden und durch welche Bezeichnungen diese repräsentiert werden. Im Folgenden sollen die wichtigsten Elemente und Prinzipien von Thesauri und die Thesaurusmethodik vorgestellt werden. Dies kann in diesem Rahmen nur auf eine sehr kursorische und allgemeine Art und Weise geschehen. Außerdem beschränkt sich die Darstellung auf den Thesauruseinsatz im klassischen Bereich von Information und Dokumentation. Auf die Behandlung von Spezialproblemen oder auf besondere Thesaurusformen (z.B. mehrsprachige Thesauri) kann hier nicht eingegangen werden, ebenso auf die erweiterten Anforderungen, die an Thesauri im Kontext von Wissensrepräsentation oder Hypertext zu stellen sind. Allerdings überschneidet sich der klassische IuD-Bereich zunehmend mit erweiterten Formen (etwa im Rahmen von Internetanwendungen). Da der Thesaurus im dokumentarischen Sinn alle Grundelemente des Thesaurusprinzips in klarer Form aufweist, wird dieser Bereich für eine Einführung gewählt. Für eine intensivere Auseinandersetzung mit der Thematik wird die Lektüre von Wersig empfohlen, auf den sich auch die folgenden Ausführungen in weiten Teilen stützen. Eine weitere grundsätzliche Einführung in diesen Bereich, allerdings eher ausgerichtet auf die Spezifika des englischen Sprachraums, findet sich bei Lancaster.

- Abstract
- Calvin Mooers' work toward the resolution of the problem of ambiguity in indexing went unrecognized for years. At the time he introduced the "descriptor" - a term with a very distinct meaning-indexers were, for the most part, taking index terms directly from the document, without either rationalizing them with context or normalizing them with some kind of classification. It is ironic that Mooers' term came to be attached to the popular but unsophisticated indexing methods which he was trying to root out. Simply expressed, what Mooers did was to take the dictionary definitions of terms and redefine them so clearly that they could not be used in any context except that provided by the new definition. He did, at great pains, construct such meanings for over four hundred words; disambiguation and specificity were sought after and found for these words. He proposed that all indexers adopt this method so that when the index supplied a term, it also supplied the exact meaning for that term as used in the indexed document. The same term used differently in another document would be defined differently and possibly renamed to avoid ambiguity. The disambiguation was achieved by using unabridged dictionaries and other sources of defining terminology. In practice, this tends to produce circularity in definition, that is, word A refers to word B which refers to word C which refers to word A. It was necessary, therefore, to break this chain by creating a new, definitive meaning for each word. Eventually, means such as those used by Austin (q.v.) for PRECIS achieved the same purpose, but by much more complex means than just creating a unique definition of each term. Mooers, however, was probably the first to realize how confusing undefined terminology could be. Early automatic indexers dealt with distinct disciplines and, as long as they did not stray beyond disciplinary boundaries, a quick and dirty keyword approach was satisfactory. The trouble came when attempts were made to make a combined index for two or more distinct disciplines. A number of processes have since been developed, mostly involving tagging of some kind or use of strings. Mooers' solution has rarely been considered seriously and probably would be extremely difficult to apply now because of so much interdisciplinarity. But for a specific, weIl defined field, it is still weIl worth considering. Mooers received training in mathematics and physics from the University of Minnesota and the Massachusetts Institute of Technology. He was the founder of Zator Company, which developed and marketed a coded card information retrieval system, and of Rockford Research, Inc., which engages in research in information science. He is the inventor of the TRAC computer language.
