Chinese partial parser for automatic extraction of verb grammatical collocations

Grammatical collocation is one of the important lexical knowledge for NLP and getting it automatically is useful for many applications. We present a parser based on phrases to extract grammatical collocations of Chinese verbs. Under the instruction of collocation templates, the parser combine base phrases to common phrases, and to grammatical collocation chunks with a chart-parsing algorithm. In the algorithm, we apply a new process sequence referring to the special task, which starts from each verb, then processes to the left and right. In this way, we are able to achieve precision of 61.4%, 55.4% and 54.8% for science, news and novel corpus respectively.
