    Abstract
    This paper describes a preliminary research project which applies Personal Construct Theory to individual user perceptions of photographs. The research has both theoretical and practical objectives, namely: to test the validity of Personal Construct Theory (Kelly's theory and corollaries) for subject content analysis of photographs, and to use Personal Construct Theory and repertory grids to enhance retrieval of photographs. The background to Personal Construct Theory and to the use of Repertory Grids is presented and there is an overview of applications of these techniques in library and information science and other disciplines. Research results Show a high level of consistency among the personal constructs which participants used to distinguish between photographs. While some problems associated with using Repertory Grids for subject content analysis are identified, the research concludes that they provide a useful method of collecting unbiased data about what users see in visual images and for comparing user perceptions with alternative retrieval vocabularies and methods. Incorporation of a participant's constructs in automatic classification systems for visual images remains a major challenge.

    Abstract
    Starts from the premise that meaning is not an intrinsic property of information items. Approaches to 'meaning' in diverse humanities disciplines, including philosophy, psychology, and the history of arts and music, are drawn on to enhance the understanding of meaning in the context of multimedia information retrieval on the Internet. The approaches described include philosophy of language and meaning, psychology of language including repertory grids and semantic differential, iconography and levels of meaning, and representation of music. A consistent theme in all these disciplines is the recognition that meaning is context dependent and may be analyzed at a variety of different levels, with nomenclature and number of levels varying across disciplines. Identifies the strengths and weaknesses of searching and retrieval on the Internet with particular emphasis on subject content and meaning. It shows the limitations of searching using the most basic level of meaning, while attempting to cater for a wide diversity of information resources and users. Recommends enhanced retrieval interfaces linked to the needs of specific user groups and the characteristics of specific media on the Internet
