Incremental Tractable Reasoning about Qualitative Temporal Constraints
In many applications of temporal reasoning we are in­ terested in reasoning incrementally In particular, given a CSP of temporal constrains and a new constraint, we want to maint...

Multiple Agents Moving Target Search
Traditional single-agent search algorithms usually make simplifying assumptions (single search agent, stationary target, complete knowledge of the state, and sufficient time). The...

Querying Distributed Data through Distributed Ontologies: A Simple but Scalable Approach
In this paper, we define a simple but scalable framework for peer-to-peer data sharing systems, in which the problem of answering queries over a network of semantically related p...

Recognizing Plan/Goal Abandonment
The ability to recognize when an agent abandons a plan is an open problem in the plan recognition literature and is a significant problem if these methods are to be applied in rea...

On the application of least-commitment and heuristic search in temporal planning
Graphplan planning graphs are structures widely used in modern planners. The exclusion relations calculated in the planning graph extension provide very useful information, especi...

Improving Word Sense Disambiguation in Lexical Chaining
Previous algorithms to compute lexical chains suffer either from a lack of accuracy in word sense disambiguation (WSD) or from computational inefficiency. In this paper, we presen...

Compiling Control Knowledge into Preconditions for Planning in the Situation Calculus
A promising technique used in some planning systems to improve their performance is the use of domain dependent search control knowledge. We present a procedure for compiling sear...
