สรุป	Bayesian quantitative content analysis systematically codes and counts features in textual or media content, then quantifies patterns and tests hypotheses using Bayesian statistical inference. Unlike classical frequency-based content analysis, it incorporates prior knowledge or domain expectations into the estimation process, producing posterior probability distributions over content parameters rather than single point estimates with p-values. The approach is particularly valuable when prior research, expert knowledge, or pilot data exist and when uncertainty quantification around content proportions and category frequencies is important.	Comparative quantitative content analysis is a systematic, replicable method for counting and categorizing features of communication content — such as news coverage, social media posts, or policy documents — across two or more groups, time periods, outlets, or countries. By applying a standardized codebook to each comparison context, it reveals patterns of similarity and difference in how topics, frames, actors, or sentiments are represented, and allows statistical testing of those differences.
