Mexico uses artificial intelligence to search for people who have disappeared

The newspaper points out that this program was developed by the National Search Commission (CNB) to identify patterns and clues that would help locate missing persons in the so-called dirty war of the second half of the last century.

He adds that this system already stores thousands of documents from that period, and while information continues to be fed and progress made in processing, it made its first contributions in the work of the Access to Truth Commission, historical clarification and promoting justice for gross human rights violations committed between 1965 and 1990.

Specifically, during the inspections carried out in September 2022 at military camp number 1, “an emblematic site of the enforced disappearances of the time”.

La Jornada interviewed specialist Javier Yankelevich, director of search operations at CNB, who leads the multidisciplinary team developing the program, which includes computer scientists and biomedical scientists.

Angelus, he said, resulted from the amount of information available about that period, which could not be managed without the help of a computer system, since there was documentation on the perpetrators, such as officials from the extinct Federal Security Directorate and the Army, witness statements, scientific studies, Press of the time, among many others.

Moreover, he added, it arose because there is a great relationship between the victims’ cases in that they are the same profile, same period, same perpetrators.

In 2020 the first already programmed version of the Angelus system was created, in early 2021 it was used as an information organization tool and is currently used by more than 40 analysts.

The historian explained that the system has one interface for uploading documents, another for processing, and another for querying the database where the information is organized as a network.

Regarding the future of the system, Víctor Mireles, head of programming, explained that advances are being made so that this technology can carry out what is known as automatic tracking, that is to say that it proposes relationships between information that is not currently available.

He stressed that a similar system did not previously exist in Mexico and that countries such as Chile have shown interest in it, in this case for the search for those who disappeared during the dictatorship of Augusto Pinochet (from 1973 to 1990).
