A distributed system is described in which resource utilisation decisions depend upon the categorisation of resource descriptions stored in the distributed system. In the principal embodiment, the resource descriptions are web service descriptions which are augmented with tags (i.e. descriptive words or phrases) entered by users and/or by web service administrators. A service taxonomy is constructed on the basis of the tags, and is subsequently used in suggesting tags to the user which the user might want to ascribe to the service in question. This leads to a more coherent and focussed set of tags in the system, which in turns results in better resource utilisation decisions and hence a more efficient use of the resources of the distributed system.
