| Abstract: | Dynamic Web pages are pages which are generated by programs automatically.It is estimated that most Web pages exist in the form of dynamic web pages.This paper puts forward an extraction method based on similar records induction(SRI),which uses string editing distance algorithm and DOM tree alignment algorithm to generate record wrapper.Experimental results show that the extraction method gets a recall of 98.11% and a precision of 96.90% for all kinds of dynamic Web pages. |

| Keywords: | dynamic Web page information extraction wrapper DOM tree |
