Syntax Analysis of Serbian Language using Context-free Grammars

Syntax analysis is one of the major phases in natural language processing. This paper presents a method for syntax analysis of Serbian language based on the context-free grammars. First, it describes building a POS tagger for the Serbian language. Secondly, it defines a context-free grammar for Serbian language. The syntax analyzer is implemented by using NLTK tool. Experiments showed that proposed analyzer creates correct syntax trees for 74% of tested sentences.
