December, 2022.- With productive work meetings, in which the participants were divided by topics of interest and specialization, the Workshop of PE2 and PE3 of the Millennium Institute Foundational Research on Data culminated, held at the headquarters of the University Federico Santa María in Valparaíso.

In this, about 40 researchers and students gathered participated, whose topics are related to the work of both emblematic projects: Creation of new query languages for information networks (PE2) and Efficient extraction of highly complex data (PE3).

The researchers’ presentations were:
