Older adults with early‐stage dementia (ED) can experience confusion or lack clarity when performing routine activities of daily living (ADLs). These circumstances predispose the older adult to safety‐critical and often risky situations. A safety‐critical risky situation is one that constitutes a hazard. To support independent living, a sensor‐laden smart environment can be employed to mitigate such...
In this paper, I first review the seminal work by Thomas Kuhn — The Structure of Scientific Revolutions — and elaborate my view on paradigm shifts in software engineering research and practice as it turns 50 years old in 2018. I then examine major undertakings of the computing profession since early days of modern computing, especially those done by the software engineering community as a whole. I...
Human factors have been increasingly recognized as one of the major driving forces of requirement changes. We believe that the requirements elicitation (RE) process should largely embrace human-centered perspectives, and this paper focuses on changing human intentions and desires over time. To support software evolution due to requirement changes, Situ framework has been proposed to model and detect...
In this paper we present a new human-centered requirements elicitation methodology that effectively considers end-user's desire, behavioral and environmental contexts. We follow a methodology that uses a computationally rich definition of situation as a 3-tuple where d denotes human desire, A denotes the action vector, and E denotes the environment context vector. The proposed method of human-centered...
User's new requirements on a system are critical factors for driving software service evolution. New requirements usually arise when users are not satisfied with the existing system as often reflected in users' divergent behaviors that can be detected through comparison with the known behavior patterns. In this paper, we propose a methodology that applies Conditional Random Fields (CRF) as the mathematical...
