Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The method for acquiring the extended content provided by the embodiment of the present invention, as shown in fig. 1, includes steps 101-103:
step 101: the method comprises the steps of obtaining an extension request which is submitted by a first user and points to first target information, wherein the extension request comprises a first user identification of the first user and a first information code of the first target information, and the first target information is one item of information of a minimum unit in a current information set.
In the embodiment of the invention, the current information set can be a set of learning materials, and can also be other materials or information in a packaging form, such as a recruitment resume of an interviewer. If the current information set is the learning material, the current information set comprises course learning material and examination material, the learning material can be divided according to chapter sections and the like, and the minimum unit of the learning material is determined by a dividing mode; for example, if the learning material is divided into paragraphs, the content of each paragraph is an item of information. The examination data comprises subjective question information and objective question information; the subjective question information comprises a selection question and/or a judgment question, and the objective question information comprises one or more of a blank filling question, a short answer question, a discussion question, a resolution question and a case analysis question. For the examination data, the minimum unit of the examination data is one question (e.g. one choice question), and the target information corresponds to one question. Meanwhile, each target information is correspondingly provided with a unique information code, the information code can be generated by the target information or can be composed of random numbers or characters, and only one-to-one correspondence relationship exists between the target information and the information code. Or, if the current information set is a resume, the minimum unit is a resume, and the corresponding extended content may be a contact in the resume, that is, only after the extended content is obtained, the interview notification may be sent to the interviewer.
The first user is a user needing to obtain the extended content, each user corresponds to a unique user identifier, and the user identifier may be a mobile phone number, a mailbox, a login account number, an identity card number, or a generated unique character string of the user, which is not limited in this application. The first user may specifically send an extension request by using a client (such as an intelligent terminal, a tablet computer, a browser, and the like) used by the first user, and when the extension request sent by the first user based on the client is obtained, which extension content the user needs to obtain, that is, the extension content corresponding to the first target information, may be determined according to an information code (that is, a first information code) in the extension request. In the actual operation process, the user only needs to perform the operation of clicking the first target information, and the client automatically acquires the first user identifier and the first information code and generates a corresponding extension request. In the embodiment of the present invention, the first information codes are used to identify corresponding first target information, and the first target information and the first information codes are in one-to-one correspondence.
Step 102: and sending a resource acquisition request to the first user, and indicating the first user to submit corresponding resource data.
In the embodiment of the invention, after an extension request submitted by a first user is acquired, a resource acquisition request is sent to the first user, wherein the resource acquisition request is used for acquiring resource data of the first user; the first user can know that the corresponding resource data needs to be submitted by sending a resource acquisition request to the client logged in by the first user. The resource data is a resource or data, such as money or equivalent, which is agreed in advance by both parties (the first user and the execution subject executing the method), and the resource data may be a virtual integral or the like.
Step 103: after resource data which are submitted by a first user and point to first target information are obtained, first extended content corresponding to the first target information is fed back to the first user.
In the embodiment of the invention, the target information is divided according to the minimum unit, and correspondingly, the extension content is divided according to the minimum unit, so that a user can conveniently select the extension content required by the user. After the resource data submitted by the first user is acquired, the minimum unit of the extended content, that is, the first extended content corresponding to the first target information, can be fed back to the first user. In the embodiment of the present invention, the first extended content is obtained by extending the first target information on the basis of the first target information, so that the first user can conveniently obtain more related content with the first target information, or the first user can conveniently understand the first target information more deeply. Taking the first target information as the learning material as an example, the first extended content may be corresponding test question parsing, extended knowledge, or shorthand content for helping the user memorize the first target information. For example, the target information is "what treaty is the mortgage treaty of Qing government with the eleventh country in 1901? ", the correct answer is" clown treaty "; at this time, corresponding extended content may be set for the target information, where the extended content is a piece of shorthand content: "the stroke of the Xinchou two-character is 11, 1901 adds up to 11, and corresponds to 11 countries". That is, when the user sees the target information, the user can know the corresponding knowledge, but if the user needs to check the shorthand content, the user needs to submit the corresponding resource data to check the shorthand content, so that the conversion of the extended content into the resource data is effectively realized.
According to the method for acquiring the extended content, provided by the embodiment of the invention, the target information is divided according to the minimum unit, and the corresponding extended content is set, so that a user can conveniently select the required extended content; and after the resource data submitted by the user is acquired, the extended content is sent to the user side, so that the conversion between the extended content and the resource data is realized. Meanwhile, the minimum unit is used for feeding back the extended content, so that the user can more correctly judge whether the user needs the extended content, the user is promoted to purchase valuable extended content, and other people are further promoted to create more appropriate extended content, thereby forming virtuous circle.
On the basis of the above embodiment, referring to fig. 2, after "obtaining the extended request pointing to the first target information" submitted by the first user "in step 101, the method further includes step 1011:
step 1011: and judging whether the first user identification and the first information code have a binding relationship, and sending a resource acquisition request to the first user when the first user identification and the first information code do not have the binding relationship.
In the embodiment of the invention, the binding relationship between the user identification and the information code is used for indicating whether the corresponding user purchases the corresponding extended content or not, or indicating whether the user can obtain the corresponding extended content without submitting the resource data. Specifically, if the first user identifier and the first information code have a binding relationship, step 102 does not need to be executed, and the extended content of the first target information is directly sent to the user side; if the first user identifier does not have a binding relationship with the first information code, subsequent steps need to be executed, that is, a resource acquisition request needs to be sent to the first user.
Meanwhile, after acquiring the resource data pointing to the first target information submitted by the first user, the method further includes step 104:
step 104: and binding the first user identification and the first information code, and storing the binding relationship between the first user identification and the first information code.
In the embodiment of the invention, if the first user identifier does not have a binding relationship with the first information code, the first user is required to submit corresponding resource data, after the resource data is obtained, the first user is qualified for obtaining the extension content, the first user identifier and the first information code are bound, and the binding relationship between the first user identifier and the first information code is stored. When the first user continues to need to view the extended content of the first target information later, due to the existence of the binding relationship between the first user identifier and the first information code, the first user can normally view the corresponding extended content without submitting the resource data, and the first user is prevented from repeatedly submitting the resource data. Optionally, the storage of the binding relationship between the first user identifier and the first information code has a time limit requirement, for example, only the storage is performed for 1 year or 3 years, and the stored binding relationship is deleted after the time limit is reached, so as to avoid the phenomenon that the user uses the extended content for a long time and even illegally transfers the corresponding user account.
On the basis of the above embodiment, before step 101 "obtaining an extended request directed to first target information submitted by a first user", the method further comprises a login process, the login process comprising steps a1-a 2:
step A1: and receiving a login request submitted by a first user, wherein the login request comprises a first user identifier of the first user and a login device identifier of a login device.
Step A2: and judging whether the first user identification is associated with the login equipment identification, judging whether the number of the equipment identifications associated with the first user identification is smaller than a preset threshold value when the first user identification is not associated with the login equipment identification, and executing association operation of associating the first user identification with the login equipment identification when the number of the equipment identifications associated with the first user identification is smaller than the preset threshold value.
In the embodiment of the invention, in order to avoid the account sharing of multiple users, the user identification of the user is associated or bound with the logged-in equipment identification, and the upper limit of the associated quantity is set. Specifically, after receiving the login request, determining whether a first user identifier is associated with the device identifier, and if the first user identifier is associated with the device identifier, it indicates that the first user has logged in a corresponding user account by using the device, at this time, the login process is ended, and the subsequent step 101 and the like may be continued; if the first user identifier is not associated with the device identifier, it indicates that the first user is using a new device to log in the user account, and if the number of devices associated with the first user identifier is smaller than a preset threshold value, the first user is allowed to log in by using the new device, and the first user identifier and the login device identifier are associated at the same time. If the number of the devices which have been associated with the first user identifier exceeds the preset threshold, it indicates that the first user has associated with enough devices, at this time, the login may be prohibited, or the first user may be instructed to cancel the association state of a certain device which has been associated, and the new device replaces the device which has been associated previously. In the embodiment of the invention, the association relationship between the user identifier and the equipment identifier and the upper limit of the association quantity are set, so that the account number sharing of multiple users can be avoided, and the benefit of a party who creates the extension content is ensured.
On the basis of the above embodiment, before "obtaining the extended request pointing to the first target information" submitted by the first user in step 101, the method further includes a process of generating a summary, where the process specifically includes:
step B1: content summary information corresponding to first extended content of the first target information is generated in advance, and the content summary information is displayed in an associated display area corresponding to the first target information.
In the embodiment of the invention, the content abstract information of the first extended content is generated in advance and is displayed to the user, so that the user can conveniently judge whether the corresponding extended content needs to be checked according to the content abstract information. Specifically, the content summary information may be a keyword in the first extended content, or may be a category to which the first extended content belongs, such as shorthand content and analysis content.
On the basis of the above embodiment, the method further includes a process of generating the extension content, as shown in fig. 3, the process specifically includes steps 201 and 203:
step 201: and acquiring temporary extension content which is submitted by a second user and points to second target information, wherein the second target information is one item of information of the minimum unit in the current information set.
In the embodiment of the present invention, after a second user creates corresponding extended content for a user who creates the extended content, the extended content is uploaded to a corresponding system or server (an execution main body according to the present invention) as temporary extended content, and after acquiring the temporary extended content that is submitted by the second user and points to second target information, it is determined whether the temporary extended content is applicable to the second target information; specifically, whether the two are matched or not can be judged manually or automatically based on deep learning.
Step 202: and when the temporary expanded content is matched with the second target information, the temporary expanded content is taken as the second expanded content of the second target information.
In the embodiment of the present invention, when the temporary extended content matches the second target information, it is indicated that the temporary extended content is applicable to the second target information, and in this case, the temporary extended content may be used as the second extended content of the second target information. Here, the "second extended content having the temporary extended content as the second target information" may be a second extended content in which the extended content before the second target information is replaced with the temporary extended content, or the temporary extended content is added to a second extended content already existing before, and the extended content after the temporary extended content is added is used as the second target information.
Step 203: and after the resource data pointing to the second target information and submitted by a third user is obtained, the resource data pointing to the second target information is sent to the second user according to a preset proportion.
In the embodiment of the present invention, the third user is the same as the first user in nature and is the user who needs to obtain the extended content, and after the third user submits the resource data based on the steps similar to steps 101 and 102, a part of the resource data submitted by the third user can be allocated to the second user who creates the second extended content, so as to implement reasonable allocation of the resource data and further promote others to create the extended content.
On the basis of the above embodiment, after "obtaining the extension request pointing to the first target information" submitted by the first user "in step 101, the method further includes a process of recommending the extension content, where the process specifically includes steps C1-C6:
step C1: and determining a plurality of fourth users with the same user characteristics as the first user, wherein the user characteristics comprise one or more of friend relationship, user age bracket, user grade, geographic position, school to which the user belongs and user grade.
In the embodiment of the invention, no user is provided with user characteristics, and the user characteristics can be determined according to information filled by the user (such as a school to which the user belongs, a class to which the user belongs and the like) and also can be determined according to collected information (such as friend relationship, geographical position and the like); the friend relationship refers to whether the current user has friends among other users, for example, if the first user is in friend relationship with a certain user a, the user a can be used as a fourth user. The fourth user is determined through the same user characteristics, the range of the users can be preliminarily screened, the screened users have higher relevance with the first user, and the reliability of finally judging whether the extension content is recommended can be ensured.
Step C2: determining a current information set to which the first target information belongs, determining a first information matrix of the first user corresponding to the current information set, and respectively determining a second information matrix of the fourth user corresponding to the current information set; the first information matrix and the second information matrix are information matrices generated based on the same rule, each element in the information matrices corresponds to target information of a minimum unit, element values are used for representing information parameters of the corresponding target information, and the information parameters comprise target information which is not viewed by a user, target information which is viewed by the user but not extended content, target information and extended content which are viewed by the user, extended content recommended by the user or extended content not recommended by the user.
In the embodiment of the present invention, the target information of each minimum unit belongs to an information set (i.e. a current information set), that is, one element in the information set is the target information; each information set corresponds to an information matrix template, the initial value of each element in the information matrix template can be 0, and one target information corresponds to one element in the information matrix template; the information matrix template may be a one-dimensional matrix (i.e. the number of rows is 1 or the number of columns is 1), or the number of rows and columns may be determined according to the number of target information in the information set. For example, if a certain target information is a mathematical choice question belonging to a test question in a certain chapter of teaching, all test questions in the chapter can be used as a current information set; if the number of test questions is 10, the corresponding information matrix template may be a1 × 10 matrix, a2 × 5 matrix, or a 5 × 2 matrix, etc.
And meanwhile, updating element values in the information matrix template according to the operation of the user on the information set, thereby generating an information matrix corresponding to the user. Specifically, if the user has not viewed a certain target information, the corresponding element value in the information matrix may be 0; if the user has viewed the target information but not the extended content, the element value is 1; if the user has viewed the target information and the extended content, the element value is 2; if the user recommends the extended content (indicating that the user has viewed the target information and the extended content), the element value is 3; or the user does not recommend the extended content, the element value is-3. The larger the value of an element in the information matrix is, the greater the possibility that the current user corresponding to the information matrix views the extended content or recommends the extended content is.
The above "same rule" means that the first information matrix and the second information matrix are generated based on the same information matrix model, and the element value of each element in the information matrix is determined by the same setting, for example, the user has not viewed some target information, and the corresponding element value in the information matrix may be 0.
Step C3: respectively determining the similarity C (M1, M2) between the first information matrix M1 and each second information matrix M2, and selecting N second information matrices with the maximum similarity as effective matrices;
wherein the content of the first and second substances,
m1ijm2 is the value of the element in the ith row and the jth column of the first information matrix M1ijIs the element value of the ith row and the jth column in the second information matrix M2, M is the row number of the information matrix, and n is the column number of the information matrix.
In the embodiment of the invention, after the element values of all the elements in the two information matrixes are determined, the similarity between the two information matrixes can be determined. Specifically, the first information matrix and the second information matrix are both regarded as one-dimensional matrices, each information matrix corresponds to a vector of M × n dimensions, and at this time, the similarity in the above formula is actually a cosine value of an included angle between the two vectors, that is, C (M1, M2) ═ cos (M1, M2), at this time, the greater the similarity is, the smaller the included angle between the two vectors (corresponding to the first information matrix and the second information matrix) is, the smaller the difference between the two information matrices is, and the higher the similarity is. After the similarity between the first information matrix and all other second information matrices is determined, the first N second information matrices with the highest similarity can be selected as effective matrices for subsequent processing according to the size of the similarity.
Step C4: sequencing the N effective matrixes according to the sequence of similarity from small to large, determining a matrix sequence, and sequentially performing first updating operation on each effective matrix according to the matrix sequence, wherein the elements of the p-th effective matrix Ep after the first updating operation are as follows:
step C5: and performing second updating operation on the effective matrix after the first updating operation is performed according to the matrix sequence, wherein the elements of the q-th effective matrix Eq after the second updating operation are as follows:
in the embodiment of the invention, the effective matrixes are sorted firstly, the subsequent xth effective matrix refers to the sorted xth effective matrix, and the larger x is, the greater the similarity between the effective matrix and the first information matrix is; and then, the effective matrix with the maximum similarity is adjusted through two updating operations. Specifically, in the first update operation, each active matrix Ep updates the element values of the local active matrix Ep according to the element values of the previous p-1 matrices and the element values of the local active matrix Ep, that is:
where for the 1 st active matrix, p is 1, k is 1, and w is the time wk1, i.e. the 1 st active matrix is not changed in the first update operation. Meanwhile, the "performing the first update operation on each effective matrix in sequence according to the matrix sequence" in the embodiment of the present invention means performing the first update operation on the 1 st effective matrix, performing the first update operation on the 2 nd effective matrix (at this time, the 1 st effective matrix is already updated), performing the first update operation on the 3 rd effective matrix (at this time, the 1 st effective matrix and the 2 nd effective matrix are both updated matrices) … … until the nth effective matrix is performed with the first update operation, that is, p belongs to [1, N ],]。
further, the larger k is, the weight value wkThe larger the similarity is, the higher the weight value of the element in the effective matrix is, and the relevance between the updated effective matrix and the first user can be ensured as much as possible. Simultaneously:
i.e. the ownership weight value wkThe sum is 1, so that the updated element retains the characteristics of all the previous elements.
After the first updating operation is carried out on the N effective matrixes, second updating operation is carried out on the N effective matrixes in sequence; the difference between the second update operation and the first update operation is that: the first update operation is an update on the basis of the active matrices preceding the sequence, and the second update operation is an update on the basis of all active matrices, i.e. the elements of the qth active matrix Eq are:
Weight value w in second update operationlAnd the weight value w in the first updating operationkAre similar in nature, all wlThe sum is also 1. Similarly, performing the second update operation on the effective matrix according to the matrix sequence means: firstly, carrying out second updating operation on the 1 st effective matrix, wherein the referenced matrix elements are the elements for executing the first updating operation; performing a second update operation on the 2 nd effective matrix, wherein the matrix elements referred to by the 2 nd effective matrix are all elements performing the first update operation, and the elements of the 1 st effective matrix perform the first update operation and the second update operation; … … for the Nth effective matrix, the elements of other effective matrices referred to when it performs the second update operation are all performed with the first update operation and the second update operation, i.e. the elements in the Nth effective matrix after the second update operation have been performed the most, so that the association between the Nth effective matrix and other effective matrices is the strongest and most represents the association with the first user.
Step C6: determining the row number r and the column number c of the first target information in the information matrix, and determining the element value eN of the r row and the c column in the Nth effective matrix ENijNormalized value of brcAt a normalized value of brcRecommending the first extension content to the first user when the first extension content is larger than a preset threshold value;
wherein the content of the first and second substances,
in the embodiment of the invention, Sigmoid function is utilized

According to the method for acquiring the extended content, provided by the embodiment of the invention, the target information is divided according to the minimum unit, and the corresponding extended content is set, so that a user can conveniently select the required extended content; and after the resource data submitted by the user is acquired, the extended content is sent to the user side, so that the conversion between the extended content and the resource data is realized. Meanwhile, the minimum unit is used for feeding back the extended content, so that the user can more correctly judge whether the user needs the extended content, the user is promoted to purchase valuable extended content, and other people are further promoted to create more appropriate extended content, thereby forming virtuous circle.
