Abstract
There is an increasing interest by cultural heritage organisations in developing hypermedia information systems to provide efficient ways to document, maintain, and search their data collections, and to open them to public access. However, search and retrieval of spatial data is known to suffer from many difficulties. Places normally have different versions of names, often change in size, boundaries, and centre co-ordinates. Furthermore, similarity between places is hard to calculate due to the wide range of characteristics associated with places and the complexity of inferring spatial relationships. This paper presents the research project OASIS, which attempts to improve spatial retrieval using a spatial hierarchy of places, enriched with thematic and geographical thesauri. OASIS applies a set of spatial measures to improve access by imprecisely matching places names.
