Method and system for searching documents using readers valuation

摘要

A method and system for ranking pages using valuations from readers is disclosed. A reader's time spent on a page is tracked, normalized on the length of the document, capped to limit the effect of one individual, and a reader valuation score of the page comprising the time is updated. Higher value of reader valuation score of a page represents longer time reader(s) spent on the page and therefore higher value to the reader(s). Pages containing relevant keywords can then be sorted by reader valuation scores. Reader valuation scores of pages can be maintained in a private account to help a reader more effectively organize his or her reading history, or be maintained for public to represent general readers' valuations on pages, or be maintained in groups of readers with attributes such as profession, educational level, age, sex to represent special group of readers' valuations on pages.
