....(mutable objects) whereas SILO does not. A common characteristic of the systems of both categories is that they give preeminence to logic, which is the basic reason of their drawbacks. There are, however, a few systems that use logic within an object based framework, such as ORIENT84 K [40] and HSRL [41] ORIENT84 K is a multi paradigm system, that is the object oriented part and the logic based part in an object are distinct and there is an interface between them, via special variables. This way does not offer a unified representation, whereas SILO does. HSRL is a limited ....

.... There has been significant discussion over the past several years about connections between research issues and practical techniques in the Object Based Concurrent Programming (OBCP) and the DAI communities [Bond and Gasser 88a, Ferber and Carle 92, Gasser et al. 87, Gasser and Huhns 89, Tokoro and Ishikawa 84, Yonezawa 90] Distributed AI has been concerned with representation, reasoning, and coordination in collections of computational agents. Object Oriented Concurrent Programming is based on the notion of active and autonomous objects which are computing concurrently and which interact by ....

.... technology for DAI systems, and a number of OBCP languages have been expressly designed, in whole or in part, to accommodate the needs of knowledge based systems and automated reasoning (e.g. ACTORS [Agha 86] ABCL 1 [Yonezawa 90] MERING IV [Ferber and Briot 88, Ferber and Carle 92] ORIENT84 K [Tokoro and Ishikawa 84] Still, few implementation platforms have been characterized in relation the social theory used in problem solving. Especially useful would be general (programming language and system level) relationships that link social DAI theories with appropriate implementation structures. On the whole, ....

....applications of esp to KR tasks which I am not aware of. 2.2 Orient84 K: Concurrency, OO and LP Orient84 K [11, 12] is a language and system developed by Mario Tokoro and Yutaka Ishikawa. It is the realization of a methodology which the authors call Distributed Knowledge Object Modeling (DKOM) [18] (but as mentioned before, I will not deal with the distributed aspects of Orient84 K here) Authors give a justification of DKOM based on a model of human behavior and knowledge processing which, although somewhat simplistic, seems convincing. They argue that the human behavior consists roughly ....

....the notion of the locus of execution or allocation of a processor to an object from object oriented computing. Thus, we can employ concurrent objects as a simpler unit for concurrent and distributed computing. Hewitt has been advocating this notion as the theory of Actor [Hewitt 73] Orient84 K [Tokoro 84] ConcurrentSmalltalk [Yokote 86] Yokote 87] also employ this notion. As a result, those languages have the following very important advantages: ffl Objects in the real world exist in parallel and execute in parallel. By using concurrent objects, it becomes very easy and natural to model ....
