Abstract: In this work we try to classify objects using the MgII 2798 Å line from optical spectra. For that, we use BZQ type objects from BZCAT catalogue. From SDSS catalogues we have 618 BZQ objects which have optical spectra and only in 139 objects there are MgII and Hβ lines simultaneously (z=0.3345-1.0915). By the shape of MgII lines, we grouped these spectra into 3 categories: Broad & Narrow, Broad+Narrow, and Broad.
