The use of intelligent agents is on the rise, fueled by the unprecedented growth in the Internet and web based applications. Consequently, agent-oriented software is becoming large and complex. To support a systematic development of such software, an agent-oriented software development methodology is necessary. This paper focuses on the modeling phase of agent-oriented software life cycle and, ...

Service Oriented Programming which combines Distributed Object Compunting, Component Based and webbased concepts has recently emerged as a promising approach to develop dynamic and heterogeneous service provision environments. Such systems are referenced in literature as Service Oriented Architectures. Classic strategies to address dependability in Distributed Object Computing middlewares may n...

The information universe provides the highest common framework found in all organizational information systems combining data models, business rules, organizational roles, and the members of an organization. Th,e conceptual model of development shows that a vertical dimension to design and implementation leads to an extensible and object oriented domain model. Extensibility and the object orien...

Essential modeling extracts essential user requirements [4, 6, 11. Here, we propose using essential model to identify, organize, and present essential requirements of users for object-oriented projects. Comparcd with an analysis model, an essential model does not decompose the problem of a project or suggest any solution for the problem. An essential model crystallizes externally visible requir...

A common tool for improving the performance quality of natural language processing systems is the use of contextual information for disambiguation. Here I describe the use of a finite state machine (FSM) to disambiguate speech acts in a machine translation system. The FSM has two layers that model, respectively, the global and local structures found in naturally-occurring conversations. The FSM...

This position paper takes a bottom-up approach that analyzes the suitability of UML for modeling aspect-oriented software, and compares it with the UML support for modeling object-oriented software. We first introduce the basic concepts of AspectJ, a state-of-the-art aspect-oriented programming language, and then take a naïve approach using standard UML, as it is, for modeling these concepts. A...

Crosscutting concerns are pervasive in embedded software, because of the various constraints imposed by the environment and the stringent QOS requirements on the system. This paper presents a framework for modularizing crosscutting concerns in embedded and distributed software, and automating their composition at the modeling level, for simulation and validation purposes. The proposed approach ...

This work introduces Expectation-oriented Modeling (EOM) as a conceptual and formal framework for the modeling and in uencing of blackor gray-box agents and agent interaction from the viewpoint of modelers like arti cial agents and application designers. EOM is unique in that autonomous agent behavior is not restricted in advance, but only if it turns out to be necessary at runtime, and does so...
