Media bias is studied at schools of journalism, university departments (including Media studies, Cultural studies and Peace studies) and by independent watchdog groups from various parts of the political spectrum. In the United States, many of these studies focus on issues of a conservative/liberal balance in the media. Other focuses include international differences in reporting, as well as bias in reporting of particular issues such as economic class or environmental interests. Currently, most of these analyses are performed manually, requiring exacting and time-consuming effort. However, an interdisciplinary literature review from 2018 found that automated methods, mostly from computer science and computational linguistics, are available or could with comparably low effort be adapted for the analysis of the various forms of media bias. Employing or adapting such techniques would help to further automate the analyses in the social sciences, such as content analysis and frame analysis.
