Abstract: An intelligent workflow management system should have the ability to dynamic analyze and optimize workflow process to improve performance and efficiency．This paper presents a semantic-based workflow optimization method，which uses ontology to describe the concept of the workflow，endows the workflow model with corresponding dynamic semantic，so as to construct a workflow fact library； by defining a set of classification rules of activity，to classify all of the workflow activities semantically and construct a library of classification rules； by performing these classification rules，to acquire optimized information，and performing corresponding operation according to different activities，so as to optimize the structure of the workflow model.An example is given to illustrate the feasibility and correct of the method.
