Research of a Tree Structure Based Fully Automatic Wrapper Method
LI Ya-qiao · Journal of Hebei University of Technology · 2007
This paper investigates the wrapper generation problem under a new perspective. Our system works with two trees at a time, pattern discovery is based on the study of similarities and dissimilarities between the trees, mismatches are used to indentify the wrappers. The intensive experiments on real Web sites show that the approach with tree automata compared favorable against some other approaches in finding of the structured data with optional and iterator.
