    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
    The Art and Architecture Thesaurus (AAT) was designed as a comprehensive vocabulary in its domain. Its faceted, hierarchically arranged structure allows for powerful indexing and retrieval capabilities, while its planned network of related term relationships makes it especially amenable to natural language processing. To gauge the AAT's effectiveness as a search tool against natural language queries, an experiment was carried out on DIALOG. There are 3 art data bases on DIALOG and there are also a number of other data bases that contain art related material. The experiment used queries culled from reference librarians at art and architecture libraries.

    Abstract
    Problems of indexing and searching free-text data bases are discussed in detail. The possibilities and limitations of Boolean searching are shown. An experimental system COPSY (Context operator syntax) that was built in order to avoid common errors connected with Boolean search is outlined. This system permits, as input, any natural language search question formulation and yields, as output, documents ranked on the basis of an automatically calculated correspondence between natural language search questions and content-based analysis of documents. COPSY is part of a text processing project at Siemens AG called TINA (Text-Inhalts-Analyse...). Software from TINA is actually being applied and evaluated by the US Department of Commerce for patent searching and indexing.

    Abstract
    Although thesauri can be solve some problems posed by computerised data base searching (synonyms, generic representation) their compilation requires extensive time and effort of experts and their maintenance is also difficult. Describes how a thesaurus was compiled and maintained automatically by taking advantage of the specially designed formats to input expertise with ease. The thesaurus was named a dynamic thesaurus because it depends on the set of stored data and is adapted to the necessary and sufficient range of keywords. A data base of polymers is taken as an example.

    Abstract
    The availability of two full text data bases in the clinical medical journal literature, MEDIS from Mead Data Central and CCML from BRS Information Technologies, provided an opportunity to compare the efficacy of the full text to the traditional, indexed system, MEDLINE for retrieval effectiveness. 100 searches were solicited from an academic health sciences library and the request were searched on all 3 data bases. The results were compared and preliminary analysis suggests that the full text data bases retrieve a greater number of relevant citations and MEDLINE achieves higher precision.

    Abstract
    40 doctoral student were trained to search INSPEC or ERIC on DIALOG using either the Sci-Mate Menu or native commands. In comparison with 20 control subjects for whom a free search was performed by an intermediary, the experiment subjects were no less satisfied with their retrievals, which were fewer in number but higher in precision than the retrievals produced by the intermediaries. Use of the menu interface did not affect quality of retrieval or user satisfaction, although subjects instructed to use native commands required less training time and interacted more with the data bases than did subjects trained on the Sci-Mate Menu. INSPEC subjects placed a higher monetary value on their searches than did ERIC subjects, indicated that they would make more frequent use of ddata bases in the future, and interacted more with the data base.

    Abstract
    Symbolic indexing and retrieval for effective searches of digitised images still seem to be frontier areas. Explains some criteria and concepts for searches of digitised images, refers to commercial software currently available for handling image data bases with alphanumeric indexing, and lists areas for research.

    Abstract
    A retrieval experiment was conducted to compare on-line searching using terms opposed to citations. This is the first study in which a single data base was used to retrieve two equivalent sets for each query, one using terms found in the bibliographic record to achieve higher recall, and the other using documents. Reports on the use of a second citation searching strategy. Overall, by using both types of search keys, the total recall is increased.
