REACTOR is an expert system under development at EG&G Idaho, Inc., that will assist operators in the diagnosis and treatment of nuclear reactor accidents. This paper covers the background of the nuclear industry and why expert system technology may prove valuable in the reactor control room. Some of the basic features of the REACTOR system are discussed, and future plans for validation and eval...

Very early, there was an insight that explanation was crucial for system acceptance. I remember that in Buchannan’s and Shortliffe’s early work on medical consultation systems, the ability to create explanations was a number one requirement. Initially, it seemed that simple explanation mechanisms might be sufficient, and tracing the rules used by an expert system is straightforward. Fairly soon...

Software forensic experts are called upon not only to perform authorship analysis and software copyright infringement forensics but also to perform software quality forensics. Because the prime evidence in such cases also are digital (in the form of software, databases etc.), the judiciary too often engages software forensic practitioners as expert witnesses to arrive at a considered judgment. ...

Knowing the faults early during software development helps software manager to optimally allocate resources and achieve more reliable software within the time and cost constraints. A model is proposed in this paper to predict total number of faults before testing using a fuzzy expert system. The proposed model predicts number of faults at the end of each software development phase using reliabi...

Expert-based estimation is the most common and preferred method to estimate the effort for software development project because it is fast, less expensive and reasonably accuracy. Expert software developers use his intuition and experience during effort estimation task. Estimation by analogy of features is also used to compare the new feature to similar in past development. This paper extends r...

There are serious problems with uncertainty referred to various aspects during evolutional development of an innovative software product. An open list of uncertain items in an expert system development is presented. In AI area some formal approaches to uncertainties are applied to build an expert system for medical diagnostics. Following the general idea applied in medicine, an informal approac...

This study attempted to investigate writing problems and the relationship between expert-assessment and self-assessment of writing problems. Participants were thirty four non-English faculty members of Tehran and Guilan universities. The instruments were writing an essay on the topic "What teaching strategies do you use in your classes?" in twenty five lines and filling the questionnaire of wri...

This paper presents Baseline Oriented Modeling– Lazy (BOM–Lazy): an approach to develop applications in a domain, Expert Systems, by means of Software Product Lines and model transformations techniques. A domain analysis has been done on the variability of Expert Systems that perform diagnostic tasks in order to determine the general and individual features, (i.e. common and variants features) ...
