Detailed Description

Embodiments of the present application will now be described with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present application. As can be known to those skilled in the art, with the development of technology and the emergence of new scenes, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

The embodiment of the application provides a method for acquiring hot news, which can acquire hot news with the highest rank in hot news issued by various news issuing sources in the whole network, thereby improving the efficiency of acquiring the hot news in the whole network. The embodiment of the application also provides a corresponding server, a terminal and a computer readable storage medium. The following are detailed descriptions.

Fig. 1 is a schematic diagram of an embodiment of a system for acquiring a news hotspot in the embodiment of the present application.

As shown in fig. 1, an embodiment of the system for acquiring a news hotspot provided by the embodiment of the present application includes a server 10, a network 20, and a plurality of news distribution sources 30, where the server 10 and the plurality of news distribution sources 30 are communicatively connected through the network 20.

The plurality of news feed sources 30 may include, for example, news feed 1, news feed 2, and news feed N, where N is an integer greater than 2. Each news feed may be understood as a news web site, which may be a collaboration web site, or a news web site that is only available for diversion, such as: the existing news-publishing websites in the networks such as fox searching news, wave news, xinhua network, south network and the like.

Each news distribution source distributes hot news counted or maintained by the news distribution source. The server 10 may obtain, from each news distribution source, the initial hot news on each news distribution source through the network 20, where the initial hot news is the hot news of each news distribution source. The initial hot news published on each news publication source may be the same or different or may be partially the same. Therefore, after acquiring the initial hot news from each news distribution source, the server 10 clusters the initial hot news, that is, determines the same or similar hot news. For hot news with the same or high similarity, the hot news can be clustered into one news. This clustered news may be understood as intermediate hot news, no identical or similar initial hot news belonging to the non-clustered initial hot news. Then, the server 10 selects the intermediate hot news after the clustering process and the initial hot news which is not clustered according to the heat degree, and determines target hot news.

If the total sum of the initial hot news obtained from each news distribution source is marked by a set a, for example, 10 initial hot news { a1, a2, a3, a4, a5, a6, a7, a8, a9, a10} are included, and the server 10 clusters, if a1, a2, and a3 are the same or very similar news, the server 10 clusters a1, a2, and a3 into an intermediate hot news b1, where b1 may include all the contents of a1, a2, and a3, and only makes an event progress association according to the sequence of occurrence time of a1, a2, and a 3. If a6, a7 and a8 are the same news or the news with high similarity, the server 10 clusters a6, a7 and a8 into an intermediate hot news b2, and other a4, a5, a9 and a10 are all different and dissimilar hot news, so that a4, a5, a9 and a10 are all initial hot news which is not clustered. The clustered hot news set B may include B1, a4, a5, B2, a9, and a10, and the hot news in the set B may be understood as intermediate hot news plus the original hot news that is not clustered. And then the server judges the popularity of each hot news in the set B again, and if the popularity of B1, a4, a5, B2 and a9 is greater than the popularity threshold, it can be determined that B1, a4, a5, B2 and a9 are the target hot news. The target hot news can also be understood as a set C, which includes b1, a4, a5, b2, and a 9. It should be noted that this scenario is only an example, and in fact, there are many initial hot news released by each news releasing source, that is, there may be many hot news in the sets a, B, and C. The number of hot news in each set in this scenario example should not be construed as a limitation on the number of hot news in the embodiments of the present application.

The above is a description of a scene of a system for acquiring hot news, and the following is a method for acquiring hot news at a server side, also in combination with the above system.

As shown in fig. 2, an embodiment of the method for obtaining hot news provided in the embodiment of the present application includes:

101. the method comprises the steps of obtaining initial hot news from each news release source in a plurality of news release sources, wherein the initial hot news is the hot news of each news release source.

102. And clustering the initial hot news with the similarity larger than the similarity threshold value in the initial hot news to obtain intermediate hot news.

103. And determining the intermediate hot news with the heat degree larger than the heat degree threshold value and the initial hot news which is not clustered and has the heat degree larger than the heat degree threshold value as target hot news.

The scheme of the method provided by the embodiment of the present application can be understood by referring to the description and examples in the above system scheme, and repeated description is not repeated here.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the acquiring initial hot news from each news distribution source in the multiple news distribution sources may include:

determining a hot news layout corresponding to each news release source;

and acquiring the respective hot news of each news release source from the corresponding position of the hot news layout corresponding to each news release source.

In the embodiment of the present application, the hot news layout corresponding to each news issue source is usually different, for example: as shown in fig. 3A, if the news distribution source 1 is a station a news, the hot news page of the station a is a hot news center. As shown in fig. 3B, the news distribution source 2 is B station news, and the hot news page of the B station news is the hot news on the left. As shown in fig. 3C, the news distribution source 3 is the C station news, and the hot news page of the C station news is the hot news top. Therefore, when the server acquires the initial hot news from each news release source, the server acquires the hot news of each news release source at a corresponding position on the hot news layout according to the hot news layout corresponding to each news release source. If the news distribution source 1 is aimed at, the initial hot news of the news distribution source 1 is obtained from the middle of the layout, if the news distribution source 2 is aimed at, the initial hot news of the news distribution source 2 is obtained from the left side of the layout, and if the news distribution source 3 is aimed at, the initial hot news of the news distribution source 3 is obtained from the left side of the layout. Therefore, the efficiency of acquiring the initial hot news can be improved without searching the full page.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the acquiring the hot news of each news issue source may include:

and acquiring hot news of each news release source in an acquisition time period, wherein the hot news in the acquisition time period comprises the hot news at the initial moment of the acquisition time period and newly-added hot news after the news release source page is refreshed in the acquisition process.

In the embodiment of the application, the initial hot news of each news release source is updated, and if the server acquires the initial hot news of each news release source in real time to update in real time, the computing resources are wasted, so the server can acquire the hot news of each news release source at regular time and can specify an acquisition time period, the initial hot news of each news release source is acquired at the initial moment of the acquisition time period, and the hot news of each news release source is acquired at the end moment of the acquisition time period. And real-time acquisition is not needed, so that the accuracy of the data is ensured, and the waste of computing resources is reduced. The new hot news that will be added during the acquisition period can be understood with reference to fig. 4. At the start time of the acquisition period, as shown in fig. 4 (a), the page includes hot news 1, hot news 2, and hot news 3, and at the end time of the acquisition period, as shown in fig. 4 (b), the page includes hot news 1, hot news 2, and hot news 4. Then the hot news 4 is used to replace the hot news 3 after the page is refreshed, and the server acquires the hot news 1, the hot news 2, the hot news 3, and the hot news 4 in the acquisition time period.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the clustering initial hot news of which the similarity is greater than the similarity threshold in the initial hot news to obtain intermediate hot news may include:

determining the field to which the initial hot news belongs;

In the process of clustering the initial hot news, in order to reduce the calculation amount of the word-by-word analysis of the news, the field to which each initial hot news belongs may be determined, and the fields may include: social, financial, scientific and educational aspects, and then similarity calculation and clustering are performed on the initial hot news in the same field.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the method may further include:

In this embodiment, the entity may be a company, a unit, or a person in news, and the keyword may be a verb or a noun related to the entity, such as: the love art recruits news on the market, wherein the love art can be an entity, and the recruiting can be keywords.

For initial hot news in the same field, the same or very similar hot news may exist, or different or dissimilar hot news may exist, so that the similarity needs to be further calculated according to the entity and the keyword.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the determining, according to the entity and the keyword, the similarity of each initial hot news in the same field may include:

determining the occurrence frequency and position of the same entity in each initial hot news in the same field;

and for each initial hot news in the initial hot news meeting the initial clustering conditions, carrying out similarity scoring on each initial hot news according to keywords.

In the embodiment of the present application, the more times the same entity appears in different hot news, the higher the correlation of the different hot news is, of course, the less times the same entity appears may be, but the more important the position of the occurrence is, for example, the position of the occurrence in the beginning of the news, the higher the correlation of the different hot news is. Therefore, when the initial hot news meeting the initial clustering condition is determined, a weighted calculation can be performed according to the occurrence times and positions of the entities, and then which news belong to the initial hot news meeting the initial clustering condition is determined according to the calculation result. And determining similarity according to the keywords aiming at the initial hot news meeting the initial clustering condition, wherein if two initial hot news are provided, one is the Aiqi skill recruiting and marketing, and the other is the Aiqi skill purchasing other video websites. When an entity judges, the occurrence frequency of "love art" in two news is many, and the occurrence position is also important, but when the keywords are judged, one keyword is "fund raising" and the other keyword is "purchase", the similarity of the two hot news can also be determined to be not high, for example: the similarity threshold is 8 points, in this case, the similarity is calculated to be 3 points, and if the similarity is less than 8 points, the final clustering condition is not satisfied. If two initial hot news are available, one is the love art fund and the other is the love art fund and the amount of the love art fund is 5 hundred million dollars. When entity judgment is performed, the number of occurrences of "love art" in two news is large, and the locations of the occurrences are also important, and when keywords are judged, one keyword is "fund raising", and the other keyword is "fund raising", it can also be determined that the similarity of the two hot news is high, for example: the similarity threshold is 8 points, in this case, the similarity is calculated to be 9 points, and if the similarity is greater than 8 points, the final clustering condition is satisfied. The two hot news can be clustered into one middle hot news, and the clustered middle hot news can retain all contents of the two hot news and only make an event progress correlation according to the time sequence.

Optionally, in another embodiment of the method for obtaining hot news provided in the embodiment of the present application, the determining a domain to which the initial hot news belongs may include:

In the embodiment of the application, the link information of the news release source generally includes prompt information about a field, such as sports news, and the link information may also include prompt information that "sport" appears more often, and certainly, there may be no prompt information related to the field in the link information of the news release source, so that the field to which the initial hot news belongs needs to be further determined according to the text keyword.

Optionally, in another embodiment of the method for acquiring hot news provided in the embodiment of the present application, the determining, according to the link information of the news release source from which the initial hot news comes and the text keyword of the initial hot news, a field to which the initial hot news belongs may include:

In the embodiment of the application, the text keywords can be extracted from the text of the initial hot news, the text keywords can be extracted by a term frequency-inverse document frequency (TF-IDF) technology, and the TF-IDF technology is a common weighting technology for information retrieval and data mining.

In the embodiment of the application, the domain determined in the link information of the news publishing source is determined as the pre-estimation domain, and then cosine similarity calculation is performed according to the text keywords and the central vector in the pre-estimation domain, wherein the initial pre-estimation domain central vector is the vector of the text keywords of the first hot news. If the cosine similarity of the text keyword vector is greater than a preset threshold, the estimated field is judged to be the field to which the initial hot news belongs, and if the cosine similarity of the text keyword vector is less than the preset threshold, the estimated field is judged not to be the field to which the initial hot news belongs. When the pre-estimated field is the field to which the initial hot news belongs, the text keyword vector of the hot news can be added to the field set, and the central vector is changed into the geometric central point of two similar vectors. As the content gradually adds iterations, the center vector will converge.

In the embodiment of the application, the authority of a news release source from which the initial hot news corresponding to the intermediate hot news comes, the browsing times of the user, the approval times, the comment times and the comment times of the user and the like can be considered when determining the popularity of the intermediate hot news. Meanwhile, the weight of news can be increased according to hundred-degree ranking and microblog hot spots, and the news with the top rank can be finally calculated.

The process of acquiring hot news described above in the embodiment of the present application mainly includes three processes of acquiring initial hot news, clustering the acquired initial hot news, and calculating the hot degree of the hot news, and for the three processes, reference may also be made to the processes in the following drawings for understanding.

As shown in fig. 5, the acquisition process for the initial hot news may include:

201. and acquiring a news release source list.

The news feed may be a different news web site.

202. And determining a hot news layout.

Since the arrangement areas of the hot news on different news websites may be different, different hot news acquisition templates can be configured for different news websites.

203. Page changes are monitored.

The step is to monitor the page change of the hot news on each news website.

204. Pulling the initial hot news.

When the initial hot news is pulled, a javascript script can be called to automatically refresh the page, and incremental news is obtained according to data changes before and after refreshing.

205. And extracting the text of the hot news.

The extracted text may be stored in a database.

206. And generating the abstract.

The abstract can be generated by extracting the core content in the body through a deep neural network.

207. And (6) incremental warehousing.

Hot news for the increment is also stored in the database.

As shown in fig. 6, the clustering process for the obtained initial hot news may include:

301. the link information is analyzed.

And analyzing whether the suggestive information related to the field exists or not from the link to determine the pre-estimated field.

302. And extracting the text keywords.

Keywords are extracted from the text content.

303. And determining the domain similarity.

And determining whether the estimated field is the field to which the initial hot news belongs according to the text keywords.

304. And determining the estimated field as the field to which the initial hot news belongs according to the field similarity.

The processes 301 to 304 described above may be understood as processes of domain classification.

305. Entities are extracted from the initial hot news.

306. Keywords are extracted from the initial hot news.

307. And determining that the similarity of the initial hot news in the same field is greater than a threshold value according to the entity and the keyword, and the initial hot news belong to the same or similar news.

308. And carrying out hierarchical clustering.

Hierarchical clustering is to associate two or more initial hot news, and the association relationship between the two or more initial hot news can be established only according to the time sequence without changing any one of the initial hot news.

The above 305 to 308 may be understood as a process of clustering.

As shown in fig. 7, the hot news popularity calculation process may include:

401. and obtaining the authority level of the news release source.

And the number of browsed initial hot news by the user, and indexes such as praise and comment can be obtained.

402. And news timeliness.

The timeliness of news is used as a weight for calculating the popularity.

403. The number of matches is weighted.

If a plurality of news distribution sources all distribute the same or similar initial hot news, the initial hot news can be promoted according to the distribution number.

404. And scoring the news quality.

The news quality affects whether the user will browse or not, so the news quality also affects the popularity of the news.

The above 401 to 404 can be understood as a base score.

405. Hundred degree rank weighting.

406. And weighting the microblog hot spots.

And for the initial hot news subjected to basic scoring, weighting and adjusting the hot score according to the ranking position of the initial hot news in hundredths and the hot situation in the microblog.

In the above embodiments, all of the processes of the server acquiring the hot news are described, and a process of interactively displaying the acquired target hot news by the server and the terminal in the embodiment of the present application is introduced below with reference to fig. 8.

As shown in fig. 8, another embodiment of the system for acquiring hot news provided by the embodiment of the present application includes a server 10 and a plurality of terminals 40, and the server 10 and the terminals 40 communicate via a network 20. Any one of the terminals 40 for which the news application provided in the embodiments of the present application is installed may request hot news from the server. The process may be that the terminal 40 responds to a selection operation of the news application, and the selection operation may be a click operation of the news application by the user. The terminal 40 sends a hot spot request message for the news application to the server 10, and the server 10 determines current target hot news, which is the latest target hot news when the hot spot request is received. The terminal 40 receives the target hot news returned by the server 10 and then displays the target hot news.

In the embodiment of the present application, the display style of the target hot news may be that the terminal 40 allocates each target hot news to a preset display style for displaying according to the hot ranking of the multiple target hot news returned by the server 10.
