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 by 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 pushing text information according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S110: and determining a target electronic book corresponding to the reading user.
Wherein, the target electronic book corresponding to the reading user is usually the book of interest to the user. The target electronic book may be determined in various ways. For example, the books that the user has read, the books that have been collected, the books that have been downloaded, etc. may be determined according to the historical reading data of the user, so as to determine the target electronic books corresponding to the reading user in combination with the types of the books that have been read, the books that have been collected, and the books that have been downloaded. In summary, the approach aims to mine books that may be of interest to the user, thereby regarding the books that are of interest to the user as target e-books.
In addition, the electronic book which is currently read by the reading user can be determined as the target electronic book, so that the text information associated with the electronic book is pushed to the user in the process of reading the current electronic book by the user, and the purpose of extended reading is further achieved.
In short, the present invention does not limit the specific determination manner of the target electronic book, as long as the target electronic book can be matched with the reading behavior of the user. In addition, the number of the target electronic books may be one or more, and the number of the target electronic books is not limited in the present invention.
Step S120: and acquiring a book tag vector of the target electronic book and a text tag vector of each text message.
The target electronic book corresponds to one book tag vector, the book tag vector is used for reflecting content characteristics of the target electronic book, and the book tag vector corresponding to the target electronic book can be determined in various ways such as a document theme generation model, a word embedding algorithm, or a word correlation algorithm.
In specific implementation, for a target electronic book, book content of the target electronic book is acquired, and the book content is subjected to vectorization expression, so that a corresponding book tag vector is generated. In addition, optionally, in consideration of a longer book content of the target electronic book, in order to improve processing efficiency, a preset chapter may be extracted from the book content of the target electronic book in advance, and a book tag vector may be generated according to the extracted preset chapter. The preset chapter can be determined in various ways. For example, in an alternative manner, considering that the amount of information of the initial part of the general electronic book is large, important contents such as a story background and the like are generally described collectively, and therefore, the preset chapters are the first N chapters of the electronic book; alternatively, considering that the end portion of the electronic book is generally more attractive to the user, the preset chapters may also be the last M chapters of the electronic book, where N, M is a natural number. In addition, in order to enable the preset chapters to reflect more important contents and highlights of the electronic book, in another alternative manner, word frequency information of each entity noun included in the electronic book may be counted through a word frequency statistical manner, and then chapters with more entity nouns including people, places, events and the like are selected as the preset chapters. Or, a chapter with a higher user interaction frequency may be extracted as a preset chapter according to user interaction data corresponding to the target electronic book, where the user interaction data includes: note-like interactive data, comment-like interactive data, idea-like interactive data, and the like.
In addition, one text message corresponds to one text tag vector, the text tag vector is used for reflecting content characteristics of the text message, and the text tag vector can be generated in various ways such as a document theme generation model, a word embedding algorithm, or a word correlation algorithm, similar to the generation way of the book tag vector.
The text information may be various text paragraphs or sentences. For example, the text information may be short text contents included in the target electronic book, or may be various types of short text contents other than the target electronic book, such as a highlight paragraph in a celebrity book or a partial paragraph in a periodical magazine, and the specific content of the text information is not limited by the present invention.
Step S130: and determining text preference indexes corresponding to the text information by the reading user according to the similarity between the text label vector of the text information and the book label vector of the target electronic book.
Because the text tag vectors and the book tag vectors are generated in a similar manner, the similarity between the text tag vectors of the text information and the book tag vectors of the target electronic book can be determined in a vector calculation manner, and the similarity can reflect the similarity between the text information and the target electronic book. Accordingly, according to the similarity between each text message and the target electronic book, the text preference index corresponding to each text message of the reading user is determined.
When there is one target electronic book, the text preference index is proportional to the similarity between the text information and the target electronic book, that is: the greater the similarity between the text information and the target electronic book, the higher the text preference index of the text information. When a plurality of target electronic books are available, the text preference index is further determined in a weighting manner by combining the weight of each target electronic book, wherein the weight of each target electronic book can be determined according to the preference degree of the user for the target electronic book.
Step S140: and screening a preset number of text messages according to the text preference indexes corresponding to the text messages of the reading user, and pushing the text messages to the reading user.
Specifically, the text messages are sorted from high to low according to the text preference index, so that a plurality of text messages with the top sorting are screened and pushed to the reading user to be displayed by the terminal device corresponding to the reading user.
Therefore, the method can determine the text preference index of the reading user corresponding to each text message according to the book tag vector of the target electronic book and the similarity between the text tag vectors of each text message, and convert the similarity comparison problem between the electronic book and the text message into the comparison problem between the tag vectors, so that the text message to be pushed can be screened according to the similarity between the text message and the target electronic book. The method can push the text information according to the reading preference of the user when the user reads the electronic book, so that the pushed text information is matched with the reading preference of the user, and the pushing accuracy is improved.
Example two
Fig. 2 shows a flowchart of a method for pushing text information according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
step S210: and determining a target electronic book corresponding to the reading user according to the historical reading data of the reading user.
Specifically, according to the historical reading data of the reading user, the reading preference of the reading user is mined, so that the electronic book matched with the reading preference is determined as the target electronic book.
Firstly, an interactive book list corresponding to a reading user is determined according to historical reading data corresponding to the reading user. The interactive book list is used for storing books with interactive behaviors with the reading user. Wherein the interaction behavior comprises at least one of: browse, download, read, and collect.
Then, for each electronic book in the interactive book list, screening a plurality of electronic books from the interactive book list as target electronic books according to the interactive duration, interactive sections and/or interactive types of the reading user for the electronic book. The electronic books with longer time length can be selected according to the interaction duration, the electronic books with more reading chapters can be selected according to the interaction chapters, and the electronic books with preset interaction types (such as reading or collecting) can be selected according to the interaction types. In addition, the interaction duration, the interaction sections and the interaction types respectively belong to different interaction dimensions, and accordingly, corresponding interaction weights can be set in advance for the interaction dimensions, and the target electronic book is screened according to the weighting results of the interaction dimensions.
It can be seen that the role of filtering the target e-books is to determine the books that are of interest to the user. In specific implementation, the interactive book list corresponding to each user can be established in advance according to historical reading books of each reading user. Then, for each electronic book in the interactive book list, determining a book preference index of each electronic book according to a weighting result of each interactive dimension, and screening a preset number of target electronic books according to the order from high to low of the book preference index.
Step S220: and acquiring a book tag vector of the target electronic book and a text tag vector of each text message.
The book label vector and the text label vector can be realized in various ways, and the purpose is to vectorize and express books or texts so as to facilitate comparison. The book tag vector and the text tag vector may also be referred to as a non-dominant tag vector or a recessive tag vector, where the contents belong to non-dominant contents.
In an implementation manner of this embodiment, a theme vector corresponding to a target electronic book is generated through a document theme generation model, and the theme vector of the target electronic book is used as a book tag vector of the target electronic book; and generating a theme vector corresponding to each text message through the document theme generation model, and taking the theme vector of each text message as a text label vector of the text message. The document theme generation model is an lda (latent Dirichlet allocation) model, and includes three-layer structures of words, themes, and documents. Specifically, the LDA model may generate the topic vector by the following process: firstly, extracting a theme from theme distribution for each electronic book; then, extracting a word from the word distribution corresponding to the extracted subject; and finally, repeating the process until each word in the electronic book is traversed. Each document in the corpus corresponds to one multinomial distribution of multiple topics. Each topic, in turn, corresponds to a multinomial distribution of a plurality of words in the vocabulary. Through the method, the theme vectors of the electronic books and the text information can be generated.
In another implementation manner of this embodiment, a word embedding vector corresponding to a target electronic book is generated by a word embedding algorithm, and the word embedding vector of the target electronic book is used as a book tag vector of the target electronic book; and generating word embedding vectors corresponding to the text messages by a word embedding algorithm, and taking the word embedding vector of each text message as a text label vector of the text message. In summary, the person skilled in the art can determine the book tag vector and the text tag vector in various ways as long as the vectorized representation of the text content can be realized.
Step S230: and determining the similarity between the text label vector of each text message and the book label vector of the target electronic book.
In the present embodiment, the target electronic books are plural, and therefore, the similarity between the text tag vector of each text information and the book tag vector of each target electronic book is determined respectively. Specifically, for each piece of text information, the similarity between the text label vector of the text information and the book label vector of each target electronic book is calculated one by one, so as to obtain a similarity score between the text information and each target electronic book. Or respectively calculating the similarity between the book tag vector of the target electronic book and the text tag vector of each text message one by one aiming at each target electronic book, so as to obtain the similarity score between the target electronic book and each text message.
Step S240: and determining text preference indexes corresponding to the text information by the reading user according to the similarity between the text label vector of the text information and the book label vector of the target electronic book.
Since there are a plurality of target electronic books in this embodiment, it is necessary to further determine in combination with the book preference index of each target electronic book. Specifically, book preference indexes of the reading user corresponding to the target electronic books are respectively determined, and text preference indexes of the reading user corresponding to the text information are determined by combining the book preference indexes of the reading user corresponding to the target electronic books. Wherein, the book preference index of the reading user corresponding to each target electronic book can be determined by the following modes: and respectively determining the interaction duration, the interaction section and/or the interaction type of the reading user for each target electronic book, and determining the book preference index of the target electronic book according to the interaction duration, the interaction section and/or the interaction type. Specifically, the interaction duration, the interaction sections and the interaction types respectively correspond to different interaction dimensions, corresponding interaction weights can be set for the interaction dimensions respectively, and accordingly, book preference indexes of the target electronic book are determined according to weighting results of the interaction dimensions.
In specific implementation, the text preference index corresponding to each text message of the reading user is determined by the following method:
firstly, determining similar text information sets corresponding to target electronic books; each similar text information set is used for storing a plurality of text information with the similarity between the text information set and the corresponding target electronic book larger than a preset threshold value. For example, in the present embodiment, a similar text information set corresponding to each electronic book in an electronic book database and a similarity score between each text information in the similar text information set and the electronic book may be determined in advance for each electronic book in the electronic book database, and the similar text information set corresponding to each electronic book and the similarity score between each text information in the similar text information set and the electronic book may be stored in a preset database. In specific implementation, the number of the text information included in each similar text information set may be preset, for example, 10, and accordingly, for each electronic book, the similarity score between each text information in the text database and the electronic book is respectively calculated, 10 text information are filtered according to the similarity score from high to low and added to the similar text information set corresponding to the electronic book, and the similarity score between each text information and the electronic book is correspondingly stored.
Then, aiming at each piece of text information contained in the similar text information set corresponding to each target electronic book, determining each target electronic book corresponding to each similar text information set containing the text information as the similar target electronic book corresponding to the text information; and determining a text preference index corresponding to the text information by the reading user according to the similarity between the text information and each similar target electronic book and the book preference index of each similar target electronic book.
For example, if there are 5 target electronic books and each set of similar text information of the target electronic books includes 10 text information, there are 50 text information available for pushing. In practical situations, since the same text message may appear in similar text message sets of different electronic books, the 50 text messages available for push may include multiple repeated text messages, and the number of text messages available for push obtained after deduplication is necessarily less than 50. Correspondingly, for each text information available for pushing obtained after the deduplication, each similar text information set containing the text information is determined first, and each target electronic book corresponding to each similar text information set containing the text information is determined as a similar target electronic book corresponding to the text information. Assuming that the text information available for pushing appears in the set of similar text information corresponding to the 3 target electronic books in total, the number of the similar target electronic books of the text information available for pushing is 3. And determining a text preference index corresponding to the text information by the reading user according to the similarity between the text information available for pushing and the 3 similar target electronic books and the book preference index of each similar target electronic book. For example, the similarity between the text information available for pushing and 3 similar target electronic books is s1, s2, s3, respectively, and the book preference index of each similar target electronic book is i1, i2, i3, respectively, then the text preference index corresponding to the text information by the reading user is calculated by the following formula: s1 × i1+ s2 × i2+ s3 × i 3. Therefore, the text preference index corresponding to the text information of the reading user is determined according to the accumulation result between the similarity score between the text information and each similar target electronic book and the book preference index of each similar target electronic book. The principle of the above mode is as follows: if a user is interested in an electronic book, the user is often also interested in textual information similar to the electronic book.
Step S250: and screening a preset number of text messages according to the text preference indexes corresponding to the text messages of the reading user, and pushing the text messages to the reading user.
Specifically, a preset number of text messages are screened from the text preference indexes from high to low and pushed to the reading user so as to be displayed by the corresponding terminal equipment. When the method is specifically implemented, the screened text information can be further sorted according to the text preference index, and the sorting serial numbers of the text information are provided for the reading user together for determining the display sequence.
Therefore, by the method in the embodiment, the preference index of unknown text information can be determined according to the electronic book with the known preference index, so that the pushing of the text information is more in line with the actual service requirement of a user. In addition, the present embodiment generates, for each electronic book, a tag vector uniquely corresponding to the electronic book, where the tag vector is a recessive tag vector used for calculating similarity, and the recessive tag vector has the following advantages compared with a conventional dominant tag vector:
the inventor finds that, in the process of implementing the invention, because the number of electronic books in the electronic book database is large, if a conventional dominant tag mining mode is adopted, a large number of dominant tags are mined, and each dominant tag and each electronic book are often crossed: for example, for a given overt tag, the given display tag is typically present in a plurality of different electronic books; moreover, for a given electronic book, there are often a plurality of corresponding dominant tags. Therefore, the dominant tags obtained by the conventional dominant tag mining method do not have one-to-one correspondence with the electronic book, and therefore, the method cannot be obviously used for accurately determining the similarity between the electronic book and the text information. In order to solve the problems, a tag vector which is uniquely corresponding to each electronic book is generated for each electronic book by using a hidden tag generation mode, so that the similarity problem between the electronic book and the text information is converted into the similarity problem between two tag vectors, the text information which is interested by a user is conveniently pushed according to the preference index of the electronic book, and the personalized requirement of the user is met. In addition, because the reading time of the electronic book is long and the number of reading users is large, the preference index of the electronic book is convenient to determine, and the text information is generally short and scattered, so that the preference index is inconvenient to directly determine, and accordingly, the preference index of the text information which is inconvenient to determine can be indirectly obtained through the preference index of the electronic book which is convenient to determine.
In addition, the text information specifically includes: articles, short content, and/or text segments contained in an electronic book. Therefore, the text information to be pushed can be a part of paragraphs in the electronic book, or paragraphs in the contents of web articles or other sources, and the specific form of the text information is not limited by the invention.
In addition, the embodiment is mainly used for pushing a plurality of text messages when the user opens the electronic book application, so as to realize the extended reading of the user. Accordingly, the present embodiment may be triggered when a user login instruction or an ebook application start instruction is detected. Alternatively, the method may also be triggered when a text push request triggered by a user for a text push portal included in the electronic book interface is detected.
In other embodiments of the present invention, a push operation of text information may also be triggered during a process of reading a current electronic book by a user, so that the user can browse extended information associated with the current electronic book. Correspondingly, when the target electronic book corresponding to the reading user is determined in the above steps, the electronic book currently read by the user is directly determined as the target electronic book, that is, the electronic book currently read by the user can be pushed in an associated manner.
In addition, in other embodiments of the present invention, the user characteristics of the reading user may also be determined according to the user portrait data, and accordingly, historical reading data of a same-type user group having similar characteristics to the reading user is obtained, so as to determine the target electronic book by combining the historical reading data of the same-type user group, which is not limited in this invention.
In summary, the present invention is not limited to specific application scenarios, and those skilled in the art can make various modifications and variations to the above-described embodiments.
In summary, by the method in this embodiment, the text preference index corresponding to each text information of the reading user can be determined according to the book tag vector of the target electronic book and the similarity between the text tag vectors of each text information, and the similarity comparison problem between the electronic book and the text information is converted into the comparison problem between the tag vectors, so that the text information to be pushed can be screened according to the similarity between the text information and the target electronic book. The method can push the text information according to the reading preference of the user when reading the electronic book, so that the pushed text information is matched with the reading preference of the user, and the pushing accuracy is improved.
