- Abstract
- The frequency of non-informative titles of journal articles was assessed for two fields: library and information science and sociology. The percentage of non informative titles was 21% in the formaer and 15% in the latter. In both fields, the non-informative titles, were concentratein only a few journals. The non-informative titles in library science were derived mainly from non-research journals. IN sociology the reasons for non-informative titles may be more complex; some of these journals are highly cited. For the improvement of retrievaleffiency the adoption of a policy encouraging informative titles (as in journals of chemistry) is recommended.

- Eine fundierte Untersuchung der Anforderungen an Experimente im Information Retrieval bedarf einer geeigneten Sprache, die es erlaubt, alle relevanten Aspekte adäquat zu beschreiben. Der Beitrag versucht, ein solches Begriffsgerüst zu entwickeln. Als grundlegende Begriffe dienen die 4 Kategorien: experimentelle Faktoren, situative Faktoren; Experimentalobjekte und Beobachtungsvariablen. Das Begriffsgerüst wird anhand praktischer Beispiele illustriert

- Abstract
- A study was done to test the effectiveness of retrieval using title word searching. It was based on actual search profiles used in the Mechanized Information Center at Ohio State University, in order ro replicate as closely as possible actual searching conditions. Fewer than 50% of the relevant titles were retrieved by keywords in titles. The low rate of retrieval can be attributes to three sources: titles themselves, user and information specialist ignorance of the subject vocabulary in use, and to general language problems. Across fields it was found that the social sciences had the best retrieval rate, with science having the next best, and arts and humanities the lowest. Ways to enhance and supplement keyword in title searching on the computer and in printed indexes are discussed.

- Abstract
- Searches conducted as part of the MEDLINE/Full-Text Research Project revealed that the full-text data bases of clinical medical journal articles (CCML (Comprehensive Core Medical Library) from BRS Information Technologies, and MEDIS from Mead Data Central) did not retrieve all the relevant citations. An analysis of the data indicated that 204 relevant citations were retrieved only by MEDLINE. A comparison of the strategies used on the full-text data bases with the text of the articles of these 204 citations revealed that 2 reasons contributed to these failure. The searcher often constructed a restrictive strategy which resulted in the loss of relevant documents; and as in other kinds of retrieval, the problems of natural language caused the loss of relevant documents.

- Abstract
- Paper presented at the 30th Annual Conference of the National Federation of Astracting and Information Services, Philadelphia, 28 Feb-2 Mar 88. In recent years, the amount and the variety of available machine-readable data, new technologies have been introduced, such as high density storage devices, and fancy graphic displays useful for information transformation and access. New approaches have also been considered for processing the stored data based on the construction of knowledge bases representing the contents and structure of the information, and the use of expert system techniques to control the user-system interactions. Provides a brief evaluation of the new information processing technologies, and of the software methods proposed for information manipulation.

- Abstract
- An experiment was conducted using 3 data bases in library and information science - Library and Information Science Abstracts (LISA), Information Science Abstracts and ERIC - to investigate some of the main factors affecting on-line searching: effectiveness of search vocabularies, combinations of fields searched, and overlaps among databases. Natural language, controlled vocabulary and a mixture of natural language and controlled terms were tested using different fields of bibliographic records. Also discusses a comparative evaluation of single and multi-data base searching, measuring the overlap among data bases and their influence upon on-line searching.
