The project is aimed at constructing a formal model of agreement in Russian.

The problem of agreement modeling has several aspects. The first aspect is the limits of agreement as a model of syntactic interaction. The model should fully reflect the core instances of agreement as long as the relevant phenomena that show similar restrictions. The second aspect deals with the inner structure of agreement model and its parametrization: which components may be involved in the agreement relation and what characteristics they have, which features agreement relation may be established for, etc. Agreement model should be both flexible enough to allow parametric variation of the agreement mechanism based on a set of formal features, and restrictive enough to effectively limit this variation. We believe that the study of the attested variation in agreement can be a convenient research tool for identifying the parametric properties of agreement.
