“…Although the term "automated content analysis" in general encompasses a wide variety of forms (e.g., Grimmer & Stewart, 2013;Hopkins & King, 2010;Krippendorff, 2013), our definition inevitably excludes automatic approaches of merely acquiring data, data entry, or data management other than the actual coding or classification process (e.g., Lewis, Zamith, & Hermida, 2013). Instead, we concentrate on two broad and rather common formsa dictionary (lexicon-based) approach and a supervised machine learning (SML) approach (see Boumans & Trilling, 2016;Grimmer & Stewart, 2013). As we shall elaborate below, they are rather sensitive to the issue of imperfect gold standards, although the two approaches may nontrivially differ in terms of the degree of their potential sensitivity to this issue.…”
