This application is a U.S. national phase application of International Application PCT/CN2016/095331, filed Aug. 15, 2016, which claims priority to and benefits of Chinese Patent Application Serial No. 201510641114.9, filed with the State Intellectual Property Office of P. R. China on Sep. 30, 2015, the entire contents of which are incorporated herein by reference.
The present disclosure relates to an internet technology field, and more particularly to an information push method and an electronic device.
Since Internet is more and more popular, network users are gradually increased, and on this basis, network advertisement is chosen by more and more companies. For network operators, this not only can greatly increase benefits, but also can provide users with a new manner for acquiring information.
It should be understood that during a process of pushing advertisements to the users through the Internet, there are always new advertisements provided by new companies and expired advertisements provided by old companies.
In practice, when the advertisements are pushed to the users by the network operators, advertisements to be pushed are determined not only according to the old advertisements provided by the old companies, but also according to new advertisements provided by the new companies. Commonly, different strategies are used in the above two conditions. Specifically, for the old advertisements, the advertisements to be pushed may be determined by historical push information of the old advertisements. However, for the new advertisements, the advertisements to be pushed are typically determined by randomly selecting from the new advertisements provided by the new companies since there is no or little historical push information related to the new advertisements.
The advertisements to be pushed may be determined from the new advertisements provided by the new companies as described above, thus accumulating the historical push information of the advertisements newly provided. However, the random selecting manner shows no consideration about the users' feelings, which may lead to bad user experience.

In embodiments of the present disclosure, a computer readable storage medium is provided, having stored therein instructions that, when executed by a processor of an electronic device, causes the electronic device to perform the information push method described above.
In order to more clearly illustrate the technical solutions in embodiments of the present disclosure, the drawings intended to be used in the embodiments are briefly described below. It will be apparent that the drawings in the following description are merely exemplary embodiments of the present invention. Those skilled in the art will be able to obtain additional drawings in accordance with these drawings without any inventive work.
Embodiments of the present disclosure will be described in details in the following descriptions, and it will be apparent that the described embodiments are only part of the embodiments of the present disclosure. All other embodiments which can be obtained by those skilled in the art without making any inventive work based on embodiments described in the present disclosure are within the scope of the present disclosure.
At step S101, a page view number of each piece of information in a predetermined information list for a predetermined period of time before a current time is acquired.
The predetermined information list is configured to store identifications of the information, such as advertisements, news, and weather reports, which are not limited in the present disclosure.
The predetermined period of time may be a time period having a unit of hours, such as 12 hours and 6 hours, or a time period having a unit of days, such as 15 days and 20 days.
The page view number is a primary indicator to evaluate a network news channel or a website, or even online news, and it is one of the most commonly used indicators for evaluating data traffic of the website.
In the above step, there may be at least one of page view numbers corresponding to each piece of information. For example, the page view number of the information may be acquired daily, such that the information may have a plurality of the page view numbers in the predetermined period of time.
At step S102, information is selected from the predetermined information list according to the page view number.
In an embodiment of the present disclosure, the selected information is information not meeting a predetermined information displaying condition. Specifically, the predetermined information displaying condition may be an information display condition related to the page view number. For example, if the page view number of the information is smaller than a certain threshold, the information is the information to be selected.
It should be understood by one skilled in the art that, the page view number of a piece of information in the predetermined period of time is usually related to a previous one. However, the relationship between the above two page view numbers will be less related as a time interval between two periods of time in which the two numbers are acquired respectively. For example, an absolute value of a difference between page view numbers of today and yesterday of an advertisement may be smaller than an absolute value of a difference between the page view numbers of today and the day before yesterday of the advertisement. For the above reason, it may be determined whether a piece of information is the information to be selected according to the page view number.
For example, if a piece of information has never been displayed before, such information may be the information to be selected, or if a page view number of a piece of information is gradually increased from 0, such information may be the information to be selected, or if a page view number of a piece of information is gradually decreased, such information may not be the information to be selected.
At step S103, an information recommendation degree of the selected information is acquired.
Specifically, an information recommendation degree of a piece of information may be a popularity degree of the piece of information which is obtained by an operation and maintenance staff through questionnaires or other forms of investigations before the information is delivered. The popularity degree may also be predicted according to an information type and other historical data. The information recommendation degree may also be price information, for example, effective cost per mille (eCPM).
At step S104, information to be pushed is determined from the selected information according to the information recommendation degree.
Since the information recommendation degree may have an effect on the user experience or income of an operator, the information to be pushed is thus determined according to the information recommendation degree.
For example, if the information recommendation degree is the popularity degree, information with a higher popularity degree may be determined from the selected information to be the information to be pushed.
If the information recommendation degree is the price information, information with a higher price may be determined from the selected information to be the information to be pushed.
Alternatively, the information recommendation degree may be a combination of the popularity degree and the price information. The information to be pushed may be determined according to several factors.
At step S105, the information to be pushed is pushed.
In an embodiment of the present disclosure, when the page view number of each piece of information in a predetermined information list for a predetermined period of time before a current time is acquired, a page view number PVADi of any information ADi in a predetermined information list for a predetermined period of time before the current time may be acquired according to a formula of
PVADi=w1*PVADi_fl+ . . . +wn*PVADi_fn,
where PVADi_fl represents a page view number of the information ADi for a first day before the current time, w1 represents an attenuation coefficient corresponding to PVADi_fl, PVADi_fn represents a page view number of the information ADi for a nst day before the current time, wn represents an attenuation coefficient corresponding to PVADi_fn, the nst day before the current time is a day most far from the current time which is determined according to the predetermined period of time, and values from w1 to wn are decreased progressively according to a predetermined rule.
Specifically, if the predetermined period of time is 120 hours, n=120/24=5.
In an embodiment of the present disclosure, as shown in
At step S102A, the page view number is adjusted according to a predetermined formula.
The predetermined formula may specially be
P′ADj 1=(target_pv−PADj1)/target_pv.
Specifically, PADj1 represents a page view number of the information ADi, P′ADj 1 represents an adjusted page view number corresponding to PADj1, and target_pv represents a predetermined threshold of a page view number.
It should be understood that, if target_pv is smaller than or equal to PADj1, the page view number of the information ADi is high. On this basis, it can be generally determined that the information ADi is not the information to be selected. Otherwise, if target_pv is greater than PADj1, the page view number of the information ADi is not high, and thus it can be determined that the information ADi is the information to be selected.
At step S102B, information having a page view number greater than a first probability threshold and smaller than a second probability threshold is selected from the predetermined information list.
Alternatively, the first probability threshold may be 0 and the second probability threshold may be 1.
In an embodiment of the present disclosure, when the information to be pushed is determined in the selected information according to the information recommendation degree, the information recommendation degree may be adjusted according to a following formula, information to be pushed is determined from information having an adjusted information recommendation degree meeting a predetermined second information selecting condition of the selected information. The formula is as follows:
PADq2′=PADq2−Pmin)/(Pmax−Pmin)
where PADq2 represents an information recommendation degree of information ADq, P′ADq 2 represents an adjusted information recommendation degree corresponding to PADq2, Pmin represents a minimal information recommendation degree in the information recommendation degrees, and Pmax represents a maximal information recommendation degree in the information recommendation degrees.
As described above, a first information selecting condition may be selecting information having a page view number greater than a first probability threshold and smaller than and equal to a second probability threshold from the predetermined information list. A second information selecting condition may be the same as the first information selecting condition, moreover, the second information selecting condition may also be selecting information having a adjusted information recommendation degree greater than a third threshold from the selected information. The information selecting conditions are not limited in the present disclosure.
Specifically, when the information to be pushed is determined, the page view number of the information may also be considered besides the information recommendation degree of the information. In an alternative embodiment of the present disclosure, when the information to be pushed is determined from information having an adjusted information recommendation degree meeting a second information selecting condition of the selected information, information having an adjusted information recommendation degree greater than a first recommendation degree threshold and smaller than or equal to a second recommendation degree threshold may be first to be searched for from the selected information, and then a selecting weight of any found information is calculated according to a formula below, and information to be pushed is determined from information having a selecting weight meeting a predetermined third information selecting condition of the found information. The formula is as follows:
PADr=wr1*PADr1+wr2*PADr2,
where PADr represents a selecting weight of information ADr, PADr1 represents an adjusted page view number of information ADr, PADr2 represents an adjusted information recommendation degree of information ADr, wr1 and wr2 represent selecting weights of PADr1 and PADr2 respectively, and wr1+wr2=1.
Specifically, if wr1 is smaller than wr2, information having a high information recommendation degree is first to be pushed, for example, an advertisement having a high price is first to be pushed. If wr1 is greater than wr2, information having a high page view number is first to be pushed.
In an embodiment of the present disclosure, since the selecting weight of original information which meets the predetermined information displaying condition is normally calculated to be high, in order to reduce error and to better determine the information to be pushed, the selecting weight of any found information may be calculated and the information may be searched for again, according to a predetermined selecting weight threshold. For example, information having a selecting weight greater than the first selecting threshold and smaller than or equal to a second selecting threshold is searched for from the found information, and then subsequent steps for determining the information to be pushed may be performed.
In an embodiment of the present disclosure, the first selecting weight predetermined is 0 and the second selecting weight predetermined is 100.
Alternatively, information may have a low probability for being displayed due to an over small selecting weight of the information. In order to prevent such a case from happening, in practice, after the selecting weight of any information is calculated, it is determined whether the selecting weight is smaller than a third selecting weight threshold. If the selecting weight is smaller than the third selecting weight, the selecting weight is used as a predetermined third selecting weight. In an embodiment of the present disclosure, the predetermined third selecting weight is 20.
Alternatively, the first recommendation degree threshold is predetermined to be 0 and the second recommendation degree threshold is predetermined to be 1.
In an alternative embodiment of the present disclosure, when the information to be pushed is determined from information having the selecting weight meeting the predetermined third information selecting condition of the found information, a random number may be acquired according to a predetermined range and a predetermined random function, and the information to be pushed is determined from the information having the selecting weight meeting the predetermined third information selecting condition of the found information according to the random number.
Specifically, a random number may be selected from a range of (0, 100] according to the random function, and information having the selecting weight greater than or equal to the random number is searched for and used as the information to be pushed.
According to embodiments of the present disclosure, after the page view number of each piece of information in the predetermined information list for the predetermined period of time before the current time is acquired, information is selected from the predetermined information list according to the page view number, the information recommendation degree of the selected information is acquired, information to be pushed is determined from the selected information according to the information recommendation degree, and the information to be pushed is pushed. Accordingly, information is pushed according to the information recommendation degree in embodiments of the present disclosure instead of a random selection manner, thus improving the user experience.
