In practical application, due to carrying out words cutting to web page title using participle cutting method, and to the words of cutting Meaningless word removal is carried out, cannot be removed effectively information unrelated to user in web page title.For example, web page title " upper Sohu, See the Olympic Games " after words cutting, the removal of meaningless word and words combination, the web page title extracted, which remains as, " above to be searched Fox sees the Olympic Games ", and for a user, "upper" and " seeing the Olympic Games " they may be the information useless to user, so that limited clear The useful information amount provided a user of looking in device display area is reduced, and reduces the business experience of user;For another example for webpage Title " welcomes access Sohu ", after existing method extracts web page title, obtains truncated web page title and remains as " welcoming access Sohu ", and wherein, " welcoming access " is descriptive expression, cannot provide the information useful to user, in this way, by Some descriptive expressions are contained in truncated web page title, on the one hand, so that truncated web page title is not able to satisfy browsing Device display area requires, on the other hand, but also the useful information that truncated web page title is supplied to user is less, and web page title De-redundancy effect is poor.Preferably, propose that one kind retains as far as possible each web page title the useful letter of title in the embodiment of the present invention Breath a kind of web page title truncate technology, that is, the method for obtaining truncated web page title, by establish webpage white list library and/ Or, Page template library, and/or, sew before and after web page title identification library, and/or, truncate general rule, have to web page title With truncation, it is allowed to keyword or crucial phrase comprising more refining, and removes the information unrelated with user, to meet browsing Device display area requires, and provides a user more useful information.

Fig. 1 shows the method flow signal that the embodiment of the present invention obtains truncated web page title.Referring to Fig. 1, the process Include:

Step 101, it obtains webpage URL information to be truncated and is somebody's turn to do webpage unified resource positioning to be truncated Accord with the web page title of information MAP;

In this step, truncated technology is carried out only for web page title relative to existing, in the embodiment of the present invention, for reality Existing more efficiently web page title truncates and the matching embodiment of the present invention proposes webpage white list library, and/or, Page template Library, and/or, identification library technology is sewed before and after web page title, when obtaining to web page title, it is also necessary to obtain and simultaneously utilize the net Page URL information, and as alternative embodiment, unlike the prior art, in the embodiment of the present invention, wait cut Short web page title can not be the invalid title of representation page subject information for empty or url etc..

This step specifically includes:

It receives and carries out the truncated request of web page title;

In this step, user is during browsing webpage, if it is determined that needs to collect the webpage, then in the net The display interface of page is added to collection submenu by clicking in collection drop-down menu, and triggering carries out web page title and cuts Short, which extracts the web page title of user browsing, that is, web page title to be truncated, by the web page title of extraction and The webpage URL information (webpage URL information to be truncated), which is encapsulated in, carries out web page title truncation Request in, to server send;Alternatively, user need to the web page title (web page title to be truncated) stored in collection into Row optimization, then by clicking the renaming submenu arranged in collection drop-down menu, triggering carries out web page title truncation, user It can choose and need to carry out truncated web page title, the web page title and the webpage that web browser chooses the user are unified Resource Locator Information encapsulation is sent in carrying out the truncated request of web page title to server, wherein if user, which chooses, to be had Multiple web page titles, then in carrying out the truncated request of web page title, each web page title and the webpage uniform resource locator Information forms mapping relations.

Parsing carries out the truncated request of web page title, obtains web page title to be truncated and is somebody's turn to do webpage unified resource to be truncated Locator information.

In this step, server is receiving the progress truncated request of web page title, is asked by decapsulating and parsing this It asks, the web page title and the webpage URL information carried in available request.

Step 102, pre-set web page title matching library is inquired, webpage URL information to be truncated is obtained Corresponding matching rule handles the web page title to be truncated according to obtained matching rule, obtains truncated webpage Title;The web page title matching library include: webpage white list library, and/or, web page title template library, and/or, web page title Front and back sew identification library, and/or, truncate general rule, wherein

The corresponding truncated web page title of webpage URL information is stored in webpage white list library;

It is stored with the corresponding canonical of webpage URL information in web page title template library and truncates rule;

Sew suffix list and/or front and back before being stored with web page title in identification library before and after web page title and sews recognition rule.Its In, it is setting for carrying out the term frequency-inverse document word that identification is sewed in front and back to web page title that recognition rule is sewed before and after web page title Frequency calculative strategy, it is subsequent to be described in detail again.

In this step, as preferred embodiment, web page title matching library can also be loaded into caching in advance.

In the embodiment of the present invention, if being stored with webpage white list library, web page title template library in web page title matching library And sew identification library before and after web page title, since webpage white list storehouse matching required time is short, it can effectively filter and be not included in Web page title in webpage white list library reduces subsequent processing;And it is longer the time required to being matched with web page title template library, And sew longest the time required to identification library is matched with web page title front and back.Thus, if necessary to be carried out using triplicity Slug truncates, preferably, the matching rule used is sequentially are as follows: before webpage white list library, web page title template library, web page title Suffix identifies library.

Generating webpage white list library includes:

A11 extracts each webpage URL information for including in user's collection and the positioning of webpage unified resource Accord with the web page title of information MAP;

In this step, from user's collection comprising web page title (web page storage title), the net of user setting is extracted Page head and webpage URL information.

In the embodiment of the present invention, since user is when carrying out web page access using sogou browser, sogou browser can be deposited The web page access record of user is stored up, for example, user is the web page title and the webpage URL information of webpage setting, server is logical The web page storage folder data extracted in sogou browser are crossed, available a large amount of webpage URL information and each user are to webpage The web page title of URL information setting.Wherein, webpage URL information and web page title constitute mapping relations (title to), different use For same webpage URL information, the web page title of setting can be different at family.Thus, same webpage URL information may be mapped with respectively A large amount of different web pages titles that the webpage URL information is arranged in user.

A12 obtains all webpages of web page resources locator information mapping for each web page resources locator information Title, and, count the corresponding number of users of each web page title of web page resources locator information mapping;

In this step, since the difference of user thus for each webpage URL information, is mapped with different webpage marks Topic.In the embodiment of the present invention, for each webpage URL information, each web page title of webpage URL information mapping is counted respectively Corresponding number of users.For example, for webpage URL information:www.sohu.com, the web page title of mapping includes: that " upper Sohu, sees The Olympic Games ", " welcoming access Sohu ", " Sohu " and " Sohu official website ", wherein by statistics, " upper Sohu, see the Olympic Games " is corresponding Number of users is 10,000, that is, has 10,000 users by webpage URL information:www.sohu.comThe web page title of mapping is set as " above searching Fox sees the Olympic Games ", " welcoming access Sohu " corresponding number of users is 1.5 ten thousand, and " Sohu " corresponding number of users is 50,000, " Sohu official The corresponding number of users of net " is 2.5 ten thousand.

A13 calculates the corresponding number of users of web page title and web page title applied to pre-set webpage white list Strategy obtains the web page title weighted value;

In this step, as alternative embodiment, webpage white list calculative strategy can be the calculative strategy according to number of users, Then web page title weighted value is user's numerical value.As described in step A12, according to the calculative strategy of number of users, web page title " is above searched Fox sees the Olympic Games " corresponding web page title weighted value is 10,000, " welcoming access Sohu " corresponding web page title weighted value is 1.5 Ten thousand, " Sohu " corresponding web page title weighted value is 50,000, and " Sohu official website " corresponding web page title weighted value is 2.5 ten thousand.

Certainly, as another alternative embodiment, it is also contemplated that the field weight of user's fields into practical application, For the user in a certain field, it is accurate that the user in the field names the web page title that webpage URL information maps Property should be greater than the accuracy of the web page title name that user in other non-fields maps same webpage URL information, i.e., should The web page title name that user in field maps webpage URL information is available to be more widely applied and popularizes.For example, It, should be big to the accuracy of the web page title name of machinery field webpage URL information mapping for the user of a certain machinery field In the accuracy for the web page title name that other on-mechanical field users map the webpage URL information.Thus, webpage white list Calculative strategy can be the calculative strategy according to pre-set user's fields weight, in this way, by being in advance each use Each field weight is respectively set in family, for example, it is 0.5 that its machinery field weight, which can be set, for a certain field user, electricity neck Domain weight is 0.3, and communications field weight is 0.2 etc..About field belonging to user is determined, the feature of user tag can be passed through Match to obtain, is well-known technique, detailed description is omitted here.In this way, by the corresponding number of users of web page title and web page title application In pre-set webpage white list calculative strategy, obtaining the web page title weighted value includes:

B11 extracts the Feature Words for including in the web page title of webpage URL information mapping, special with pre-set each field Sign dictionary is matched, and determines field belonging to the webpage URL information;

In this step, for example, for webpage URL information, randomly select a web page title " welcoming access Sohu ", mention The Feature Words taken are Sohu, if including Feature Words Sohu in the feature dictionary of the communications field, then belonging to the web page title Field is the communications field.

B12 obtains the mapping of webpage URL information according to being in advance the respectively arranged each field weight of each user respectively Field weight of the user that each web page title includes in the determining webpage URL information fields;

In this step, for " upper Sohu, see the Olympic Games ", wherein in 10,000 users, have 0.2 general-purpose family in the communications field Field weight be 0.2, have 0.3 general-purpose family the communications field field weight be 0.3, have 0.1 general-purpose family in the communications field Field weight is 0.6, and having field weight of the 0.4 general-purpose family in the communications field is 0.9.For webpage URL information:www.sohu.comOther web page titles of mapping are counted according to method identical with this.

B13, the number of users for including by web page title and user are in the field of the determining webpage URL information fields Weight is applied to pre-set weight calculation formula, obtains web page title weighted value.

In this step, weight calculation formula can be total weight calculation formula, be also possible to relative weighting calculation formula.Its In, total weight calculation formula is as follows:

In formula,

XiFor i-th of web page title weighted value, wherein i is natural number;

Ui,jFor corresponding j-th of the user of i-th of web page title;

ξi,jFor corresponding j-th of the user of i-th of web page title the web page title fields field weight;

K is the corresponding total number of users of i-th of web page title, and K is natural number.

Relative weighting calculation formula is as follows:

As other alternative embodiments, web page title priority coefficient can also be set for each web page title in advance, and It is combined into the field weight calculation web page title weighted value of the user setting of web page title mapping, i.e. webpage white list calculative strategy It can be the calculative strategy according to pre-set user's fields weight combination web page title priority coefficient.This method into One step includes:

Obtained web page title weighted value is multiplied with web page title priority coefficient, the web page title as final output Weighted value.

In this step, for total weight calculation formula, the web page title weighted value for calculating final output is as follows:

In formula,

ψiFor i-th of web page title priority coefficient.

In the embodiment of the present invention, web page title priority coefficient can be arranged by manual type.For example, by obtaining search dog Corresponding web page title priority coefficient is arranged in each web page title in browser, respectively each web page title.

A14 chooses the corresponding web page title of maximum web page title weighted value, by webpage in same webpage URL information The web page title that URL information and the web page title of selection are mapped as webpage URL information is placed in the webpage white list library of setting In.

In this step, for same webpage URL information, each web page title weight of webpage URL information mapping is calculated After value, the corresponding web page title of maximum web page title weighted value is chosen, is mapped as webpage URL information in webpage white list library Web page title.Wherein, web page title weighted value includes web page title maximum always weighted value and web page title maximum relative weight value, The web page title that the maximum total corresponding web page title of weighted value of web page title is mapped as the webpage URL information can be chosen;Or Person chooses the web page title that the corresponding web page title of web page title maximum relative weight value is mapped as the webpage URL information.

As alternative embodiment, web page title weighted value can also be arranged by size in same webpage URL information Sequence, chooses the corresponding web page title of web page title weighted value of sequence top N, and each webpage URL information maps N number of webpage mark Topic, and N number of web page title that webpage URL information is mapped is placed in the white list library of setting, wherein N is natural number.I.e. in net In page white list library, each webpage URL information is mapped with N number of web page title, wherein N can be determine according to actual needs.

In practical application, since the web page title mapped by webpage URL information obtained by the above method is according to user Behavior is selected, and the web page title of the webpage URL information mapping in user's collection may not can accurately reflect webpage Title, and in the web page navigation data that each navigation website provides, due to being to have carried out height to webpage by technical professional Degree is summarized, thus, the web page title provided comparatively refines, and the useful information for including is more.Thus, the embodiment of the present invention In, after generating webpage white list library, further, this method can also include:

C11 obtains web page navigation data, extracts the webpage URL information for including in web page navigation data and webpage URL The web page title of information MAP;

In this step, web page navigation data can be grabbed from each navigation website, and to webpage by way of web crawlers Navigation data is parsed, and the web page title of webpage URL information and the mapping of webpage URL information is therefrom extracted.About crawl net Page navigation data, extracts web page title and webpage URL information is well-known technique, detailed description is omitted here.

C12 traverses each webpage URL information of extraction, believes in query webpage white list library with the presence or absence of webpage URL Breath, if it does not, white list library is written into the web page title that the webpage URL information and the webpage URL information map, if In the presence of, from the web page title of extraction and webpage white list library, the web page title of webpage URL information mapping is obtained respectively, The web page title that the webpage URL information maps in more new web page white list library is determined whether after being compared.

In the embodiment of the present invention, since the webpage URL information quantity provided in web page navigation data is relatively limited, i.e., cannot All webpage URL informations are covered on a large scale, thus, using this method as a useful supplement in webpage white list library.Pass through The web page navigation data of each navigation website are grabbed, the web page title of webpage URL information and webpage URL information mapping is extracted, and It, will be from the webpage in webpage white list library in the web page title stored and the Web side navigation data of crawl according to webpage URL information Title is compared, to choose more accurate web page title of expressing the meaning, i.e., if the webpage mark stored in webpage white list library Topic is expressed the meaning more accurate, then is not dealt with, if the web page title for the webpage URL information mapping extracted from web page navigation data It expresses the meaning more accurate, then the web page title stored in webpage white list library is updated.

So far, the process for generating webpage white list library terminates.

Generating web page title template library includes:

Sort out strategy in advance for the web page title setting of webpage URL information mapping, and is set for the web page title of each classification Set corresponding regularity.

It,, can be with from a large amount of web page title data although the web page title quantity of each website is various in this step Web page title is sorted out according to pre-set classification strategy, wherein classification strategy can be rich according to social category, technology The classification strategy of objective class etc., that is to say, that web page title is classified as social category web page title, Tech blog class web page title Deng.And corresponding regularity is set for the web page title of each classification, form web page title template.

In subsequent, after sorting out to web page title, in the web page title of classification, the corresponding canonical of the classification is used Rule intercepts the web page title of classification, and truncated web page title can be obtained.For example, in web page title template library, Social category web page title and the corresponding regularity of Tech blog class web page title is respectively set in advance, in this way, by webpage It, can be by the web page title of each classification after title is classified as social category web page title or Tech blog class web page title It is intercepted according to pre-set corresponding to the regularity accordingly sorted out, to obtain corresponding truncated web page title.

About for the web page title of each classification, corresponding regularity is set, it can be by being carried out to the web page title of classification Data mining obtains, detailed description is omitted here.

In the embodiment of the present invention, due at the ending of each web page title, often containing " homepage ", " it is reported that ", it is " outer Matchmaker ", " hot spot " etc. be used for keep web page title eye-catching preceding suffix information, or indicate web page title structure and with web page title The unrelated preceding suffix information of theme.In order to remove the preceding suffix information of web page title, aforementioned regularity or white list are used Information filtering is sewed in library process before and after carrying out is relatively complicated.Thus, in the embodiment of the present invention, can use title library (storage The web page title of webpage URL information mapping) mass data analysis is carried out, periodic data excavation is carried out using TFIDF method, thus Suffix information before grabbing out.

Sewing identification library before and after generation web page title includes:

Obtain the web page title of webpage URL information mapping and storage in user's collection;

It is arranged for carrying out term frequency-inverse document word frequency (TF-IDF, the Term that identification is sewed in front and back to web page title Frequency-Inverse Document Frequency) calculative strategy.

In the embodiment of the present invention, TF-IDF is a kind of common weighted statistical method for information retrieval.Wherein, word frequency is used To assess a words for the weight of a copy of it document in a document library (file set or corpus), the weight of words with The directly proportional increase of number that occurs in document library of the words, while the frequency occurred in document library with the words is at anti- Than decline;Inverse document word frequency is the measurement of a words general importance.

The weight calculation formula of TF are as follows:

In formula,

TF is word frequency weight;

PwThe number in document library is appeared in for word (words) w;

P is document library length, that is, the words total quantity for including.

The weight calculation formula of IDF are as follows:

In formula,

IDF is inverse document word frequency weight;

DwFor individual (document) sum in sample (document library, file set or corpus) containing words w;

D is total sample number, i.e., total number of files.

If IDF value is smaller, indicate that document more in sample includes the words, the information content which includes is got over It is few;If IDF value is bigger, indicate that document only fewer in sample includes the words, the information content which includes is bigger.

In conjunction with word frequency and inverse document word frequency, available term frequency-inverse document word frequency:

In formula, WeightwFor the TF-IDF weight of words w.

If TF-IDF weight value is bigger, the indicative better of the words is indicated.

The truncated web page title of acquisition is described in detail again below.

In the embodiment of the present invention, if web page title matching library includes webpage white list library, pre-set net is inquired Page head matching library obtains the corresponding matching rule of webpage URL information to be truncated, and is advised according to obtained matching Then the web page title to be truncated is handled, obtaining truncated web page title includes:

Query webpage white list library obtains the web page title of webpage URL information mapping to be truncated, and will Obtained web page title is as truncated web page title.

In this step, for not storing the feelings of webpage URL information to be truncated in webpage white list library Shape can carry out truncation processing to web page title according to the prior art, and details are not described herein.

If web page title matching library includes web page title template library, pre-set web page title matching library is inquired, The corresponding matching rule of webpage URL information to be truncated is obtained, according to obtained matching rule to described wait truncate Web page title is handled, and is obtained truncated web page title and is included:

D11 extracts the naming rule of the web page title of webpage URL information mapping to be truncated, by the naming rule of extraction With pre-set classification strategy, classification belonging to the web page title of the webpage URL information mapping to be truncated is obtained;

In this step, classification belonging to the web page title can be distinguished by the naming rule of analysis web page title.About Web page title is carried out to be classified as well-known technique, detailed description is omitted here.

As alternative embodiment, if the web page title of webpage URL information mapping is invalid, i.e., web page title completely cannot be anti- Web page contents are answered, for example, empty, that is, not including in any only includes perhaps symbol, then can return to the domain of the webpage URL information Name is used as truncated web page title.

D12, query webpage title template library obtain belonging to the web page title that the webpage URL information to be truncated maps Sort out corresponding regularity;

In this step, if affiliated is classified as after the web page title for treating truncation webpage URL information mapping is sorted out Social category web page title is read as the regularity of social category web page title setting then from web page title template library.

D13 treats the web page title progress canonical processing for truncating the mapping of webpage URL information using the regularity of acquisition, Obtain truncated web page title.

If web page title matching library includes that identification library is sewed in web page title front and back, pre-set web page title is inquired With library, the corresponding matching rule of webpage URL information to be truncated is obtained, according to obtained matching rule to described Web page title to be truncated is handled, and is obtained truncated web page title and is included:

E11 obtains the web page title of webpage URL information mapping to be truncated, according to pre-set fractionation strategy to acquisition Web page title split, obtain one or more webpage subtitles;

In this step, since when collecting to web page title, each component part of web page title has certain spy Point, for example, prefix (or descriptive expression), title text, one or more suffix have been generally comprised, and by web page title The estimation of each component part is analyzed, and can be distinguished by some specific punctuation marks;Furthermore for title text, it is The information useful to user can be used as whole provide a user.

As a result, in the embodiment of the present invention, splitting strategy be can be according to the pre-set punctuate for including in web page title Symbol is split.For example, pre-set punctuation mark can be _ ,-,-,+, &, # ...:,, |:, ┊,‖,;,,.,, s ,-,-, etc..If in web page title including any of the above-described pre-set symbol, by the webpage Title is split from the symbol.

E12, in conjunction with the web page title for sewing the webpage URL information mapping stored in identification library before and after web page title, for every It is every to calculate this using the term frequency-inverse document word frequency calculative strategy being arranged in identification library is sewed before and after web page title for one webpage subtitle The term frequency-inverse document word frequency value of one webpage subtitle;

Step 314, judge in truncated web page title whether comprising being included content, if so, execute step 315, Otherwise, step 316 is executed;

In this step, included content refers to include content in the symbols such as punctuation marks used to enclose the title, bracket.

Step 315, using included content as truncated title content, and terminate process;

Step 316, truncated web page title is treated using pre-set first group of punctuation mark carry out cutting;

Step 317, the fragment length of cutting is judged whether there is no more than pre-set segment threshold value, if so, executing Step 318, otherwise, step 321 is executed;

Step 318, it for the segment of each cutting no more than pre-set segment threshold value, removes in the segment and commonly uses Phrase, judges whether the fragment length for removing common phrases is not more than pre-set web page title length threshold, if so, holding Otherwise row step 319 executes step 320;

Step 319, the segment after returning to removal common phrases as truncated web page title and terminates process;

Step 320, cutting is carried out using segment of the pre-set second group of punctuation mark to removal common phrases, returned Execute step 317;

Step 321, since described to truncated web page title initial position, the character of intercepting page length for heading threshold value String is used as truncated web page title.

In the embodiment of the present invention, step 314 to step 321 is truncated to be treated using pre-set truncation general rule Web page title carries out truncation processing.For example, for being that " trivial games, 4399 trivial games, trivial games are big to truncated web page title Entirely, the game of double trivial games complete works-www.4399.com Largest In China ", webpage URL information be " http: // Www.4399.com/ sogou " is calculated according to above-mentioned truncation general rule, and the truncated web page title of acquisition is " 4399 Trivial games ".
