概要	Simulation-assisted quantitative content analysis (SA-QCA) extends classical quantitative content analysis by integrating computational simulation — typically Monte Carlo methods or agent-based models — to validate coding schemes, estimate coder reliability under controlled conditions, test category distinctiveness, and assess the robustness of frequency-based conclusions before or alongside the analysis of real text corpora. The method preserves the systematic, replicable counting logic of quantitative content analysis while adding a simulation layer that strengthens methodological rigour.	Quantitative content analysis is a systematic, replicable method for converting the manifest content of text, images, or other recorded communication into numerical data. By applying a pre-specified codebook to a defined corpus and counting or scaling the resulting categories, researchers obtain frequency distributions, proportions, and relationships that can be subjected to standard statistical tests. It is the dominant method for large-scale, objective analysis of media, documents, social media posts, policy texts, and similar materials.
