Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Example one

Fig. 1 shows a flowchart of a method for ordering recommendation of an electronic book and pushing book ordering according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:

step S110: and acquiring an interactive book list corresponding to an interactive period of the reading user.

The interaction period refers to a period of time defined by a starting time period and an ending time period, the user behavior is continuously monitored in the interaction period, and the interaction book list corresponding to the interaction period is obtained according to the monitoring result. The interactive book list is used for storing at least one electronic book interacted by the reading user in the interaction time period. Wherein, generating the interaction comprises: the user triggers various preset types of interactive operations such as clicking operation, searching operation, browsing operation and the like aiming at the electronic book, and the type and the number of the interactive operations can be flexibly set by technicians in the field according to service scenes.

Step S120: and determining the interaction depth value of the interaction book according to the interaction duration and/or the interaction type of the reading user corresponding to the interaction book aiming at the interaction book in the interaction book list.

Specifically, for each interactive book, the interaction duration and/or the interaction type of the reading user corresponding to the interactive book are determined. The interaction duration mainly refers to reading duration, and the longer the reading duration is, the larger the interaction depth value is. In addition, the interaction types include: different weights can be set in advance for different interaction types, and the interaction depth value of the interaction book is determined according to the weighting result of the interaction operation corresponding to each interaction type.

In summary, the interaction depth value of the interaction book is used to reflect the interaction degree of the reading user with respect to the interaction book: the larger the interaction depth value is, the deeper the interaction of the reading user on the interaction book is, namely: the greater the preference, the more interesting.

Step S130: and mapping the interactive depth value of the interactive book to an interactive weight value corresponding to the bucket-dividing interval according to a preset bucket-dividing mapping relation.

Specifically, a bucket mapping relationship is pre-established, and the bucket mapping relationship is used for mapping continuous interaction depth values which are inconvenient to compare into discrete interaction weight values which are convenient to compare. The sub-bucket mapping relation sets a plurality of sub-bucket intervals, and the numerical range of the interactive depth value corresponding to each sub-bucket interval and the interactive weight value corresponding to the sub-bucket interval.

Correspondingly, based on the bucket mapping relationship, the interaction depth value of the interaction book is converted into an interaction weight value corresponding to the bucket interval, so that comparison is performed on the interaction weight value in the subsequent steps.

Step S140: a plurality of training sample sets are constructed according to the interaction weight values of all interaction books in the interaction book list, a sequencing push model is trained through the training sample sets, and sequencing recommendation of the electronic books is carried out on the basis of the sequencing push model.

One training sample group may be a training sample pair including two interactive books, or may be a training sample list including a plurality of interactive books, which is not limited in this disclosure. In specific implementation, the training sample set is labeled according to a comparison result between interaction weight values of a plurality of training samples (i.e., the interaction books) in the training sample set. And training a sequencing pushing model based on the labeled training sample groups. The sequencing pushing model can be various models such as a neural network model, and the invention is not limited to this. When the electronic book is recommended through the sequencing push model, the difference of the interaction depth of the user on different electronic books can be fully considered, and therefore the accuracy of a recommendation result is improved.

Therefore, the training sample set can be constructed according to the interactive depth values of the interactive books, so that different sequencing recommendations can be carried out on the sequencing push model obtained through training according to different interactive depth values of the books, the influence of the interactive depth is considered in the sequencing recommendation process, and the sequencing result is more accurate. In addition, the interaction depth values which are inconvenient to compare can be converted into the interaction weight values which are convenient to compare in a bucket mapping mode, and therefore a plurality of training sample groups can be conveniently constructed.

Example two

Fig. 2 is a flowchart illustrating a method for recommending an electronic book by sorting according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:

step S210: and acquiring an interactive book list corresponding to an interactive period of the reading user.

Step S220: and determining the interaction depth value of the interaction book according to the interaction duration and/or the interaction type of the reading user corresponding to the interaction book aiming at the interaction book in the interaction book list.

Specifically, for each interactive book, the interaction duration and/or the interaction type of the reading user corresponding to the interactive book are determined. The interaction duration mainly refers to reading duration, and the longer the reading duration is, the larger the interaction depth value is. In addition, the interaction types include: different weights can be set in advance for different interaction types, and the interaction depth value of the interaction book is determined according to the weighting result of the interaction operation corresponding to each interaction type. In summary, the interaction depth value of the interaction book is used to reflect the interaction degree of the reading user with respect to the interaction book: the larger the interaction depth value is, the deeper the interaction of the reading user on the interaction book is, namely: the greater the preference, the more interesting.

In specific implementation, in order to ensure the comprehensiveness of the sample, the interactive book list needs to be continuously acquired for a plurality of reading users in a plurality of interactive periods. Therefore, in order to distinguish different reading users and different interaction periods, the list identifier of the interactive book list needs to include a user identifier, which may be a user ID of the reading user, and period information, which is identified by the start time point and the end time point. Therefore, each reading user as a sample at least contains one interactive book in the interactive book list in an interactive period. Then, for each interactive book contained in the interactive book list, the interactive duration and/or the interactive type generated by the user for the interactive book within the preset duration are monitored. The preset time duration can be three days or seven days, and since the reading time of a book is long, the preset time duration needs to be set to be slightly longer, and the interaction depth value corresponding to the interaction book by the user is determined by continuously monitoring the interaction time duration and the interaction type of each interaction behavior triggered by the user in the preset time duration for the interaction book. For example, the longer the interaction duration, the larger the interaction depth value; for another example, different weights may be set in advance for each type of interaction behavior, so that a weighting operation is performed on each interaction behavior according to an interaction type, and an interaction depth value is determined according to a weighting result, for example, the weights of the following interaction types decrease sequentially: a paid type interaction type, a download type, a bookcase adding type, a free chapter browsing type, and the like.

Step S230: and mapping the interactive depth value of the interactive book to an interactive weight value corresponding to the bucket-dividing interval according to a preset bucket-dividing mapping relation.

Specifically, a bucket mapping relationship is pre-established, and the bucket mapping relationship is used for mapping continuous interaction depth values which are inconvenient to compare into discrete interaction weight values which are convenient to compare. The sub-bucket mapping relation sets a plurality of sub-bucket intervals, and the numerical range of the interactive depth value corresponding to each sub-bucket interval and the interactive weight value corresponding to the sub-bucket interval. Correspondingly, based on the bucket mapping relationship, the interaction depth value of the interaction book is converted into an interaction weight value corresponding to the bucket interval, so that comparison is performed on the interaction weight value in the subsequent steps.

In specific implementation, the interaction weight value of the interaction book is determined in the following way: firstly, inquiring a preset barrel mapping relation, and determining a barrel interval corresponding to an interactive depth value of an interactive book. The sub-bucket mapping relation is used for setting a numerical range of the interactive depth value corresponding to each sub-bucket interval and an interactive weight value corresponding to each sub-bucket interval. And then, inquiring an interaction weight value corresponding to the sub-bucket interval corresponding to the interaction depth value of the interaction book, and taking the inquired interaction weight value as the interaction weight value of the interaction book. The interactive depth value is a continuous numerical value, and the interactive weight value is a discrete numerical value.

For example, if the reading user does not generate an interaction with respect to the book, the interaction depth value of the interaction book is 0 (specifically marked as a negative sample). When the reading user generates an interaction with respect to the book, the interaction depth value is a positive value (specifically marked as a positive sample), and the specific numerical value is determined according to the interaction duration and/or the interaction type. In specific implementation, 18 data sub-buckets may be set, each data sub-bucket corresponding to a different sub-bucket interval: the bucket interval of the first data bucket is (0-10), the interactive book whose interactive depth value belongs to the interval of (0-10) will fall into the first data bucket, and the interactive weight value corresponding to the first data bucket is 1, and the interactive weight value of the interactive book falling into the first data bucket is 1, the bucket interval of the second data bucket is (10-300), the interactive book whose interactive depth value belongs to the interval of (10-300) will fall into the second data bucket, and the interactive weight value corresponding to the second data bucket is 2, and the interactive book falling into the second data bucket has an interactive weight value of 2 … …, and the interactive weight value of the 18 th data bucket is 18, and the interactive book falling into the 18 th data bucket has an interactive weight value of 18, thus it can be seen that, through the data bucket dividing mode, continuous interaction depth values which are inconvenient to compare are converted into discrete interaction weight values which are convenient to compare.

By means of barrel mapping, the difference between the interaction depths can be better reflected. In the process of implementing the present invention, the inventor finds that, because the interaction depth value is usually determined according to the interaction duration, if the continuous interaction depth values are directly compared, differences between different books cannot be effectively mined. For example, assume that a book interacts for 299 minutes, the corresponding interaction depth value is 299; book two is interacted for 300 minutes, the corresponding interaction depth value is 300, if a training sample group is directly constructed according to the interaction depth value, the difference value of the interaction depth values between book two and book one is 1, but actually, the interaction depths of book one and book two belong to a barrel interval, and the significance of comparing the two is not great.

Step S240: and constructing a plurality of training sample groups according to the interaction weight values of all the interaction books in the interaction book list.

Specifically, each interactive book in the interactive book list is combined into a plurality of training sample groups according to the interactive weight value of each interactive book in the interactive book list, and each training sample group is labeled according to a comparison result between the interactive weight values of at least two training samples included in each training sample group. In specific implementation, a plurality of interactive books with different interactive weight values are determined as a training sample group, and the training sample group is labeled according to a comparison result between the interactive weight values of the plurality of interactive books in the training sample group.

The training sample set in this embodiment may be constructed in various ways, for example, the training sample set may be a training sample pair composed of two interactive book samples, or a training sample list composed of a plurality of interactive book samples, which is not limited in this disclosure.

Taking the training sample pairs as an example, when constructing the training sample pairs, the plurality of positive samples may be sorted according to the interaction weight values, and then each pair of positive samples obtained after sorting is combined to obtain the plurality of training sample pairs. Specifically, because the Pointwise algorithm is more suitable for processing samples with short interaction time, and the fitting performance of samples with long interaction time is not good, in this embodiment, the ranking recommendation model may be trained through the Pairwise algorithm and/or the Listwise algorithm, in order to better adapt to the above algorithm, a plurality of positive samples with interaction depth values greater than a preset depth threshold may be screened, and a training sample pair may be constructed according to the screened positive samples, so as to intensively learn the characteristics of samples with long interaction time. The difference in the interaction depth between samples can be expressed by the form of training sample pairs.

The inventor finds that if the interactive depth values of two books are directly compared, the comparison result cannot truly reflect the difference degree between the two books. For example, assuming that book in the first training sample set interacted for 290 minutes, the corresponding interaction depth value is 290; the book two is interacted for 300 minutes, the corresponding interaction depth value is 300, and if the first training sample group is directly constructed according to the interaction depth value, the difference value of the interaction depth values between the book two and the book one is 10; assuming that books in the second training sample group are interacted for 1 minute, and the corresponding interaction depth value is 1; and if the book four is interacted for 11 minutes, the corresponding interaction depth value is 11, and if the second training sample group is directly constructed according to the interaction depth value, the difference value of the interaction depth values between the book three and the book four is also 10. In the above manner, the difference between the first training sample set and the second training sample set is the same, but in the case of a long interaction time, the difference between the interaction depth of 290 minutes and the interaction depth of 300 minutes is not large; and in the case of a short interaction time, the interaction depth of 1 minute is more different from the interaction depth of 11 minutes. Therefore, when the training sample set is directly constructed by the interactive depth values, the degree of difference between the samples cannot be accurately reflected.

In order to solve the above problem, in this embodiment, a bucket mapping manner is used to map a continuous interaction depth value into a discrete interaction weight value, and after the bucket mapping process, the first book and the second book belong to the same bucket interval together, so that the interaction weight values of the first book and the second book are equal to each other, and at this time, the first book and the second book do not need to be constructed into a training sample group. Therefore, after barrel mapping processing, the constructed training sample set can be ensured to reflect the difference among samples.

Step S250: training a sequencing pushing model through a plurality of training sample sets, and carrying out sequencing recommendation on the electronic book based on the sequencing pushing model.

Specifically, the training sample set is labeled according to a comparison result between interaction weight values of a plurality of training samples (i.e., the interaction books) in the training sample set. And training a sequencing pushing model based on the labeled training sample groups. In specific implementation, a plurality of training sample sets are trained through a ranking algorithm to obtain a ranking pushing model. Wherein, the sequencing algorithm comprises: a sample pair based ordering algorithm and/or a sample list based ordering algorithm.

The ranking push model in this embodiment may be a neural network model, and the neural network model includes a network layer and a full connection layer. Accordingly, the above-mentioned ranking algorithm is mainly used for training at the fully-connected layer.

In addition, the training sample group in this embodiment is mainly used for learning the ranking information between the samples based on the Pairwise algorithm and/or the Listwise algorithm, but in practical application, when the training sample pairs are sparse, the Pairwise algorithm and/or the Listwise algorithm are directly adopted, which may cause the problem of overfitting. In addition, through the pre-training process, the sample vectors and the sample weights corresponding to the training samples obtained in the network layer are obtained, and accordingly, in the fine tuning process, the sample vectors and the sample weights obtained in the pre-training process can be directly shared.

In addition, the inventor finds that the transfer relationship between books can effectively reflect the importance of the books in the process of implementing the invention, so that in an improved implementation manner, in the process of training the sequencing recommendation model, the transfer weight determined according to the transfer relationship between the interactive books is further used as a sample attribute feature of the interactive books, and the accuracy of the model is further improved.

Correspondingly, when a plurality of training sample sets are constructed according to the interaction weight values of the interaction books in the interaction book list, the method is further realized in the following mode: firstly, determining the transfer relationship among all interactive books in an interactive book list, and generating a book transfer graph corresponding to the interactive book list according to the transfer relationship among the interactive books; then, according to the book transfer graph, the transfer weight of each interactive book is calculated, and the transfer weight is used as the sample characteristic of the training sample corresponding to the interactive book. The book transition diagram is generated according to the reading behavior data of the user. The book transfer graph comprises a plurality of transfer nodes, and each transfer node corresponds to one interactive book. Because a user has a behavior of jumping from a first interactive book to a second interactive book in a reading process, a transfer relationship between transfer nodes is established based on a book jumping behavior (also called book transfer behavior) triggered by the user, wherein the transfer relationship includes: the direction of transfer, for example, into or out of.

Specifically, when the transfer relationship between each interactive book in the interactive book list is determined, and a book transfer graph corresponding to the interactive book list is generated according to the transfer relationship between the interactive books, the book transfer graph is generated by the following method: detecting whether a reading user interacts with a second interactive book or not in the process of reading the first interactive book aiming at the first interactive book in the interactive book list; if so, determining a second transfer node corresponding to the second interactive book as a transfer-out type transfer node of a first transfer node corresponding to the first interactive book; and determining a first transfer node corresponding to the first interactive book as a transfer class transfer node of a second transfer node corresponding to the second interactive book. The first interactive book may be any book in the interactive book list, and in a specific implementation, an interactive time period during which a reading user interacts with the first interactive book needs to be determined, where the interactive time period may be in units of hours or days, and the book belongs to a long-interaction business object, so the interactive time period lasts for a long time. Also, during this interaction period, the user may interact with other books incrementally. For example, in the process of reading the western notes, the user downloads the three kingdoms rehearsal or the water entermorphism for alternate reading. Correspondingly, the number of the second interactive books can be one or more, and all newly added interactive books are used as the second interactive books in the interactive time period of reading the first interactive books by the reading user. Therefore, the user turns to the second interactive book from the first interactive book in the reading process, so that the transfer node corresponding to the second interactive book is the transfer-out type transfer node for the first interactive book; for the second interactive book, the transfer node corresponding to the first interactive book is the transfer-in transfer node. For a transfer node corresponding to any interactive book, the transfer node may include both a plurality of transfer-in transfer nodes and a plurality of transfer-out transfer nodes.

Correspondingly, when the transfer weight of each interactive book is calculated according to the book transfer graph, a transfer node corresponding to any interactive book contained in the book transfer graph is used as a target transfer node, and a transfer-in type transfer node corresponding to the target transfer node and a transfer-out type transfer node corresponding to the target transfer node are determined; and calculating the transfer weight of the interactive book corresponding to the target transfer node according to the transfer-in type transfer node and the transfer-out type transfer node. In addition, the number of the transfer-out type transfer nodes of each transfer-in type transfer node and the transfer weight of the transfer-out type transfer node of each transfer-in type transfer node can be further determined respectively aiming at each transfer-in type transfer node corresponding to the target transfer node, and the transfer weight of the interactive book corresponding to the target transfer node can be calculated by combining the number of the transfer-out type transfer nodes of each transfer-in type transfer node and the transfer weight of the transfer-out type transfer node of each transfer-in type transfer node.

In specific implementation, the transfer weight of the interactive book corresponding to the target transfer node may be calculated according to a preset damping coefficient, the total number of transfer nodes included in the book transfer graph, the transfer weight of each transfer-in type transfer node corresponding to the target transfer node, and/or the transfer weight of each transfer-out type transfer node corresponding to the target transfer node. For example, the transfer weight of the interactive book corresponding to the target transfer node may be calculated according to a ratio between the sum of the transfer weights of the transfer-in transfer nodes corresponding to the target transfer node and the sum of the transfer weights of the transfer-out transfer nodes corresponding to the target transfer node. Of course, those skilled in the art can also flexibly set various ways to calculate the transfer weight of the interactive book corresponding to the target transfer node, and the specific calculation details are not limited in the present invention.

In an alternative implementation manner, the transfer weight pr (u) of the interactive book corresponding to the target transfer node u may be calculated by the following formula:

wherein d is a damping coefficient, and the specific numerical value can be flexibly set according to the actual condition. And N is the total number of the transfer nodes contained in the book transfer graph. In practical cases, N may be the total number of all the transfer nodes included in the book transfer graph, or may be the number of associated transfer nodes having a transfer-in or output relationship with the target transfer node. In the latter mode, the value of N is determined according to the number of associated transfer nodes corresponding to the target transfer node. Wherein associating the transfer node comprises: direct association transfer nodes and indirect association transfer nodes. Specifically, directly associating the transfer node means: a transfer-in class transfer node and a transfer-out class transfer node corresponding to the target transfer node; the indirect association of the transfer node means: a transfer-in class transfer node and/or a transfer-out class transfer node corresponding to a directly associated transfer node of the target transfer node.

Wherein V in the above formula represents any transfer node in the set Iu, the set Iu is used to store each transfer-in type transfer node corresponding to the target transfer node, pr (V) represents the transfer weight of the transfer node V, and | o (V) | represents the number of transfer-out type transfer nodes corresponding to the transfer node V. Through the formula, the transfer weight value of the interactive book corresponding to the target transfer node u can be calculated.

It should be further emphasized that the above-mentioned interactive book list may be a list corresponding to one reading user, or may be a list corresponding to a plurality of reading users, which is not limited in the present invention. Correspondingly, when the interactive book list is a list corresponding to a plurality of reading users, the book transfer diagram can reflect the transfer conditions of the users, so that the result is more in line with the requirements of most users.

In conclusion, the training sample set can be constructed according to the interaction depth values of the interaction books, so that different sequencing recommendations can be carried out on the sequencing push model obtained through training according to different interaction depth values of the books, the influence of the interaction depth is considered in the sequencing recommendation process, and the sequencing result is more accurate. In addition, the interaction depth values which are inconvenient to compare can be converted into the interaction weight values which are convenient to compare in a bucket mapping mode, and therefore a plurality of training sample groups can be conveniently constructed. In addition, in the embodiment, the transfer relationship among the books is further considered in the training process, so that the importance degree of the books is conveniently and accurately determined according to the transfer relationship among the books, and the sequencing result is more accurate.
