    Abstract
    Describes a research project, in which similarity measures have been extended to include imprecise matching over different dimensions of structured classification schemes (subject, soace, time). The semantic similarity of information units forms the basis for the automatic construction of links and is integrated into hypermedia navigation. Outlines a semantic hypermedia architecture, and a prototype museum social history application. Presents illustrative navigation scenarios which make use of a navigation via similarity tool. The temporal mesaures of semantic closeness underpin the similarity tool. The temporal measures takes account of periods as well as time points. The most general measure is based on a traversal of a semantic net, taking into account relationship type and level of specialisation. It is based on a notion of closeness rather than absolute distance, and returns a seit of semantically close terms. Discusses a methods of calculating semantic similarity between sets of index terms, based on the maximal closeness values achieved by each term

    Abstract
    Describes an integrated approach to similarity coefficients for information spaces with multiple dimensions of different types of index term. Categorises applications of similarity coefficients underlying different navigation tools in hypermedia by type of term. Describes an implementation of a unified similarity coefficient based on work in numerical taxonomy, with illustrative scenarios from an experimental navigation via similarity tool for a prototype social history museum hypermedia system. The underlying architecture is based on a semantic approach, where semantic relationships can exist between index terms. This allows imprecise matching when comparing for similarity, with distance measures yielding a degree of match. A ranked list of matching items over several weighted dimensions is returned by the similarity navigation tool. The approach has the potential of allowing different access methods to multimedia data to be combined
