Data Toolbar is an Internet Explorer add-on to collect catalog style information from the web.
Algorithm
The program implements a variation of the genetic tree matching algorithm with respect to nested lists.[1] That is, inside a given website, the program recursively traverses the branches of its DOM tree, aiming to detect nested lists of data items matching the format of the specified content. This approach has several known advantages over a simple string matching algorithm.[2]
Features
- Collection of data and images directly from the Internet Exlorer
- Collection of information from Details pages linked to the catalog
- Automatic processing of multi-page catalogs
- Support of irregular multi-row catalogs mixed with advertisement
