Method and system for web information extraction

An article of manufacture comprising:

• a machine readable medium;
• and
• instructions carried by the machine readable medium and operable to cause a programmable processor to perform:
• determining features of a first type for a first web page of a plurality of web pages;
• determining a plurality of rules for an attribute of the first web page, wherein the plurality of rules are determined based on features of the first type;
• identifying a first rule, from the plurality of rules, which satisfies a first predefined criteria, the first predefined criteria comprising at least one of
• a first threshold for a precision parameter,
• a second threshold for a support parameter,
• a third threshold for a distance parameter, and
• a fourth threshold for a recall parameter;
• and
• storing the first rule to enable extraction of value of the attribute from a second web page.

A system comprising:

• a communication interface in electronic communication with one or more web servers comprising multiple web pages;
• a memory that stores instructions;
• and
• a processor responsive to the instructions to
• determine features of a first type for a first web page of a plurality of web pages;
• determine a plurality of rules for an attribute of the first web page, wherein the plurality of rules are determined based on features of the first type;
• identify a first rule, from the plurality of rules, which satisfies a first predefined criteria, the first predefined criteria comprising at least one of
• a first threshold for a precision parameter,
• a second threshold for a support parameter,
• a third threshold for a distance parameter, and
• a fourth threshold for a recall parameter;
• and
• store the first rule to enable extraction of value of the attribute from a second web page.
