Within the scope of the present undertaking a text-type translation oriented analytical tool has been developed for the identification and comparison of political and ideological bias in source and target texts. The analytical tool called Political Bias Screener, which focuses on argumentative political newspaper articles and their translations in a political mass communication context, incorporates four models: 1) Hoey’s (2001) Problem-Solution Model 2) for the analysis of superstructure, 2) Tirkkonen-Condit’s (1985) Macrostructure Model for the analysis of macrostructure, 3) the Translation-centred Discourse–Society Interface Model for the Critical Discourse Analysis of source and target texts and 4) the Translation-centred Political Mass Communication Model for the interpretation of the CDA results in the context of political mass communication, which the source newspaper articles and their translations are part of. A hierarchical relationship holds between the four constituent models of the analytical tool: the output of a given constituent serves as the input of the following constituent (cf. Chapter 6.4). In the current research, the analytical tool has been tested for validity and reliability in the scope of the analysis of the two Hungarian source language argumentative political newspaper articles and their eight English target language translations.
