Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the method for obtaining navigation enquiry words that the embodiment of the invention provides may further comprise the steps:
S101: obtain the related data sources that comprises text;
S102: based on the navigation keyword that presets the text in the related data sources is analyzed, obtained navigation enquiry words.
Wherein, as long as described related data sources comprises text, therefore can obtain Data Source very widely, for example, can be each webpage in the internet, and the text in the then described related data sources is the text that presents on each webpage.Can grasp and the text that presents on the webpage is obtained in the analysis of front end page elements by the page, include but not limited to the title, text summary, link text of webpage etc.Certainly, described related data sources can also comprise user's search engine logs, and at this moment, the text in the related data sources can also comprise the query word in the search engine logs.
Core of the present invention is, at the defective of prior art scheme, obtains navigation enquiry words all sidedly by obtaining the more data source.Be convenient and describe, below be that example describes in detail method of the present invention all with this data source of each webpage in the internet.
The present invention considers has some can have suffix such as " website ", " homepage " in the text that presents on each webpage in the internet, for example, and " Rockets's Chinese website ", " Sohu's homepage " or the like.With these speech is that the speech of suffix is likely navigation enquiry words, and the present invention is called the navigation suffix with such suffix, is the speech of suffix by excavating with the navigation suffix, can obtain a large amount of navigation enquiry words.Therefore, the present invention is based on that the navigation keyword that presets analyzes the text that presents on each webpage, described navigation keyword can be described navigation suffix, includes but not limited to " homepage ", " homepage ", " door ", " website ", " official website " or the like.
Wherein, based on the navigation keyword that presets the text that presents on described each webpage is analyzed, the method for obtaining navigation enquiry words has a lot, at length introduces below.
Embodiment one, can utilize the regular expression method to analyze.At first stipulate the suffix that navigates a series ofly, can include but not limited to previously described " homepage ", " homepage ", " door ", " website ", " official website " or the like, with regular expression it is organized then.Need to prove, regular expression is the formula that goes to mate a class character string with certain pattern, and this regular expression can be supported widely by various text edit softwares, class libraries (as the tools.h++ of Rogue Wave), wscript.exe (as awk/grep/sed).
Some navigation suffix may be " official website ", " Chinese network ", " personal website " etc., for example " official website of Asus ", in the embodiment of the invention, regard such navigation suffix as the complex navigation suffix, the suffix that is navigation enquiry words may be the combination of two even a plurality of navigation suffix, so the employed regular expression of the embodiment of the invention can be:
" ([.]+?) (and?: official | Chinese | the individual) * (?: homepage | homepage | the website | net | door | the official website)+"
This regular expression can mate with any literal initial, and zero or several " official " or " Chinese " or " individual " are contained in the centre, with the character string of " homepage " " homepage " " website " " net " " door " speech such as " official websites " ending.Form is more flexible, has stronger adaptability, can mate " official website of Asus " and " the refreshing Chinese network that rises in east " compound situation of a plurality of like this navigation suffix.
When mating by above-mentioned regular expression, need carry out at each independent sentence, and the text that presents in the common webpage may be sectional literal, therefore, before this regular expression of use mates, the processing of the text that presents in the webpage need being made pauses in reading unpunctuated ancient writings.Can carry out according to the punctuate identifier that presets during punctuate, wherein, the punctuate identifier can be space, punctuation mark, paragraph sign etc.At first, the whole text that scanning presents in the webpage just disconnects when above-mentioned identifier occurring, finally can obtain a series of short sentences that no longer comprise the punctuate identifier, just independent sentence.And then in each short sentence, search the character string that is complementary with above-mentioned regular expression, and last, just the character string that is complementary that obtains can be defined as navigation enquiry words.
Embodiment two, can directly utilize described navigation keyword that the text that presents on each webpage is analyzed, equally, described navigation keyword can include but not limited to " homepage ", " homepage ", " door ", " website ", " official website ", " official website ", " personal website ", " Chinese network ", or the like.Can at first judge whether comprise above-mentioned navigation keyword in the text that presents on each webpage,, then the character string between first information separator before navigate at this keyword and this navigation keyword can be defined as navigation enquiry words if exist.
Wherein said information separator can be space character, segmentation symbol, and some specific punctuates, and is as follows:
，。；—：、/.！-
For example, the text original text that presents on the webpage for " ... find after opening Sohu today; Sohu's homepage has increased the scroll box that represents Olympic Games latest news ... ", as seen, the described navigation keyword that occurs in this section words is " homepage ", so " Sohu " between ", " of " homepage " is preceding and front is defined as navigation enquiry words.
According to the method described above the text that presents on all webpages in the internet is all handled one time, can get access to a large amount of navigation enquiry words, but may comprise some noises in the navigation enquiry words that gets access to, for example, may " how at search dog " such character string be defined as navigation enquiry words, even also may " have ", " other " etc. be defined as navigation enquiry words, therefore, in a preferred embodiment of the invention, can also comprise the step that the navigation enquiry words that gets access to is filtered.The method of specifically filtering can be varied, can adopt following two kinds of preferred modes in the embodiment of the invention:
(1) because when obtaining navigation enquiry words in the text that all webpages from the internet present, what can duplicate unavoidably gets access to same navigation enquiry words, therefore, can utilize these characteristics as the foundation of filtering navigation enquiry words.Can carry out in such a way: the number of times that each navigation enquiry words that record gets access to occurs, if the number of times that certain navigation enquiry words occurs is less (for example, less than the threshold value that presets), then this navigation enquiry words can be regarded as the accidental noise that occurs, and with its filtering.
Wherein, can safeguard a parameter, be used for preserving the number of times of its appearance for the navigation enquiry words that newly gets access to; When getting access to this navigation enquiry words, all this parameter is added one at every turn, finally can obtain the total degree that each navigation enquiry words occurs.
(2) in actual applications, it is many really that some is confirmed as the number of times that the character string of navigation enquiry words may occur, but in fact these character strings still can not be regarded navigation enquiry words as, for example: and " having ", " other ", " some ", " my company ", or the like.For this situation, these speech can be set in advance to filtering keyword, if being above-mentioned these just, the navigation enquiry words that gets access to filters keyword, then this navigation enquiry words can be considered as noise, and with its filtering.
From above analysis as seen, the method of obtaining navigation enquiry words that the embodiment of the invention provides is based on that text analyzes, and navigation keyword by presetting, only need get final product text analysis, therefore, from search engine logs, obtain the method for navigation enquiry words, reduced requirement data source with respect to prior art, can obtain Data Source widely, help obtaining more all sidedly navigation enquiry words; On the other hand, the corresponding relation that need not equally to consider text and network address to prior art (for example, when prior art gets access to user's query word in search engine logs, need also to know that this user is behind this query word of input, finally selected which network address, can judge whether this query word is the navigation speech), therefore realize simple.
By above-mentioned filter method, can improve the accuracy of obtaining navigation enquiry words, but still might there be some noises in the navigation enquiry words after filtering, for this reason, in a preferred embodiment of the invention, can also comprise the step that the navigation enquiry words that gets access to is further verified: the navigation enquiry words that gets access to is sent to how tame search engine as searching key word search for, whether first of judging search engine search results be consistent, if it is consistent, prove its navigation enquiry words really, and the primary network address of each search engine search results can be defined as the network address of this navigation enquiry words correspondence.If first of each search engine search results is inconsistent, then regard this navigation enquiry words as noise, and with its filtering.
In order to understand the method for obtaining navigation enquiry words that the embodiment of the invention provides better, at length introduce below by concrete example.
For example, following several sections words are arranged on internet web page:
" find after opening Sohu today that Sohu's homepage has increased the scroll box that represents Olympic Games latest news, the online friend can understand the Olympic Games latest news very first time.”
" Chen Guan reopens uncommon website Shu Qi blog tide shop new product and is rushed to purchase "
" how at the lyrics of search dog website download song? the master-hand gives advice! Other website not all right.”
Can utilize the described regular expression of preamble that above-mentioned text is analyzed, at first, utilize punctuation mark, space that above-mentioned urtext is made pauses in reading unpunctuated ancient writings, can obtain following short sentence:
" find after opening Sohu today "
" Sohu's homepage has increased the scroll box that represents Olympic Games latest news "
" online friend can understand the Olympic Games latest news very first time "
" Chen Guan is uncommon, and the Shu Qi blog is reopened in the website "
" damp shop new product is rushed to purchase "
The lyrics of search dog website download song " how "
" master-hand gives advice "
" other website not all right "
Use described regular expression that each short sentence is mated, can obtain following navigation enquiry words:
" Sohu ", " Chen Guanxi ", " how at search dog ", " other ".
More than three navigation enquiry words all occurred once.Use the same method the text that presents on all webpages in the internet is all handled one time, and write down the number of times that each navigation enquiry words occurs.For example:
" Sohu " occurs 19824 times; " Chen Guanxi " occurs 5724 times; " how to remove search dog " and occur 2 times; " other " occurs 24586 times.
Wherein, the number of times that " how removing search dog " occurs is too low, therefore is counted as noise and by filtering; " other " is in the filtration keyword that presets, and therefore, also is counted as noise and by filtering.
Then, search " Sohu " on search dog and these two search engines of Baidu, first of Search Results all is www.sohu.com, thinks that then " Sohu " is navigation enquiry words, and its corresponding target network address is www.sohu.com.
Search " Chen Guanxi " on search dog and these two search engines of Baidu equally, first of the Search Results of search dog is ent.sina.com.cn/s/h/f/chengx.html; First of the Search Results of Baidu is yule.bai du.com/zt/star/yanzhanmen/.Both are inconsistent, thus both think that " Chen Guanxi " is not navigation enquiry words, and with its filtering.
