To improve the accuracy of the correlation calculation between the webpage and a specific topic,a webpage-topic correlation calculation model(OBWTCCM)based on the domain ontology was proposed.The topic was described using the domain ontology,and a topic semantic matrix was built after extracting the topic concepts by computing the semantic relation between the concepts in the ontology.Then the correlation between the webpage and the topic was calculated by combing the matrix and the statistics information of feature words.This model improves the vector space model by adding the consideration in the semantic level.The application of the method in the real project indicates that the result overall fits the judgments of the domain experts and has a satisfied accuracy rate in the correlation calculation.
