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.
With reference to Fig. 1, be the process flow diagram of a kind of information retrieval method based on search engine of the present invention, may further comprise the steps:
The shell script of step 101, triggering local program or searched page;
Show instant result in step 104, the prompt column on current searched page.
When using search engine, the user is by clicking search column or using other triggering modes can trigger the shell script of local program or searched page, in case the user begins input, this local program or shell script will monitoring user input equipment, such as keyboard, handwriting pad etc., as long as monitor the input of non-control character or preset key, this local program or shell script can send to search server with this input information immediately, search server mates this input information in instant result database, if corresponding instant result is arranged then should instant result return to local program or shell script, and show in the prompt column on current page.For example, the user is in search column input " Tsing-Hua University ", the input that the shell script of local program or searched page monitors the user is just mated the search server that input information " Tsing-Hua University " sends to search engine, it is the homepage of Tsing-Hua University that search server matches corresponding instant result at instant result database, just shows the network address of Tsing-Hua University in the prompt column of current page
" http://www.tsinghua.edu.cn "If this Search Results meets user's search purpose, if the user in prompt column by select to determine directly to visit the website of Tsing-Hua University by enter key, click or alternate manner; If this Search Results does not meet user's search purpose, the user then not be used in and selects in the prompt column to determine, selects search operation can obtain other Search Results after input is finished.Certainly, for how carrying out search operation under the situation that does not meet the user search purpose in mentioned above searching results, get final product according to the search operation that generally uses now, the present invention does not need this to be limited.
Need to prove that preferred, the instant result who shows in prompt column is meant entity information, entity information comprises entity title and entity network address, and entity is meant object or the notion that is of practical significance in actual life.Search server mates at instant result database according to user's input information, often can match mass data, search server is according to predetermined conditions,, the frequency of occurrences the most high conditional filtering the highest such as clicking rate goes out entity information, and it is returned local program or shell script as the instant result corresponding with this input information.
Wherein, screening conditions can be provided with according to demand voluntarily by the service provider, such as the search service provider that the bid ranking service is provided, screening conditions can be made as the highest entity information of bid, in addition, can also the screening control be set in client and according to demand screening conditions be set voluntarily by the user.Certainly, for how screening conditions are set, can adopt the method for prior art to realize that the present invention does not need this to be limited.
The preferred embodiment of the present invention selects the reason of entity information to be: at first, by the statistical query to a large amount of searching record of search engine, find wherein to exist a large amount of inquiries all about entity information; Secondly, entity information has stronger determinacy as a result, because entity information is object or notion about being of practical significance in actual life, has more certain corresponding relation, and, the user does not need to open this webpage and further browses, and just can determine the result whether this entity information is inquired about.Therefore, the preferred embodiment of the present invention selects entity information as instant result, both can simplify the step of user search, can guarantee that again instant result's accuracy is higher.
Be that example illustrates instant result of the present invention to return the highest entity information of clicking rate below, so that those skilled in the art understand better.Such as, input " Netease ", search server filters out the highest entity information of clicking rate in instant result database be the homepage of company of Netease, so show " Netease in the prompt column of current page in the prompt column of current page
Www.163.com".Preferably, entity information can also comprise the entity brief introduction, and then when input " Netease ", the instant result who returns as shown in Figure 5.Certainly, described entity brief introduction also can appear at hereinafter in all entity informations.
Under the situation that Search Results is relatively determined, search method of the present invention has been omitted unnecessary search step, thereby has improved user's search efficiency.And, can also make user's operation more directly perceived because the result shows at current page immediately.
Generally comprise Chinese, numeral or alphabetical in user's the input information.When input information was Chinese, if search server matches an entity information in the just in time corresponding instant result database of this Chinese, then returning this entity information was instant result.Possible is, input information is the Chinese abbreviation, and may be a plurality of abbreviations of an entity correspondence, such as input " Beijing University " (abbreviation of Peking University), perhaps " National People's Congress ", " People's University " (abbreviation of the Renmin University of China), in this case, can also dispose entity title abbreviation-entity data bak in the search server, in this database, the abbreviation of entity title forms corresponding relation with entity, search server mates in described entity title abbreviation-entity data bak according to this abbreviation, if can match a corresponding entity information, then returning this entity information is instant result.Such as, the instant result that " Beijing University " returns is " a Peking University
Http:// www.pku.edu.cn"; The instant result that " National People's Congress ", " People's University " return is " the Renmin University of China
Http:// www.ruc.edu.cn".
Preferably, server end can also dispose one by the abridge database of complete entity title of entity title, when the user imports abbreviation, returns the complete name of this abbreviation corresponding entity.For example: when the user is input as " Beijing University ", return complete query word " Peking University ", " Peking University " shown in search column as an everyday words.
When input information is numeral, also dispose numeral-entity data bak in the search server, in this database, digital or specific combination of numbers and entity form man-to-man corresponding relation, search server mates in numeral-entity data bak according to the numeral of input, if can match a corresponding entity information, then returning this entity information is instant result.For example, input " 163 " is returned instant result and is " Netease
Www.163.com".
When input information was letter or monogram, if match a entity information in the just in time corresponding instant result database of this letter or monogram, then returning this entity information was instant result.For example, input " QQ " is returned instant result for " to rise fast net
Www.qq.com".
When input information is phonetic, also dispose phonetic-entity data bak in the search server, in this database, one or a spelling sound and entity form man-to-man corresponding relation, and described phonetic comprises spelling, first letter of pinyin (simplicity) or the combination of spelling simplicity.Search server mates in described phonetic-entity data bak, if can match a corresponding entity information, then returning this entity information is instant result.For example, input " wangyi " or " wy " is returned instant result and is " Netease
Www.163.com".In some cases, if the instant result of phonetic correspondence conflicts mutually with alphabetical corresponding instant result, then preferentially return the corresponding instant result of letter.
The user runs into through regular meeting when input information can not import the situation that input can't be finished in Chinese character etc.; for example; the user wants to visit the homepage of Netease; but can not import " easily " word; so the user is at search column input " net yi "; yet the mode that existing search engine is handled this combination is to be that key word is searched for Chinese " net " and monogram " yi " respectively, all offers the user searching for the result who obtains respectively.This is just far from each other with user's search purpose.And, also be unfavorable for searching and inquiry further of user.When the present invention is the combination of Chinese and letter at this input information of processing, earlier Chinese is converted into phonetic alphabet, with letter composition pinyin string; Wherein, described pinyin string comprises the combination of spelling, the combination of first letter of pinyin (simplicity) or the combination of spelling simplicity.Disposal route when being phonetic according to input information is then mated described pinyin string in the phonetic-entity data bak of search server; If can match a corresponding entity information, then returning this entity information is instant result.For example, input " net yi ", system is translated into " wangyi " earlier, and the disposal route when being phonetic according to input information is then returned instant result and is " Netease
Www.163.com".Therefore, the present invention for input information for the processing of combination of Chinese and letter made things convenient for the user in the time can not importing Chinese character inquiry and saved query steps, under the prerequisite that Search Results is determined, improved the accuracy of Search Results greatly.
When the user imports, might not know also how certain word or word are spelt, do not know in English word which letter this uses, what partial content in the perhaps uncertain input is, in this case, the present invention can make the user that ignorant part is replaced carrying out fuzzy query with asterisk wildcard by introducing Fuzzy Query Technology.The user imports asterisk wildcard in search column, in a single day the shell script of local program or searched page monitors in user's input and contains asterisk wildcard, search server will mate in the everyday words database according to input information, and matching process may further comprise the steps: (1) is that prefix is mated in the everyday words database with the input information before the asterisk wildcard; (2) be that suffix mates in the everyday words database with the input information behind the asterisk wildcard; The everyday words that coupling in (1), (2) is obtained or the instant result of described everyday words correspondence return local program or shell script then.Usually, asterisk wildcard can comprise two kinds: a kind of is to replace zero or a plurality of non-control character with an asterisk wildcard; Another kind is to replace a non-control character with an asterisk wildcard.Asterisk wildcard can be set to various characters as required.
Suppose to replace the asterisk wildcard of zero or a plurality of non-control characters to represent with " * " with an asterisk wildcard.If the user wants to inquire about Pekinese university, can import " Beijing * university " at search column, search server can be that prefix is mated in the everyday words database with " * " preceding " Beijing ", the result that may match is " Peking University ", " tourism of Beijing ", " Tian An-men, Beijing " waits all is the everyday words of prefix with " Beijing ", simultaneously, search server is that suffix mates in the everyday words database with " university " also, the result that may match is " Tsing-Hua University ", " Peking University ", " Nanjing University " waits all is the everyday words of suffix with " university ", then, search server is with the common factor of above-mentioned matching result, the identical everyday words that promptly matches, as " Peking University ", " University of Science ﹠ Technology, Beijing ", " Beijing Institute of Technology " etc. returns the shell script of local program or searched page, and shows this everyday words at the prompt column of the current search page.
The asterisk wildcard of supposing to replace a non-control character with asterisk wildcard with "? " expression.If the user wants to inquire about a name, the name of only knowing this people has three words, first word be " Lee ", the 3rd word is " encouraging ", do not know but what second word be, can import at search column so " Lee? encourage ", search server can be that prefix and suffix mate in the everyday words database with " Lee " and " encouraging " word respectively, obtain the common factor of matching result, the identical everyday words that promptly matches.In identical everyday words, the shell script of the everyday words of 3 characters to local program or searched page only returned in search service, is not the everyday words of 3 characters and do not return other.The everyday words of returning in this example is " Li Dazhao ".
Preferably, the present invention can also be mated in instant result database returning everyday words, an if entity information in the just in time corresponding instant result database of the everyday words of returning, then returning this entity information is instant result, such as, an entity information in the just in time corresponding instant result database of the everyday words of returning " Li Dazhao " then returns instant result for " Lee encourages memorial museum greatly at prompt column
Http:// lidazhao.com/", similarly, the user is as long as determine directly to visit this website by selecting in prompt column.In this case, the present invention can also may further comprise the steps: be called prefix with the physical name among the instant result and mate in the everyday words database of search server, the everyday words that coupling obtains is returned local program or shell script; Show everyday words in the prompt column on current searched page.The everyday words that instant result that this example is returned and coupling obtain as shown in Figure 6.Preferably, instant result has precedence over the everyday words demonstration.Certainly, obtain in aforementioned arbitrary embodiment all to make the everyday words that further obtains coupling in this way on instant result's the basis, be not described in detail in this.
The present invention can help the user still can obtain the information of oneself wanting directly, exactly in the time can't finishing input by introducing fuzzy query.And this method not occupying system resources, realize simple, do not have special secret algorithm, cost is lower.
If do not obtain the instant result and the everyday words of any coupling by search method of the present invention, then will from the everyday words database of search server, mate the everyday words the most close that obtains and return local program or shell script as error correction term with input information; Show error correction term in the prompt column on current searched page then.When the user can't describe the inquiry of oneself exactly,, can help the user directly to obtain input information and Search Results accurately by the information of error correction term.
In practice, the user often can repeat inquiry to some search words, and therefore wishing in input process can be with reference to the historical search record.In order to address this problem, the present invention can also may further comprise the steps: be that prefix is mated in the historical search speech database of search server with the input information, the historical search speech that coupling is obtained returns local program or shell script; Show the historical search speech in the prompt column on current searched page.Wherein, historical search speech database can exist local side also can have server end.When the user triggers local program or shell script and begins to import, just can obtain the information of historical search speech, in case definite historical search speech is arranged, the user can select to determine to return the instant result and the everyday words of this historical search speech correspondence in prompt column.Preferably, instant result has precedence over the historical search speech and shows, the historical search speech has precedence over everyday words and shows.
If the user is accustomed to using local collection or network bookmark, the present invention can also be mated input information in local collection, and user's bookmark and classified information thereof that coupling obtains are returned local program; Perhaps, input information is mated in user's bookmark database of search server, user's bookmark and classified information thereof that coupling obtains are returned shell script; Explicit user bookmark and classified information thereof in the prompt column on current searched page then.Similarly, the user can select to determine to return the instant result and the everyday words of this user's bookmark correspondence in prompt column.In this case, same input information may corresponding a plurality of user's bookmarks, and a plurality of bookmarks can be shown to the user simultaneously, but each fixed number (such as 8 or 10) that shows, show that number can select as required.In addition, if the user does not classify to bookmark, displaying contents does not then comprise the classified information of bookmark so.
The user often wants to understand the popular information of each side such as nearest current events are dynamic, news when searching for, in order to meet consumers' demand more fully, to make and search for hommization more, and the present invention can also may further comprise the steps:
Preset the popular search key, such as, presetting space bar is the popular search key;
When input information was described popular search key, the top search term database of match search server returned the top search term in the database to local program or shell script;
Show top search term in the prompt column on current searched page.For example " Paralympic Games ", " Liu Xiang ", " NBA " or the like.
By above-mentioned everyday words, error correction term, historical search speech, top search term and user's bookmark are set, the user can carry out the input of " fool " formula fully, just can not carry out the user of any input operation at last, all can realize its search purpose.Certainly, the service supplier can also be provided with more information as required voluntarily with user-friendly, and the present invention does not need this to limit.
At any time nowadays surfing Internet with cell phone is more and more universal, and more user uses search engine by mobile phone.The present invention is applied to the surfing Internet with cell phone field with its core idea, the search operation when also having further facilitated surfing Internet with cell phone.Because cell phone keyboard is generally less, the corresponding button of a plurality of English alphabets meetings, and a button also is a numerical key usually.So, when the user during input information, can also may further comprise the steps in search column by cell phone keyboard:
The combination of numbers of cell phone keyboard input is converted into monogram;
Described monogram is mated in the english database of search server, and the english that coupling is obtained is returned the shell script of the local program or the mobile phone searching page, shows english in the prompt column on the current search page; Described english comprises English word, english abbreviation or the english of certain sense is arranged, such as " QQ ";
Perhaps, described monogram is mated in the everyday words database of search server, the monogram commonly used that coupling is obtained returns the shell script of the local program or the mobile phone searching page, shows monogram commonly used in the prompt column on the current search page; Such as, input digit " 426 " shows that letter commonly used is combined as " IBM ", " HBO " etc.;
Perhaps, described monogram is mated in the phonetic-everyday words database of search server, the Chinese everyday words that coupling is obtained is returned the shell script of the local program or the mobile phone searching page; Chinese display everyday words in the prompt column on the current search page.Described phonetic comprises the combination of spelling, initial phonetic (simplicity) and spelling simplicity.Such as, input digit " 99 " can be converted into monogram " WY ", " XW " etc., and the Chinese display everyday words is " Netease ", " news " etc.Certainly, as another embodiment, if an entity information in the corresponding instant result database of described english or monogram,
Then also returning this entity information is instant result, is not described in detail in this.
With reference to Fig. 2, be the structured flowchart of a kind of information retrieval system based on search engine of the present invention, comprise with lower member:
Wherein, described instant result database is entity information database, phonetic-entity data bak or numeral-entity data bak; Described entity information comprises entity title and entity network address, object or the notion of described entity for being of practical significance in actual life.
With reference to Fig. 3, be based on the flow chart of steps that system shown in Figure 2 realizes information retrieval, may further comprise the steps:
The instant result of step 303, search server 203 is mated subelement 2032 described input information is being mated in instant result database, if corresponding instant result is arranged then should instant result return to local program or shell script;
