of representation and retrieval of visualmedia were confined to specialized image databases (geographical, medical, pilot experimentsin computerized slide libraries), in the professional applications of the audiovisualindustries (production, broadcasting and archives), and in computerized training or education

We propose a model of the spatial visual processes underlying the identification and representation of the shape of primitive spatial regions. We propose that a region's boundaries are sensed at multiple scales by boundariness detectors that give graded responses, that stimulated boundariness

interesting properties, among others the capacity to generate a realistic research agenda. We postulate here that two core relations (representation and conformance) are associated to this principle, as inheritance and instantiation were associated to the object unification principle in the class

). lpg is an incremental, any time system pro-ducing multi-criteria quality plans. The core of the system is based on a stochastic local search method and on a graph-based representation called “Temporal Action Graphs ” (TA-graphs). This paper focuses on temporal planning, introducing TA

In this paper, I compare and contrast two formal results on the computational complexity of core membership determination in two compact representations of coalitional games. Conitzer and Sandholm [1] proposed the multi-issue representations of coalitional games. This representation attempts

simulator within frictional regime with only a few small additions to account for inter-grain and boundary friction, yet with visually acceptable result. We also propose an alternative method for simulating fluids. Our core representation is a cloud of particles, which allows for accurate and flexible

Information Integration is one of the core problems in distributed databases, cooperative information systems, and data warehousing, which are key areas in the software development industry. Two critical factors for the design and maintenance of applications requiring Information Integration

of this problem, scopal ambiguities in natural language expressions, is discussed in section 2. The core of the paper presents Hole Semantics. This is a general proposal for a framework, in principle suitable for any logic, where underspecified representations play a central role. There is a clear separation

-level in the form of instantiated modeling primitives within a so called Probabilistic Ontology Model (POM), we remain independent of a concrete target language while being able to translate the instantiated primitives into any (reasonably expressive) knowledge representation formalism. Second, user interaction
