Knowledge plays an important role to the success of any organization. Software development organizations are highly knowledge-intensive organizations especially in their requir ement elicitation process (REP). There are several problems regarding communicating and u sing the knowledge in R EP such as misunderstanding, being out of scope , conflicting information and changes of requirements. All...

Requirements elicitation is the process of seeking, uncovering, acquiring, and elaborating requirements for computer based systems. It is generally understood that requirements are elicited rather than just captured or collected. This implies there are discovery, emergence, and development elements to the elicitation process. Requirements elicitation is a complex process involving many activiti...

ÐIn this paper, we present and discuss our experience in the task of probability elicitation from experts for the purpose of belief network construction. In our study, we applied four techniques. Three of these techniques are available from the literature, whereas the fourth one is a technique that we developed by adapting a method for the assessment of preferences to the task of probability el...

A hybrid system for automatic knowledge acquisition for expert systems is presented. The system integrates artificial intelligence and cognitive science methods to construct knowledge bases employing different knowledge representation formalisms. For the elicitation of human declarative knowledge, the tool contains automated interview methods. The acquisition of human procedural knowledge is ac...

One of the key advantages of the Bayesian paradigm is the ability to incorporate past experiences and expert opinion into statistical analyses. However, the principled, precise distillation of expert opinion into a probability distribution, a task known as prior elicitation, is challenging and involves considerations from psychology, computational science, software engineering, and other relate...

Contact hypersensitivity (CHS) is a form of delayed-type hypersensitivity triggered by the response to reactive haptens (sensitization) and subsequent challenge (elicitation). Here, we show that ASK1 promotes CHS and that suppression of ASK1 during the elicitation phase is sufficient to attenuate CHS. ASK1 knockout (KO) mice exhibited impaired 2,4-dinitrofluorobenzene (DNFB)-induced CHS. The su...

Requirements elicitation consists in collecting information about the requirements and the environment of a systemto-be. It usually involves business analysts who are eliciting information, and stakeholders who are providing information. This paper investigates how the commitment of stakeholders to a RE project influences the results of elicitation. We suggest a way to measure the commitment of...
