What is Corpus Ayotzinapa?
Corpus Ayotzinapa is a collection of journalistic headlines about the Ayotzinapa case, particularly those that reproduce statements from external sources (alien discourse).
Corpus Ayotzinapa is the first freely accessible corpus with its own search engine, specifically designed for the analysis of Mexican journalistic discourse.
Corpus Ayotzinapa is the result of a collective effort aimed at promoting research on Mexican journalistic discourse and facilitating access to news reports on the Ayotzinapa case.
Corpus Ayotzinapa is a research project of the Instituto de Investigaciones Filológicas at UNAM, carried out with the technical support of the Facultad de Ciencias Políticas y Sociales.
What does Corpus Ayotzinapa contain?
The Corpus Ayotzinapa includes all headlines featuring alien discourse that were published as titles for news reports (or mainly informative news stories) on the Ayotzinapa case between September 27 and December 31, 2014, in 29 printed newspapers from Mexico City: 24 Horas, Capital de México, Diario Basta!, Diario de México, Diario Imagen, El Día, El Economista, El Financiero, El Gráfico, El País, El Sol de México, El Universal, Excélsior, Impacto el Diario, La Crónica de Hoy, La Jornada, La Prensa, La Razón de México, Más por Más, Metro, Milenio Diario, Ovaciones, Publimetro, Récord, Reforma, Reporte Índigo, Rumbo de México, The News, and Unomásuno.
As a means of verification—and to further enhance the corpus’s usefulness—each entry includes an image of the digitized text directly from the printed version. When a front-page or section-opening headline refers to another headline inside the newspaper, images of both, along with their corresponding news reports, have been included in the same document. When deemed relevant for interpreting the headline, a reduced version of the full newspaper page has also been included. In some cases, the column layout has been adjusted to improve readability in digital format.
What are the inclusion and exclusion criteria?
a) Only alien discourse headlines have been included—that is, those created from someone else’s statement. All cases in which the processing of speech from any informational source cannot be clearly identified have been excluded. For more information on the categories of alien discourse analysis in journalistic headlines, refer to the book Discurso ajeno en titulares periodísticos: un nuevo modelo de análisis.
b) Only news report headlines or hybrid journalistic genres based on the news report genre have been included. Headlines from other textual genres have been excluded.
c) Only headlines about the Ayotzinapa case have been included—that is, those related to the thematic space of this historical process, which began on the night of September 26–27, 2014, in Iguala, Guerrero, with several episodes of violence in which 43 students from the “Raúl Isidro Burgos” Rural Teachers’ College in Ayotzinapa, Guerrero, were disappeared.
d) Only headlines published between September 27 and December 31, 2014, have been included. Anything published after that date has been excluded.
e) Only the headlines from the 29 mentioned newspapers have been included.
