“…But this only works if the underlying sentiment weights adequately reflect term usage in the political context of interest. The technically more advanced literature recently offered context-specific machine-learning approaches (e.g., Ceron, Curini, & Iacus, 2016;Hopkins & King, 2010;Oliveira, Bermejo, & dos Santos, 2017;Van Atteveldt, Kleinnijenhuis, Ruigrok, & Schlobach, 2008), sometimes paired with crowd-sourced training data (Lehmann and Zobel 2018;Haselmayer & Jenny, 2017), in this regard. Yet, especially in projects where expressed sentiment is only one variable in a broader analytical setup, the computational, financial, or human resources required for such approaches can quickly offset the comparative advantages that led to conducting an automated analysis in the first place.…”
