c. Wrapper maintenance
Wrappers facilitate access to Web-based information sources by providing a uniform querying and data extraction capability. When wrapper stops working due to changed in the layout of web pages, our task is to automatically reinduce the wrapper. The data sets used for experiments in our JAIR 2003 paper contain web pages downloaded from two dozen sources over a period of a year.
