Abstract: In recent years,the study of the rules engine has achieved fruitful results.It brings new ways and ideas to the processing of Chinese complex sentences.In this paper,we designed a rule engine for automatic identification of relationalwords in Chinese complex sentences.A pattern-matching strategy to select relation words set,a’eliminate contains maximizing strategy’ to eliminate the conflict rules,and a ‘front cover strategy’ to select final result were designed.By using the three strategies in rule engine,the efficiency and accuracy of identification of relational words in Chinese complex sentences are improved.
