This chapter first introduces the selection criteria applied to the corpora and describes the texts submitted to analysis. Afterwards it gives the selection criteria applicable to the participants of the research, discusses the procedures of choosing the participants and introduces the oral interviews with the participants as part of the procedures of participant-related data collection and, finally, describes the participants. Subsequently, the chapter discusses the translation assignment. This will be followed by the demonstration of the application of the Political Bias Screener: the analysis of super- and macrostructure with the Screener will be demonstrated first. The application of the CDA and political mass communication components of the Screener will not be demonstrated in this chapter as these constituent models of the analytical tool are interpretative in nature and thus concern entire discourses as meaningful units of analysis. Therefore, no text segment can be taken from the corpus that would provide a meaningful demonstration of the procedures of analysis without presenting the rest of the given text (cf. Sections 4.5.1 and 4.5.2; for a detailed presentation of these analyses, see Section 8.4). Finally, as the current study constitutes the first attempt at testing the analytical tool, this chapter will touch upon the question of reliability in connection with the functioning of all the four constituent models of the Political Bias Screener.
