A system and method is provided for learning data values over time as they are entered by a user on a form such as a web page form. An Internet web browser can be modified to suggest previously used data values for any form field that is the same as or similar to a previously used form field. Application programs that use the web browser can gain access to previously used form field values even if they have no knowledge of the field names. Software in a web browser associates field names across different Universal Resource Locators (URLs), so that when a user enters a value into a field (e.g., username) at a first web site, that same value can be automatically suggested when the user displays a different form on a different web site that uses the same field name.

A method for determining statistically significant token sequences lends itself for use in the recognition of broken wrappers as well as the construction of new wrapper rules. When new wrapper rules are needed as the underlying wrapped data has changed, training examples are used to recognized data rule candidates that are culled with a bias for rule candidates that would be probably more successful. The resulting rule candidate set is clustered according to feature characteristics, then compared to the training examples. Those rule candidates most similar to the training examples are used to create new wrapper rules.
