DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0015] The earthquake information screening method provided by the embodiment of the present application comprises the following steps:

[0016] S100, acquiring a corresponding information list (I1, I2, …, In) based on an earthquake event in a preset geographical area; n n is the number of information, I i = (C i , F i , T i ), i is 1 to n; C i is the name of I i , is the jth presentation type of I i , m1 is the number of presentation types of I i , j is 1 to m1, is the kth presentation time period of I i , m2 is the number of presentation time periods of I i , k is 1 to m2.

[0017] In the embodiment of the present application, the information in the information list can be information related to the emergency treatment of the earthquake event, and the content of all information in the information list can be acquired through a corresponding information publishing platform and embodied in the event list in the form of a name. Preferably, in the embodiment of the present application, the information is earthquake emergency information.

[0018] In the embodiment of the present application, the presentation type is the form of displaying the specific content of the information, which can be determined based on the demand of the client, and in one example, can include a document, a picture, a table, a dynamic graph, etc. The presentation time period is the time period in which the information needs to be presented after the occurrence of the earthquake event, which can be determined based on the demand of the client, and in one illustrative embodiment, the presentation time period can include 0-2 hours, 2-4 hours, 4-8 hours, and more than 8 hours.

[0019] S200, sending collection information to the client, the collection information being used to instruct the client to input preference information about the information list, the preference information comprising preference information about the content of a certain information, preference information about the presentation of a certain information in a certain presentation type, and preference information about the presentation of a certain information in a certain presentation type and within a certain time period.

[0020] In the embodiment of the present application, the client is the demander of the information list of the earthquake event. In the specific implementation, the information list can be sent to each client through an information sending end. Each client can select the required information name, corresponding presentation type and presentation time period according to its own demand, and return the information list with the input preference information to the information sending end.

[0021] S300, based on the received preference information, obtain P(I i ), and Among them, PI i For preference I i The probability of the content; For preference I i Content and preferences The probability of presentation, For preference I i Content and preferences Presented and in The probability of presentation; For those who do not prefer I i The probability of the content, For those who do not prefer I i Content but preference The probability of presentation, For preference I i Content and preferences The remaining concentration preference presented is in The probability of presentation.

[0022] In this step, the information sender will obtain P(I) based on the preference information fed back by the client. i ), and Specifically, N is the number of clients, N1 is the preference I. i The number of clients who do not prefer I; N2 is the number of clients who do not prefer I. i The number of clients for the content. K1 represents the preference I among N1 clients. i by The number of clients presented; K2 represents the preference among N2 clients. The number of clients presented. L1 represents the preference I among K1 clients. i exist The number of clients presented; L2 represents the preference among N-K1 clients. The number of clients presented.

[0023] S400, based on P(I i ), Get I i First correction probability

[0024] In this step,

[0025] Thus, the first correction probability of each information can be obtained.

[0026] S500, based on and obtain the second correction probability I i

[0027] In this step, Thus, the second correction probability of each information can be obtained.

[0028] S600, obtain n second correction probabilities according to S500

[0029] S700, sort the n second correction probabilities in ascending order to obtain

[0030] S800, traverse A, if then a is a preset threshold.

[0031] In this step, if then it indicates that a turning point appears in and the preference degree of the client for the information after is not high, which can not be sent to the client. The value of a can be an experience value, which is used to ensure that the target information obtained can match the needs of the client as much as possible. In an illustrative embodiment, the value of a can be 0-0.05, and preferably can be 0.05.

[0032] Further, in this step, a coordinate system can also be drawn with the information quantity as the horizontal axis and the second correction probability as the vertical axis, and then the second correction probability curve is obtained based on A, and based on the drawn curve, the turning point of the curve is obtained.

[0033] Further, in the embodiment of the present application, the following steps can also be included:

[0034] S900, send the target information to the client according to the set presentation type.

[0035] Since the presentation type of the information list sent to the client is preset, in order to improve the information sending efficiency and ensure the information uniformity, after the target information is determined, only the information needed is retained and sent to the client according to the set presentation type.

[0036] ​​Further, in the embodiment of the present application, the target information is stored in the database, so that the target information corresponding to each historical earthquake event is stored in the database. When the same earthquake event occurs again in the preset geographical area, the target information is re-screened based on the last target information by using the earthquake information screening method of the present application, so that the target information more matched with the requirement of the client is obtained.
