The need to integrate automatic communication systems in daily applications and technology progress has encouraged speech synthesis sector development. Many variety of voice systems synthesis exist but diphones concatenation method appears to be efficient to contribute to speech synthesis of many languages. The first task in any development of speech synthesis system is to prepare the data base used...
The growing incidence of web 2.0 challenges the traditional offline retailers to create a new method of shopping and new usage of consuming goods and services through a virtual shopping space over electronic store. A new contextual framework of customer and retailers relationship emerges through the aggregation and collaborative-shared opinion on the personal preferences about goods in the Web. While...
Nowadays, Internet communication and especially informal Internet communication such as social networks, blogs, etc. is directing politic, economic, financial and social environments all over the world. Consequently, Internet monitoring is taking more and more scale particularly in Tunisia suffering from unsteadiness since the politic revolution in 2011. In a Tunisian context, Internet communication...
Citizens can be considered as an important source of knowledge for innovating in open contexts, collaborating with initiatives for developing solutions to urban issues, in order to get improvements addressed to a collective well-being.
The paper discusses the challenges and chances for the use of Earth Observation (EO) as a supportive information source in the development of Low Carbon Action Plans. The process of Low Carbon Action Planning is described and analyzed with regard to information gaps that can be bridged using the support of EO derived information products. In addition, the potentials for utilization of urban remote...
In this paper we analyze operational energy data of the cooling, ventilation and heating systems of the professional soccer stadium Commerzbank Arena in Frankfurt, Germany. We analyze data collected over a six month period in 2014 statistically and show that depending on the stadium's operational context consumption patterns vary largely among the different systems resulting in very different behaviors...
Design Science research is a mainstream Information systems discipline, yet Living Lab literature seems not to leverage its insights. The paper describes how Living Labs can be conducted as Design Science Research (DSR) by adapting the Action Design Research method. The resulting method is named LL-ADR. A case is presented to indicate how LL-ADR can be applied and findings for both Living Labs and...
This paper presents a model for metacognitive learning evaluation in a community of inquiry and discusses how it may be used to incentivize effective learning in online graduate courses. We identify patterns of behavior and peer-learner interactions that indicate social engagement in community model building, based on an extensive, qualitative analysis of online course discussions and student interaction...
A proposed approach supports the continual construction and evolution of model-based Internetware artifacts by a collective of Internet-connected stakeholders. The key mechanism is incremental graph superimposition (IGS), a refinement of stigmergy, the process that produces collective intelligence in social insects. Employing IGS, a collective of individuals collaboratively and continually construct...
Over recent years, more and more companies have come to recognise the utility of storytelling in the workplace. Stories are thought to be an effective means of sharing information and can fulfil a range of knowledge management functions. Furthermore, storytelling can contribute to social bonds between co-workers because stories allow the audience to create impressions about the attitudes and beliefs...
Over several decades, a variety of studies have analysed analogical thinking as a cognitive mechanism, in which the individual transfers information from similar situations or problems and uses it to solve problems. However, less research is given that focuses on the use of predefined analogies as external stimuli for the ideation process. As a result, there has been very little information available...
Much research exists regarding (computer-supported) idea generation, yet little is known about how teams can be facilitated to efficiently converge on a set of ideas. Convergence is a critical activity in collaborative problem-solving and decision-making as teams need to focus their cognitive resources on the most promising ideas resulting from a brainstorming activity. This paper investigates the...
The paper develops a two-step approach to identify factors driving the propensity of product firms to enter services, and the mode of entry. We posit that the level of vertical integration, market size and the position of the firm's product offerings in the phase of the product development lifecycle influence the propensity of entry into services. The mode of entry is a choice between firms exploiting...
Improving the egocentric network-based user's profile building process by taking into account the dynamic characteristics of social networks can be relevant in many applications. To achieve this aim, we propose to apply a time-aware method into an existing egocentric-based user profiling process, based on previous contributions of our team. The aim of this strategy is to weight user's interests according...
As mobile devices increasingly incorporate a range of sensors, there is significant potential to apply opportunistic sensing techniques to allow collections of these devices to provide context information to applications. Focussing on a use case involving the use of mobile devices to sense and localize increasing levels of gases in a work environment, we show that the use of application-specific state...
Crowdsourcing is a new distributed computing paradigm that leverages the wisdom of crowd and the voluntary human effort to solve problems or collect data. In this context, trustworthiness of user contributions is of crucial importance to the viability of crowdsourcing. Prior mechanisms either do not consider the trustworthiness or quality of contributions or have to assess it only after workers' submission...
Resource management is challenged to apply the resources currently available and those that are to become available in the future to achieve goals efficiently. Normally, when resources are scarce, this is not an easy task, especially when the environments are real- time, partially observable, dynamic and uncertain. Despite being very common in the real world as well as in digital games, in particular...
Mobile apps running on smartphones have not only become a popular means for providing mobile services. Due to their relatively easy and cheap implementation, they have also developed into scientific tools for studying mobile human-computer interaction (HCI) in realistic usage contexts, providing qualitative and quantitative data about usage patterns and user preferences with a high degree of ecological...
Scenario planning provides a way for system thinking of driving forces and their interactions (or cause/effect relationships) and thus helping for construction of the knowledge structure of future environment and their strategic implication for DRR management and innovations. Also, scenario planning helps in discovering and widening the thinking of future needs in DRR and possible application contexts...
The selection of resources within a university campus is not an easy task, due the multitude of physical and virtual resources available. By this fact, a person can easily select a set of resources that cannot attend their needs and interests in the best way. Such multitude of resources can leads to the problem of the person cognitive overload, which happens during the resources selection. This paper...
