201results about How to "Reduce the probability of misjudgment" patented technology

The application discloses a method, device and system of recognizing spam information. The method includes the steps: extract the sender information in communication information; judge whether the sender of the communication information is the anticipated sender, and if not, recognize the communication information to be spam information, or go on recognizing the communication information. By judging whether the sender of the communication information is the anticipated sender, the application recognizes the spam information, which reduces the possibility of misjudging of the spam information, enhances the accuracy of the spam information recognition and strengthens the information filtering effect.

The embodiment of the invention provides an information object detection method and system. The method comprises the following steps that the information of a to-be-detected object is received by detection equipment, and the label of the to-be-detected object is carried by the information of the to-be-detected object; a credit value database is searched by the detection equipment according to the label of the to-be-detected object so as to obtain a credit value of the to-be-detected object; the credit value of the to-be-detected object is obtained through the comprehensive evaluation of the influence factors of the to-be-detected object in a specific time, and the influence factors refer to the behavior or the state of the to-be-detected object, which influences the security of the to-be-detected object; and the credit value of the to-be-detected object is compared with at least one preset credit value range by the detection equipment so as to obtain the first credit value range to which the credit value of the to-be-detected object belongs, and security detection is carried out on the information of the to-be-detected object according to a detection strategy corresponding to the first credit value range. Due to the adoption of the technical scheme, the detection performance can be improved and false judgment and leaked judgment probability can be lowered.

The invention discloses an information filtering method and device, and belongs to the technical field of computers and the Internet. The method includes the steps of obtaining target information sent by a target user; calculating the total amount of similar information sent by the target user within a preset time duration, wherein the similar information refers to information which has the whole information content the same as the target information or a part of keywords the same as the target information; detecting whether the total amount reaches a preset threshold value or not; filtering out the target information if yes. By means of the method and device, the problem that in the prior art, judgment omission still happens to some junk information is solved; junk information which is the same or similar and is repeatedly sent is filtered out, the judgment accuracy of junk information is improved, and the judgment omission rate is decreased.

The invention relates to a fault determination method based on redundancy inertial measurement information, wherein the redundancy is expressed by N which is not less than 3. The method comprises thefollowing steps of: (1) converting a pulse outputted by the current period of N paths of inertial measuring apparatuses to N paths of physical quantity information Txi, wherein i equals to 1, 2, untilN; (2) subtracting the physical quantity information Txi from Txj, and comparing the obtained difference value with a preset threshold sigma x; if the difference value exceeds the preset threshold sigma x, setting a mark delta theta ij to be 1, or the delta theta ij to be 0, wherein i equals to 1, 2, until N, j equals to 1, 2, until N, and j is not equal to i; (3) adding all the marks delta thetaij associated with the ith path to obtain FTxi, if the FTxi is more than or equal to a preset threshold M and not equal to the minimum value in the FTx1, FTx2, until FTxN, showing that the ith path of the physical quantity information TXi has an error, namely, the ith path of the inertial measuring apparatus has a fault; if not, regarding that the ith path of the inertial measuring apparatus hasno fault, wherein the preset threshold M ranges from 2 to N-1; and (4) waiting for an output pulse of the next period of the N paths of inertial measuring apparatuses, executing from the step (1) circularly.
