    Abstract
    Describes metatheory as the analysis of the pressumptions of a field of knowledge or practice. Discusses the pressumptions as the basis of the practice of information science, in particular in relation to such concepts as information, knowledge (personal and public), message, message designation, information want and need, query, relevance and information search. Considers the nature of these pressumptions, and the conditions under which they may be replaced by others

    Abstract
    The paper aims to provide a non-technical introduction to the new procedures being used to extract knowledge from databases. The reasons for developing knowledge discovery methods are discussed - primarily, the current production of very large databases that may include many data relations not explicit in the database structure. The background in machine learning is indicated. The methods used are described for such techniques as classification (soting data into predefined classes), clustering (developing ab inition a data classification) and the detection of deviations from pre-established norms. Examples of the applications of these methods are given. The paper concludes with some brief thoughts about the potential use of knowledge discovery in the information field

    Abstract
    There is a huge amount of information and data stored in publicly available online databases that consist of large text files accessed by Boolean search techniques. It is widely held that less use is made of theses databases than could or should be the case, and that one reason for this is that potential users find it difficult to identify which databases to search, to use the various command languages of the hosts and to construct the Boolean search statements required. This reasoning has stimulated a considerable amount of exploration and development work on the construction of search interfaces, to aid the inexperienced user to gain effective access to these databases. The aim of our paper is to review aspects of the design of such interfaces; to indicate the requirements that must be met if maximum aid is to be offered to the inexperienced searcher; to spell out the knowledge that must be incorporated in an interface if such aid is to be given; to describe some of the solutions that have been implemented in experimental and operational interfaces; and to discuss some of the problems encountered. The paper closes with an extensive bibliography of references relevant to online search aids, going well beyond the items explicitly mentioned in the text. An index to software appears after the bibliography at the end of the paper
