【 摘 要 】

This paper studies the problem of wrapper generation and proposes the concept of visual-relational data extraction as the foundation for modeling wrappers. Towards large scale integration, we identify the key requirements of wrapper deployment, and observe the limitations of the state of the art| which inherently result from their low-level wrapper modeling. We thus propose the visual-relational modeling and develop the execution and learning mechanisms. Our experiments show signi cant improvements towards satisfying the accuracy and consistency requirements.
