World Wide Web: Largest known repository of documents containing diverse content used by people from diverse backgrounds.
Few characteristics of Web include:
Observation 1: Data records displayed in a particular region of a Web page are contiguous and are formatted using similar HTML tags. [Liu 03]
Observation 2: A group of similar data records belonging to a particular region are always present under the same parent node in the tag tree. [Liu 03]
Observation 3: Every record present in most search response pages has at least one hyperlink. Usually, title of the retrieved document is displayed in the form of a hyperlink, which points to the retrieved document. In this work, we refer to such a hyperlink as a record link.
