Description
Technical Field
The present invention relates to the field of information dissemination, and in particular, to a resource dissemination method, apparatus, server, and computer-readable storage medium.
Background
Most of current domestic and foreign popular network information propagation platforms are based on concern relationships, and resources published by resource publishers can be transmitted to concerns of the resource publishers. However, the information dissemination platform based on the concern relationship has the following disadvantages: 1. the hot resources are often repeated among different publishers, and the followers overlapping among the different publishers are easy to receive multiple highly similar resources, which seriously affects the resource receiving experience of the followers and is not beneficial to maintaining the relationship of the followers; 2. the resource publisher fakes on the number of the concerned persons for the benefit, and the large amount of zombie powder seriously affects the resource quality judgment of other users on the publisher; 3. publishers with weak information acquisition advantages often need strong innovation capability to maintain quality of newly published resources to maintain the concern relationship, when the frequency of examination on the innovation capability is increased or the time span is lengthened, most of the publishers cancel the concern relationship due to the reduction of the resource quality of the publishers, and when most of the publishers have a trend of reducing concern quantity, the user experience of the information propagation platform based on the concern relationship is seriously influenced.
In addition to the information dissemination platform based on the attention relationship, there is also a resource dissemination platform represented by "today's headline" that performs algorithm recommendation based on the user history reading preference. The resource propagation method for carrying out algorithm recommendation based on historical reading preference of a user has the following defects at present: 1. the collected data such as click rate, reading duration, reading integrity and the like do not represent the real intention of the user. In order to increase the recommendation rate by using an algorithm recommendation mechanism, many resource publishers write titles that do not conform to the content or publish exaggerated and strange content, which seriously affects the user experience. 2. Similar resources can be recommended repeatedly, and copying among publishers in different platforms, imitation among publishers in the platforms and recognition errors of historical reading preference can cause users in the platforms to receive similar resources repeatedly.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment:
referring to fig. 1, fig. 1 is a schematic flow chart of a resource propagation method according to a first embodiment of the present invention, which at least includes the following steps:
s101, acquiring a first resource propagated by a first account in a first user group.
In this embodiment, the first user group may be all users registered in a certain information dissemination platform, or may be users who focus on a specific plate or a specific circle of the information dissemination platform. For example, as shown in fig. 2, for the information dissemination platform a, it may include a plurality of pieces or circles, such as the sports pieces, the historical pieces, the military pieces, and the reading pieces shown in fig. 2, the sports pieces may be grouped into a ball maze, a track and field circle, a swimming circle, a racing boat circle, etc., and the ball maze may be further grouped downward into a football group, a basketball group, a badminton group, a tennis group, a ping-pong group, etc. The user automatically joins the user group of the information dissemination platform after registering on the information dissemination platform, and then the user can join the user group of the section, the circle or the group by paying attention to the section, the circle or the group. For example, after a user pays attention to a sports block, the user group joins the sports block. In this embodiment, after a user joins a user group, the user can perform resource dissemination in the user group, where the resource for dissemination includes, but is not limited to, information carriers such as text, picture, video, audio, and light program.
S102, obtaining the influence of the first account in a first user group, and determining the transmission amount of the first resource according to the influence.
In this embodiment, when receiving an instruction for the first account to propagate the first resource, the server may query, from the influence library, influence of the first account on the first user group, so as to determine the propagation amount of the first resource according to the influence. The transmission amount and the influence are in a positive correlation relationship, namely the larger the influence of the first account is, the larger the transmission amount is.
In this embodiment, the influence of the first account can be generated according to the historical behavior of the account, and can be obtained by the following method:
the first method comprises the following steps: and determining the influence of the first account according to the historical posting number of the first account.
And the second method comprises the following steps: and determining the influence of the first account according to the historical replying number of the first account.
And the third is that: and determining the influence of the first account according to the number of the postings which are historically returned by the first account.
And fourthly: and determining the influence of the first account according to the total propagation quantity of the resources historically propagated by the first account.
It should be noted that the present invention includes, but is not limited to, the above influence determination manner.
S103, acquiring a first resource propagation tree of the first resource; wherein the first resource propagation tree is used for recording and caching the propagation action of the first resource.
In this embodiment, when detecting an instruction for the first account to propagate the first resource, the server first queries whether a first resource propagation tree of the first resource exists at present, and if so, directly reads the first resource propagation tree. If the first account does not exist, the first account is the first-sending transmission account of the first resource, and the server takes the first resource as a root node and the first account as a child node of the root node to create a first resource transmission tree.
As shown in fig. 3, fig. 3 is a possible data structure manner of the first resource propagation tree, where a root node is the first resource, a first transmission account of the first resource is a sub-node of the root node, and a next-level sub-node of each sub-node represents a propagation direction of the resource. Through the first resource propagation tree, it is clear which user accounts have received the first resource and the whole propagation path of the first resource is known.
S104, determining a target user account for transmitting the first resource according to the first resource transmission tree, the user accounts which have not received the first resource in the first user group and the transmission amount, and recording the target user account into the first resource transmission tree.
As shown in fig. 4, in this embodiment, specifically, the server first adds a to-be-decimated sub-node corresponding to the propagation amount under the node of the first resource propagation tree corresponding to the first account, where the to-be-decimated sub-node stores the user group ID to which the parent node propagates an action; and then for each sub-node to be decimated, a user account not receiving the first resource is decimated from the user group stored in the sub-node to be decimated to be used as a target user account to replace the sub-node to be decimated.
S105, the first resource is spread to the target user account.
In this embodiment, after determining the target user accounts, the server propagates the first resource to the target user accounts, thereby completing the propagation of the resource.
In summary, in the resource propagation method provided by this embodiment, during propagation, the propagation amount is determined according to the influence of the account, so that the resources propagated by some accounts with smaller influence (such as vest accounts, inactive accounts, or newly registered accounts) are not widely propagated, and thus, propagation of some resources with lower quality (such as rumors or resources whose titles do not conform to the content) can be effectively limited. In addition, during the transmission, the resource is only transmitted to the user account which does not receive the first resource, so that the problem that the user account repeatedly receives similar or same resources is avoided, and the information receiving experience of the user is improved.
Second embodiment:
referring to fig. 5, fig. 5 is a flowchart illustrating a resource propagation method according to a second embodiment of the present invention.
The difference from the first embodiment is that after step S101, before step S102, the method further includes:
s2011, judging whether the first resource has an exception handling mark; if not, S102 is executed, and if yes, S2012 is executed.
S2012, judging whether the exception handling flag of the first resource is propagation termination; if so, stopping propagating the first resource; if not, executing S2013.
S2013, a hanger is called to temporarily store an instruction of the first account number for transmitting the first resource in the first user group through the influence, and exception handling feedback is waited; if the instruction returned by the exception handling feedback is a propagation stopping instruction, marking the exception handling state as propagation stopping, and feeding back an exception handling result to the user who receives the first resource; if the instruction returned by the exception handling feedback is an exception release instruction, the exception handling mark is deleted, the instruction temporarily stored by the hanger is released, and the step S102 is executed.
In this embodiment, when acquiring a first resource to be propagated by a first account, a server may first perform an exception check on the first resource, and determine whether an exception handling flag exists in the first resource. If the first resource does not exist, it indicates that the first resource is a normal or legal resource, and the server performs step S102 and subsequent steps to perform propagation of the first resource normally. Otherwise, the server determines the type of the exception handling flag, and stops propagating the first resource if the type of the exception handling flag is termination of propagation (e.g., a resource that has been identified as containing bad content, a rumor, etc.). If the first resource is the exception handling mark of other types (if the first resource is reported but not verified), the server calls a hanger to temporarily store an instruction of the first account number for transmitting the first resource in the first user group with the influence, and waits for exception handling feedback; if the instruction returned by the exception handling feedback is a propagation stopping instruction, marking the exception handling state as propagation stopping, and feeding back an exception handling result to the user who receives the first resource; and if the instruction returned by the exception handling feedback is an exception removing instruction, deleting the exception handling mark, and releasing the instruction temporarily stored by the hanger so as to normally propagate the first resource.
In the embodiment, before each resource is propagated, the abnormal detection is carried out on the resource, so that the propagation of the problem resources can be effectively limited at the propagation source, an information propagation platform is purified, and the wide propagation of the problem resources is avoided. In addition, because the propagation path of the resource is already recorded by the first resource propagation tree, the propagation source of the first resource can be known through the first resource propagation tree, and the relevant party can be found conveniently.
Third embodiment:
this embodiment is optimized for step S104 based on the first embodiment.
In this embodiment, step S104 specifically includes:
adding a sub-node to be decimated corresponding to the propagation quantity under the node of the first resource propagation tree corresponding to the first account; and the child node to be selected stores the user group ID pointed by the propagation action of the parent node.
And when the number of the user accounts which do not receive the first resource in the first user group is judged to be smaller than the broadcast quantity, acquiring an influence coefficient of the first user group crossing the second user group.
And determining the cross-group flux according to the influence coefficient, the propagation quantity and the number of user accounts which do not receive the first resource in the first user group.
Adding a corresponding number of sub-nodes to be selected under the created associated nodes according to the cross-group flux; the association node stores a first resource ID, a first user group ID, and a second user group ID, and is mounted under a root node of the first resource propagation tree.
And for each sub-node to be decimated, a user account not receiving the first resource is decimated from the user group stored in the sub-node to be decimated to be used as a target user account to replace the sub-node to be decimated.
In the embodiment of the present invention, preferably, if the number of the user accounts which do not receive the first resource in the first user group is smaller than the transmission amount, a sub node to be decimated corresponding to the number of the user accounts which do not receive the first resource is added to the node of the first resource transmission tree corresponding to the first account.
In this embodiment, if the propagation amount of the first account is greater than the number of the user accounts that do not receive the first resource in the first user group, cross-group propagation of the first resource needs to be considered.
For example, assuming that the transmission amount of the first account is 10, and the number of user accounts in the first user group that do not receive the first resource is 3, 7 transmission amounts (transmission margins) remain. At this time, the 7 propagation quantities may be used for group-crossing propagation, that is, propagation to a second user group, for example, from a sports block to a user group of the entire information propagation platform (upward group crossing), or from a sports block to a military block (level group crossing); or, from the tennis group level to the badminton group, the badminton level to the basketball group, the table tennis upward to the fan ring, etc., according to the cross-group historical performance, the cross-group influence coefficient (a real number greater than 0) of the net fans to the badminton fans may be larger, the cross-group influence coefficient of the badminton fans to the basketball fans is small, and the cross-group influence coefficient of the table tennis fans to the outside (level or father) may be small. In addition, the user groups can also carry out collective operation, for example, one information publishing target group is three pellets, a compound user group (badminton fan U tennis fan U ping-pong fan) can be produced, and the users can carry out resource propagation in the 3 user groups and carry out group-crossing propagation on the basis of the resource propagation. Preferably, the system defaults to upward cross-group, and cross-group propagation can also be performed according to a cross-group path (including a combination of upward cross-group and flat cross-group) set by the resource publisher, so that the information is effectively guaranteed to be propagated in the corresponding information preference group.
It should be noted that, when the server still fails to acquire the account that has not received the first resource within the preset time to replace the sub-node to be decimated, the program terminates the operation.
As shown in fig. 6, in the present embodiment, during group crossing, a group crossing flux is obtained by first calculating according to an influence coefficient and a propagation margin, and then a corresponding number of sub-nodes to be decimated and sub-nodes to be accumulated are added under the created association nodes according to the group crossing flux; the association node stores a first resource ID, a first user group ID and a second user group ID, and is mounted under a first resource propagation tree root node, the sub-node to be accumulated is used for accumulating each node of the fractional part of the cross-group flux, when the accumulated value is greater than or equal to 1, a sub-node to be selected is generated, and the part greater than 1 is retained in the sub-node to be accumulated.
In this embodiment, after all the sub-nodes to be decimated are determined, for each sub-node to be decimated, a user account not receiving the first resource is decimated from the user group to which the node value points as a target user account to replace the sub-node to be decimated.
It should be noted that, since the cross-group flux may not be an integer, there are three processing methods as follows:
first, rounding down the cross-group flux, for example, assuming a cross-group flux of 50.4, then rounding up to 50, i.e., adding 50 sub-nodes to be decimated under the associated node created.
Second, rounding up the cross-group flux, for example, assuming that the cross-group flux is 50.4, then rounding up is 51, i.e., 51 sub-nodes to be decimated are added under the created association node.
Third, a sub-node to be accumulated is set separately for the fractional part of the cross-group flux without rounding the cross-group flux. For example, assuming a cross-group fluence of 50.4, 50 sub-nodes to be decimated (each occupying 1 cross-group fluence) and one sub-node to be accumulated (occupying 0.4 cross-group fluences) are added under the created association node. And then, if other group cross fluxes which are not integers exist, the decimal part of the group cross fluxes is firstly superposed to the sub node to be accumulated, and when the decimal part is more than 1, a complete sub node to be selected and another updated sub node to be accumulated are generated.
It should be noted that the present invention defaults to handling cross-group flux in a third manner.
Fourth embodiment:
on the basis of the first embodiment, after step S105, the method further includes:
acquiring the operation of the target user account on the received first resource; wherein the operation comprises a first type selection and a second type selection; the first type selection triggers the first resource to be spread in a user group where the first resource is located according to the influence of the target user account; the second type of selection does not trigger the first resource to be propagated again.
In this embodiment, the first type of selection includes "approval", "forwarding", "support", "interest", etc. to trigger the selection propagation of the first resource, and the second type of selection includes "objection", "report", "dislike", "uninteresting", etc. to not trigger the selection propagation of the first resource propagation.
In this embodiment, the influence is updated in real time during the propagation of the first resource; the real-time influence is equal to the influence obtained by multiplying an adjusting coefficient by the obtained influence, the adjusting coefficient is in negative correlation with the adjusting coefficient according to the average number of the group members in a time period, and the positive correlation of the adjusting coefficient is calculated according to the proportion of the number of the first type selective accounts in the first resource transmission tree to the transmission quantity. In the embodiment of the present invention, after receiving the selection of the first resource by the user, the selection number of the user is recorded, the recording mode may be stored in a table form, or may be recorded in a node of a propagation tree, and the adjustment coefficient is updated according to the selection of the first resource by the user, for example, if more users make the first type selection, the adjustment coefficient is multiplied by a number greater than 1, and if more users make the second type selection, the adjustment coefficient is multiplied by a number less than 1. If more users make the second type of selection, the adjustment coefficient is affected, so that the influence of the first account is affected, and the server checks the first resource to determine whether the first resource includes bad or illegal content.
In the embodiment of the present invention, if the number of times of a second type of selection (such as reporting and complaint) received by a first resource and indicating a resource abnormality reaches a preset threshold, an abnormality processing flag action is triggered, a server adds an abnormality processing flag to the first resource, the server checks the first resource, if the server detects that the first resource is not abnormal (such as illegal or illegal), the server returns an hanger abnormality removing instruction, if the server detects that the first resource includes bad or illegal contents, the server returns a hanger end propagation instruction, the server adds a hanger end propagation flag to the first resource and sends flag information to a source user uploading the first resource, if the source user of the first resource makes a complaint, the server performs a second check on the first resource, and if it is determined that the first resource has no problem, the server returns a hanger abnormality removing instruction, otherwise, the first resource continues to maintain the abnormal marking state, so that when other accounts transmit the first resource, the abnormal processing mark is detected, and the transmission of the first resource is suspended, thereby preventing the diffusion of bad or illegal contents.
It should be noted that, in the embodiment of the present invention, the triggering and the releasing of the exception handling flag may occur multiple times. That is, after the exception handling flag of the first resource is removed, if the number of times of receiving the second type selection indicating the resource exception again reaches the threshold, the server is still triggered to execute the exception handling flag and the subsequent checking process. The threshold value may be kept constant, or may gradually increase with the number of triggers, and the present invention is not limited in particular.
