Domain-oriented web data extraction and integration is the basis of providing val- ue added services, and is also a major research direction in the field of web data mining. In com- bination with the requirement of the field, we proposed the domain-oriented web data extraction and integration architecture. Based on the concepts of web data model and web data pattern, do- main data model and domain data pattern, the mapping method of web data pattern and domain data pattern and integration method on data level are proposed to solve the conflict problem of pattern layer and data layer in the integration process. We also discussed the implementation method of web data extraction and domain value added services. Real estate information platform and integrated application system are developed with the actual requirements, and the effective- ness of the model and algorithm is verified.
