This paper describes a domain independent approach to automatically constructing information extraction patterns for semi-structured web pages. The approach was tested on three corpora containing a series of tabular web sites from different domains and achieved a success rate of at least 80%. A signi.cant strength of the system is that it can infer extraction patterns from a single training page and does not require any manual labeling of the training page.
