Abstract
Rough set is a popular theoretical method recently, it could process expression, study and induction of uncertainty or incomplete knowledge and data. According to rough set theory and variable precision rough set model to analyze disadvantages of widely used inverse texts frequency weighting method, and proposed to use variable precision rough set model to establish weight type of feature word weight and a new weight calculation method of double weighting. Experimental conclusions show that the calculation method is valuable in use.
