Abstract
The paper investigates techniques for extracting data from HTML sites through the use of auto- matically generated wrappers. To automate the wrapper generation and the data extraction pro- cess, the paper develops a novel technique to com- pare HTML pages and generate a wrapper based on their similarities and differences. Experimental results on real-life data-intensive Web sites con- firm the feasibility of the approach.File in questo prodotto:
