Vicente López's research while affiliated with University Pompeu Fabra and other places

... Finally, another research interest is to understand different dynamical emergent aspects of complex networks, such as synchronization, self-sustained activity and pattern formation and to find network adaptation mechanisms. In particular, during my PhD thesis, I have analyzed phase transition phenomena in spiking neural network models [9,23] and derived local learning rules that lead to global self-organization towards critical states [25]. ...

... Moreover, the number of comments that a news item gets is found to be highly skewed and the works have focussed on describing it using powerlaw (Tatar et al. 2012) or log-normal(Manos Tsagkias et al. 2010) distributions. Various studies have been conducted to analyse text content over platforms like Slashdot (Kaltenbrunner et al. 2007), Digg (Szabo and Huberman 2011), (Lerman 2010) or Reddit (Wallenta et al. 2008). Popularity prediction is challenging in such situations owing to factors like complex interactions between users (Gómez et al. 2008), (Jamali and Rangwala 2009), fast peak achievement and quick decay(Szabo and Huberman 2011) and the promotion algorithm being based on collective opinion of users (Lerman and Galstyan 2008) (Tang et al. 2011). ...

... UK-based researchers were amongst the pioneers of the field of corpus linguistics, who originally focused primarily on the English language, although their methodologies are now used widely beyond English. However, Welsh, the second most used language in the UK (Office for National Statistics 2011), lags behind other European languages in terms of corpus provision, with no resource to match, inter alia, the German reference corpus DeReKo (Kupietz et al. 2018), the Czech National Corpus (Kucera 2002), the Croatian National Corpus (Tadić 2002), the ZT Corpus of Basque (Areta et al. 2007) and the CUCWeb corpus of Catalan (Boleda et al. 2006). ...

... Notice that analysing the quality of a debate is a subject of interest (e.g. (Gómez et al., 2008;Gonzalez-Bailon et al., 2010;Aragón, 2019)) when exploiting debates for deliberation (Friess & Eilders, 2015). (ii) Anonymity and Non-Dictatorship. ...

Revista de investigaciones UNAD Bogotá -Colombia No. 01, enero -junio ISSN 0124 793X y relevantes de estudio, de los cuales se tiene referentes son los de Brasil (Modesto et al., 2005), España (Baeza-Yates et al., 2006), Argentina (Tolosa et al., 2007) y Chile (Baeza-Yates y Castillo, 2005;Castillo et al., 2006). En Colombia se tiene antecedentes del investigador Guillermo Correa Uribe (1999), quien enfocó su análisis desde dos puntos de vista: uno técnico y otro visual o de observación personalizada. ...

... First, without a ccTLD, the identification of the 'nationality' websites simply by looking at the structure of the URL becomes a daunting task. Second, without a ccTLD, it is impossible to demarcate or portray the contours of a national web as a network of interlinked urls, as was previously done by various researchers(Baeza-Yates, Castillo, & López, 2005;Ben-David, 2013;Hale et al., 2014;Tolosa, Bordignon, Baeza-Yates, & Castillo, 2007). As a consequence, the lack of such formal and technical boundaries also deems the national history of unrecognized web domains -such as Kosovo's -to partiality. ...

... It suggests the existence of a repertoire of metastable states. Several models have described this [38,39]. It introduces an apparent contradiction, because metastability and hysteresis occur in general at first-order, discontinuous phase transitions. ...

... This should also be valid for online social rhythms, that is, the rhythms of online social activities, which also tend to provide information on peoples' physical rhythms in their everyday lives [14,15]. People's communication activities are often driven by receiving online messages [16,17]. Users in an online communication application may coordinate their online social rhythms to communicate with their online friends. ...
