    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
    Reports from the IIS Text Retrieval Conference, Oct.92. Although considerable progress has been made in the last 3 years with hypertext and Windows type GUIs, text retrieval performance has made little progress. Considers how linguistic factors influence performance, the development of indexing language tests, the worth of the thesaurus and controlled vocabularies and menu driven versus intuitive interfaces. Discusses hypertext and multimedia including the Sony Electronic book
