Crowdsourcing Cultural Heritage: From 3D Modeling to the Engagement of Young Generations

2016

Monitoring, digitizing and archiving museum artworks represent an important socio-cultural accomplishment and an overcoming in digital preservation today. Cultural heritage is constantly under threat of terrorist attacks and natural disaster. The high costs related to documentation task have prevented a constantly and massive survey activity. The low cost 3D image based acquisition and elaboration techniques of an object, allow to carry out a 3D photorealistic model in a short time. Therefore, a lot of museum adopted these techniques for the artworks archiving. Crowdsourcing activities can significantly speed up survey and elaboration procedures. If, on the one hand, these initiatives can h…

Big Data in Emergency Management: Exploitation Techniques for Social and Mobile Data

2020

The Internet of Things, crowdsourcing, social media, public authorities, and other sources generate bigger and bigger data sets. Big and open data offers many benefits for emergency management, but also pose new challenges. This chapter will review the sources of big data and their characteristics. We then discuss potential benefits of big data for emergency management along with the technological and societal challenges it poses. We review central technologies for big-data storage and processing in general, before presenting the Spark big-data engine in more detail. Finally, we review ethical and societal threats that big data pose.

Citizens AND HYdrology (CANDHY) : conceptualizing a transdisciplinary framework for citizen science addressing hydrological challenges

2021

Widely available digital technologies are empowering citizens who are increasingly well informed and involved in numerous water, climate, and environmental challenges. Citizen science can serve many different purposes, from the "pleasure of doing science" to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water management problems. Still, procedures on how to incorporate citizens' knowledge effectively to inform policy and decision-making are lagging behind. Moreover, general conceptual frameworks are unavailable, preventing the widespread uptake of citizen science approaches for more participatory cross-sectorial water go…

The role of Intellectual Property Rights in the value capturing of crowdsourcing for innovation contests

2017

In this study, we investigate the role of IPR arrangements in crowdsourcing for innovation challenges. Integrating Property Rights Theory and the open innovation literature, we propose that specific challenge attributes affect the seekers organizations’ choice between alternative IPR arrangements and how this choice, in turn, affects the self-selection of external solvers into solving the challenge. We collected multi-source, interview data with open innovation directors and we built a unique data set of 729 awarded challenges broadcasted on InnoCentive platform from 2010 to 2016. Our findings contribute to the emerging literature on open innovation and crowdsourcing literature by bringing …

Découverte des relations dans les réseaux sociaux

2011

In recent years, social network sites exploded in popularity and become an important part of the online activities on the web. This success is related to the various services/functionalities provided by each site (ranging from media sharing, tagging, blogging, and mainly to online social networking) pushing users to subscribe to several sites and consequently to create several social networks for different purposes and contexts (professional, private, etc.). Nevertheless, current tools and sites provide limited functionalities to organize and identify relationship types within and across social networks which is required in several scenarios such as enforcing users’ privacy, and enhancing t…

A Novel Recruitment Policy to Defend against Sybils in Vehicular Crowdsourcing

2021

Vehicular Social Networks (VSNs) is an emerging communication paradigm, derived by merging the concepts of Online Social Networks (OSNs) and Vehicular Ad-hoc Networks (VANETs). Due to the lack of robust authentication mechanisms, social-based vehicular applications are vulnerable to numerous attacks including the generation of sybil entities in the networks. We address this important issue in vehicular crowdsourcing campaigns where sybils are usually employed to increase their influence and worsen the functioning of the system. In particular, we propose a novel User Recruitment Policy (URP) that, after extracting the participants within the event radius of a crowdsourcing campaign, detects …

2015

Spanish Abstract: Las nuevas plataformas virtuales estan cambiando la forma en la que se presta servicios. La tecnologia esta trasformando las organizaciones empresariales de forma que el trabajador subordinado es menos necesario. Un nuevo tipo de empresas --"on demand, economy "sharing economy"-- se dedican a conectar al cliente directamente con el prestador de servicios. De esta forma, estas companias desarrollan su principal actividad a traves de trabajadores autonomos. En este contexto, el Derecho del trabajo se enfrenta a su mayor desafio, teniendo que regular una realidad muy diferente a la existente en el momento en el que fue creado. Sin embargo, los trabajadores siguen necesitando …

Scenarios on Adoption of Open Source Software in the Communications Software Industry

2011

We examine the trends and developments affecting the adoption of open source software in the communications software industry. Based on expert interviews and scenario analysis, four alternative and possibly co-existing scenarios are derived. The analysis suggests that communication service providers will mostly deploy open source software in infrastructure software. Alternative developments include use of open source software in launching new services and in cloud computing. The present study is relevant particularly for technology managers considering open source strategies.

How can I signal my quality to emerge from the crowd? A study in the crowdsourcing context

2022

Crowdsourcing contests are characterized by an intensive level of competition because of the extensive number of solvers that voluntarily self-select to participate in such contests. This study aims at understanding how solvers can signal their quality attributes through the community functionalities, i.e. the online profile and the discussion blog of the crowdsourcing platform, to improve their chances of winning crowdsourcing contests. Drawing on signaling theory, we hypothesize that signaling their skills and capabilities by crafting profiles rich in personal and professional information and by participating actively within the discussion blog by posting and commenting, solvers can influ…
