- Abstract
- A software system has been developed which orders citations retrieved from an online database in terms of relevancy. The system resulted from an effort generated by NASA's Technology Utilization Program to create new advanced software tools to largely automate the process of determining relevancy of database citations retrieved to support large technology transfer studies. The ranking is based on the generation of an enriched vocabulary using lexical association methods, a user assessment of the vocabulary and a combination of the user assessment and the lexical metric. One of the key elements in relevancy ranking is the enriched vocabulary -the terms mst be both unique and descriptive. This paper examines term uniqueness. Six lexical association methods were employed to generate characteristic word indices. A limited subset of the terms - the highest 20,40,60 and 7,5% of the uniquess words - we compared and uniquess factors developed. Computational times were also measured. It was found that methods based on occurrences and signal produced virtually the same terms. The limited subset of terms producedby the exact and centroid discrimination value were also nearly identical. Unique terms sets were produced by teh occurrence, variance and discrimination value (centroid), An end-user evaluation showed that the generated terms were largely distinct and had values of word precision which were consistent with values of the search precision.

- Arguing that catalogers need to work both quickly and accurately, Bade maintains that employing specialists is the most efficient and effective way to achieve this outcome. Far less compelling than these arguments are Bade's concluding remarks, in which he offers meager suggestions for correcting the problems as he sees them. Overall, this essay is little more than a curmudgeon's diatribe. Addressed primarily to catalogers and library administrators, the analysis presented is too superficial to assist practicing catalogers or cataloging managers in developing solutions to any systemic problems in current cataloging practice, and it presents too little evidence of pervasive problems to convince budget-conscious library administrators of a need to alter practice or to increase their investment in local cataloging operations. Indeed, the reliance upon anecdotal evidence and the apparent nit-picking that dominate the essay might tend to reinforce a negative image of catalogers in the minds of some. To his credit, Bade does provide an important reminder that it is the intellectual contributions made by thousands of erudite catalogers that have made shared cataloging a successful strategy for improving cataloging efficiency. This is an important point that often seems to be forgotten in academic libraries when focus centers an cutting costs. Had Bade focused more narrowly upon the issue of deintellectualization of cataloging and written a carefully structured essay to advance this argument, this essay might have been much more effective." - KO 29(2002) nos.3/4, S.236-237 (A.

- Abstract
- Purpose - The purpose of this paper is to examine the effect of the Helping Interdisciplinary Vocabulary Engineering (HIVE) system on the inter-indexer consistency of information professionals when assigning keywords to a scientific abstract. This study examined first, the inter-indexer consistency of potential HIVE users; second, the impact HIVE had on consistency; and third, challenges associated with using HIVE. Design/methodology/approach - A within-subjects quasi-experimental research design was used for this study. Data were collected using a task-scenario based questionnaire. Analysis was performed on consistency results using Hooper's and Rolling's inter-indexer consistency measures. A series of t-tests was used to judge the significance between consistency measure results. Findings - Results suggest that HIVE improves inter-indexing consistency. Working with HIVE increased consistency rates by 22 percent (Rolling's) and 25 percent (Hooper's) when selecting relevant terms from all vocabularies. A statistically significant difference exists between the assignment of free-text keywords and machine-aided keywords. Issues with homographs, disambiguation, vocabulary choice, and document structure were all identified as potential challenges. Research limitations/implications - Research limitations for this study can be found in the small number of vocabularies used for the study. Future research will include implementing HIVE into the Dryad Repository and studying its application in a repository system. Originality/value - This paper showcases several features used in HIVE system. By using traditional consistency measures to evaluate a semantic web technology, this paper emphasizes the link between traditional indexing and next generation machine-aided indexing (MAI) tools.
