Requirements elicitation describes the activities needed to determine the requirements of a software system. It is essential to the success of a software development project. Requirements elicitation techniques are used by requirements engineers to discover the information needed to build systems that will satisfy the needs of stakeholders. This paper presents different types of software system...

We present in this paper a web-based tool developed to enable expert elicitation of the probabilities associated with a Bayesian Network. The motivation behind this tool is to enable assessment of probabilities from a distributed team of experts when face-to-face elicitation is not an option, for instance because of time and budget constraints. In addition to the ability to customize surveys, t...

Software requirements elicitation is a difficult process with many existing problems, and no single elicitation method solves all these problems. We introduce a new way of looking at the requirements elicitation process. Our model shows the requirements elicitation problem as a process of merging the users’ wants and the users’ needs into the same entity. In the context of our model, existing p...

The requirements elicitation phase of software development projects is characterised by the intensity and importance of communication activities. Requirements elicitation is a traditional exploratory phase in which context is analysed and an abstraction is performed as a consequence. However, exploratory processes are characterised by a deep interaction with environmental factors. In this paper...

Combinatorial auctions where agents can bid on bundles of items are desirable because they allow the agents to express complementarity and substitutability between the items. However, expressing one’s preferences can require bidding on all bundles. Selective incremental preference elicitation by the auctioneer was recently proposed to address this problem but the idea was not evaluated. In this...

Elicitator : an expert elicitation tool for regression in ecology. Abstract. Expert elicitation is the process of retrieving and quantifying expert knowledge in a particular domain. Such information is of particular value when the empirical data is expensive, limited or unreliable. This paper describes a new software tool, called Elicitator, which assists in quantifying expert knowledge in a fo...

The paper discusses the challenges of user emotion elicitation in socially intelligent services, based on the experimental design and results of the intelligent typing tutor. Human-machine communication (HMC) of the typing tutor is supported by the continuous real-time emotion elicitation of user’s expressed emotions and the emotional feedback of the service, through the graphically rendered em...
