The invention discloses a method for unblocking a touch screen device and the touch screen device. Due to the fact that predetermined unblocking tracks, an icon, a main interface window and a user operating authorization are related, a user can acquire different icons, different main interface windows and different grades of user operating authorizations after unblocking the touch screen device by adopting different unblocking tracks. Therefore, the novelty of application interfaces of the touch screen device is guaranteed, and security and confidentiality of the touch screen device are increased. Meanwhile, the user can define the predetermined unblocking tracks, the icon and the main interface window by himself, accordingly, the user can set the unblocking tracks and the application interfaces according to his own situation, the demand for personalization of the user is fully met, and the user can operate the touch screen device conveniently.

To overcome the defect in prior art, the related method considers fully the relation between sentences and the relation between sentence and user query to generate the abstract both with main file information and topic explanation or query answer, and applies difference penalty algorithm to ensure the novelty of abstract. This invention can meet individual request.
