Abstract: A method, apparatus, device and storage medium for recommending information. The method includes determining, based on a set of feature representations of a plurality of features associated with information recommendation, a first set of weights indicating importance of the plurality of features. The method also includes determining a second set of weights based on the set of feature representations and the first set of weights. The method further includes recommending the information to a user based on the set of feature representations, the first set of weights and the second set of weights. The importance of respective features associated with the information recommendation can be accurately determined through this method, which further improves the effectiveness of information recommendation and improves the user experience.

Abstract: A method far verifying accuracy of RTK tilt compensation measurement is provided by the present invention. By firstly collecting the central coordinates and subsequently collecting the compensation measurement points, the offset and the height difference of the measurement points are calculated in real time, recorded and displayed. The maximum and minimum errors of the compensation measurement points near a point location are automatically counted, and whether an accuracy of the tilt compensation measurement of the RTK equipment meets the designed requirement of accuracy is verified. Therefore, the requirements for the operators are minimized. The method of the present invention can be used to detect the accuracy of the tilt compensation measurement of the RTK equipment.
