In ambient intelligent systems, monitoring of a human could consist of more complex tasks than merely identifying whether a certain value of a sensor is above a certain threshold. Instead, such tasks may involve monitoring of complex dynamic interactions between human and environment. In order to enable such more complex types of monitoring, this paper presents a generic agent-based framework. ...

This paper describes research using an agent-based artificial agro-ecosystem model to simulate the interaction between pest movements and trap crop physical design. The result of simulation shows that artificial agro-ecosystem model has a broad application prospect in the field of agro-ecosystem management.

The acceptance of a knowledge-based system by the end user has been regarded as one of the major criteria for its success. The user interface design is one of the main reasons that hindered knowledge-based systems transition from prototype to everyday use. The success of knowledge-based systems therefore depends on the user interfaces as well as the efficiency of its knowledge encoding and reas...

Sometimes, descriptive and empirical agent-based models contain sub-models of variables whose change over time cannot be easily modelled. Due to a frequent lack of long-term data, especially on demographic change, often logical design principles are used for modeling such changes. The problem with these modeling principles is that many of them exist and the choice is a difficult one. We would l...

absTracT In order to stay competent and update in the fast changing landscape of technological advances, professionals nowadays are expected to continuously upgrade themselves of professional knowledge and expertise in their respective fields. Many professional organizations stipulate that their members should take part in a minimum number of hours or training units of continuous professional d...

It is increasingly important to design software for reuse so future changes can be implemented as easily and cheaply as possible. It is also beneficial to use existing resources where they are available. This paper describes an agricultural application for cumulative agrichemical residue tracking designed and implemented to use grid technologies to access external third-party databases and soft...

EXPECT provides an environment for developing knowledge-based systems that allows end-users to add new knowledge without needing to understand the details of system organization and implementation. The key to EXPECT's approach is that it understands the structure of the knowledge-based system being built: how it solves problems and what knowledge it needs to support problem-solving. EXPECT uses...

This paper describes methods for identifying appropriate software components for an application and for specifying the components’ operations rigorously. It uses the theory and methods of the design by contract approach for specification of the functionality. The actual implementations of a component’s operations are hidden from the clients and encapsulated within the component. A component com...

An increasingly relevant theme for knowledge-based systems is how to model and use a large and complex knowledge domain. On the one hand, this involves developing new ideas on a modular construction of a knowledge base and, on the other hand, an appropriate architecture of a knowledge-based system that takes account of such a modular knowledge base. In the HYPERCON project we conceptualize a co...
