This paper describes a Recommender System that implements a Multiagent System for making personalised context and intention-aware recommendations of Points of Interest (POIs). A twoparted agent architecture was used, with an agent responsible for gathering POIs from a location-based service, and a set of Personal Assistant Agents (PAAs) collecting information about the context and intentions of its respective user. In each PAA were embedded four Machine Learning algorithms, with the purpose of ascertaining how wellsuited these classifiers are for filtering irrelevant POIs, in a completely automatic fashion. Supervised, incremental learning occurs when the feedback on the true relevance of each recommendation is given by the user to his PAA. To evaluate the recommendations' accuracy, we performed an experiment considering three types of users, using different contexts and intentions. As a result, all the PAA had high accuracy, revealing in specific situations F1 scores higher than 87%.
In this paper we report on a game design exercise that focus on the sensoriality and sensemaking participant dimensions for conceiving and evaluating gameplay experience, by framing design intentions, artifact characteristics and user participation. Through this exercise we were able to build understandings of user participation in the soundscape constituting the gameplay scenario. By employing a goal-question-metric approach we demonstrated the viability of using the participation-centric gameplay model dimensions as a basis for the synthesis of gameplay participation indicators and metrics, and their analysis in the context of interactions with a game as soundscape.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
