Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the data mining-based associated content extraction method or the data mining-based associated content extraction apparatus of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include terminal devices 101, 102, 103, networks 104, 105, a first server 106, and a second server 107. The network 104 is used to provide the medium of a communication link between the terminal devices 101, 102, 103 and the first server 106, and the network 105 is used to provide the medium of a communication link between the first server 106 and the second server 107. The networks 104, 105 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The user may use the terminal devices 101, 102, 103 to interact with the first server 106 via the network 104 to receive or send messages or the like. The terminal devices 101, 102, 103 may have various communication client applications installed thereon, such as a search application, a web browser application, a shopping application, a mailbox client, social platform software, and the like.
The terminal devices 101, 102, 103 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III, mpeg compression standard Audio Layer 3), MP4 players (Moving Picture Experts Group Audio Layer IV, mpeg compression standard Audio Layer 4), laptop portable computers, desktop computers, and the like.
The first server 106 may be a server that provides various services, such as a background search server that provides search results for search requests sent by the terminal devices 101, 102, 103. The background search server may analyze and perform other processes on the received data such as the search request, and feed back the processing results (e.g., the search results) to the terminal devices 101, 102, and 103.
It should be noted that the method for extracting associated content based on data mining provided by the embodiment of the present application is generally executed by the first server 106, and accordingly, the associated content extracting apparatus based on data mining is generally disposed in the first server 106.
The second server 107 may be a server that provides various services, for example, a background server that generates comment tags for search keywords to which search results are directed by crawling the search results on the first server 106. The second server 107 may obtain a search result corresponding to the search keyword on the first server 106, generate a comment tag corresponding to the search keyword, and feed back the generated comment tag to the first server 106.
It should be understood that the number of terminal devices, networks, first servers and second servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
It should be noted that the method for extracting associated content based on data mining provided in the embodiment of the present application is generally executed by the second server 107, and accordingly, the associated content extracting apparatus based on data mining is generally disposed in the second server 107.
With continued reference to FIG. 2, a flow 200 of one embodiment of a data mining based associated content extraction method in accordance with the present application is illustrated. The associated content extraction method based on data mining comprises the following steps:
In this embodiment, the electronic device (e.g., the second server 107 shown in fig. 1) on which the associated content extraction method based on data mining operates may obtain the data to be processed from the electronic device (e.g., the first server 106 shown in fig. 1) communicatively connected thereto through a wired connection manner or a wireless connection manner. It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
The data to be processed obtained in this step may include, but is not limited to, semi-structured data such as articles, comments made by users in social applications, and the like. Here, the semi-structured data may mean, for example, data that can form structured data by appropriate data processing.
In some application scenarios, the acquiring of the to-be-processed data of this step may be associated with a search request of a user, for example. Specifically, when a user sends a search request for a certain search keyword to a search server (e.g., the first server 106 shown in fig. 1) through a terminal device (e.g., the terminal devices 101, 102, 103 shown in fig. 1), an electronic device (e.g., the second server 107 shown in fig. 1) on which the data mining-based associated content extraction method of the present embodiment operates may receive a search result sent thereto by the search server as data to be processed for the current search keyword. In these application scenarios, the search keyword input by the user can be regarded as a preset query object in this step.
Alternatively, in other application scenarios, the obtaining of the to-be-processed data at this step may be independent of the search request of the user. Specifically, the electronic device on which the associated content extraction method based on data mining of this embodiment is executed may actively grab the to-be-processed data including the preset query object. For example, the electronic device may actively crawl pending data containing keywords a from servers of various large social platform applications.
Here, the candidate comment tag associated with the preset query object may be understood as information that is likely to be a feature of the preset query object, for example.
In some application scenarios, it is assumed that a preset query object is a "Convolutional Neural Network (CNN)", and a content of a certain piece of data to be processed refers to both a Convolutional Neural Network and a cyclic Neural Network (RNN), so that some evaluation words, such as "high accuracy", "fast model operation speed", "directional cycle", and the like, which may be used as features of the CNN, in the data to be processed may be understood as candidate comment tags.
And step 230, screening the comment tags from the candidate comment tags.
The purpose of this step is to remove the candidate comment tags that do not belong to the preset query object from the candidate comment tags associated with the preset query object obtained in step 220, so that the association relationship between the comment tags obtained by screening and the preset query object is more accurate.
This is illustrated by the example of step 220. The candidate comment tags extracted in step 220 for the preset query object "Convolutional Neural Network (CNN)" include "high accuracy", "fast model operation speed", and "directional loop". In the step, a candidate comment label which is obviously 'directional circulation' and can not be used for evaluating the characteristics of the CNN is removed, so that the comment label obtained by screening has high accuracy and high model operation speed and has higher matching degree with the CNN.
In addition, the comment tag obtained by screening in the step can be used as one of the extracted associated contents related to the preset query object.
And 240, determining the presentation sequence of each comment tag based on the click rate of the user on each comment tag.
In step 230, the comment tags associated with the preset query object have been determined. When a user initiates a search request with the preset query object as a search keyword, the comment tag associated with the preset query object can be sent to the terminal device used by the user along with a search result page.
When the comment tags are presented on the search result page, the comment tags with a large click amount of the user are presented at a more remarkable position, so that the comment tags can be prompted to have high attention in a period of time, and therefore the user can further screen and preferentially display the search results by clicking the comment tags with high attention.
Still taking a preset query object of a Convolutional Neural Network (CNN) as an example, when a user searches by using the Convolutional Neural Network as a search keyword, the comment tags "high accuracy", "fast model operation speed" associated with the Convolutional Neural Network can be sent to the terminal device used by the user together with the search result page. In addition, the comment tag of "fast model operation" is displayed preferentially in the search result page compared with other comment tags (for example, "high accuracy") due to the high user click rate. In this way, if the user clicks "model computation speed is fast", the search results of the "convolutional neural network" can be further screened, and the search results associated with the label "model computation speed is fast" can be screened out.
According to the method for extracting the associated content based on the data mining, the to-be-processed data including the preset query object is obtained, the candidate comment tags associated with the preset query object are determined from the to-be-processed data, the comment tags are screened out from the candidate comment tags, and finally the presentation sequence of the comment tags is determined based on the click amount of the user on the comment tags, so that the comment tags of the preset query object are intelligently extracted and presented according to the priority.
In some optional implementations of this embodiment, in the determining the to-be-processed data in step 220, the candidate comment tag associated with the preset query object may further include: and extracting candidate comment tags associated with a preset query object from the data to be processed based on a natural language processing method.
Natural Language Processing (NLP) is a technology for studying the Processing of human Language by computers. The method comprises the branches of syntactic semantic analysis, information extraction, text mining, machine translation, information retrieval and the like. Natural language processing methods are widely studied and will not be described herein.
In some optional implementations, the screening of the comment tags from the candidate comment tags of step 230 may further include: and based on a preset matching rule, removing candidate comment tags which are not matched with a preset query object from the candidate comment tags to screen out the comment tags.
In some application scenarios, for example, the preset matching rule includes: the comment tags for evaluating men are not available for women. Then, assuming that the candidate labels obtained in step 220 include "good performing", "beautiful" and "general", and the preset query object is a woman, it is obvious that the candidate comment label of "general" will be removed.
Referring to fig. 3, a schematic flow chart diagram 300 of another embodiment of the data mining-based associated content extraction method of the present application is shown.
The method of the embodiment comprises the following steps:
And step 320, determining candidate comment tags associated with the preset query object in the data to be processed.
And step 330, screening the comment tags from the candidate comment tags.
And step 340, determining the presentation sequence of each comment tag based on the click rate of the user on each comment tag.
The steps 310 to 340 are similar to the steps 210 to 240 of the embodiment shown in fig. 2, and are not described herein again.
Unlike the embodiment shown in fig. 2, this embodiment further includes:
and step 350, obtaining comment data containing a preset query object from a preset hotspot data source.
Here, the preset hotspot data source may be, for example, recent hot search data of a preset social platform. Assume that the preset query object is a movie recently shown. The movie name of the movie may be a preset query object. If the movie name appears in the hot search data of a certain social platform, comment data containing the movie name in the hot search data of the social platform can be acquired.
And step 360, determining the weight of each comment data.
By determining the weight of the comment data, the degree of association between the comment data and the preset query object, and/or the quality of the comment data itself can be determined.
By determining the display order of the comment data based on the weight of the comment data, the comment data with higher association degree and/or the comment data with higher quality level with the preset query object can be preferentially displayed to the user.
In some optional implementation manners, the obtaining of the comment data containing the preset query object from the preset hotspot data source in step 350 in this embodiment may further include:
step 351, obtaining candidate comment data containing a preset query object from a preset hotspot data source.
And step 352, determining comment data from the candidate comment data based on the page browsing amount of each piece of candidate comment data.
Therefore, comment data which are associated with the preset query object and have higher user attention can be further screened from the hotspot data source.
In some optional implementations, the determining the weight of each comment data in step 360 of this embodiment may include, for example, at least one of the following:
step 361, determining the weight of the comment data based on whether the comment data has the hot words with the co-occurrence frequency of the preset query object exceeding the preset frequency. By determining whether the comment data has the hot words of which the number of co-occurrence times with the preset query object exceeds the preset number, the core hot spots (namely, the hot words) concerned by the user in the comment data can be extracted, and the weight of the comment data is increased so as to be preferentially displayed.
Step 362, based on the machine learning algorithm, determines the quality score of the review data and determines the weight of the review data based on the quality score. In some application scenarios, although the comment data in the hotspot data source has a certain degree of association with the preset query object, the comment data has a more obvious tendency of "twitching tendency", and then the comment data can be considered to have a lower quality score. In these application scenarios, the comment data may be input into a machine learning model (e.g., a neural network model) trained in advance, so as to obtain a quality score for the comment data, and comment data with a higher quality score may be given a higher weight so as to be preferentially displayed.
On the other hand, in some application scenarios, there may be some cases where the comment data in the hotspot data source may contain spam that is not desired to be presented to the user, such as comment data advertised by hotspot data, comment data with inappropriate speech, and so on. In the application scenarios, the comment data can be filtered and eliminated by adopting a machine learning method. For example, the comment data containing spam content may be filtered out using the same machine learning model that determines the quality score, or a separate machine learning model may be used.
And step 363, determining the weight of the comment data based on the click rate of the user on the comment data. By determining the weight of the comment data based on the click amount of the user on the comment data, comment data that the user is more interested in (comment data having a higher click amount) can be given a higher weight so as to be preferentially displayed.
It is to be understood that, if at least two of the steps 361 to 363 are adopted to determine the weight of the comment data, the weights determined by at least two of the steps may be weighted and added, so as to determine the final weight of the comment data.
In some optional implementation manners, the method for extracting associated content based on data mining according to this embodiment may further include:
and 380, determining the emotional tendency of each comment data based on the natural language processing tool, and determining the favorable rating of the preset query object based on the emotional tendency of each comment data.
For example, in some application scenarios, the emotion score of each piece of comment data for a preset query object (for example, the positive tendency is assigned 1, the negative tendency is assigned 0, and the neutral tendency is assigned 0.5) may be determined based on a natural language processing tool, and finally, the good rating of the preset query object is determined in a certain operation manner.
And step 390, generating a rating curve of the preset query object based on the rating of the preset query object in each preset time period.
It is understood that, since the number of the comment data gradually changes (e.g., increases) with the lapse of time, the rating of the preset query object will also change accordingly. The favorable rating curve of the preset query object is generated based on the favorable rating of the preset query object in each preset time period, so that the development trend of the favorable rating of the preset query object in a period of time can be visually displayed.
