Using a hybrid method to recognize the predicate head of a Chinese sentence

Recognizing the predicate head is an important part of the syntactic analysis of Chinese sentences. We present a new hybrid approach to recognize the predicate head automatically, which consists of two main steps: we use a rule-based method to coarsely filter the quasi-predicate that may be the predicate of a sentence; then use a multi-feature-based method to decide the real predicate by acquiring a great diversity of features with different weights from the training set. The result of experiments indicates that this approach is feasible and advanced.
