This paper proposes an interactive wrapper learning approach to Web information extraction for semi-automatic wrapper generation. In particular, we present an algorithm that learns patterns based on the structure of training instances using tree alignment techniques. This
is achieved by generating structural template models for both positive and negative examples. We evaluate our system on standard benchmarks, and evaluation shows that there exists great potential for structure learning for a variety of extraction tasks.
