....from labeled training tuples. In Wrapper induction [14] the author manually defines six wrapper classes, which consist of knowledge to extract data by recognizing delimiters to match one or more of the classes. The richer a wrapper class, the more probable it will work with any new site [6]. SoftMealy [11] provides a GUI that allows a user to open a Web site, define the attributes and label the tuples in the Web page. The common disadvantages of IE systems are the cost of templates, domain dependent NLP knowledge, or annotations of corpora generated by hand. This is why these ....

....generate negative data is an interesting variant of this approach: essentially, one LGG predicate is selected as a candidate span generator, and subsequent predicates are used to filter these candidates. Certain other extraction systems cast extraction as an automata induction problem [Hsu, 1998; Chidlovskii, 2000] This sort of approach requires a commitment to one particular sequential view of the document: e.g, as a sequence of tokens. The approach taken here is somewhat more flexible, in that the document can be viewed (by different builders) as a DOM tree or as a token sequence. Many of the ideas ....
