    Abstract
    This article is about the mental coding processes involved in the flow of 'information' when the user is interacting with an 'enabling' information retrieval system. An 'enabling' IR system is designed to stimulate the user's grasping towards a higher understanding of the information need / problem / task that brought the user to the IR system. C. Shannon's (1949/1959) model of the flow of information and K.R. Popper's (1975) 3 worlds concept are used to diagram the flow of information between the user and system when the user receives a stimulating massage, with particluar emphasis on the decoding and encoding operations involved as the user processes the message. The key difference between the model of information flow proposed here and the linear transmission, receiver-oriented model now in use is that we assume that users of a truly interactive, 'enabling' IR system are primarily message senders, not passive receivers of the message, because they must create a new message back to the system, absed on a reconceptualization of their information need, while they are 'online' interacting with the system

    Abstract
    In order to test how associated verbal and spatial stimuli are processed in memory, undergraduates studied a reference map as either an intact unit or as a series of individual features, and read a text containing facts related to map features. In Addition, the map was presented either before or after reading the text. Seeing the intact map prior to the text led to better recall of both map information and facts from the text. These results support a dual coding modell, where stimuli such as maps possess a retrieval advantage because they allow simultaneous representation in working memory. This advantage occurs because information from the map can be used to cue retrieval of associated verbal facts, without exceeding the processing constraints of the memorial system

    Abstract
    Hypertext uses a browsing rather than a searching strategy. Hypertext systems have found applications in a number of areas. They give users choice of information but this can prove a drawback. Examnines the effectiveness of hypertext as a way of retrieving information and reviews conventional information retrieval techniques. Considers previous attempts at combining information retrieval and hypertext and outlines a prototype systems developed to generate guided tours for users to direct them through hypertext to information they have requested. Discusses how adding this kind of itelligent guidance to a hypertext system would affect its usability as an information system

    Abstract
    Cognitive research into information science started at the International Workshop on the Cognitive viewpoint, Ghent, Belgium, 1977, where it was made clear that the task of research is to improve information flow, specifically through creating models of users' knowledge compatible with the conceptual frameworks used by information retrieval systems. Divides users' knowledge into knowledge of the world, of the information retrieval system, of the task and of the domain. Cognitivism as a research direction in information science explains how the cognitive processes and objects might influence information retrieval and representation

    Abstract
    The existing tools of relevance, recall and precision have their place in the evaluation of information retrieval systems, but do not tell the whole story. They cannot, for example, make allowance for the enquirer already knowing of the existence of a document or the subsequent availability of items. Utility theory goes part way towards meeting the need by assessing the likely usefulness of documents. Arguing that information is not information until it is used, the paper suggests an additional approach to information system evaluation - the 'use-value' of information

    Abstract
    Information is and always has been an elusive concept; nevertheless many philosophers, mathematicians, logicians and computer scientists have felt that it is fundamental. Many attempts have been made to come up with some sensible and intuitively acceptable definition of information; up to now, none of these have succeeded. This work is based on the approach followed by Dretske, Barwise, and Devlin, who claimed that the notion of information starts from the position that given an ontology of objects individuated by a cognitive agent, it makes sense to speak of the information an object (e.g., a text, an image, a video) contains about another object (e.g. the query). This phenomenon is captured by the flow of information between objects. Its exploitation is the task of an information retrieval system. These authors proposes a theory of information that provides an analysis of the concept of information (any type, from any media) and the manner in which intelligent organisms (referring to as cognitive agents) handle and respond to the information picked up from their environment. They defined the nature of information flow and the mechanisms that give rise to such a flow. The theory, which is based on Situation Theory, is expressed with a calculus defined on channels. The calculus was defined so that it satisfies properties that are attributes to information and its flows. This paper demonstrates the connection between this calculus and information retrieval, and porposes a model of an information retrieval system based on this calculus
