[Objective] This paper tries to build domain ontology for intelligent applications, aiming to enhance the capability of domain knowledge representing and application development. [Methods] We proposed the application-driven circulation method to model cross-domain knowledge based on the demands of intelligent applications. It has the structure of “requirement + construction + evaluation”, so that requirements play leading role in ontology construction. We took the field of anti telephone fraud as an example, and constructed the anti-fraud ontology of the intelligent requirements. [Results] Our anti-fraud domain ontology represented a wide range of cross-domain knowledge and effectively supported intelligent anti-fraud applications, which were based on the semantics of fraudulent calls. [Limitations] More research is needed to examine the requirements of intelligent applications. [Conclusions] The proposed method promotes more research in domain ontology construction and anti-fraud methods.
