We describe a tool, MatchMaps, that generates sameAs and partOf matches between spatial objects (such as shops, shopping centres, etc.) in crowd-sourced and authoritative geospatial datasets. MatchMaps uses reasoning in qualitative spatial logic, description logic and truth maintenance techniques, to produce a consistent set of matches. We report the results of an initial evaluation of MatchMap...

Cognitive models of orientation using aerial-view 2D diagrams such as maps could help us to predict where their contents and design help, or hinder, cognitive processes, resulting in more usable map designs for situations where orientation is a common problem. However, the complex realities of geographic space, and the large scale transformations required with maps, make it less easy to model e...

This paper describes a suite of tools developed at the University of Leeds which aim to make it easier for domain experts to be involved in the creation and use of ontologies. The paper summarises the main features of the tools and gives a short summary of our evaluations and experiences using the tools with domain experts. 1 Expressing Knowledge through a Controlled Natural Language At the cor...
