Abstract

Reports the work of the Centre for Information Quality Management, UK, (CIQM), in improving database quality. Discusses general database quality issues, the database labelling concept advocated by CIQM (a mini specification which contains parameters which measure the database as it now is), and progress in encouraging database producers to use labelling to accredit their databases

Abstract

Discusses the application of the Platform for Internet Content Selection (PICS) methodology, developed in response to the US Communications Decency Act, 1996 (to enable indecent sites to be circumnavigated), as a means of labelling databases, particularly those incorporating metadata. Describes the potential for PICS in the labelling and describing of databases available via the Internet and WWW. Notes the place of PICS in relation to the activities and recommendations of the Centre for Information Quality Management

Abstract

Reports on one area of research in an Electronic Libraries Programme (eLib) MODELS (MOving to Distributed Environments for Library Services) supporting study in 3 investigative areas: examination of current database producers' guidelines for their abstract writers; a brief survey of abstracts in some traditional online databases; and a detailed survey of abstracts from 3 types of electronic database (print sourced online databases, Internet subject trees or directories, and Internet gateways). Examination of database producers' guidelines, reported here, gave a clear view of the intentions behind professionally produced traditional (printed index based) database abstracts and provided a benchmark against which to judge the conclusions of the larger investigations into abstract style, readability and content

Abstract

Following a brief introduction to the history of online and online training, surveys current training from the point of view of the trainers, the trainees and the media. Deals in depth with computer-assisted instruction for online searching with examples drawn from a number of available packages. Some of the techniques, such as self-testing and search simulations, as well as the advantages of this method of instruction are discussed

Abstract

Discusses the kind of database quality problems regularly encountered. Describes the work currently being undertaken in this field by EUSIDIC (European Association of Information Services), by SCOUG (Southern California Online User Group) and by the Centre for Information Quality Management (CIQM) itself, which is investigating the idea of database labelling as a solution to the quality issue

Abstract

Discusses the issue of quality as applied to databases. Describes the role of the Centre for Information Quality Management (CIQM) set up by the Library Association and the UK Online User Group (UKOLUG), in acting as a clearing house to which database users could report problems relating to the quality of any aspect of a database being used. The Centre compiles statistics on database quality issues which can then be forwarded to the database producers and hosts. Champions the use of standardized database labels which include not only basic information about the database but also a quality assurance statement

Abstract

Abstracts from 7 Internet subject trees (Euroferret, Excite, Infoseek, Lycos Top 5%, Magellan, WebCrawler, Yahoo!), 5 Internet subject gateways (ADAM, EEVL, NetFirst, OMNI, SOSIG), and 3 online databases (ERIC, ISI, LISA) were examined for their subject content, treatment of various enriching features, physical properties such as overall length, anf their readability. Considerable differences were measured, and consistent similarities among abstracts from each type of source were demonstrated. Internet subject tree abstracts were generally the shortest, and online database abstracts the longest. Subject tree and online database abstracts were the most informative, but the level of coverage of document features such as tables, bibliographies, and geographical constraints were disappointingly poor. On balance, the Internet gateways appeared to be providing the most satisfactory abstracts. The authors discuss the continuing role in networked information retrieval of abstracts and their functional analoques such as metadata
