Currently, very less NLP tools are available to parse several Indian languages. Hence, an effort has been made by us to efficiently parse the structure of the complex sentences in Kannada text using CYK algorithm. It is a bottom-up dynamic programming approach which functions only with the ...

More technically, our main result is achieved by transforming the parsing table at the base of the CYK algorithm, introduced in Section 3.1, into two square matrices of fixed size, defined over real numbers, in such a way that the basic operations of the CYK algorithm can be implemented ...
