Abstract

Discusses the theory and practice of bibliographic control, provides a definition for a bibliographic centre and for bibliographic control in a national bibliographic centre, and discusses the current situation and future development in bibliographic control in the national bibliographic centre (of China). Makes some suggestions for planning effective bibliographic control in the national bibliographic centre as follows: to collect materials; to recruit advisers; to set up a mission, goals and objectives; to make and implement action plans; to put in place the organizational structure of the bibliographic database; and to make plans for cooperating with other area or national bibliographic centres

Abstract: Bibliographic(al) control is important for retrieving documents in the library. Reviews previous studies in order to understand bibliographic(al) control from its very beginnings up to the present information age. The history, meaning, scope and functions of bibliographic(al) control are included. Finally, various catalogues are reviewed and discussed

Abstract

Uses an information processing approach to analyse the behaviour of end users in searching online bibliographic databases, with particular emphasis on errors made. Following instruction in online searching, 41 students and 3 faculty end users conducted 79 subject searches. Analysis of search transcripts identified 119 reasons for errors. Errors occured most frequently in connection with functions, moves, and elements of 'create and develop sets' and 'display and print records'. Surprisingly, the results do not indicate that end users make errors less frequently as they gain more experience and practice, although syntax-related errors do decrease with time

Abstract

One of the major causes of search failures in information retrieval systems is vocabulary mismatch. Presents a solution to the vocabulary problem through 2 strategies known as term suggestion (TS) and term relevance feedback (TRF). In TS, collection specific terms are extracted from the text collection. These terms and their frequencies constitute the keyword database for suggesting terms in response to users' queries. One effect of this term suggestion is that it functions as a dynamic directory if the query is a general term that contains broad meaning. In term relevance feedback, terms extracted from the top ranked documents retrieved from the previous query are shown to users for relevance feedback. In the experiment, interactive TS provides very high precision rates while achieving similar recall rates as n-gram matching. Local TRF achieves improvement in both precision and recall rate in a full text news database and degrades slightly in recall rate in bibliographic databases due to the very limited source of information for feedback. In terms of Rijsbergen's combined measure of recall and precision, both TS and TRF achieve better performance than n-gram matching, which implies that the greater improvement in precision rate compensates the slight degradation in recall rate for TS and TRF
