Research paper thumbnail of Teaching Of A Case Study For Expert SystemsConstruction

Usually, the students have to face with real problems without enough preparation. They solve small examples in the classroom and then, they develop a real project. A smooth transition between examples and project is necessary. This paper discusses a Case Study that serves as a transition between what the students learn in classroom and the real world problems. We take into account other educational experiences in KBS and a total quality model for expert systems.

Usability has become a critical quality factor in software systems, and it requires the adoption of a human-centered approach to software development. The inclusion of humans and their social context into the issues to consider throughout development deeply influences software development at large. Waterfall approaches are not feasible, since they are based on eliminating uncertainty from software development. On the contrary, the uncertainty of dealing with human beings, and their social or work context, makes necessary the introduction of uncertainty-based approaches into software development. HCI (Human-Computer Interaction) has a long tradition of dealing with such uncertainty during development, but most current software development practices in industry are not rooted in a human-centered approach. This paper revises the current roots of software development practices, illustrating how their limitations in dealing with uncertainty may be tackled with the adoption of w...

There is neither an objective criterion to measure the quality of a software design nor a general strategy to manage complexity and uncertainty. Ambiguity, as a specific kind of uncertainty, is a powerful tool to face uncertainties in the environment as well as a descriptive complexity reduction mechanism. Ambiguity is present at every level and stage of the software process, which has never been acknowledged by the software engineering community. We show that many of the sophistications in software design, from the use of variables in assembly language to the most recent patterns in object-oriented design, are in fact uses of ambiguous relationships among software elements. Ambiguity can help to establish the basis of a software design theory.

At the beginning, the software universe only appreciates the beneficial side of uncertainty, although it took advantage of it. Software is practically useless without uncertainty. Nowadays, uncertainty is more used as a tool but this is not recognized and it causes several problems. In that sense, this work
