The program implements a variation of the genetic tree-matching algorithm with respect to nested lists.Alberto H. F. Laender, Berthier A. Ribeiro-Neto,

This approach is known to have several advantages over a simple string-matching algorithm.Nitin Jindal, Bing Liu [http://www.siam.org/proceedings/datamining/2010/dm10_081_jindaln.pdf A Generalized Tree Matching Algorithm Considering Nested Lists for Web Data Extraction] Proceedings of the Tenth SIAM International Conference on Data Mining, 2010
