Description

Advertising message put-on method and device
Technical field
The application relates to internet information processing technology field, particularly relates to a kind of advertising message put-on method and device.
Background technology
Along with developing rapidly of Internet technology, the information on webpage is more and more abundanter, and in order to better use the information on webpage, people constantly pursue the technology can effectively organizing and utilize network information, and therefore advertising message technology of throwing in is arisen at the historic moment.Advertising message input refers in the webpage opened user throws in applicable advertising message, to attract the click of user.
When displaying advertising messages, can throw in based on web page contents, this input technology also can be called contextual advertisement information input technology, such as, user is when browsing the webpage relevant to automobile, the advertising message that sale of automobile, car insurance, automobile journal etc. are relevant renders to this webpage, or user is when browsing the webpage how obtaining bank loan, the advertising message such as bank loan or personal loan is rendered to this webpage, to make user's click of carrying out easily and fast browse, therefore ad placement company also obtains income.
In prior art, usually the quality of the advertising message of input is evaluated by correlativity, it reflects the serviceability of advertising message to user, the correlativity of advertising message refers to the anastomose property of search keyword/web page contents etc. and advertising message, if carry out the input of advertising message based on web page contents, then the correlativity of advertising message refers to the anastomose property of web page contents and advertising message.When carrying out the input of advertising message based on web page contents, owing to throwing in for principle with the content for particular webpage, between the advertising message of therefore throwing in and web page contents, there is larger correlativity, so when user browses webpage, the possibility that the relevant information provided advertisement is become interested is just comparatively large, thus can produce more click behavior or navigation patterns for advertising message.
As shown in Figure 1, for carrying out the method flow diagram of advertising message input in prior art based on web page contents, its concrete treatment scheme is as follows:
Step 11, extracts the body matter of the webpage of advertising message to be put;
Step 12, from the body matter extracted, determines each Web page text keyword;
Step 13, by each Web page text keyword determined, forms the matching keywords set of mating advertising message;
Step 14, mates with each advertising message respectively by matching keywords set;
Step 15, renders to the advertising message matched in this webpage.
Existing advertising message put-on method mainly carrys out match advertisements information according to Web page text keyword, when the body matter of webpage enriches very much, Web page text keyword can reflect the subject content of webpage more accurately, therefore the advertising message matched and the correlativity of web page contents are just comparatively large, and the input precision of advertising message is higher.But, now there is various webpage on the internet, the body matter of some webpage is very abundant, such as news web page etc., but also seldom or not there is body matter, such as picture webpage, video web-pages etc. in the body matter of some webpage, the to the effect that picture of these webpages or video, introductory content of text is less, also can be called short text webpage, and short text webpage has occupied a very large proportion of webpage on internet.When the webpage of advertising message to be put is short text webpage, because the body matter of webpage is considerably less, the Web page text keyword then determined according to body matter just correctly cannot reflect the subject content of webpage, correlativity between the advertising message so matched and web page contents is just lower, and the input precision of advertising message is also lower.Such as, certain automobile information class webpage, the most content of webpage is the picture of automobile, only there is " parameter configuration table " this body matter, only " golf " this content of text should be there is in " parameter configuration table ", therefore " golf " just becomes the Web page text keyword of this webpage, but the advertising message only gone out according to " golf " this Keywords matching not only comprises the relevant advertisements information of golf automobile, also comprise the relevant advertisements information of golf sports, the advertising message therefore matched and the correlativity of web page contents poor.In addition, if there is not body matter in webpage, be all image or video etc., the number of the Web page text keyword so determined is 0, now can only displaying advertising messages at random, and the correlativity therefore between advertising message and web page contents is very low.
Therefore prior art is when carrying out advertising message and throwing in based on web page contents, the correlativity existed between advertising message and web page contents is lower, the problem that the input precision of advertising message is lower causes the waste of the Internet resources such as storage, calculating, bandwidth.
Prior art is when carrying out the input of advertising message based on web page contents, each Web page text keyword is only comprised in the matching keywords set of match advertisements information, therefore when Web page text keyword accurately can not reflect the subject content of webpage, the advertising message matched and the correlativity of web page contents are just lower, and in the embodiment of the present application one, Web page text keyword is not only comprised in the matching keywords set of match advertisements information, also comprise metamessage keyword, because metamessage keyword determines according to the metamessage of webpage, and the metamessage of webpage has valuable help to the subject content expressing webpage, therefore the coupling of advertising message is carried out according to Web page text keyword and metamessage keyword, go with regard to being equivalent to the metamessage of webpage to be increased in the conjecture of the subject content of webpage, enrich matching keywords set, keyword in matching keywords set can be good at the subject content reflecting webpage, therefore the advertising message matched just better can react web page contents, improve the correlativity between advertising message and web page contents, thus improve the precision of advertising message input, also improve the utilization factor of Internet resources.
Such as, certain automobile information class webpage, the most content of webpage is the picture of automobile, only there is " parameter configuration table " this body matter, only " golf " this content of text should be there is in " parameter configuration table ", therefore " golf " just becomes the Web page text keyword of this webpage, and the html element information of this webpage is as follows:
" automobile, car, sedan-chair runs "/> to <metahttp-equiv=" keywords " content=for golf, golf, gti, golfgti
<metahttp-equiv=" description " content=" golf GTI blog "/>
" automobile " this metamessage keyword can be determined according to above-mentioned html element information, so matching keywords set just at least comprises " golf " and " automobile " these two keywords, therefore the advertising message matched just only comprises the relevant advertisements information of golf automobile, and the relevant advertisements information of golf sports can not be comprised, therefore the correlativity of advertising message and web page contents is higher.
Step 26, determines the comprehensive matching degree between each advertising message and described matching keywords set respectively;
Wherein, can be, but not limited to, by the comprehensive matching degree between following method determination advertising message and matching keywords set, be specially:
For each advertising message, perform following operation respectively: first mated with each advertising message respectively by each keyword in matching keywords set, obtain the matching degree of each advertising message and each keyword, corresponding coupling weighted value is provided with respectively in advance for each keyword, after the matching degree obtaining each advertising message and each keyword, obtain the coupling weighted value of each keyword in matching keywords set, then according to the matching degree of each keyword and each keyword mate weighted value, determine the comprehensive matching degree between this advertising message and matching keywords set.Such as, keyword 1, keyword 2 and keyword 3 is comprised in matching keywords set, the matching degree of advertising message A and keyword 1 is VA1, the matching degree of advertising message A and keyword 2 is VA2, the matching degree of advertising message A and keyword 3 is VA3, the coupling weighted value pre-setting keyword 1 is W1, the coupling weighted value of keyword 2 is W2, and the coupling weighted value of keyword 3 is W3, and the comprehensive matching degree of so advertising message A and matching keywords set is:
VA1×W1+VA2×W2+VA3×W3
Step 27, comprehensive matching degree being met pre-conditioned advertising message renders in described webpage, wherein saidly pre-conditionedly be: comprehensive matching degree is not less than the second defined threshold, or after being sorted by high order on earth according to comprehensive matching degree before a defined amount comprehensive matching degree.
From above-mentioned processing procedure, in the embodiment of the present application technical scheme, first the body matter of the webpage of advertising message to be put is obtained, according to the body matter got, determine each Web page text keyword of this webpage, then the metamessage of this webpage is obtained, according to the metamessage got, determine each metamessage keyword of this webpage, again by each Web page text keyword of determining and each metamessage keyword, form the matching keywords set that advertising message is mated, determine the comprehensive matching degree between each advertising message and described matching keywords set respectively, comprehensive matching degree being met pre-conditioned advertising message renders in described webpage, therefore, matching keywords set in the embodiment of the present application not only comprises Web page text keyword, also comprise the metamessage keyword determined according to the metamessage of webpage, therefore the advertising message gone out according to matching keywords sets match just better can react the subject content of webpage, thus the correlativity that effectively improve between advertising message and web page contents, improve the precision that advertising message is thrown in, and improve the utilization factor of Internet resources.
