Abstract

The World Wide Web is now undeniably the richest and most dense source of information, yet its structure makes it difficult to make use of that information in a systematic way. This paper extends a pattern discovery approach called IEPAD to the rapid generation of information extractors that can extract structured data from semi-structured Web documents. IEPAD is proposed to automate wrapper generation from a multiple-record Web page without user-labeled examples. In this paper, we consider another case when multiple Web pages are available but each input Web page contains only one record (called singular Web pages). To solve this case, a hierarchical multiple string alignment is proposed to allow wrapper induction for multiple singular Web pages.
