US government communication about the COVID-19 pandemic, particularly ‘Chinese virus’ discourse adopted by Donald Trump and his administration, has led to real-world violence triggered heated discussions across social media sites, including Sina Weibo (aka Chinese Twitter). The current study explores relationship between populism examining how users respond Trump’s on virus. Employing multimoda...

BACKGROUND Acquiring the values of medical professionalism has become a critical issue in medical education. The purpose of this study was to identify lapses in professionalism witnessed by medical students during their four year MD curriculum, and to categorize, from the students' perspective, who was responsible and the settings in which these occurred. METHODS An electronic survey, develop...

It is no coincidence that anti-democratic changes in the recent years Poland occurred alongside rapid development of social media. Technologically advanced methods discourse management (e.g., behavioral targeting) have successfully exploited poor understanding media mechanisms among Poles1 (Drzewiecki, 2010) and created a fertile ground for undermining liberal democracy. Social endangered publi...

Sentences form coherent relations in a discourse without discourse connectives more frequently than with connectives. Senses of these implicit discourse relations that hold between a sentence pair, however, are challenging to infer. Here, we employ Brown cluster pairs to represent discourse relation and incorporate coreference patterns to identify senses of implicit discourse relations in natur...

Previous experimental studies on concessive connectives have only looked at their local facilitating or predictive effect on discourse relation comprehension and have often viewed them as a class of discourse markers with similar effects. We look into the effect of two connectives, but and although, for inferring contrastive vs. concessive discourse relations to complement previous experimental...

BACKGROUND The hype surrounding stem cell science has created a market opportunity for the cosmetic industry. Cosmetic and anti-aging products and treatments that make claims regarding stem cell technology are increasingly popular, despite a lack of evidence for safety and efficacy of such products. OBJECTIVES This study explores how stem cell-based products and services are portrayed to the ...

Studies of discourse relations have not, in the past, attempted to characterize what serves as evidence for them, beyond lists of frozen expressions, or markers, drawn from a few well-defined syntactic classes. In this paper, we describe how the lexicalized discourse relation annotations of the Penn Discourse Treebank (PDTB) led to the discovery of a wide range of additional expressions, annota...

The paper presents machine translation experiments from English to Czech with a large amount of manually annotated discourse connectives. The gold-standard discourse relation annotation leads to better translation performance in ranges of 4–60% for some ambiguous English connectives and helps to find correct syntactical constructs in Czech for less ambiguous connectives. Automatic scoring confi...
