Most of today’s commercial companies rely heavily on social media and community management tools to interact with their clients and analyze their online behaviors. Nonetheless, these tools still lack evolved data mining and visualization features to tailor the analysis in order to support useful marketing decisions. We present an original methodolo...

In today’s world, making a good travel plan is not an easy task for most people. However, the situation is even more complicated for people with disabilities. For them, even simple trips, such as travelling to visit a museum or an exposition, have become extremely difficult. A wide variety of travel planning needs to be made days or months in advan...

Building government services with an interconnected administration approach is a worldwide trend aimed to solve the complexity of government-related processes. The connection between people and services relies on technical tools that could benefit from improvements at the data level, by more easily sharing and having a better interlinking of data f...

Switzerland is one of the most desirable European destinations for Chinese tourists, a better understanding of Chinese tourists is essential for successful business practices. In China, the largest and leading social media platform – Sina Weibo, has more than 600 million users. Weibo’s great market penetration suggests that tourism operators and ma...

How social media could be used to interpret the satisfaction of clients visiting a destination based on real use cases? 2.078 Billion active social media accounts (29% of the total population) +12% active social media account compared to 2014 (+222 Million) 16 min/hour is the time spent on social networks in the USA 23% of Facebook users login at l...

Switzerland is one of the most desirable European destinations for Chinese tourists; therefore, a better understanding of Chinese tourists is essential for successful business practices. In China, the largest and leading social media platform—Sina Weibo, a hybrid of Twitter and Facebook—has more than 600 million users. Weibo’s great market penetrat...

This paper presents solutions that leverage Semantic Web Technologies (SWT) to allow pragmatic traceability in supply-chains, especially for the textile industry. Objectives are the identification of the supply-chain, order management, tracking and problem reporting (such as dangerous substance detection). It is intended to be a generic platform su...

Managing energy data from multiple distributed and heterogeneous sources is an important issue worldwide. This study focused on using semantic web technologies in an energy data management system. Specifically, we provided a federated approach - a mediator server - that allows users to access to multiple heterogeneous data sources, including four t...

The integration of data from multiple distributed and heterogeneous sources has long been an important issue in information system research. In this study, we considered the query access and its optimization in such an integration scenario in the context of energy management by using SPARQL. Specifically, we provided a federated approach -a mediato...

Nowadays, the increasing complexity in government-related processes presents considerable challenges to achieve satisfactory services. In this study we will discuss the first results obtained in an ongoing project named “e-Government Innovation Center”. We first identify typical semantic problems in e-Government, then introduce an e-Government sema...

Due to the development of new technologies (digital cameras, smart phones, new data formats, etc.) people are led to deal with an increasing amount of information. Moreover, the advent of the web as a main distribution channel imposes to manage heterogeneous types of data and to deal with the issue of finding efficiently the pertinent information b...

Facebook, Twitter, Youtube,… le Web 2.0 est à présent incontournable ! Il n’en est pas encore de même pour le Web 3.0 ou ce que les spécialistes appellent Web sémantique. Bien que les entreprises perc coivent la force de ces nouvelles méthodologies, elles n’ont pas toutes les compétences pour les mettre en øeuvre. La HES-SO Valais s’est engagée dan...

Né suite à l’appel à projets SmartCity lancé par la HES-SO, l’eGov Innovation Center veut mettre en place un centre de compétences capable de proposer un nouveau modèle d’administration publique durable, innovant et moteur de la transformation de nos villes actuelles en villes intelligentes. Ce projet va combler un réel besoin de synergie en matièr...

The BATIC 3 S project 5 (Building Adaptive Three-dimensional Interfaces for Controlling Complex Control Systems) proposes a method-ology to prototype adaptive graphical user interfaces (GUI) for control systems. We present a domain specific language for the control systems domain, including useful and understandable abstractions for domain ex-perts...

Tangible User Interfaces (TUIs) are emerging as a new paradigm for facilitating user interaction with the digital world by providing intuitive means to link the physical and digital worlds. The MEMODULES project has the objective of developing, experimenting and evaluating the concept of tangible shortcuts (reminders), facilitating (a) the control...

Even in distance learning institutions, the students choose in 80% of the cases paper as data medium. Researches have shown that they are primarily motivated by the mobility of the medium itself and the mobility granted to its user. It seemed interesting to examine to what extent currently available mobile devices can offer the students greater mob...

This paper describes and evaluates a retrieval model that considers the problem of data fusion and collection fusion as two faces of the same coin. To establish a clear theoretical foundation for combining various sources of evidence provided either by different search schemes (data fusion) or by distributed information services (collection fusion)...

With the development of network technology, users looking for information may send a request to various selected databases and then inspect multiple result lists. To avoid the need for inspecting multiple result lists, the database merging strategy merges the retrieval results produced by separate, autonomous servers into an effective, single ranke...
