Abstract: Event factuality refers to the level of event factual information expressed by event narrator and it is the foundation of natural language understanding.During the research,we focused on identifying Chinese event factuality and proposed an effective identification approach based on features.It extracts and transforms features from the factual related information.Meanwhile,considering the relationship between parts of features and event factuality,it makes a fusion of these features according to rules.Experimental results manifest that our approach achieves a higher performance than the rule-based approach for the task of event factuality identification.

Key words: Event factuality,Identification approach,Feature transformation and fusion
