The embodiment of the present invention provides a kind of information search method and device, wherein, according at least one got The scope prescribed information of individual keyword, for each keyword at least one keyword, finds out symbol Close scope prescribed information limit in the range of one or more conjunctive words, and according to find each close One or more conjunctive words of keyword carry out information search, obtain limiting positioned at scope prescribed information in the range of Information search result.Wherein conjunctive word includes synonym and/or near synonym.
, can be according to scope prescribed information to each keyword using scheme provided in an embodiment of the present invention One or more conjunctive words are screened, and obtain meeting the conjunctive word of scope prescribed information limited range, And the one or more conjunctive words obtained according to each keyword and screening carry out information search.Therefore, may be used To be screened according to scope prescribed information to conjunctive word, and then it can be carried out when carrying out information search Garbled, more accurate search result.
Below, in order to make it easy to understand, introducing the concept being related in the embodiment of the present invention.
First, keyword and conjunctive word
In information search, it will usually carry out information search, these keywords according to one or more keywords It can be inputted by user, it is also possible to obtained from text.These keywords, which are used for representative, to be searched for Information in main contents.
In the embodiment of the present invention, the conjunctive word of a keyword can include the synonym of the keyword and/or near Adopted word.
Such as, " gardenia also known as cape jasmine, Yellow Fructus Gardeniae ", then can be assumed that the same of gardenia according to this text Adopted word is cape jasmine or Yellow Fructus Gardeniae.For another example, " discrimination " refers to resolution, difference, and " discriminating " refers to by investigating And the property or feature of things are determined, the two similar import, it is believed that " discriminating " is the near of " discrimination " Adopted word.The synonym or near synonym of one word can be called the conjunctive word of this word.
The synonym and/or near synonym of word can over time or the change of the scope of application such as region and it is different. During social development, the words of some words sense over time or the change of the scope of application such as region and become Change, such as：In the Yuan Dynasty, woman servant is synonymous with father, in ancient times, and brother is synonymous with sister；Also some words exist Some region has identical implication, such as in Sichuan province, and people " capsicum " are called " hot pepper ", in Shaanxi Area, people " capsicum " are called " long and thin hot pepper ".
Existing searching method does not account for being applicable for the keyword to be searched for and its synonym and/or near synonym Scope, influences the accuracy of search result.Such as, for " in Sichuan province, people capsicum is called hot pepper, In In Shanxi Area, people capsicum is called long and thin hot pepper " this synonym matched text, when search " Chili Peppers In Sichuan Province, China " When, " Sichuan hot pepper " and " Sichuan long and thin hot pepper " the two search suggestions and corresponding search result can be provided.But It is that due to not accounting for keyword " Sichuan " this scope of application prescribed information in search, thus can give Go out " Sichuan long and thin hot pepper " this search suggestion and corresponding search result, this search suggestion and search result are obvious Required for not being the user scanned for, thus this search suggestion and search result are redundancies, influence The accuracy of search result.
2nd, scope prescribed information
Scope prescribed information refers to that being used in inquiry request shows the limit of the query context of this inquiry request Determine information, such as temporal information or regional information.
When scope prescribed information is temporal information, show inquiry request needs inquiry is the temporal information In the time range that is characterized, the search result that includes the keyword in inquiry request；When scope prescribed information During for regional information, show the inquiry request need inquire about be it is in the territorial scope, comprising inquiry request In keyword search result.
Scope prescribed information can be obtained from inquiry request, can also be from the word of the keyword in inquiry request Obtained in justice.
Alternatively, priority can be set to the mode that above two obtains scope prescribed information.Such as, can be with Set：The priority of the scope prescribed information obtained from inquiry request is higher than to be obtained from the meaning of a word of keyword Scope prescribed information.
The mode of scope prescribed information is obtained from inquiry request can a variety of, and three kinds are only enumerated below from looking into The example that scope prescribed information is obtained in request is ask, actual acquisition modes are not limited to following three kinds：
Scope prescribed information in the keyword inputted in mode one, inquiry request.
Such as, " the Yuan Dynasty " this scope can be obtained from " woman servant's the Yuan Dynasty " this inquiry request and limits letter Breath.
Mode two, by setting the functional module of input range prescribed information obtain scope prescribed information.
Such as, input range prescribed information can be used in inquiry request page setup window or plug-in unit.
Mode three, the typing for carrying out by the representation of agreement Query Information.
Such as, it is to need behind scope prescribed information, colon to be before colon when can arrange input inquiry request The keyword to be inquired about, such as input " Ming Dynasty：During Liu Baiwen ", mark is limited in " Ming Dynasty " this scope Search " Liu Baiwen " this keyword in the time range that information is limited.
The mode of scope prescribed information is obtained from the meaning of a word of keyword to be：Some personalities, ancient books, Historical events etc. is substantially associated with the scope prescribed information such as some times, region, then make when these words When being input to for keyword in inquiry request, these scope prescribed informations can be obtained, the inquiry request is used as In scope prescribed information.For example, when including " Cao Xueqin " in the keyword of input, can be from " Cao This keyword of snow celery " is associated with " Qing Dynasty " this region, so that please as this inquiry by " Qing Dynasty " The scope prescribed information asked.
Alternatively, when scope prescribed information be temporal information or regional information, judge some keyword whether with Temporal information or regional information are associated, can by set a time tag storehouse or region tag library come Realize.
Record and (such as gone through with the time corresponding to personality, ancient books, historical events etc. in time tag storehouse The age that the time of historical event part generation, personality are present) information, when bag in the keyword in inquiry request During containing these personalities, ancient books, historical events, can by the personality in time tag storehouse, ancient books, The corresponding temporal information such as historical events as the inquiry request scope prescribed information.
Record and (such as gone through with the region corresponding to personality, ancient books, historical events etc. in the tag library of region The region of history locale, personality's birth or life) information, when the key in inquiry request In word include these personalities, ancient books, historical events when, can by the personality in the tag library of region, The corresponding regional information such as ancient books, historical events as the inquiry request scope prescribed information.
If in addition, scope prescribed information is regional information, can also pass through the user's asked input inquiry Understood or obtain ground by positioner positioning in IP (Internet Protocol, procotol) address Domain information.
3rd, the scope of application of conjunctive word
Search some keyword conjunctive word when, the conjunctive word might not under any circumstance all with key Word is synonymous, but synonymous with the keyword in some scope of application.Such as, in Sichuan province, people claim Capsicum is hot pepper, then hot pepper is not all synonymous with capsicum in all regions, but only " Sichuan " this It is synonymous with capsicum in one scope of application；For another example, woman servant is synonymous with father in the Yuan Dynasty, then woman servant is not It is all synonymous with father in all dynasties, but it is only synonymous with father in " the Yuan Dynasty " this scope of application.On State the scope of application that " Sichuan " and " the Yuan Dynasty " is conjunctive word.
Alternatively, the scope of application of conjunctive word can be time or region.
4th, conjunctive word marker character
Text in internet or database is analyzed, and then obtains the conjunctive word of some keyword During, conjunctive word marker character is used for marking the incidence relation that the keyword is associated between word.For example, For " gardenia is also known as cape jasmine, Yellow Fructus Gardeniae." this text, searching for the conjunctive word of " gardenia " During, pass through " being also known as " in the text behind " gardenia ", it can be appreciated that after " being also known as " The word in face is the conjunctive word of " gardenia "." being also known as " is a kind of conjunctive word marker character.
Conjunctive word marker character is not limited to a kind of above-mentioned form, and it can be that word can also be symbol.Such as, Exist in the entry of gardenia "【Alias】：Cape jasmine, yellow chicken, yellow sprout, Yellow Fructus Gardeniae, yellow Cape jasmine, mountain Yellow Cape jasmine, beautiful lotus etc.." this text, wherein "【Alias】：" it is also a kind of conjunctive word marker character.
5th, the matching range of conjunctive word marker character in the text
The matching range of conjunctive word marker character in the text is used to mark what conjunctive word was likely to occur in the text Position range.
Such as, for " gardenia is also known as cape jasmine, Yellow Fructus Gardeniae." this matched text, finding conjunctive word After marker character, in addition it is also necessary to know that the conjunctive word of the sphere of action of conjunctive word marker character, i.e. gardenia is likely to occur Position range.By analyzing fullstop last in the text it is recognised that the word after fullstop is no longer Cape jasmine The conjunctive word of son flower, the i.e. matching range of conjunctive word marker character in the text terminates to fullstop.
Fig. 1 shows a kind of network architecture of information search system.As shown in figure 1, information search system bag Include：Server 101, client 102 and memory 103, server 101 can also include processor, Memory and I/O interfaces.
Server 101 passes through processor pair by inquiry request of the I/O interfaces from client 102 The inquiry request of reception is handled, and the search result obtained after processing can be returned into client 102 and entered Row displaying.The programmed instruction stored in the run memory of server 101, is handled inquiry request.This Outside, server 101 can also be by the ephemeral data storage produced during processing inquiry request in memory. Server 101 handle inquiry request when may need access database (such as thesaurus, time tag storehouse, Region tag library etc.) server 101 memory of itself is can come from, it can be from the memory of outside 103。

Wherein, step S805 and step S806 can be considered an abovementioned steps S304 example.
S807：Original keyword is substituted using the synonym of acquisition, and the additional phase after the completion of replacement The temporal information answered, forms new crucial phrase；
Such as：The new keywords group in " woman servant's the Yuan Dynasty " is " woman servant member ", " father's member ", " father's the Yuan Dynasty ", " mother's member ", " mother's the Yuan Dynasty " etc..
Here the alternative of synonym can be using " full combination " method, the Chinese key group of such as input " Chinese word 2 " of Chinese word 1, Chinese word 1 has 5 synonyms, and Chinese word 2 has 4 synonyms, The new keywords group then formed is 29 kinds (29=6*5-1).Wherein, " Chinese is not included in new keywords group This crucial phrase of the Chinese word 2 " of word 1.
Particular/special requirement is not made to the replacement method of synonym in embodiments herein, as long as can realize synonymous The replacement of word.
Wherein, step S807 can be considered in abovementioned steps S304, " will when there is at least two keywords It is combined between the conjunctive word of different keywords at least two keywords found, and will at least Partial key word in two keywords and be combined between the conjunctive word of remaining keyword found " One example.
S808：New keywords group with time or regional information is handled, search suggestion is formed；
In step S808, foregoing can be considered to the new keywords group progress processing with time or regional information In step S304, it will be carried out between the conjunctive word of the different keywords at least two keywords found Combination, and by the Partial key word at least two keywords and the conjunctive word of remaining keyword found Between be combined after, one of process of the scope of application of the combination is determined to each obtained combination Example.
Carry out logicality analysis to the new keywords group of acquisition first, such as " Chinese word 2 " of Chinese word 1 it is new Crucial phrase is " synonym 1-1 synonym 2-1 " then analyze synonym 1-1 and synonym 2-1 time It is new crucial if overlapped, then it is assumed that it is an effective new keywords group or whether regional information overlaps The temporal information of phrase is the common factor of synonym 1-1 and synonym 2-1 temporal information, new keywords group The common factor of regional information synonym 1-1 and synonym 2-1 regional information.If synonym 1-1 and synonymous Word 2-1 temporal information or regional information is misaligned, then it is assumed that it is an invalid new keywords group.
Wherein, new keywords group is " by least two keywords found in abovementioned steps S304 Different keywords conjunctive word between be combined, and by the Partial key word at least two keywords Be combined between the conjunctive word of remaining keyword found " after an obtained example of combination, newly The temporal information or regional information of crucial phrase are the " scope of application of the combination in abovementioned steps S304 Information " example.
After effective new keywords group is obtained, according to the formation search suggestion of effective new keywords group.Searching In Suo Jianyi forming process, effective new keywords group can be ranked up, according to setting output wherein It is one or more, formed search suggestion.The degree of correlation of current new keywords group and former crucial phrase is such as evaluated, Arranged according to descending, extract the formation search suggestion of the first two new keywords group.Here the evaluation of the degree of correlation can be with Different modes are taken, are such as ranked up by the length of time span or the size of region of new keywords group, Or be ranked up according to the number of the historical search number of times of new keywords group.It is right in embodiments of the invention Sort method is not construed as limiting.
Such as：In new keywords group " woman servant's member ", " father's member ", " father's the Yuan Dynasty ", " mother's member " is " female It may be selected when search suggestion is chosen in close the Yuan Dynasty " etc. containing a pair of minimum crucial phrases of time range, it is such as " female Parent " and the synonymy of " woman servant " are not limited to the Yuan Dynasty, and define the Yuan Dynasty in the keyword this time searched for This scope prescribed information, therefore prioritizing selection contains the search suggestion of " father ", " mother " then conduct Not preferred search suggestion；And " the Yuan Dynasty " can accurately more state temporal information than " member ", thus it is excellent First search of the selection containing " the Yuan Dynasty " advises that " member " then advises as not preferred search.Ultimately form " father's the Yuan Dynasty " this search is advised.
It is alternatively possible to be built obtaining effective new keywords group and forming search according to these new keywords groups The search suggestion of formation is shown after view, the exhibition method of search suggestion may be referred to Fig. 4 and Fig. 5 Shown exhibition method.
S809：Judge whether to perform the search suggestion formed in step S808；If so, step S811 is performed, If it is not, performing step S810；
