UDC in subject Subject Gateways: Experiment or Opportunity?

AbstractThe paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.

Improving Information Retrieval of Subjects Through Citation-Analysis

Abstract Citation-chasing is proposed as a method of discovering additional terms to enhance subject-search retrieval by broadening and prioritizing the results. Subjects attached to records representing cited works are compared to subjects attached to records representing the original citing sources, and to the subjects yielded by chasing see-also references from the latter group of headings. Original citing sources were yielded via a subject-list search in a library catalog using the subject heading “Language and languages – Origin.” A subject-search was employed to avoid subjectivity in choosing sources. References from the sources were searched in OCLC where applicable, and the subject headings were retrieved. The subjects were ranked first by number of citations from original sources, then by total citation- frequency. The results were tiered into 4 groups in a Bradford-like distribution. A similar rank and division was performed on the subjects representing the original citing sources, and those yielded by chasing see-also references. Both in terms of subject frequency and topic type, positive comparisons between citation chasing and see-also references show a confirmation of different methods of yielding alternative subjects. Exclusive results suggest potential mutual complementary value among these different methods.

Terminology Structure for Learner's Glossaries

AbstractThis study presents a methodology for compiling corpus-based learner’s glossaries designed for nonspecialist translators and LSP learners. The need for such bilingual microglossaries on subsections of a subject field for LSP teaching and translation purposes is emphasized in the Introduction. The concept ‘learner’s glossary’ is delimited among other types of terminological collections such as a specialised dictionary, a thesaurus and a term bank in Section 2 where the information categories in an entry are specified (keyterm plus translation equivalent(s), definition of keyterm and exemplary context, narrower terms with synonyms, definitions and translation equivalents; special phrases based on keyterm collocations with translation equivalents and exemplary contexts). Section 3 describes the principles and working methods of modern terminography as well as the source materials available for the glossary compilation. A hybrid term extraction technique is also described in that section and is used to extract the candidate terms with subsequent manual initial processing of the results. In Section 4 the theoretical grounds and methodology for analysing the conceptual relations in a terminological system are presented including the expert validation of the automatically extracted terms as a first phase in that process. Rationale for applying a lexico-semantic analysis in identifying collocational information on the keyterms is provided in Section 5 which is proposed to involve descriptions of the actantial structure of a keyterm for identifying verbal (T+V) collocations and of the paradigmatic and syntagmatic morpho-syntactic relations applicable to a keyterm. Finally, a model for structuring a learner's glossary entry is proposed in Section 6.
