The shift of emphasis away from written to oral skills has stimulated an incipient concern in second language research to investigate ways of helping second and foreign language learners achieve higher degrees of oral proficiency. Priority solely taken over accuracy, complexity, or fluency of speech might be justifiable with regard to the context in which learning takes place.  Accuracy and com...

Recent research in planning is more and more focusing on planning systems working in \real world" domains. These systems need to act in, sense and represent the real world. Furthermore, no action, even if apparently simple, is guaranteed to succeed and, therefore, no planning can be \sound" (with respect to the real world) without taking into account possible failures. This is mainly due to the...

Agents and planning systems represent two modern intelligent techniques. Although these two techniques can be very successfully combined, not much work has been done on their integration. One of the main reasons for this is the fact that these two kinds of systems evolved in an independent manner. Planning systems started their evolution in the early 1960’s and 70’s when systems GPS (General Pr...

In recent years research in the planning community has moved increasingly towards application of planners to realistic problems involving both time and many types of resources. For example, interest in planning demonstrated by the space research community has inspired work in observation scheduling, planetary rover exploration and spacecraft control domains. Other temporal and resource-intensiv...

KA Tool embodies work aimed at allowing domain experts to generate a domain model for an AI planning system, carried out as part of a larger project to build an integrated set of tools for supporting AI planning. The paper outlines the overall methodology and describes how KA Tool supports it. A Domain model is generated in which can be represented by cluster of constraints shaping an Ontology ...
