- Abstract
- In this paper we identify the need for a new theory of information. An information model is developed which distinguishes between data, as directly observable facts, information, as structured collections of data, and knowledge as methods of using information. The model is intended to support a wide range of information systems. In the paper we develop the use of the model for a semantic information retrieval system using the concept of semantic categories. The likely benefits of this area discussed, though as yet no detailed evaluation has been conducted.

- Abstract
- Free text and controlled vocabulary searching can no longer be viewed as antagonistic techniques in information retrieval since they both display advantages and weaknesses dependent on a fairly wide range of context, with the option to use both increasingly favoured. An attempt is made to present a list of features associated with the two techniques and to suggest a methodology to assist in deciding on the optimal retrieval technique for a particular purpose. The relevance of the techniques in expert systems and full text contexts is also discussed. Finally, recommendations for further research are suggested, concentrating on survey techniques in real-life retrieval situations

- Abstract
- The rapid pace of OPAC implementation in this country is providing a fruitful environment for research, with a wide range of projects currently being undertaken, including a number concerned with the application of advanced information retrieval techniques to OPAC systems. This article reviews the current situation and describes some of the more important research projects being undertaken, particularly those funded by the British Library Research and Development Department. A brief description of the British Library's own OPAC project is also provided. The article concludes with an examination of the value of OPAC research and a look at where further research effort might best be concentrated

- Abstract
- This article reports on a comparison of the postcoordinate retrieval effectiveness of two indexing languages: LCSH and PRECIS. The effect of augmenting each with title words was also studies. The database for the study was over 15.000 UK MARC records. Users returned 5.326 relevant judgements for citations retrieved for 61 SDI profiles, representing a wide variety of subjects. Results are reported in terms of precision and relative recall. Pure/applied sciences data and social science data were analyzed separately. Cochran's significance tests for ratios were used to interpret the findings. Recall emerged as the more important measure discriminating the behavior of the two languages. Addition of title words was found to improve recall of both indexing languages significantly. A direct relationship was observed between recall and exhaustivity. For the social sciences searches, recalls from PRECIS alone and from PRECIS with title words were significantly higher than those from LCSH alone and from LCSH with title words, respectively. Corresponding comparisons for the pure/applied sciences searches revealed no significant differences

- Abstract
- An essential part of information retrieval knowledge is the knowledge of data base contents and structures. Currently, the variety of data bases is so wide that it is difficult to know the contents and structure of a particular data base and how they differ from those of other data bases. Because of the lack of commonly acknowledged guidelines for data base descriptions, each on-line service designs and produces printed manuals, on-line help texts and other user documentation in its own manner. For the presentation of exact information and knowledge on a data base, common, structured principles for data base descriptions are needed. Requirements and some solutions for such description principles are presented.
