  Conspiracy Theory Identication task is a new shared task proposed for the
first time at the Evalita 2023. The ACTI challenge, based exclusively on
comments published on conspiratorial channels of telegram, is divided into two
subtasks: (i) Conspiratorial Content Classification: identifying conspiratorial
content and (ii) Conspiratorial Category Classification about specific
conspiracy theory classification. A total of fifteen teams participated in the
task for a total of 81 submissions. We illustrate the best performing
approaches were based on the utilization of large language models. We finally
draw conclusions about the utilization of these models for counteracting the
spreading of misinformation in online platforms.
