- Abstract
- 'Information at your fingertip' ist einer der großen Versprechen der Computerindustrie. Tatsächlich wächst das Angebot online verfügbarer Datenbanken und Informationsnetze mit geradezu atemberaubender Geschwindigkeit. Waren Online-Recherchen noch vorwenigen Jahren eine teure Spielerei für Experten, so kann sich heute jeder in den Netzen auf die Suche begeben. Doch ohne Know-how werden die Ergebnisse kaum befriedigen. Dieses Buch hilft Ihnen, die Recherchekosten und den Arbeitsaufwand so niedrig wie möglich zu halten. Es vermittelt die notwendigen Kenntnisse im Umgang mit Online-Diensten und dem Internet und erläutert die Besonderheiten der unterschiedlichen Datenbanken. Vor allem aber erklärt es anhand praxisnaher Beispiele, wie man Suchanfragen konzipiert und erfolgversprechende Suchstrategien entwickelt

- Abstract
- Describes and evaluates the proximity search facilities in external online systems and in-house retrieval software. Discusses and illustrates capabilities, syntax and circumstances of use. Presents measurements of the overheads required by proximity for storage, record input time and search time. The search strategy narrowing effect of proximity is illustrated by recall and precision test results. Usage and problems lead to a number of design ideas for better implementation: some based on existing Boolean strategies, one on the use of weighted proximity to automatically produce ranked output. A comparison of Boolean, quorum and proximate term pairs distance is included

- Abstract
- This paper describes a new OPAC system called The Book House and discusses its relevance as a solution to current OPAC developments. The Book House is an interactive, multimedia, online public access catalogue system designed to support casual and/or novice end-users in information retrieval. It runs on a Macintosh and is available on CD-ROM and disks in English and Danish (it can be purchased from Risø for $100). It comprises an interface and module for classifying and indexing fact and fiction books in the database called Book House Write. It uses icons, text and animation in the display interface in order to enhance the utility of the system for the general public. Both words and pictures can be used for searching, which makes the system suitable for all age groups. It plays on users' previous experiencees with computer games to support learning by doing something in an enjoyable way. A prerequisite for the design of The Book House was a new approach to cognitive analysis of retrieval in libraries. Based on the success of this approach, it is claimed that OPAC systems will only be really useful and widespread (1) when their domain and task characteristics allow supplementary information to be added to existing descriptions of book content in online card catalogues in order to match end-users' intentions and needs, and (2) when the user interface and routes to the databases are configured as an integrated and uniform set of displays which match the search strategies of users, as well as their mental capabilities and limitations

- Abstract
- Reports on a study of the search tactics used in searching the WWW and in dealing with difficulties such as too many postings and no relevant postings. Describes how the study was carried out, the analytical techniques used in it, and the results. Notes that with regard to tactics used to address search difficulties, no differences were found between searchers for texts and those for graphic information, and between those for known items and subject searches. Comments on the similarities and differences between the tactics used and and those used in online searching, including online catalogue searching

- Abstract
- Discusses the results of a survey sent to online searchers in the United Kingdom, USA, Australia and Canada. The purpose of the study was to investigate the influence of national culture on information retrieval skills. The survey form provided a sample question and asked searchers to prepare a preliminary strategy for a search on the Sociological Abstracts online database. Cultural patterns to online searching were discerned. American searchers were found to depend on controlled vocabulary much more than British searchers. Australian searchers seemed to have created a search style of their own, while Canadian searchers blended the American and British patterns. In reviewing results of the searches, over half of the citations retrieved were retrieved by more than one search. Australian searchers were more likely to retrieve items that no other search retrieved, while Canadian searchers had the highest overlap rate. If the theory that citations retrieved by the most searches are the most relevant is correct, then the Canadian searchers prepare the best searches. The Canadian searchers also seemed to be the most international, as their search results overlapped with those from the other 3 countires more often than did searches from other countries. One question contained in the survey asked searchers to suggest related databases for their searches. PAIS and SSCI were the databases mentioned most often in all 4 countires. Nevertheless, cultural differences and ethnocriticism could be discerned in the results with searchers listing databases specifically relating to their own countries or regions: Australian PAIS and US Political Science Abstracts being 2 examples

- Abstract
- Information retrieval systems based on the Boolean model have been popular for some time. A major challenge to this model has come from the development of approaches based on the vector processing model. Both search strategies are explained and evaluated. Describes an experimental study in an opertational environment to compare the retrieval effectiveness of Boolean and nearest neighbour searching in a multi-strategy retrieval system based on query characteristic variables. Considers the significance of the results of the study

- Abstract
- Considers what elicitation or requests for information search intermediaries make of users with information requests during an information retrieval interaction - including prior to and during an information retrieval interaction - and for what purpose. Reports a study of elicitations during 40 mediated information retrieval interactions. Identifies a total of 1.557 search intermediary elicitations within 15 purpose categories. The elicitation purposes of search intermediaries included requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous information seeking. Investigates the transition sequences from 1 type of search intermediary elicitation to another. Compares these findings with results from a study of end user questions

- Abstract
- To be successful at online searching, students must be able to apply the concepts and skills learned in the classroom to a variety of complex products and search conditions. Examines an online searching instructional programme for high school seniors from the perspective of several cognitive learning theories, and proposes a synthesized approach to applying learning theory to bibliographic instruction

- Abstract
- As end users perform their own searches, more insight into their searching behaviour is needed. Identifies and describes the strategies, assessments and affective behaviours from the transcripts and keystroke records collected during 3 searches. The affective behaviours exhibited by the searchers show the involvement of other than cognitive activities in this intellectual pursuit. Particularly interesting is the single mindedness of the search strategies. Describes the searchers' online assessments of the usefulness of retrieved records including assessment strategies that were developed

- Abstract
- UK and USA textbooks present keyword and controlled vocabulary searching in different ways, and put differing emphasis on the use of variant spellings and word variations. This reflects previous research on the way searchers in the 2 countries prepare online search strategies. Differences may reflect occupational trends, cultural behaviour, or awareness of a greater world view

- Abstract
- To become lifelong learners, students must acquire information retrieval skills for future as well as current information needs. Describes how the library use instruction programme at Northwest Missouri State University incorporates a heuristic model in which students continually evaluate and refine their information seeking practices while progressing through all levels of courses in diverse disciplines. Collegial partnerships with departmental faculty and ongoing instructional assessment are essential to the success of the programme
