Using Sentiment Analysis in Understanding the Information and Political Pluralism under the Chilean New Constitution Discussion
Round 1
Reviewer 1 Report
The proposed article is in line with the expectations of the editors of the special issue. They expected papers whose theoretical, methodological, multidisciplinary, and substantive approaches advance and analyze journalism ethics practices around the world. They are interested in scientific papers which focus on the analysis, study, and description of media ethics in the widest spectrum of professional practices.
Presented paper focused on media and human rights, media ethics, media and law, new technologies in journalism and communications, political behavior in the digital public space.
In keeping with the title “Using Sentiment Analysis in Understanding the Information and Political Pluralism under the Chilean New Constitution Discussion, “the study aims to investigate the forms of concentration such as the communicational flow of digital media to determine the opportunities and information defects of these media due to regulatory deficiencies in this sector. However, for the clarity of the text, it would be useful to specify the research goals more precisely, and especially the unambiguous questions that the authors answer.
In the first part, I propose to put more emphasis on why the authors chose these research methods. It would be particularly important to explain how the measurement of sentiment and keywords can bring us closer to the importance of new media in the fight for pluralism and the fight against concentration and monopolism. To what extent can quantitative methods show the necessity of constitutional changes?
The authors write about the risk of concentration and the lack of media pluralism in Chile, the article lacks empirical data showing the degree of media concentration and the scale of the real threat to media freedom.
In the first part, it would be possible to define the terms of digital media based on literature. In sentence 103, they seem to be synonymous with social media.
In the graphic layer, it would be clearer if the graphs were next to their descriptions. It is worth adding that some graphs, e.g., 4, 5, 7, 9 are illegible. In addition, the charts are in Spanish, which, especially in the case of the Tag Cloud, makes it illegible for a non-Spanish reader.
In the summary, it can be emphasized once more clearly how the analysis of sentiment and the frequency of occurrence of words brings us closer to understanding the Information and political pluralism under the Chilean new constitution discussion.

This article presents an analysis of the public debate on the new constitution in Chile.

Various investigations are cited in the article. The legal context is interesting and timely. But it would be opportune to have the context of digital media in Chile, some data that facilitate the understanding of the subject.

Another weakness is the absence of a systematic review of research on political pluralism, “sentiment analysis”, “social networks and political pluralism” and “social networks and public opinion”. It would be convenient for the author/s to include this type of research.
