In this paper we focus on the problem of how infinite belief hierarchies can be represented and reasoned with in a computationally tractable way. When modeling nested beliefs one ...
We present a query language, called the Datalog++ , for deductive object-oriented databases. While a direct semantics for inheritance with overriding and encapsulation is desirabl...
Formal AI systems traditionally represent knowledge using logical formulas. We will show, however, that for certain kinds of information, a modelbased representation is more compa...
Abstract. Ontologies are pervading many areas of knowledge representation and management. To date, most research efforts have been spent on the development of sufficiently express...
We design a representation based on the situation calculus to facilitate development, maintenance and elaboration of very large taxonomies of actions. This representation leads to...
