A requirement analysis for a portfolio management in stock trading is presented. This provides a theoretical foundation for a stock trading system. The overall portfolio management tasks include eliciting user profiles, collecting information on the user’s initial portfolio position, monitoring the environment on behalf of the user, and making decision suggestions to meet the user’s investment ...

The electronic personal health record (PHR) has been championed as a mediator of patient-centered care, yet its usability and utility to patients, key predictors of success, have received little attention. Human-centered design (HCD) offers validated methods for studying systems effects on users and their cognitive tasks. In HCD, user-centered activities allow potential users to shape the desig...

A KADS based requirement analysis for the management of stock trading portfolios is presented. This provides a theoretical foundation for a stock trading system. This system is designed around portfolio management tasks that include eliciting user profiles, collecting information on the user’s portfolio position, monitoring the environment on behalf of the user, and making decision suggestions ...

Modeling automated user tasks based on agent-oriented approaches is a promising but challenging task. Personalized user agents have been investigated as a potential way of addressing this issue. Most of recent research work has focused on learning, eliciting and reasoning about user preferences and profiles. In this paper, our goal is to deal with the engineering of such systems, barely discuss...

Among the various tasks involved in building a Bayesian network for a real-life application, the task of eliciting all probabilities required is generally considered the most daunting. We propose to simplify this task by first acquiring qualitative features of the probability distribution to be represented; these features can subsequently be taken as constraints on the precise probabilities to ...

Building secure and usable systems means specifying systems for the people using it and the tasks they carry out, rather than vice-versa. User-Centered design approaches encourage an early focus on users and their contexts of use, but these need to be integrated with approaches for engineering secure systems. This paper describes how personas can augment a process for eliciting and specifying r...

[Context and Motivation] RE presents several challenges and risks stemming from the required collaboration and knowledge transfer between many different stakeholders, including analysts, developers and customers. [Objectives] This research aims to address these challenges by developing a gamification framework for enhancing motivation among professional software developers and analysts, to perf...

BACKGROUND We examined the effects of a foster care intervention on attention and emotion expression in socially deprived children in Romanian institutions. METHODS Institutionalized children were randomized to enter foster care or to remain under institutional care. Subsequently, the institutionalized and foster care groups, along with a community-based comparison group, were evaluated on em...

We propose a method to aggregate noisy ordinal labels collected from a crowd of workers or annotators. Eliciting ordinal labels is important in tasks such as judging web search quality and rating products. Our method is motivated by the observation that workers usually have difficulty distinguishing between two adjacent ordinal classes whereas distinguishing between two classes which are far aw...

An important way to make large training sets is to gather noisy labels from crowds of non experts. We propose a method to aggregate noisy labels collected from a crowd of workers or annotators. Eliciting labels is important in tasks such as judging web search quality and rating products. Our method assumes that labels are generated by a probability distribution over items and labels. We formula...
