New Phrase Chunking Algorithm for Myanmar Natural Language Processing

Abstract:

Chunking is the subdivision of sentences into non recursive regular syntactical groups: verbal chunks, nominal chunks, adjective chunks, adverbial chunks and propositional chunks etc. The chunker can operate as a preprocessor for Natural Language Processing systems. This study aims to proposed new phrase chunking algorithm for Myanmar natural language processing. The developed new algorithm accepts Myanmar tagged sentence as input and generates chunks as output. Input Myanmar sentence is split into chunks by using chunk markers such as postpositions, particles and conjunction and define the type of chunks as noun chunk, verb chunk, adjective chunk, adverb chunk and conjunction chunk. The algorithm was evaluated with POS tagged Myanmar sentences based on three measures parameters. According to the results, good accuracy of Precision, Recall and F-measure were obtained with new developed algorithm.
