Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The information recommendation method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. In one embodiment, a computer device is provided, which may be a server, the internal structure of which may be as shown in FIG. 1. The computer device includes a processor, a memory, and a network interface connected by a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, computer programs, and a database. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage media. The database of the computer device is used for storing relevant data for information recommendation. The network interface of the computer device is used for communicating with an external terminal through a network connection. The computer program is executed by a processor to implement an information recommendation method.
In one embodiment, as shown in fig. 2, an information recommendation method is provided, and the method is applied to the computer device in fig. 1 for illustration, and includes the following steps:
S201, acquiring the current query characteristics of the current query statement input by the target user.
The target user may be a user who has information recommendation requirements. The current query statement may be a statement entered by the target user on the information recommendation platform that describes the query requirements of the target user. The current query feature may be a feature word representing the current query statement, or may be a feature vector generated based on the feature word.
Optionally, in this embodiment, when the target user inputs the current query sentence on the information recommendation platform (for example, a learning-reserved information consultation platform developed by a financial institution), the computer device may acquire the current query sentence input by the target user, extract a keyword from the current query sentence, and use the keyword as the current query feature of the current query sentence. Another implementation manner may be that after the computer device obtains the current query sentence input by the target user and extracts the keyword, a vector value is given to the keyword in the current query sentence according to the predetermined keyword feature vector, and the current query feature of the target user is obtained after the fusion processing of the vector values.
The manner of performing the fusion processing on each vector value may include: the vectors are subjected to a summation process, and the vectors are subjected to a weighted summation process or the like, which is not limited thereto.
For example, if the content of the current query sentence input by the target user is "i want to go to the uk to read the high school", the academic fee budgets 10000 yuan ", after the computer device obtains the current query sentence, the computer device extracts the keywords of" uk "," high school "," academic fee "and" 10000 yuan ", searches the vectors of the keywords in the predetermined keyword vector library, and performs weighted addition processing on each vector to obtain the current query feature of the target user.
If the keyword extracted from the current query sentence does not exist in the keyword vector library, the feature vector corresponding to the word close to the keyword is used as the vector of the keyword. The weights of the keywords may be preset, for example, the weights of the keywords of a category are the same, and for example, the weights of the keywords of a category having the greatest influence on the query purpose of the current query sentence are the highest.
S202, determining first recommendation information according to the current query characteristics and the information characteristics of the local candidate information.
The local candidate information may be information existing in the information recommendation platform, and the candidate information may be various types of information, for example, information, articles, books, and the like. The information feature of the local candidate information is feature information for representing the local candidate information, and may be a feature vector or a keyword contained in the local candidate information. The first recommendation information may be information that matches the current query feature, as determined from the local information.
Optionally, in this embodiment, the current query feature and the information features of all the local candidate information may be input into a pre-trained information recommendation model, where the information recommendation model analyzes and processes the received information, and outputs the first recommendation information. Another way to determine the first recommended information may be that after determining the current query feature (feature vector), the computer device determines information features (feature vectors) of each local candidate information, calculates a distance between the current query feature and the information feature of each local candidate information, and uses local candidate information corresponding to the information feature of the preset number of local candidate information closest to the current query feature as the first recommended information.
S203, determining second recommendation information through the chat robot model according to the current query characteristics.
The chat robot model can be a model which is trained in advance, can process query sentences input by a user and output information required by the user. Illustratively, chat robots ChatGPT (Chat Generative Pre-trained Transformer, chatGPT) may be provided. ChatGPT is a natural language processing tool driven by artificial intelligence technology, which can perform dialogue by understanding and learning human language, can interact according to the chat context, really chat and communicate like human, and even can complete the tasks of writing mails, video scripts, texts, translation, codes, writing papers and the like. The second recommendation information may be information matching the current query feature obtained after the chat robot model analyzes and processes the current query feature.
Specifically, in this embodiment, after the chat robot model receives the current query feature corresponding to the target user, it processes the current query feature and obtains the information matched with the current query feature.
It should be noted that the second recommended information is different from the first recommended information in that the first recommended information is selected from the local information; the second recommendation information is information generated by the chat robot model according to the current query characteristics. Thus, the second recommendation information may be more generic, more variable in content, and more matched with the current query characteristics.
S204, determining information to be recommended of the target user according to the first recommendation information and the second recommendation information, and feeding back the information to be recommended to the target user.
The information to be recommended is information fed back to the target user.
Specifically, in this embodiment, the first recommendation information and the second recommendation information may be both fed back to the target user as the information to be recommended. In another implementation manner, part of the content with the highest correlation with the current query feature is screened out from the first recommendation information and the second recommendation information, the part of the content in the first recommendation information and the part of the content in the second recommendation information are combined, and the combined content is used as information to be recommended and fed back to the target user. In another implementation manner, if the first recommendation information can be determined according to the current query characteristics and the information characteristics of the local candidate information, the first recommendation information is fed back to the target user as the information to be recommended. And determining second recommendation information according to the current query characteristics and the chat robot model when the first recommendation information is not determined according to the current query characteristics and the information characteristics of the local candidate information, and feeding the second recommendation information back to the target user as information to be recommended.
Alternatively, in this embodiment, the information to be recommended may be fed back through a short message, a fifth generation mobile communication technology message (5th Generation Mobile Communication Technology,5G), or the like. In addition, in this embodiment, the information to be recommended may be fed back to the target user in a voice broadcast manner.
In the information recommendation method, feature extraction is performed on the current query statement input by the target user to obtain the current query feature of the target user, and the first recommendation information is determined according to the distance between the current query feature and the information feature of the local candidate information. Because the information characteristics of the local candidate information are all determined in advance, the process of determining the first recommended information is more convenient. Further, in this embodiment, the first recommendation information is not directly used as the information to be recommended of the target user, but in order to ensure the matching between the information to be recommended and the target user, the current query feature is further analyzed and processed through the chat robot model, and the second recommendation information is generated. And determining final information to be recommended according to the first recommendation information and the second recommendation information and feeding back the final information to be recommended to the target user. The whole process can enable the matching degree of the information to be recommended and the target user to be higher, so that the aim of improving the information recommendation effect is fulfilled.
Further, in order to make the matching degree between the determined information to be recommended and the target user higher, in one embodiment, as shown in fig. 3, a specific manner of determining the information to be recommended of the target user is provided, which includes the following steps:
s301, determining occurrence frequency of the current query feature in the first recommendation information and the second recommendation information.
Specifically, in this embodiment, the number of occurrences of the current query feature in the first recommendation information and the second recommendation information may be queried and determined, respectively. For example, each feature word in the current query feature may be determined, the occurrence number of each feature word is queried in the first recommendation information, and the sum of the occurrence numbers of each feature word is used as the occurrence frequency of the current query feature in the first recommendation information.
S302, the first recommendation information and/or the second recommendation information with the occurrence frequency larger than a preset threshold value are used as information to be recommended of the target user.
The preset threshold may be used to determine whether the occurrence frequency of the current query feature in the first recommendation information or the second recommendation information reaches the information to be recommended.
Optionally, in this embodiment, if the occurrence frequency of the current query feature in the first recommendation information is greater than a preset threshold, the first recommendation information is used as the information to be recommended. And if the occurrence frequency of the current query feature in the second recommendation information is greater than a preset threshold value, the second recommendation information is used as the information to be recommended. Of course, if the occurrence frequency of the current query feature in the first recommendation information and the second recommendation information is greater than the preset threshold, the first recommendation information and the second recommendation information are both used as the information to be recommended.
Further, in one embodiment, in order to make the current query feature more accurate and better characterize the query requirement of the target user, in one embodiment, as shown in fig. 4, the manner of obtaining the current query feature of the current query statement input by the target user specifically includes the following steps:
s401, acquiring a current query sentence input by a target user.
Specifically, in this embodiment, when the target user inputs the current query sentence on the information recommendation platform (for example, a learning-reserved information consultation platform developed by a financial institution), the computer device may acquire the current query sentence input by the target user.
S402, determining the current query feature of the current query statement based on the user portrait of the target user.
The user portrait of the target user can be information which is determined in advance and used for representing the user characteristics, the query habits, the query preferences and the like of the target user.
Optionally, in this embodiment, the user portrait of the target user may be determined based on the matrix decomposition algorithm according to the historical query statement, the historical feedback information and the attribute information of the target user. The historical query statement may be a query statement input by a target user during a query operation on the information recommendation platform in a historical time. The historical feedback information may be recommendation information output by the computer device in response to the historical query statement. The attribute information may be basic information of the target user, such as gender, age, etc.
In this embodiment, the user image of the target user may be obtained by inputting the historical query statement, the historical feedback information and the attribute information of the target user into a pre-trained matrix-based decomposition model, and analyzing and processing the received data by the matrix decomposition model to output the user image of the target user. For example, in this embodiment, the manner of determining the user portrait of the target user based on the matrix decomposition algorithm may be to construct a scoring matrix according to the historical query statement, the historical feedback information and the attribute information of the target user (the scoring matrix records the occurrence times of the target user in each query operation and each query keyword). And decomposing the scoring matrix into a form of two matrix products according to the category of each query keyword and the occurrence frequency of each category. And then calculating the inner products of the two matrixes, sorting the inner products from large to small, and taking out the preset keywords with the front sorting and the corresponding occurrence times as the user portrait of the target user.
The user portrait of the target user is determined in the mode, and a basis is provided for determining the current query characteristics of the current query statement.
Optionally, in this embodiment, the current query statement and the user portrait of the target user may be input into a predetermined current query feature determination model, and the model processes the received data to obtain the current query feature of the current query statement. Another implementation manner may be that feature extraction operation is performed on the current query statement to determine statement features of the current query statement; and determining the current query characteristics of the target user according to the statement characteristics of the current query statement and the user portrait of the target user. Where the statement feature may be a keyword vector in the current query statement. Specifically, in this embodiment, each keyword vector in the current query sentence may be obtained, then the word vector of the keyword in the user image of the target user may be obtained, and the two types of keyword vectors may be summed to obtain the current query feature of the target user.
In the above embodiment, the current query feature of the target user is determined according to the statement feature of the current query statement and the user portrait of the target user, so that the determined current query feature can represent the requirement of the target user.
In addition, to enable the user profile of the target user to accurately characterize the query needs of the target user, in one embodiment, the historical feedback information includes historical recommendation information of the target user, and feedback information of the target user for the historical recommendation information. That is, the history feedback information includes history recommendation information recommended by the computer device for the target user when the history inquiry operation is performed, and an operation of the target user on the history recommendation information after receiving the history recommendation information. The operation of the target user on the historical recommended information comprises operations such as checking, downloading, collecting and the like, and information such as checking times, downloading records, collecting records and the like of the target user on the historical recommended information can be used as feedback information.
Further, in order to ensure that the user image of the target user can be updated in real time, and ensure that the user image used when determining the current query feature is more accurate when the target user performs the information query operation next time, in one embodiment, after feeding back the information to be recommended to the target user, as shown in fig. 5, the method further includes:
S501, current feedback information of a target user aiming at information to be recommended is obtained.
The current feedback information comprises information to be recommended fed back by the computer equipment for the target user in response to the current query statement, and processing records of the information to be recommended after the target user receives the information to be recommended. The processing mode of the information to be recommended is the same as the processing mode of the history recommended information, and is not described in detail herein.
Optionally, the method for obtaining the current feedback information of the target user for the information to be recommended may be to obtain the information to be recommended, and feed back the information to be recommended through the corresponding operation record. For example, an operation tracking program may be set on a page of the information to be recommended, and the operation tracking program is used for recording and feeding back an operation record of the information to be recommended to the target user to the computer device. And taking the information to be recommended and the operation record as current feedback information.
