  Young stellar objects in their pre-main sequence phase are characterized by
irregular changes in brightness, generally attributed to an increase of the
mass accretion rate due to various kind of instabilities occurring in the
circumstellar disk. In the era of large surveys aimed to monitor the sky, we
present a pipeline to detect irregular bursts, in particular EXors-like ( EX
Lupi type eruptive variables), in the light curves. The procedure follows a
heuristic approach and is tested against the light curves already collected for
a few objects presently recognized as bona fide or candidate EXors.
