UrBis: a mobile crowdsourcing platform for sustainable social and urban research in Mexico
(Springer, 2018)"Recently, the United Nations Human Settlements Program (UN-HABITAT) stated that cities in Mexico are steadily expanding, sometimes outstripping the rise in population by two-fold due to urban sprawl, and that 85% of the ... -
Happy and agreeable?: multi-label classification of impressions in social video
(ACM, 2015)"The mobile and ubiquitous nature of conversational social video has placed video blogs among the most popular forms of online video. For this reason, there has been an increasing interest in conducting studies of human ... -
The young and the city: crowdsourcing urban awareness in a developing country
(ICST, 2014)"We present a crowdsourcing study that investigates impressions of urban spaces by young inhabitants in a city in the developing world. Our goal is to obtain collective perceptions from the actual inhabitants of the city ... -
Insiders and outsiders: comparing urban impressions between population groups
(ACM, 2017)"There is a growing interest in social and urban computing to employ crowdsourcing as means to gather impressions of urban perception for indoor and outdoor environments. Previous studies have established that reliable ... -
Looking at cities in Mexico with crowds
(ACM, 2015)"Mobile and social technologies are providing new opportunities to document, characterize, and gather impressions of urban environments. In this paper, we present a study that examines urban perceptions of three cities in ... -
SenseCityVity: mobile crowdsourcing, urban awareness, and collective action in Mexico
(IEEE, 2017)"The SenseCityVity project aims to engage youth in Guanajuato, Mexico, helping them investigate, document, and reflect on urban problems though mobile crowdsourcing. An Urban Data Challenge encourages them to collect ... -
What TripAdvisor Can´t Tell: Crowdsourcing Urban Impressions for Whole Cities
(L'Oeil d'Or, 2016)"In the context of a number of emerging opportunities for citizen participation in Latin America, we present an overview of the SenseCityVity project developed in Mexico. The project goals are the design, implementation, ... -
Síntesis y caracterización de materiales de bismuto y su aplicación en la remediación de agua contaminada
