We propose a new technique to infer the structure and extract the tokens of data from the semi-structured web sources which are generated using a consistent template or layout with some implicit regularities ...
The attributes are extracted and labeled reversely from the region of interest of targeted contents. This is in contrast with the existing techniques which always generate the trees from the root. ...
THE REVERSE MECHANISM No matter the method used to extract and to label the tokens from a web template or layout, correct initial setup is crucial for further data extraction. ...

Data extraction from web pages is performed by software modules called wrappers. Recently, some systems for the automatic generation of wrappers have been proposed in the literature. ...
However, due to the automatic nature of the approach, the data extracted by these wrappers have anonymous names. ...
We have then used these wrappers to extract data from the input pages. Finally, we have run Labeller to annotate the extracted data with a label extracted from the input pages. ...
