The invention discloses an internet behavior markup engine and a behavior markup method corresponding to the same, and belongs to the technical field of user internet behavior data collection and analysis. The markup engine comprises a classification system module, a word segmentation base module, a semantic analysis module, a crawling program module, a rule base module, a knowledge base module, a rule parser module and a self-learning program module. The internet behavior markup method provides a basic logical structure that user behavior=behavior agent + behavior identification + behavior state. By the engine and the method, classification efficiency and accuracy are improved, description particle size of internet user behavior data is thinned, action, object and environmental conditions of one-time user behaviors are integrally recognized, and internet user behaviors are restored integrally. User behavior data outputted according to IUBML (internet universal behavior markup language) rules directly provide accurate advertising services based on user behaviors and demand understanding, and marketing requirements of corporate clients are met.
