Vague spatial information such as “x is located at walking distance of y” is abundant on the web. In this contribution, we propose a framework to represent such spatial information, and show how new spatial relations may be deduced. Furthermore, we illustrate how this framework can be useful to increase the coverage of focused spatial information retrieval systems. Categories and Subject Descriptors I.2 [Artificial Intelligence]: Knowledge Representation Formalisms and Methods General Terms Fuzzy spatial reasoning
