the necessity and importance of teaching pragmatics has come to light by many researchers (e.g. rose & kasper, 2001). due to the consensus over the need to teach pragmatic competence, the main issue now centers on the question of how we should teach this competence in the most effective way. consistent with this line of research, the present study aimed to investigate the effectiveness of d...

Deductive program synthesis systems based on automated theorem proving o er the promise of \correct by construction" software. However, the diÆculty encountered in constructing usable deductive synthesis systems has pr evente d their widespr ead use. A mphion is a realworld, domain-independent programsynthesis system. It is specialized to speci c applications through the creation of an operatio...

The current study used the Space Fortress game (Donchin, 1989) to study the effects of training and instruction in acquisition of complex skills. The game requires flexible coordination of perceptual, cognitive and motor components in a dynamically changing environment. We examined whether effective instruction can be developed for such a task in the same way that instruction is developed for a...

A b s t r a c t. In this paper we shall study some extensions of the semilattice based deductive systems S (N) and S (N, 1), where N is the variety of bounded distributive lattices with a negation operator. We shall prove that S (N) and S (N, 1) are the deductive systems generated by the local consequence relation and the global consequence relation associated with ¬-frames, respectively. Using...

We report on a method of automated hypothesis generation, called f-resolution, which is derived from deductive resolution techniques. The method is inductive in character, in the sense that given input statement E, it generates hypotheses H, such that E is a deductive consequence of E. The method is extended by a generalized unification algorithm which introduces appropriate identity assumption...

In this paper we present R-DEVICE, a deductive rule language for reasoning about RDF metadata. R-DEVICE includes features such as normal and generalized path expressions, stratified negation, aggregate, grouping, and sorting, functions. The rule language supports a second-order syntax, where variables can range over classes and properties. Users can define views which are materialized and, opti...
