We propose a novel approach for extracting semantic structures from Web documents. Our task is to extract trees that describe the hierarchical relations in documents. We developed an algorithm for this task by using the stochastic context free grammar (SCFG) framework. Experiments showed that our approach effectively worked showing performance improvement through the parameter estimation.
