Virtual and robotic agents are becoming increasingly prominent, taking on a variety of everyday life roles (i.e., assistants, tutors, coaches, companions). Displaying social and affective behaviour is a necessary requirement when agents need to interact and collaborate with humans. Nevertheless, current agent prototypes lack important skills, such as recognising human emotions,…

The thesis examines political discourse quality online and proposes a methodology for analyzing online conversations in an automated way. The study builds on Habermas' work by examining the quality of the public sphere in a digital age. Primarily, it examines the portion of the public sphere which deals with political discussions on online platforms. The proposed technique,…

In this thesis, we propose a model for semantic digital libraries with a geospatial context and a definition of coverage as key concept. We present the document and spatial resource model. We define the annotation model and more particularly the geographic coverage that detail and define the location of each resource taking into account its type. Finally, we present the query model…

Smart mobile services and applications use users' context. However, we never investigate how users perceive this context and how to leverage this perception for even smarter services. We represent the perception of the context of users as their intimacy, their familiarity with their current place, the number, and kind of people around them. The adjective ‘intimate'…

The thesis proposes an interdisciplinary framework for service research in information systems that goes beyond the technological concerns and integrates the business concerns about service processes and models and the user's concerns about service usage and value. Based on this framework, the thesis analyzes further the concept of service value and suggests the value…

Nowadays BYOD and mobile work are a reality even if they challenge traditional security perimeters and risk management that mainly focus on the threats that these mobile opportunities create. They do not consider their potential benefits, e.g., if a user cannot work when being paid then the productivity is lower. It is the reason that in this paper we introduce a new risk management…

Wireless networks today are partially being formed by nodes (e.g. Internet access points, smartphones, femtocells) that are owned and carried by humans. In such scenarios where several strangers are expected to interact for the sake of robust data transmission, trust and cooperation incentives are of vital importance as these establish a way for the nodes involved in the system to…

When scientists are looking for information in document collections, they generally have a precise objective in mind. They try to answer specific needs such as finding the definition of a concept, checking whether an idea has already been tested, or comparing the scientific conclusions of several documents. To build better information system model it is important to understand the…

The main challenge for steering IS evolution is to cope with the uncertainty inherent to any IS change, while taking into consideration its complexity due to the entanglement of its multiple dimensions: regulation, information, activity and technology. We observe that i) steering IS evolution requires understanding its IS domain, ii) its impacts are difficult to predict and iii) the…
