As shown in fig. 2, in an embodiment, a method for comparing update speed of web page content includes the following steps:
step S202, acquiring keywords to be compared.
In one embodiment, the number of keywords to be compared may include one or more.
When the number of the keywords to be compared includes a plurality of keywords, the processing procedure described in the following step S204 to step S212 may be performed for each keyword to be compared, respectively. When two content items are compared in the following process, the content items corresponding to the same keyword are compared.
In one embodiment, the keywords to be compared may be preset and stored.
In one embodiment, keywords that specify a domain or specify a category with a popularity exceeding a threshold may be searched for as keywords to be compared. For example, a video name whose video category popularity exceeds a threshold may be searched as a keyword to be compared, where the video name may correspond to, but is not limited to, a name of a tv show or a name of a movie, etc.
In another embodiment, a keyword that specifies a top preset position in a network ranking list may be obtained as the keyword to be compared. For example, a music ranking list may be searched for a music name in the top preset position as a keyword to be compared, and so on.
In an embodiment, before step 202, the method for comparing the update speed of the web page content further includes setting a process of storing keywords to be compared; as shown in fig. 3, in one embodiment, the process includes the steps of:
step S302, acquiring preset webpage content classification categories.
In one embodiment, the categories of web page content categories include, but are not limited to, video, novel, music, news, and the like.
Step S304, requests web page content from each target website.
In one embodiment, the URL information of the target website may be preset and stored.
In one embodiment, the web page content of the website's home page may be requested from various target websites. Specifically, a web page pull request including a URL address of a website home page may be sent to each target website, and a source code corresponding to the home page returned by each target website may be received.
Step S306, the keywords corresponding to all categories in the webpage content of all target websites are crawled.
In one embodiment, the URL addresses of the web pages corresponding to the various categories may be extracted from the source code of the home page of the various target web sites. Furthermore, a webpage pulling request containing a webpage URL address corresponding to the category can be sent to the target website, and a webpage source code corresponding to the category returned by the target website is received.
The process is equivalent to that a user opens a home page of the target website and further clicks a link corresponding to the category on the home page, so that the browser receives a webpage source code corresponding to the category returned by the target website.
In one embodiment, the URL address of the web page corresponding to the href field in the html tag corresponding to the category may be extracted from the source code.
For example, in the following source codes, if the web page URL address corresponding to the href field in the html tag corresponding to the category "entertainment" is "http:// yule. iqiyi. com/", the web page URL address can be extracted as the web page URL address corresponding to the category "entertainment":
< h3> < a href ═ http:// yule. iqiyi. com/"> < span tear ═ entertainment" > entertainment > The method is characterized in that em </span </a > </h3 >.
Further, keywords corresponding to specified fields in html tags meeting preset rules can be extracted from the webpage source codes corresponding to the categories, and therefore keywords corresponding to the categories are obtained.
Furthermore, the method can also extract the webpage links corresponding to the sub-categories contained in the categories from the webpage source codes corresponding to the categories, send a webpage pulling request containing the webpage links to the corresponding target website, and receive the corresponding webpage source codes returned by the target website; and circulating the process until the webpage source codes corresponding to all the descendant categories contained in the categories are crawled, and extracting keywords corresponding to specified fields in the html tags which accord with preset rules from the received webpage source codes in the crawling process as the keywords corresponding to the categories.
The descendant categories contained in the categories comprise: subcategories and all categories branching from subcategories.
In step S308, repeated keywords are filtered from the extracted keywords.
And step S310, storing the residual keywords after filtering as the keywords to be compared.
In one embodiment, the keywords to be compared may be sorted according to the category corresponding to the keywords to be compared.
Step S204, circularly requesting search result webpages corresponding to the keywords from each target website.
The search result web page corresponding to the keyword is equivalent to a web page available for searching the keyword in the target web site. For example, if a user inputs a keyword in a search input box of a target website, and clicks a search button, a corresponding result webpage can be presented to the user, where the webpage is a webpage obtained by searching for the keyword.
In one embodiment, in the process of requesting a search result webpage corresponding to a keyword from a certain target website, a webpage link can be generated according to a preset rule, and the webpage link represents a search result webpage corresponding to the keyword requested from the target website; and further sending a webpage pulling request containing the webpage link to the target website, and receiving a webpage source code returned by the target website, namely a source code corresponding to the search result webpage corresponding to the keyword.
For example, a search result web page corresponding to the keyword "running bar brother" is requested from a target web site having a URL address "http:// www.iqiyi.com", the following web page links may be generated: http:// so. iqiyi.com/so/q _ brother of running bar? source is input; and a search result webpage corresponding to the keyword 'bear is absent' is requested from the target website, and the following webpage links can be generated: http:// so. iqiyi.com/so/q _ bear-on? source is input; wherein, the contained keywords of the two web page links are different.
After the search result webpages corresponding to the keywords are respectively requested from each target website, the corresponding processing of the steps S206 and S208 is executed aiming at the search result webpages, the search result webpages corresponding to the keywords are respectively continuously requested from each target website, the corresponding processing of the steps S206 and S208 is continuously executed aiming at the search result webpages, and the request process and the processing process are circulated until the preset circulation end condition is triggered.
In one embodiment, a search result webpage corresponding to the primary keyword is requested from all target websites respectively, and the corresponding processing of steps S206 and S208 is performed on the search result webpage, which is referred to as a primary loop or a primary loop process.
In one embodiment, the step S204 includes the steps of:
and requesting search result webpages corresponding to the keywords from each target website at intervals of preset time, wherein the preset time does not exceed a threshold value.
For example, a search result web page corresponding to the keyword is requested from each target website every 1 minute, and so on.
In one embodiment, the threshold value not exceeded by the preset duration is a smaller value; therefore, the effect similar to the effect of monitoring the updated webpage content of the target website in real time can be achieved.
Step S206, the target-divided website extracts content items corresponding to the updated keywords of the search result webpage requested by the circulation request relative to the search result webpage requested by the circulation request at the last time.
In an embodiment, in step S206, the search result webpage requested in the current loop corresponding to the same target website may be compared with the search result webpage requested in the previous loop, and the content item corresponding to the keyword updated by the target website is extracted.
As shown in fig. 4, in one embodiment, step S206 includes the steps of:
step S402, extracting the latest content items corresponding to the keywords in each search result webpage requested by the circulation.
In one embodiment, the latest content item corresponding to the keyword can be extracted at a preset specified position of the source code of the search result webpage.
The search result web page corresponding to the keyword comprises a search result list corresponding to the keyword.
The search result list may contain both exact match search results and fuzzy match search results. In one embodiment, search results that are fuzzy matches to the keywords in the search result list may be filtered out, and search results that are exact matches may be retained.
In some web sites, the most recent content item corresponding to the keyword is arranged in the search result list at a position that is ahead of other content items. Thus, in one embodiment, the content item at the first position may be extracted from the search result list data of the search results with fuzzy matches filtered for keyword correspondence in the search result web page source code as the latest content item for keyword correspondence.
In other websites, the latest content entry corresponding to the keyword includes a predetermined designated field, such as "update to" or the like, indicating the latest content. Therefore, in one embodiment, the content item corresponding to the preset specified field can be extracted from the search result list data corresponding to the keyword in the search result webpage source code as the latest content item corresponding to the keyword.
In step S404, the targetable website compares whether the extracted latest content item is the same as the content item recorded most recently.
For the latest content item corresponding to the keyword of a certain target website extracted currently, whether the latest content item is the same as the content item corresponding to the keyword of the target website recorded recently or not can be determined.
In step S406, the latest extracted content item different from the most recently recorded content item is acquired as the updated content item of the corresponding destination website.
If the latest content item corresponding to the keyword of a certain target website extracted currently is different from the content item corresponding to the keyword of the target website recorded recently, the latest content item extracted currently can be obtained as the updated content item of the target website corresponding to the keyword.
In an embodiment, each time the latest content item corresponding to the keyword of one target website is extracted, the currently extracted latest content item is compared with the content item corresponding to the keyword of the target website which is recorded recently, whether the two content items are the same or not is judged, and if the two content items are different, the currently extracted latest content item is obtained as the content item corresponding to the updated keyword of the target website.
In another embodiment, the latest content items corresponding to the keywords of all the target websites can be extracted, and then the extracted latest content items of each target website are compared with the content items corresponding to the keywords of the corresponding target websites which are recorded recently.
In step S208, if a content item corresponding to the updated keyword of the target website is extracted, the current loop processing time is used as the update time of the content item, and the corresponding relationship among the corresponding target website, the keyword, the content item, and the update time is recorded.
In an embodiment, if a content item corresponding to a keyword updated by a search result webpage of a certain target website requested by the current loop with respect to a search result webpage of the target website requested by the previous loop is extracted, the processing time of the current loop of the content item may be the receiving time of the search result webpage received in the current loop, or may be the current time, or may be the receiving time or a time within a slight fluctuation range of the current time, that is, a time within a small range which is not related to the receiving time or the current time.
Step S210, comparing the update time of the same content item corresponding to the update keyword between the target websites.
In one embodiment, the update times of the same content items corresponding to the update keywords of the two target websites may be subtracted to obtain the difference time.
Step S212, generating the updating difference data of the same content items corresponding to the updating keywords between the target websites according to the comparison result.
The updated difference data includes, but is not limited to, chart data and the like, which correspond to a plurality of expressions such as tables, graphs, bars, and the like.
In one embodiment, the keywords to be compared comprise a plurality of keywords of different categories, and the update difference data can be generated by category.
In an embodiment, the method for comparing the update speed of the web page content further includes the following steps: the update difference data is sent to a designated mailbox or a designated application program interface.
Automatically sending the update difference data to a designated mailbox may be used to notify the associated user of the update difference data.
And the updating difference data is automatically sent to the appointed application program interface, so that the application program interface can conveniently carry out preset logic processing on the updating difference data.
In an embodiment, the method for comparing the update speed of the web page content further includes the following steps: displaying the updated difference data according to the expression form corresponding to the updated difference data; and so on.
For example, if the update difference data is table data, the update difference data is shown in a table representation form, and so on.
In an embodiment, the method for comparing the update speed of the web page content further includes the following steps: extracting feature identifiers of the content items; in the step of recording the content items and comparing the content items, the recording and comparing are performed based on the feature identifiers of the content items.
In one embodiment, the feature identifier of the content item may be extracted at a preset specified position in the content item. For example, the content corresponding to the title field may be extracted from the html tag corresponding to the content item as the feature identifier of the content item. In one embodiment, the feature identifier may be further formatted according to a preset processing logic, so that the feature identifier conforms to a preset format.
For example, html source code corresponding to a content item is as follows:
<a class＝"album_link"data-playsrc-elem＝"firstlink"target＝"_blank"data-searchpingback-elem＝"link"data-searchpingback-param＝"ptype＝1-3-1"
href＝"http://www.iqiyi.com/v_19rro0o1ds.html#vfrm＝2-3-0-1"
data-pb ═ iqiyi & p2 ═ 9000 ═ title ═ 2015-02-24, people who had too great a fingerboard limit task who had too great a running bar brother, "data-tvlist-elem ═ 2015-02-24, people who had too great a fingerboard limit task;
content "2015-02-24: excessive task of finger board of brother of running bar" corresponding to title field can be extracted as the characteristic identifier of content item, and further 2015-02-24 can be formatted into 20150224 to meet the unified format.
In one embodiment, the content item may be semantically analyzed to obtain a feature identification of the content item. For example, the content item may be semantically analyzed by a semantic analysis tool.
For example, the target website is a news website, and after a content item corresponding to a keyword updated by a certain target website is extracted, semantic analysis can be performed on the content item to obtain a feature identifier of the content item.
Therefore, when the updating speeds of the two target websites for the same content items corresponding to the same keyword are compared, the updating speeds of the two target websites for the same feature identification corresponding to the same keyword can be compared.
FIG. 5 is a flowchart illustrating a method for comparing update speeds of web page contents in an embodiment. As shown in fig. 5, the method for comparing the update speed of the web page content includes the following steps:
step S502, acquiring keywords to be compared.
Step S504, circularly requesting search result webpages corresponding to the keywords from each target website.
Step S506, the latest content item corresponding to the keyword in each search result webpage requested by the current cycle is extracted.
Step S508, the targetable website compares whether the extracted latest feature identifier is the same as the feature identifier recorded most recently.
In step S510, the latest extracted feature identifier different from the most recently recorded feature identifier is obtained as the updated feature identifier of the corresponding target website.
Step S512, if the updated feature identifier is extracted, taking the current cycle processing time as the update time of the feature identifier, and recording the corresponding relationship among the corresponding target website, the keyword, the feature identifier, and the update time.
Step S514, comparing the updating time of the same feature identifier corresponding to the updating keyword between the target websites.
Step S516, according to the comparison result, the update difference data of the same feature identifier corresponding to the update keyword between the target websites is generated.
In one embodiment, the content items corresponding to the feature identifiers may be obtained, and update difference data of the content items corresponding to the feature identifiers corresponding to the update keywords between the target websites is generated according to a comparison result of update times of the same feature identifiers corresponding to the update keywords between the target websites.
The above-mentioned web content update speed comparison method is described below with reference to a specific application scenario. In one embodiment, the above-mentioned web content update speed comparison method is used for comparing the update speed of the target website video episode with the update speed of the novel.
A video episode often includes multiple episodes or periods requiring update times for updating the video episode relative to the target web site. And a novel often includes a plurality of chapters, and the update time of the novel chapters needs to be updated compared with the target website. The specific process is as follows:
(1) and acquiring pre-stored keywords to be compared of the category of the video episode and keywords to be compared of the category of the novel. The obtained keywords to be compared are shown in table 1 below.
TABLE 1
| Video episode name | Name of novel book |
| Speak out loud 2015 | Living people forbidden land |
| Where happiness is | Is pure and ambiguous |
| Great difference in health | Teacher legend |
| Huaxia micro-shadow | Immortal adverse flow of qi |
| I maybe some time... | Super doctor |
| Green swordsman | Killing spirit |
| Salad | Anti-solar blood soul |
| Big card driver | Super island owner |
| Orange road theater edition 1 wish to return to the past | Medicine for city immortal |
| Food to run | Mountain village stranger biography |
Similar processing as in steps (2) to (7) is performed for each keyword in table 1, and the keyword "loud 2015" is exemplified in steps (2) to (7).
(2) A search result webpage corresponding to 'speak out loud 2015' is requested from a target website: generating a webpage link according to a preset rule, wherein the webpage link represents a search result webpage corresponding to a request for 'speak out loud 2015' from a target website; and further sending a webpage pulling request containing the webpage link to the target website, and receiving a webpage source code returned by the target website, namely the source code of the corresponding search result webpage of the 'talking out aloud 2015'.
Taking the URL address of the home page of the target website as "http:// www.iqiyi.com" as an example, the following web page links can be generated: http:// so. iqiyi.com/so/q _ loud 2015? source is input; the web page link represents a corresponding search result web page that requests 2015 "aloud from the target web site.
(3) And filtering fuzzy matching search results from the search result list data contained in the source code of the search result webpage corresponding to the 'big speaking 2015' received by the target website, and extracting content items at a first position from the filtered search result list data to be used as latest content items corresponding to the 'big speaking 2015' in the target website.
(4) And extracting the content corresponding to the title field from the html tag of the latest content item corresponding to the "loud speaking out 2015" as the feature identifier of the latest content item, namely the latest feature identifier corresponding to the "loud speaking out 2015".
For example, the latest content entry html corresponding to "speak out loud 2015" is as follows:
<li class＝"album_item"><a class＝"album_link"data-playsrc-elem＝"firstlink"target＝"_blank"
data-searchpingback-elem＝"link"data-searchpingback-param＝"ptype＝1-3-1"href＝"http://vod.kankan.com/v/70/70367/470137.shtml？id＝731100"data-pb＝"rtgt＝kankan&p2＝9000"
the title is 2015-03-22, the lady pranks cause the andros to jump the building and cause the fracture data tvlist-elem is data tvlist-elem is >
2015-03-22, fracture is caused by the jumping of stairs of the boyfriend due to mischief of the girfriend.
The content '2015-03-22' corresponding to the title field, that is, the lady friend pranks the building and fractures the male friend, can be extracted from the content as the latest feature identifier of the content item, and the latest feature identifier corresponding to 'loud speaking out 2015' is obtained.
(5) And formatting the characteristic identifier according to a preset processing logic so that the characteristic identifier conforms to the preset format.
For example, removing the short horizontal lines included in the date, and removing the preset special symbols such as colon, quotation marks and the like included in the feature identifier, and the like, the obtained formatted feature identifier is: "20150322 fracture of male friend jumping from building due to mischief of female friend".
(6) Comparing whether the characteristic identification corresponding to the target website recorded recently is the same as '20150322 friend misopera causes man friend building jump to cause fracture', if not, taking the time of receiving the source code in the step (3) as the updating time or taking the current time as the updating time. For example, if the update time is 2015, 03, 26, 16, 29, "http:// www.iqiyi.com", "loud say 2015", "20150322" friend who prankly causes friend who jumps building and fractures "and" 2015, 03, 26, 16, 29 "are respectively used as the URL, keyword, feature identifier and update time of the target website, and the corresponding relationship between them is recorded.
And (5) circularly executing the steps (2) to (6) until a preset circulation end condition is triggered.
(7) And comparing the updating time of the same characteristic identification corresponding to the updated keyword between the target websites, and generating updating difference data of the same characteristic identification corresponding to the updated keyword between the target websites according to the comparison result.
In one embodiment, the update time differences between the same feature identifiers corresponding to the update keywords of the two target websites may be obtained by subtracting the update times of the same feature identifiers corresponding to the update keywords of the two target websites.
For example, an update difference data table as shown below may be generated.
If the updating difference time is positive, the updating time of the first target website is later than that of the second target website; if the difference time between the update times is negative, the update time of the first target website is earlier than the update time of the second target website.
