Situation identification is a complex task that is usually employed in order to sustain the work of Decision Support Systems in several and heterogeneous application scenarios like, for instance, Emergency Management, Safety and Security. Typically, situation awareness systems gather and process raw sensor data by means of different techniques. In this context, it is fundamental to exploit qualitative...
Handling the continuity of learning experience across different activities and contexts is a key challenge for seamless learning. Current context and activity recognition techniques work well in fixed environments where sensors deployment and data are known but are not adaptable to dynamic and changing situations when, for instance, a learner moves from dense to rare sensor environments. Moreover,...
In order to enable and support lifelong learning, learners need to be aware of their learning processes. This work proposes a framework for supporting Self-regulation in Seamless Learning scenarios. The framework is based on the Endsley's Model for Situation Awareness. Moreover, the framework is contextualised to a specific class of learning scenarios in order to better explain its potentiality. In...
The main barrier to a mainstream adoption of Semantic Web and Linked Data is the difficulty for users to search and retrieve the required information in this huge network of data. This work proposes a novel approach for Ubiquitous Browsing and Searching Linked Data. The proposed approach lays on a conceptual communication model, namely Interactive Alignment, for disambiguating both users' intentions...
Thanks to the phenomenal proliferation of the electronic commerce, the number of Internet shops increases more and more each year. This increasing forces strong competition on the market by leading to low prices for customers, but, at the same time, it represents a problem for customers since it makes difficult to manually compare all the product offers and decide a shopping plan. This scenario is...
The evolution of microchips and embedded technologies and those related to the mobile world has led to the growth and proliferation of devices and systems for electronic payment used by end users to buy products or services. Over the last few years there has been a tendency to use these devices and systems to provide users a way to benefit of services that are accessories to the payment (e.g. Value...
In recent years, merchants have increased their interest in marketing strategies based on loyalty programs. Coalition loyalty is one of the most profitable among the aforementioned strategies. This work proposes a co-operation model based on the principles of Collective Knowledge Systems and on Semantic Technologies to support the generation and management of dynamic coalitions of merchants. The main...
