Two editorials from the Brazilian science magazine Ciência Hoje, one from the 1980s and one from the 1990s, serve as the object of investigation. The data was used in a research paper by Luiz Rosalvo Costa to explore relations between discourse and ideology using Bakhtinian theory. The dataset is available via the paperswithcode platform under an Open Access (green) license.
Use Cases
- Analyzing ideological clashes in scientific communication based on the described editorial texts.
- Applying Bakhtinian discourse analysis frameworks to media texts based on the described research focus.
- Studying the evolution of scientific dissemination rhetoric over time based on the two-decade time span mentioned.
- Training text classification models to identify ideological markers in science journalism based on the annotated editorials.
Strengths
- Focuses on two specific, temporally distinct editorials from the 1980s and 1990s, providing a comparative basis.
- The research context is clearly defined, linking the data to a specific theoretical framework (Bakhtin Circle).
Limitations
- The dataset consists of only two text samples, which may limit statistical analysis.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
