Claim:
A computer-related method of information extraction from a Web page using a broken wrapper, comprising: wherein a wrapper comprises a set of rules for extracting information from HTML context of strings and for assigning labels from a wrapper set of labels to the extracted information; wherein a broken wrapper comprises a wrapper in which HTML context of at least one string cannot be used to classify the at least one string; extracting strings from the Web page parsed in a forward direction using the broken wrapper; for each extracted string t: analyzing the extracted string t according to a set of rules for assigning labels associated with the broken wrapper; if a matching rule with a label l w exists for the extracted string t, validating the label l w with a content classifier C, which classifies the extracted string t based on content features of the labeled extracted string; and if the classifier C validates the label l w for extracted string t within some threshold value, then assigning label l w , to extracted string t, else not assigning l w to t.
