1. A computer-implemented method for text analysis, comprising: identifying a sentence; identifying a graph of generalized constituents for the sentence based on rough syntactic analysis of the lexical-morphological structure of the sentence, the graph of generalized constituents comprises arcs and nodes; filtering the arcs of the graph of generalized constituents using a combination classifier; identifying a syntactic structure of the sentence by performing precise syntactic analysis of the sentence based on the filtered graph of generalized constituents of the sentence.
