Automatic discovery of semantic structures in HTML documents
Saikat Mukherjee, Guizhen Yang, Wenfang Tan, I. V. Ramakrishnan · 2004
Template-driven HTML documents possess an implicit, fixed schema denoting concepts and their relationships in a hierarchical fashion. Discovering this schema remains a relatively unexplored problem. By exploiting a key observation that semantically related items in HTML documents exhibit spatial locality, we develop an algorithm for automatically partitioning them into tree-like semantic structures which expose the implicit schema.
