Recommender systems appeared in the early 90s to help users deal with cognitive overload brought by the internet. From there to now, such systems have assumed many other roles like help users to explore, improve decision making, or even entertain. The system needs to look to user characteristics to accomplish such new goals. These characteristics h...
Recommender systems have been constantly refined to improve the accuracy of rating prediction and ranking generation. However, when a recommender system is too accurate in predicting the users’ interests, negative impacts can arise. One of the most critical is the filter bubbles creation, a situation where a user receives less content diversity. In...
Filtering techniques like recommender systems are commonly employed to help people selecting items that best fit their conceptual needs. Although many benefits, recommender systems can put the user inside a filter-bubble given their high focus on similarity measures. This effect tends to limit user experiences, discovering new things, and so on. In...
The use of Recommendation Systems in virtually all online services nowadays makes people interact with them more and more, especially when considering the domain of intelligent cities.

It is an important topic in Active and Assisted Living (AAL) research and development to support elderly people suffering from memory impairment in their daily activities. A promising approach to such support is providing memory aids based on knowledge of how the person to be supported usually (i.e., in an unimpaired condition) copes with her/his d...
Abstract—Providing reminders to elderly people in their home
environment, while they perform their daily activities, is considered
as a user support activity, and thus a relevant topic in
Active and Assisted Living (AAL) research and development.
Determining such reminders implies decision-making, since the
actions’ flow (behavior) usually involves...
