Method for judging cheat clicking of mobile phone advertising

The invention discloses a method for judging cheat clicking of mobile phone advertising. The method includes acquiring at least one piece of information in different dimensions on the basis of a built-in sensor of a mobile phone when a user clicks a screen; processing the information on the basis of respective data probability computing models to obtain respective corresponding probabilities of true clicking; processing the respective corresponding probabilities of true clicking by the aid of a regression model and computing the probability of current cheat clicking. The pieces of information in the different dimensions includes information of the clicking position of the current clicking of the mobile phone advertising, vibration change and sound change before and after the clicking, change of intersection points of the eyeballs of the user in an advertising zone and change of longitudes and latitudes of the mobile phone as compared with previous clicking. The regression model is based on a large quantity of true historical clicking information and is acquired after the true historical clicking information is trained. The method has the advantages that whether cheat clicking of the advertising occurs or not is judged on the basis of multiple factors, and accordingly an analysis result is relatively accurate.

Method utilizing bus vehicle GPS data for evaluating road traffic condition dynamically

The invention relates to a method utilizing bus vehicle GPS data for evaluating road traffic condition dynamically and belongs to the field of intelligent traffic. Vehicle GPS data is recorded when a bus equipped with a GPS device is driving on a road, wherein the data includes vehicle location information and generated time information. When calculating, a GPS point in the data is converted to a space coordinate point and is matched to the road. GPS points in a specific range of the road are obtained in a timing period and then the GPS points are matched with bus stops with known location information. Invalid GPS points around the bus stops are removed. Then the valid GPS points are utilized for azimuth angle calculation. Through the comparison with a matched road azimuth angle, the driving direction of the bus is determined. Finally, according to the positions of the valid GPS points and the time information, the average driving speed of the vehicle is calculated and is modified to the a road traffic operation speed by utilizing a speed compensation model. Compared the road traffic operation speed with a traffic state section scale, the road traffic operation state is obtained.
