....another. The same is true of properties. That is why there are many representation languages and mechanisms for exploiting them: semantic networks, conceptual graphs, and especially frame based systems (objects, frames) such as FRL [Roberts Goldstein 77] KRL [Bobrow Winograd 76] KL One, SRL [Wright Fox 83] Unit [Intellicorp 85] etc. The formalisms involved in these systems are not only incompatible with each other, which makes sharing the knowledge bases impossible, but they have characteristics such that it is difficult to extend them according to a given application. Even with a uniform ....

....involved in these systems are not only incompatible with each other, which makes sharing the knowledge bases impossible, but they have characteristics such that it is difficult to extend them according to a given application. Even with a uniform system like SRL (Schema Representation Language [Wright Fox 83] it is no easy matter to set up a distinction between conceptual knowledge and singular knowledge (instances) let us only recall the problems posed by the extension from SRL to CRL [Carnegie 85] concerning its object oriented programming layer. Finally, it is difficult to conceive a ....
