This paper uses a constraint set approach to linear programming problems with equality constraints whose coefficients and/or right-hand side values could be uncertain. We consider ...
In this paper, I will show how a controlled natural language can be used to describe knowledge for the Semantic Web and discuss the formal properties of this language. At the firs...
Constructive negation has been proved to be a valid alternative to negation as failure, especially when negation is required to have, in a sense, an `active' role. In this pa...
1 In [20], a new Hybrid Probabilistic Logic Programs framework is proposed, and a new semantics is developed to enable encoding and reasoning about real-world applications. In this...
We integrate a logic programming language into Meta-S, a flexible and extendable constraint solver cooperation system, by treating resolution as constraint solver. This new approac...
