# Syntax Analyzer

Node.js adoption of https://github.com/constantin50/syntax_analyzer

This is syntax analyzer for Russian based on context-free grammar. 
It uses OpenCorpora dictionary of labelled words and AZ module as interface. 

The repository consitsts of two main parts: 

(1) parse_tree - class of binary tree to represent structure of sentence

(2) analyzer - parser that takes raw sentence and returns set of possible parse-trees

There are also complements: 

grammar.json - context-free grammar for russian

dict - dictionary of some complex phrases (conjugations, predicatives, adverbs etc.) that don't present in OpenCorpora dictionary.


# Example:

node run.js "Я пишу письмо старому другу"

    S     
       NP[case='nomn'] 
           
           Я ['NPRO', 'sing', '1per', 'nomn']
           
    VP[tran]
     
     VP[tran]
               
               VP[tran] 
                       
                       пишу ['VERB', 'sing', '1per', 'tran', 'pres']
               
               NP[case='accs'] 
                       
                       письмо ['NOUN', 'sing', 'neut', 'accs']
     
     NP[case='datv']
               
               NP[case='datv'] 
                       
                       старому ['NOUN', 'sing', 'neut', 'datv']
               
               NP[case='datv'] 
                       
                       другу ['NOUN', 'sing', 'datv']
