Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, the every other embodiment that those of ordinary skills obtain, belongs to the scope of protection of the invention.
Referring to Fig. 1, the webpage pre-reading method that the embodiment of the present invention provides comprises the following steps:
S101: recording user is browsed behavioural information on webpage;
For the ease of understanding, first basic concepts is simply introduced.Browser, after opening certain webpage, can show the various elements that form this webpage in web interface, for example, may comprise word, picture, audio frequency, video etc. content, and in addition, a kind of common page elements that also may comprise links exactly.So-called link, conventionally be also referred to as hyperlink, that Web webpage is different from one of key character of other media, the link that visitor only need to click in webpage just can jump to the target place of link automatically, this target place is another webpage normally, that is to say, link is corresponding a webpage conventionally, (for the ease of distinguishing, this webpage can be called to target web corresponding to link, accordingly, just the webpage that includes this link in content of pages can be called to source web page, for example, in the content of pages of certain webpage A, comprise certain link, webpage B is pointed in this link, the source web page that webpage A is this link, webpage B is the target web of this link), when link is clicked, for browser, just be equivalent to receive the instruction of opening its corresponding target web.Usually, in web browser, linked object is different from other the non-linked contents in webpage by underscore and specific color conventionally, when mouse-pointing linked object, it will be become by " arrow " " hand shape " (under mouse scheme of acquiescence), just can open target web corresponding to link after clicking.The profile of linked object, can comprise two kinds of situations of text link and image links, also be, be used for the object of hyperlink, can be one section of text or a picture, but no matter be text link or image links, be the equal of all by modes such as word or thumbnails, to point out out the main contents of target web, user can be according to link text or image, probably determines whether to click the detailed content of this webpage that links to check that it is corresponding.Existence due to link, has changed traditional custom of reading in order webpage, when user sees a link, all means and can open, browse a more detailed information.For example in the news column of ，Mou portal website, conventionally will comprise a lot of links, conventionally can using the title of news as link text, after each link is clicked, all may open a webpage of introducing in detail news content, etc.
In existing pre-read schemes, generally can be after user opens certain webpage, the target web that the all-links comprising in this web page contents is corresponding reads in advance, when clicking certain link wherein as user, just can directly from buffer memory, take out web page contents, target web is presented in face of user as soon as possible.But, for some portal websites etc., owing to wherein including a large amount of links, therefore, if all read in advance the system resource that obviously can take much more very to wherein all linking corresponding target web, and user generally can not have requirements for access to every target web corresponding to link wherein, therefore, can cause a large amount of wastings of resources.
In the embodiment of the present invention, the behavior prediction of browsing that is intended to carry out in webpage according to user goes out the link that user may not can click next time, like this, when reading in advance based on this webpage, the link that just this user may not can be clicked next time forecloses, like this, just can avoid pre-read operation blindly to cause waste to system resource.For this reason, first need recording user to browse behavioural information on webpage, for example, page rolling event information of can comprise the link of the click of user in webpage, the residence time in webpage, carrying out in webpage etc.Wherein, the residence time in webpage refers to, from user, open webpage and start the time of experiencing to closing this webpage, certainly, generally, only have after the whole loadeds of web page contents, user can see the full content in webpage, when therefore, the residence time in webpage also can be from webpage loaded, start at.The page rolling event of carrying out in webpage refers to, user is by dragging the roller of scroll bar in page window or roll mouse or utilizing the modes such as mouse drag to check content of pages.Wherein, concrete page rolling event information can comprise direction, number of times of rolling etc., and these information can be monitored by hook() mode such as some critical system functions gets from operating system.
S102: browse that behavioural information determines that this user had browsed its anchor information but the link do not clicked by this user according to described;
Wherein, so-called anchor information is the text (conventionally also referred to as anchor text) for linking namely, or for picture of linking etc., as mentioned before, because anchor information generally can be pointed out out the main contents of target web in modes such as word or pictures, user can be according to anchor information, probably determine whether to click the detailed content of this target web that links to check that it is corresponding, therefore, if user has browsed the anchor information of certain link, but do not click this link, prove that this user may link corresponding target web to this and lose interest in, therefore, next time is while opening this webpage again, even if also there is this link in webpage, this user also may not can click this link, like this, when this user visits again this webpage next time, just can to target web corresponding to this link, read in advance again, to avoid causing waste.
Specifically, when definite this user had browsed the link of its anchor information, can there is multiple implementation.For example, under a kind of mode, if in step S101, record browse the link that behavioural information comprises that user clicks, the link that can click on webpage according to user, determines that user had browsed its anchor information but the link do not clicked by this user.
Because user is when the browsing page, generally all can be from numerous links, select interested link to click, therefore, if user has clicked certain link, prove that this user may browse near the anchor information of other links of this link, only may all lose interest in, so do not click.Therefore, the link that can click on webpage according to user, determines that user had browsed the link of its anchor information.During specific implementation, can first obtain each in webpage and be linked at the positional information in webpage, then, by with clicked link adjacent front N1 link and latter N2 link, be defined as that user had browsed its anchor information but the link do not clicked by this user, wherein, N1 and N2 can be preset fixed values.Also be, N1, N2 are changeless, for example, pre-set N1=4, N2=3, suppose to have 100 links in certain webpage, wherein by user, clicked for the 10th, wherein the 6th to the 9th and the 11st to the 13rd can have been browsed to anchor information but the link do not clicked by this user as user.Wherein, when obtaining the positional information being linked in webpage, concrete positional information can be linked at DOM(Document Object Model with each, DOM Document Object Model) path in tree represents, such as (0) div (1) a represents to start the 1st link the 0th div from root node, etc., about dom tree, hereinafter have introduction.
Under above-mentioned implementation, obtain user on webpage browse behavioural information time, only need to get the link that user clicked, just can get that user may browse anchor information but the link do not clicked by this user.
And under another kind of implementation, the value of N1, N2 can not be changeless, but according to the situation of browsing of reality and dynamic change.During specific implementation, obtain user on webpage browse behavioural information time, can also obtain the residence time and/or the page rolling event information of user on webpage, according to one of information of this two aspect or all, dynamically determine the value of N1, N2.For example, suppose that the page residence time is t, when t is less than a preset threshold value t1, N1=0, N2=0, also be, if the page residence time is very short, proves that user may not have enough time to browse the anchor information of other links, or may not see clearly, therefore, in this webpage, just there is not the link of being browsed anchor information by user.When t is greater than t1, the also increase of t in time and increasing of the value of N1 and N2, the step value that N1 and N2 increase can be the same or different.In addition, if the frequency table of the event of rolling is downwards shown r, the value of N2 increases with the increase of r, and similarly, if the number of times of the event that scrolls up is designated s, the value of N1 increases with the increase of s.
For example, suppose user's first some day to the click information of certain forum page as shown in Figure 2, can find out that user has clicked the 7th and the 15th link of forum, the page residence time of hypothetical record is 120 seconds, downwards rolling event times is 2, and the initial value of supposing N1 is that the initial value of 2, N2 is 1, the page residence time is 100 seconds when above, the value of N1, N2 all adds 1, and once, the value of N2 adds 1 in every rolling downwards, the N1 value calculating is 2+1=3, and N2 value is 1+1+1*2=4.Therefore, the 7th link of clicking according to user, this user who gets may browse anchor information but by this user, do not clicked be linked as the 4th to 6, the 8th to 11; And the 15th link of clicking according to user, this user who gets may browse anchor information but by this user, do not clicked be linked as the 12nd to 14, the 16th to 19, so just the relevant information of these links can be deposited in file, use when reading in advance.
Certainly, it should be noted that, for some webpages, the content of the target web that link is wherein pointed to may be exactly one piece of article or news report etc., for this link, if user is after click is opened target web and read its content, when opening again this webpage next time, even if still there is this link in webpage, user generally also can not click this again and linked, because this user had read the content in its corresponding target web.But, for other webpages, the target web that link is wherein pointed to may be the content that can upgrade, for example, in the webpage of some mhkc classes, wherein every link may be corresponding a topic, the promoter of topic may constantly link in corresponding target web and increase new content at this, and also may have other users this topic is commented on, etc.For another example, some link corresponding target web may be publishing in instalments of certain article, and author can constantly have new chapters and sections to be updated in target web, etc.In a word, for this link, when user visits again this webpage next time, may also can again click this link, therefore, the target web of the link correspondence that just this user can have been clicked reads in advance.Whether that is to say for the link of having clicked for user, according to the difference of classification under webpage, its target web is read in advance, situation can be different.Therefore, in embodiments of the present invention, can treat with a certain discrimination according to the classification under webpage.During specific implementation, can first obtain the classification described in webpage, for example, if find that webpage belongs to certain preset classification (news category etc.), the target web of the link correspondence that user can be clicked is also got rid of outside the scope reading in advance in the lump.If find that webpage belongs to mhkc, article and other classifications such as publishes in instalments, the target web of the link correspondence that user can be clicked reads in advance.Wherein, during classification under obtaining webpage, can rule of thumb wait information to obtain, for example, set up in advance various classifications, and collect the URL(Uniform/Universal Resource Locator of webpage of all categories, URL(uniform resource locator)) etc. uniqueness identification information, like this, just can find the classification under this webpage according to the URL of webpage.Or, also can determine the classification that webpage is affiliated according to the information such as key word in webpage, etc., no longer describe in detail here.
It should be noted that in addition, in actual applications, if also comprise navigation area in webpage, page turning district etc., wherein, navigation area generally also comprises some links, after these links are clicked, generally can make current web page jump to another column or channel etc., for example in Fig. 2 the leftmost side once being listed as the navigation area can be regarded as in this webpage, wherein show " stock community ", " financing community ", " reading community " etc. link, when clicking " stock community " link of navigation area, the article of delivering in the Jiu Doushi stock community showing in the article list on right side, etc..For this navigation area, the link that the link that user clicked also can be clicked when access next time often, therefore, if the webpage of may not can clicking when access this webpage next time using it as user is obviously inappropriate.In addition, for page turning district, generally also can comprise by numeral the link as link text, when user clicks correspondingly when digital, page jump can be gone on corresponding number of pages.The behavior of this click number of pages link is all generally the operation that user may carry out when each accessed web page, therefore, if the webpage of may not can clicking when access this webpage next time using it as user is also obviously inappropriate.
Therefore, in optional embodiment of the present invention, when finding user at accessed web page, after having clicked certain link, can first judge that whether clicked link is the link in the main contents list of webpage, if, recycling this chain fetches and determines that user had browsed its anchor information but link of not clicked by this user etc., if and find that clicked link is not the link in the list of webpage main contents, the link that can not utilize this chain to fetch to determine user to browse its anchor information but do not clicked by this user, and it can not carried out to record as the link that does not need to read in advance yet.
During specific implementation, because the navigation area of webpage generally has following features: the link in navigation area is generally text link, and the length of anchor text is generally shorter, and the number of words that the anchor text packets of different linking contains is all generally identical; Link in page turning district, owing to being generally that numeral with corresponding is done hyperlink, therefore, is also a kind of text link, and because anchor text is numeral, therefore also shorter.And main contents list is also generally to comprise a plurality of links, but the general title that adopts news etc. are as the anchor text of each link, so each anchor text is different in size, but generally all long.Therefore, based on These characteristics, just can be by the main contents list of webpage and navigation area, page turning is trivial separates.Concrete, in order to judge that whether clicked link is the link in the main contents list of webpage, can realize in the following ways: first, according to the position in the clicked dom tree that is linked at webpage, search the father node of clicked link; Judge and under this father node, whether comprise the child node similar to clicked link structure, if, add up the average length value of link anchor text corresponding to each child node under this father node, if this average length value is greater than certain preset threshold value, determine the link in this clicked main contents list that is linked as webpage.
Wherein, DOM provides access XML(Extensible Markup Language, extend markup language) medium of document information, this medium is a kind of hierarchical object model, and the structure of this level is a node tree generating according to XML document.An XML analyzer, after XML document is analyzed, no matter this document have many simply or how complicated, information wherein all can be converted to an Object node tree.In this node tree, there is a root node--Document node, every other node is all the descendent node of root node.After node tree generates, just can pass through node and content in DOM interface accessing, modification, interpolation, deletion, establishment tree.In dom tree, contents all in document all represent with node.A node can comprise other nodes again, and node itself also may comprise some information, such as the name of node, nodal value, node type etc.If certain node is the main contents list node of webpage, this node generally can have a plurality of child nodes of structural similarity, the corresponding link of each child node, the name that the structural similarity between different child nodes just can be by each child node, nodal value, node type etc. embody.
The above is to have introduced the in the situation that of having carried out clickthrough behavior user in webpage, this user of how to confirm had browsed its anchor information but the method for the link do not clicked by this user, and in actual applications, may there are following special circumstances: after user has opened a webpage, do not click any one link wherein.In this case, the embodiment of the present invention has provided that corresponding this user of determining had browsed its anchor information but the method for the link do not clicked by this user is introduced equally below.
If user is after opening a webpage, if stopped the sufficiently long time, and abundant number of times has also rolled the page downwards, but never any one link in webpage clicking, prove that user may lose interest in to whole links wherein, therefore in the time of, just can all regarding this webpage of access next time as, do not need the webpage reading in advance.During specific implementation, at recording user in webpage browse behavioural information time, just can record the page residence time and/or page rolling event information, if page residence time t is greater than certain threshold value r-max, and/or, roll the downwards frequency r of event of the page is greater than certain threshold value r-max, the whole links that comprise in this webpage all can have been browsed to its anchor information but the link do not clicked by this user as user.Certainly, if also comprise navigation area and page turning district in webpage, be not suitable for equally this example.Therefore, the page residence time and/or page rolling event information meet under the prerequisite of aforementioned condition, can also find out the main contents list in the page, then using the all-links in main contents list as user, browse its anchor information but the link do not clicked by this user.Wherein, while searching the main contents list of webpage, can carry out as follows: the whole nodes in traversal webpage dom tree, for each node, carry out respectively following operation: judge whether to exist a plurality of child nodes, and the structural similarity of each child node, if so, this node is main contents list node.
