**2.3 Third phase (selection of the articles in the languages of interest)**

The list of eligible articles will be drawn up, and the concordance with the established objectives should be evaluated to avoid invalidating the results of the systematic reviews.

This list of eligible articles will be organized in a matrix with a degree of concordance; it will be identified qualitatively and quantitatively by identifying the titles and abstracts (**Figure 2**).

Very concordant = The title of the article and the research question have a clear relationship with the topic of artificial intelligence, expert systems, and description of uses.

Relatively concordant = The title of the article and the research question are partially related to the subject of artificial intelligence, expert systems, and description of uses.

not concordant = The title of the article is not related to the research question, subject of Artificial intelligence, expert systems, and uses.
