“…Analysts may implicitly assume that sentiment analysis results are unbiased because they are automatic but this is not necessarily true. Given the existence of clear gender differences in communication styles on the social web (Burger, Henderson, Kim, & Zarrella, 2011;Mihalcea & Garimella, 2016;Volkova & Yoram, 2015), including for expressing sentiment (Montero, Munezero, & Kakkonen, 2014;Thelwall, Wilkinson, & Uppal, 2010), interpreting sentiment (Guerini, Gatti, & Turchi, 2013) and discussing products (Yang, Kotov, Mohan, & Lu, 2015), gender biases in sentiment analysis seem likely. In other words, sentiment analysis algorithms may be more able to detect sentiment from one gender than from another so that, in a gender-mixed collection of texts, sentiment analysis results could over represent the opinions of one gender.…”
