previously mentioned, as well as collection and data processing techniques from the field of interactional Sociolinguistics and Sociocultural Pragmatics.

A combination of data collection techniques is used to build the corpus of analysis:

- The observer participants technique in various fields where communication professionals work: companies, state and administrative organizations, commercial institutions, media, development companies, youth groups, etc.

- Semi-structured interviews with professionals who have communication roles within the framework of the domains mentioned above.

- Source analysis: texts by professionals aimed both at others from different disciplines and members of the community at large (both within and outside the institutions); manuals created by consulting firms, etc.

It is essential to highlight, as Navarro also argues (2012), that we aspire to work together with researchers and writers in the professional community addressed. The texts collected during fieldwork are intended to make up a sample of the original language, and for this reason, they are neither manipulated or adapted.

The integration of essential tools from the area of Corpus Linguistics (Wynne, 2004; O’Keeffe y McCarthy, 2010) for data processing and subsequent design of the corpus with its respective classifications and the guidelines proposed in this sense for the analysis of specialized discourses by Parodi (2007) are also needed. Likewise, contributions are incorporated from the proposals outlined in Bosio and Sacerdote (2018) and Bosio, Castro, and Cubo (2018).

The data collection and the corpus processing and design parameters include the internal characteristics of the texts and the extra linguistic context in which they are produced and circulate. They are presented below in a tentative list, subject to future revisions, and are based on the results of the fieldwork.

- Contextual and situational aspects: (macro)communicative purpose or function, the scope of circulation (media, company, administrative, commercial, state); spatial-temporal coordinates (deferred, mediated or face-to-face communication); medium; participants involved (social characteristics –age, gender, birthplace, mother tongue–; the level of expertise-layman or not); position held-director, manager, employee-; social roles-symmetrical/asymmetrical, near/far-); the history of the genre.

- Discursive aspects: information contained and development; organization of the information; intensification or weighting, attenuation; modality; specific communication maxims.

- Lexical-grammatical elements: use of particular terminology; syntactic structures that characterize it; appropriate use of punctuation; potential change of code or method of lexical loans.

Regarding the strategies for access to different institutions where the fieldwork is carried out, respective authorizations for personal interviews and formal requests are requested from the directors and people in charge. A signature of informed consent from the professionals who decide to participate in the research is also required. In all cases, different anonymisation techniques are used to preserve their anonymity (Sampson, 2000; De- Matteis, 2014; Cantamutto and Vela Delfa, 2015).
