The Understandability of Phrases and the Grammatical Parsing

This paper introduces a new concept of the understandability of phrase and applies it in the standard grammatical parsing of natural language sentence. The concept of the understandability of phrase in turn is established based on the concept of the weak consistency of knowledge which reflects the essential of how people semantically determine the validity of phrases. By improving the parsing probability of the understandable phrases, the semantically correct parsing tree may obtains the largest parsing probability and thus the accuracy of the grammatical parser could be improved eventually
