Agentcities needs ontologies that represent methods

This paper brings into evidence the need to have ontologies capable of representing methods, through a concrete real world example. DAML+OIL was the language chosen by Agentcities to model ontologies, but it has the shortage of being incapable of representing functions, actions or methods. Since DAML+OIL is an object-oriented approach, we propose the introduction of an extension to cope with methods. Methods are characterized by a list of input parameters and an optional output parameter. With the proposed extension, classes can be defined to have methods much in the same way as they are defined to have properties.
