This paper describes an architecture for building distributed information systems from existing information resources, based on software agent and distributed object technologies. An agent-based architecture is used, with messages exchanged via the FIPA agent communication language (ACL). Novel features of this system include the use of standards from the(More)
Agent-oriented software engineering is a promising new approach to software engineering that uses the notion of an agent as the primary entity of abstraction. The development of methodologies for agentoriented software engineering is an area that is currently receiving much attention, there have been several agent-oriented methodologies proposed recently(More)
The use of modelling abstractions to map from items in the real-world to objects in the computational domain is useful both for the effective implementation of abstract problem solutions and for the management of software complexity. This paper discusses the new approach of agent-oriented software engineering (AOSE), which uses the notion of an autonomous(More)
The use of explicit criteria to evaluate how well processes of care conform to accepted standards is a key method of quality assessment. Synthesizing four decades of literature, we devised an inexpensive, 6-step method of developing reliable, content-valid, explicit process criteria. This paper describes the method using a set of congestive heart failure(More)
This paper describes a multi-agent platform to be used for the integration of environmental information that may be distributed over a network. The system is designed to work as a collection of collaborating agents. Information sources are encapsulated as data source agents that accept messages in an agent communication language. Here we describe how(More)
This paper describes an architecture for building distributed information systems from existing information resources, based on distributed object and software agent technologies. This architecture is being developed as part of the New Zealand Distributed Information Systems (NZDIS) project. An agent-based architecture is used: information sources are(More)
THE UNIT to be described was designed to allow real-time video images from an ultrasound duplex scanner to be acquired on a microcomputer system for further image analysis, enhancement and subsequent animated display. The specific application envisaged was to collect arterial wall motion images during several cardiac cycles, process the images using(More)
