Semi-Automatic Wrapper Generation for Internet Information Sources

13 years 11 months ago
Semi-Automatic Wrapper Generation for Internet Information Sources
To simplify the task of obtaining information from the vast number of information sources that are available on the World Wide Web (WWW), we are building tools to build information mediators for extracting and integrating data from multiple Web sources. In a mediator based approach, wrappers are built around individual information sources, that provide translation between the mediator query language and the individual source. We present an approach for semi-automatically generating wrappers for structured internet sources. The key idea is to exploit formatting information in Web pages from the source to hypothesize the underlying structure of a page. From this structure the system generates a wrapper thatfacilitatesquerying ofa source and possibly integrating it with other sources. We demonstrate the ease with which we are able to build wrappers for a number of Web sources using our implemented wrapper generation toolkit.
