Page Model

ONE_HTML_PAGE ::= List( RESTAURANT )

RESTAURANT ::= < Name, Address, Phone, Review, List(Credit_Card)>

NOTE:

each HTML page is seen as a list of restaurants, and each restaurant description contains an embedded list of credit cards. In database terms, an HTML page represents a table with five columns (i.e., Name, Address, Phone, Review, List(Credit_Card)), where the last column is an embedded table that has exactly one column. The wrapper must be able to identify each individual credit card, so that one can use the extracted data to answer queries like give me all Thai restaurants that accept VISA.

Items to be extracted: Name, Address, Phone, Review, Credit_Card.
