SUMMARY The 2019 protests revealed to the world an enormous gap between the outcomes of the Chilean democratic system and the social demands of ordinary Chileans.

ABSTRACT: To avoid the “meaning conflation deficiency” of word embeddings, a number of models have aimed to embed individual word senses. These methods at one time performed well on tasks such as word sense induction (WSI), but they have since been overtaken by task-specific techniques which exploit contextualized embeddings. However, sense embeddings and contextualization need…
ABSTRACT A key hypothesis in epidemiological studies is that time to disease exposure provides relevant information to be considered in statistical models However, the initiation time of a particular condition is usually unknown So, we developed a multiple imputation methodology for the age at onset of a particular condition, which is supported by incidence data…

ABSTRACT: This workshop will seek to investigate the linkage between popular discontent, polarization, and the emerging of ‘populist’ options that stretch across very different political offers.

ABSTRACT: Between 2010 and 2020, conventional wisdom on social media has changed dramatically, from being celebrated as prodemocratic platforms to being held responsible for the rise of polarization, misinformation, and populism. Contrary to utopian and dystopian perspectives, I find that the effects of social platforms on individuals’ cognitions, attitudes, and behaviors are decidedly mixed. Using…
