Proposed here is an internal representation and mapping method for multimedia information in which retrieval is based on the impression documents desired to make. A user interface design for a system using this method is also proposed. The proposed internal representation and mapping method represents each desired document impression as an axis in a semantic space. Documents are represented as points in the space. Queries are represented as subspaces. The proposed user interface design employs a method of visual presentation of the semantic space. Pictorial examples are given to illustrate the range of impressions represented by the axes. The relations between the axes are represented by dispersion diagrams for the documents stored in the document base. With this method, the user can intuitively decide the appropriate subspace for his needs and can specify it directly. For evaluation purposes, a prototype system has been developed. An image retrieval experiment shows that the proposed internal representation and mapping method and the user interface design provide effective tools for information retrieval.
