  • QUOTE: Traditionally, when one wants to learn about a particular topic, one reads a book or a survey paper.

The proposed techniques first identify those sub-topics or salient concepts of the topic, and then find and organize those informative pages, containing definitions and descriptions of the topic and sub-topics, just like those in a book.
