We present schematic architecture for Internet based Knowledge Representation Interactive System which deals with mathematics story problem solving. The aim of this work is to develop an interactive system to accept mathematics story problem, process and give natural language answer. Our system uses propositional semantic network approach in natural language processing system with constraint so...

The design of believable emotional characters is the goal of the architecture described in this paper. The novelty of our approach relies on the distribution of the synthetic characters’ architecture in two complementary world models: semantic and physical. The characters emotional state is considered in the semantic world model, implemented as stand-alone Artificial Intelligence module, where ...

Interactive 3D graphics applications require significant arithmetic processing to meet the ever-inreasing desire for higher image complexity and higher resolution in displayed images. This paper describes a graphics processor architecture with a high degree of parallelism connected to a distributed frame buffer. The architecture can be configured with an arbitrary number of identical, high leve...

This paper deals with our work on interactive mathematical documents. These documents accomodate various sources, users, and mathematical services. Communication of mathematics between these entities is based on the OpenMath standard and Java technology. But, for the management of the communication, more protocols and tools are needed. We describe an architecture that serves as a framework for ...

Our feature configuration tool ST 2 Configurator integrates (1) a visual interactive representation of the feature model and (2) a formal reasoning engine that calculates consequences of the user’s actions and provides formal explanations. The tool’s software architecture is designed as a chain of components, which provide mappings between visual elements and their corresponding formal represen...

The paper describes the design and implementation of a security architecture for a HLA/RTI prototype developed at ONERA/CERT. The major security objective is to protect the intellectual property of firms participating to a distributed interactive simulation. We describe the techniques used to implement the security services: controlled subscription lists and secure associations. We report the i...

Interactive narratives have been used in a variety of applications, including video games, educational games, and training simulations. Maintaining engagement within such environments is an important problem, because it affects entertainment, motivation, and presence. Performance arts theorists have discussed and formalized many techniques that increase engagement and enhance dramatic content o...

This article presents the design and feasibility of a system that supports execution of High Level Architecture (HLA)–distributed interactive simulations in an unreliable Grid environment. The article presents an overall architecture of a system based on experience gained from previous designs. The most important operational components of the system are presented, and actual performance issues ...

Developing applications for interactive space is different from developing cross-platform applications for personal computing. Input, output, and architectural variations in each interactive space introduce big overhead in terms of cost and time for developing, deploying and maintaining applications for interactive spaces. Often, these applications become on-off experience tied to the deployed ...

Several knowledge management issues arise during the life-cycle of an interactive system. During the design phase software engineers need to acquire from users and domain experts knowledge about what they need and about the intended use of the interactive system. Subsequently, due to the phenomenon of user and system co-evolution, users modify their needs and/or their ways of using the system: ...
