Comparatively crawling web page data records relative to a template
摘要:
The invention provides a method of interactively crawling data records on a web page. Users may select various data records of interest on a web page to generate templates to search for similar data items on the same web page or on different web pages. A tree matching algorithm may be used to compare and extract data matching the generated template.
