TECHNICAL FIELD
The present invention relates to a method and system for autocompleting a general recommended word and an advertising recommended word, which can store an autocomplete general recommended word and an autocomplete advertising recommended word, extract the autocomplete general recommended word and the autocomplete advertising recommended word according to a user input query received from a user, and provide the user with the extracted autocomplete general recommended word and the autocomplete advertising recommended word and thereby can improve advertising effects.
BACKGROUND ART
When a query is entered from a user, a search website, which provides a search service, generally provides search results corresponding to the query, for example, web sites including the query, articles including the query, and images including the query as a file name.
Search services are currently being improved to increase users' convenience. Accordingly, when a user enters an appropriate query, the search service must provide satisfactory search results. Also, even when the user enters an inappropriate query, the search service must provide appropriate search results which can satisfy the user. Specifically, as users of search services are being expanded and also users who do not have enough background knowledge about appropriate queries increase, it is required to guide the users to make an appropriate query.
Also, when a user enters a mistyped character into a search window, how to handle the mistyped character and provide the user with satisfactory search results becomes an issue. The mistyped character may be generated, for example, 1) when a pronunciation is similar such as “Emma Wattson” and “Emma Watson”, orthographies of borrowed words are confused, 2) when visually similar characters are confused, such as “the Uruguay Round” and “Anna's Diary”, 3) when a user enters a special character via a keyboard, such as “]”, and “!”, and 4) when using alphabetical characters for Hangul. Accordingly, a proper solution for the entered mistyped character is required.
However, in the conventional search service, only passive solutions are utilized, such as 1) a method of converting a query into another query and providing search results using a predetermined converting list, when a user enters the query into a search window for a search request and the query is included in the converting list, and 2) a method of outputting search results even when the user enters a wrong query, and recommending at least one other query to the user.
Specifically, the method 1) may output search results with respect to a query that the user does not substantially desire. Also, the method 2) initially outputs search results with respect to the wrongfully entered query and subsequently recommends another query to the user. Accordingly, the user is required to select the other query and request the search again.
Also, according to the methods 1) and 2), search service providers must repeatedly perform predetermined operations, such as preparing any possible mistyped characters, and adding the same to a converting list or a recommendation list with a large number of human resources. Accordingly, some delays may occur in other important fields such as site registration or creating and searching of contents, which may also deteriorate productivity.
Accordingly, a new type of technology which can prevent a mistyped character before a user enters a query, and also can classify a query log for each index based on various standards, and automatically complete the query the user is currently entering, according to a user input query and a setting mode which are received from the user's web browser, so as to significantly improve a mistyped character correction function of a search service is required.

BEST MODE FOR CARRYING OUT THE INVENTION
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 1 illustrates a network connection of a system for autocompleting a general recommended word and an advertising recommended word according to an exemplary embodiment of the present invention.
A system for autocompleting a general recommended word and an advertising recommended word (hereinafter, referred to as “recommended word autocompletion system”) 100 maintains an autocomplete general recommended word in a first database, and maintains an autocomplete advertising recommended word in a second database. According to the present exemplary embodiment, the recommended word autocompletion system 100 indexes the autocomplete general recommended word and the autocomplete advertising recommended word according to any one of a consonant/vowel unit, a syllable unit, and a suffix using an autocomplete indexer component, and classifies and stores the indexed autocomplete general recommended word and the autocomplete advertising recommended word into any one of a consonant/vowel unit index, a syllable unit index, and a suffix index in an autocomplete index database.
A user accesses a web server of the recommended word autocompletion system 100 via a wired/wireless network using a user terminal 101 and enters a query.
In this instance, the web server receives a user input query from the user, and transfers the received user input query to a query autocompletion server of the recommended word autocompletion system 100. Also, the query autocompletion server receives the user input query from the web server, extracts an autocomplete general recommended word and an autocomplete advertising recommended word associated with the user input query from an autocomplete index server, and transmits the extracted autocomplete general recommended word and the autocomplete advertising recommended word to the web server. Accordingly, the web server receives the autocomplete general recommended word and the autocomplete advertising recommended word from the query autocompletion server, and displays the same on a webpage.
FIG. 2 is a block diagram illustrating a configuration of a system for autocompleting a general recommended word and an advertising recommended word according to an exemplary embodiment of the present invention.
A recommended word autocompletion system 200 according to the present exemplary embodiment may include a first database 201 configured to maintain an autocomplete general recommend word, a second database 202 configured to maintain an autocomplete advertising recommended word, an autocomplete indexer component 203 configured to index the autocomplete general recommended word and the autocomplete advertising recommended word according to any one of a consonant/vowel unit, a syllable unit, and a suffix, an autocomplete index database 204 configured to classify and store the indexed autocomplete general recommended word and the autocomplete advertising recommended word into any one of a consonant/vowel unit index, a syllable unit index, and a suffix index, a web server 206 configured to receive a user input query from a user, and transmit the user input query to a predetermined query autocompletion server 205, and receive the autocomplete general recommended word and the autocomplete advertising recommended word from the query autocompletion server 205 and display the autocomplete general recommended word and the autocomplete advertising recommended word on a predetermined webpage, and the query autocompletion server 205 configured to receive the user input query from the web server 206, extract the autocomplete general recommended word and the autocomplete advertising recommended word from the autocomplete index database 204, and transmit the extracted autocomplete general recommended word and the autocomplete advertising recommended word to the web server 205.
Also, according to another exemplary embodiment of the present invention, the web server 206 may display the autocomplete general recommended word in a predetermined display area. Also, the web server 206 may utilize a predetermined portion of the display area into an advertising area, and display the autocomplete advertising recommended word in the advertising area. In this instance, the web server 206 may display the autocomplete advertising recommended word to be distinguished from the autocomplete general recommended word.
Also, according to still another exemplary embodiment of the present invention, the recommended word autocompletion system 200 further includes an account server 207 configured to charge an account of an advertiser with an advertising cost which is based on displaying the autocomplete advertising recommended word, sold to the advertiser, on the webpage. For example, the account server 207 may count a number of clicks that the user clicks the autocomplete advertising recommended word, and calculate the advertising cost based on the number of clicks. Also, the account server 207 may display the autocomplete advertising recommended word on the webpage during a predetermined period of time, and calculate the advertising cost based on the display period of time. Also, the account server 207 may sell the autocomplete advertising recommended word using a predetermined auction rule.
FIG. 3 is a flowchart illustrating a method of autocompleting a general recommended word and an advertising recommended word according to an exemplary embodiment of the present invention. The method of autocompleting the general recommended word and the advertising recommended word according to the present exemplary embodiment may be performed by the recommended word autocompletion system 200.
In operation S301, the query autocompletion server 205 of the recommended word autocompletion system 200 maintains an autocomplete general recommended word in the first database 201.
The autocomplete general recommended word may be a set of total queries that users enter in a predetermined search web site of the web server 206 of the recommended word autocompletion system 200. Also, the autocomplete general recommended word may include search frequency for each query. In this instance, the search frequency may be, for example, a type of statistical information which is generated by analyzing how many times a particular query has been inputted during a predetermined period.
In operation S302, the query autocompletion server 205 maintains an autocomplete advertising recommended word in the second database 202.
FIG. 4 illustrates an example of the second database 202 storing autocomplete advertising recommended words classified for each index.
As shown in FIG. 4, the second database 202 may include autocomplete advertising recommended words for each index. In this instance, the autocomplete advertising recommended word indicates a recommended query for advertising and thus includes information about a Universal Resource Locator (URL) which directly connects with a corresponding homepage or enables corresponding advertising to be displayed as search results. For example, in the case of a consonant/vowel unit, ‘[GameNara]’, ‘[GoGoGame]’, and the like may be stored as autocomplete advertising recommended words for a consonant/vowel unit ‘[g]’. Also, ‘[NetMarble]’, ‘[Norajo]’, and the like may be stored as autocomplete advertising recommended words for a consonant/vowel unit ‘[n]’. Also, ‘[DehanHangong] (Korean Air in English), ‘[DCinside]’, and the like may be stored as autocomplete advertising recommended words for a consonant/vowel unit ‘[d]’.
Also, in the case of a syllable unit, ‘[GanjiNara]’, ‘[GandaTour]’, and the like may be stored as autocomplete advertising recommended words for a syllable unit ‘[gan]’. Also, ‘[Naruto]’, ‘[Naiki]’, and the like may be stored as autocomplete advertising recommended words for a syllable unit ‘[na]’. Also, ‘[DangNaGui]’(donkey in English), ‘[Dang119Dotkom]’, and the like may be stored as autocomplete advertising recommended words for a syllable unit ‘[dang]’.
Also, in the case of a suffix, ‘[SamsungDika] (Samsung digital camera in English)’, ‘[SoniDika] (Sony digital camera in English)’, and the like may be stored as autocomplete advertising recommended words for a suffix ‘[dika]’(digital camera in English). Also, ‘[MisoSunghyung]’, ‘[ChamjinSunghyung]’, and the like may be stored as autocomplete advertising recommended words for a suffix ‘[sunghyung]’ (plastic surgery in English). Also, ‘[Hanuri]’, ‘[Yauri]’, and the like may be stored as autocomplete advertising recommended words for the suffix ‘[uri]’.
In operation S303, the web server 206 receives a user input query from a user and transmits the user input query to the query autocompletion server 205. In the present exemplary embodiment, the web server 206 may receive the user input query and a setting mode from the user. In this instance, the setting mode may include selection information about at least one of the consonant/vowel unit index, the syllable unit index, and the suffix index.
In operation S304, the query autocompletion server 205 receives the user input query from the web server 206, and extracts the autocomplete general recommended word and the autocomplete advertising recommended word from the autocomplete index database 204 in association with the user input query.
The autocomplete indexer component 203 indexes the autocomplete general recommended word, stored in the first database 201, and the autocomplete advertising recommended word, stored in the second database 202, according to any one of a consonant/vowel unit, a syllable unit, and a suffix. For the above operation, the autocomplete indexer component 203 may include a consonant/vowel unit indexer component, a syllable unit indexer component, and a suffix indexer component.
Accordingly, a single query may be classified using only one method, and also classified as all of the consonant/vowel unit, the syllable unit, and the suffix according to a method where the query is indexed. As an example, a query “[DangNaGui]” may be indexed into “[d]”, “[da]”, “[dang]”, “[dangn]”, “[dangna]”, “[dangnag]”, “[dangnagu]”, and “[dangnagui]” according to the consonant/vowel unit. Also, the query may be indexed into “[Dang]”, “[DangNa]”, and “[DangNaGui]” according to the syllable unit, and may also be indexed into “[Gui]”, “[NaGui]”, and “[DangNaGui]” according to the suffix.
The greatest distinguishing characteristic of Hangul (Korean), which is different from other foreign characters such as Chinese characters, is that Hangul consists of consonant units and vowel units. Specifically, Hangul includes basic consonants and vowels which include 19 initial sounds, 21 intermediate sounds, and 28 final sounds, and regularly combine the basic consonants and vowels to generate a word. Depending upon the character of Hangul, the consonant/vowel indexer component of the autocomplete indexer component 203 functions to classify queries maintained in the first database 201 according to the consonant/vowel unit.
The term “consonant/vowel unit” used throughout the present specification includes a general meaning of consonants and vowels, such as the initial sounds, the intermediate sounds, and the final sounds, and also includes all the characters and words which are generated by combining the initial sound and the final sound. As an example, “[da]” may be divided into two consonant/vowel units, such as “[d]” and “[a]”. Also, “[da]” itself may correspond to a single consonant/vowel unit.
Also, in the present invention, the term “consonant/vowel unit” includes a concept of a “minimal input unit of an input terminal”. As an example, “[o]” and “[a]” must be entered to generate the single vowel “[wa]” in a Hangul dual mode keyboard. In the case of a simple consonant/vowel unit, a word “[wawo]” may be indexed into “[w]”, “[wa]”, “[waw]”, and “[wawo]”. However, in the present invention, as described above, the “consonant/vowel unit” includes the concept of the “minimal input unit of the input terminal”. Accordingly, in the case of a Hangul dual mode keyboard, the word “[wawo]” may be indexed into “[w]”, “[wo]”, “[wa]”, “[waw]”, and “[wawo]”. Also, when the input terminal is changed into another terminal following a different input method, indexes of the minimal input unit may be changed.
Also, the syllable unit indexer component of the autocomplete indexer component 203 functions to classify autocomplete general recommended words maintained in the first database 201 according to the syllable unit. Also, the suffix indexer component of the autocomplete indexer component 203 functions to classify autocomplete advertising recommended words maintained in the second database 202 according to the suffix.
The suffix is a kind of affix, and is added to the end of a word to add a meaning, and thereby generally generates another word. Also, the suffix may not be used alone, and is combined to the root of a word to add various meanings. As an example, suffixes, which are added to substantives, may include ‘[nim]’ which designates a honorific title, ‘[su]’, ‘-[ja]’, etc. which designates an operating subject, ‘[dul]’ which designates pluralality, and ‘-[hwa]’, ‘-[sik]’, ‘[guk]’, and the like.
However, in the present invention, the term “suffix” includes the same usage as in the English language, and also designates all the words and characters which can be added to a tail of a word.
As an example, ‘[gukga]’ (nation in English) does not correspond to a general meaning of a suffix, but can be added to the tail of another world, such as ‘[Minju Gukga]’, ‘[Bupchi Gukga]’, ‘[E Gukga]’, and the like. Accordingly, in the present invention, “[Gukga]” falls within the scope of the suffix. As described above, in the present invention, the “suffix” corresponds to “a syllable unit index from a tail of a word”. As an example, a term “[HyungWeGa]” itself may not be a complete noun, such as “[gukga]”, but completes a query such as “[Miso SungHyungWeGa]” and “[HongGilDong JungHyungWeGa]”. Accordingly, “[HyungWeGa]” also falls within the scope of the suffix.
In the present exemplary embodiment, a single query may be divided using only a single index, and also may be divided using all of the consonant/vowel unit, the syllable unit, and the suffix according to a method where the query is indexed. As an example, an autocomplete general recommended word “[DangNaGui]” may be recorded in the consonant/vowel unit index, such as “[d]”, and also recorded in the syllable unit index, such as “[dang]”. Also, the autocomplete general recommended word “[DangNaGui]” may be recorded in the suffix index, such as “[gui]”.
According to another exemplary embodiment of the present invention, the query autocompletion server 205 extracts at least one autocomplete advertising recommended word for advertising, and extracts at least one autocomplete general recommended word for the user convenience. Accordingly, a comparatively smaller number of autocomplete advertising recommended words than autocomplete general recommended words may be extracted. Specifically, the query autocompletion server 205 may extract, for example, only one or two autocomplete advertising recommended words less than the extracted autocomplete general recommended words.
According to still another exemplary embodiment of the present invention, the query autocompletion server 205 may extract a predetermined number of autocomplete general recommended words in an order of search frequency in association with the user input query when extracting autocomplete general recommended words.
As an example, when a user enters “[d]” into a search window, the query autocompletion server 205 may extract, for example, only eight autocomplete general recommended words, without extracting all autocomplete general recommended words starting with “[d]”. In this instance, the query autocompletion server 205 may determine eight autocomplete general recommended words in an order of search frequency. Accordingly, only most probable queries may be provided for the user.
In operation S305, the query autocompletion server 205 transmits the extracted autocomplete general recommended word and the autocomplete advertising recommended word to the web server 206.
In operation S306, the web server 206 receives the autocomplete general recommended word and the autocomplete advertising recommended word, and displays the autocomplete general recommended word and the autocomplete advertising recommended word on a predetermined webpage. In this instance, the web server 206 may utilize a predetermined portion of a display area into an advertising area, display the autocomplete general recommended word in the display area, and display the autocomplete advertising recommended word in the advertising area. As an example, the web server 206 may display the autocomplete advertising recommended word in a larger font than the autocomplete general recommended word. Also, the web server 206 may display the autocomplete advertising recommended word using a different color from the autocomplete general recommended word or may underline the autocomplete advertising recommended word.
FIG. 5 illustrates an example of an autocomplete query list provided for a user when the user enters a query based on a consonant/vowel unit according to an exemplary embodiment of the present invention.
As shown in FIG. 5, when the user enters “[d]” in a search window, a setting mode is automatically selected as selection information about the consonant/vowel unit. The recommended word autocompletion system 200 may perform operations S303 through 306 and thereby display the autocomplete query list below the search window. In this instance, the autocomplete query list may include autocomplete general recommended words, such as ‘[daum]’, ‘[dokdo]’ (Korean island), and the like, and autocomplete advertising recommended words, such as ‘[dehanhangong]’ (Korean Air in English), ‘[dcinside]’, and the like, which are classified as the consonant unit index “[d]”.
In this instance, the web server 206 may utilize a predetermined portion of a display area 501 into an advertising area 502, and display the autocomplete advertising recommended word in the advertising area 502 which is an eye-catching place for the user. Also, as shown in FIG. 5, the advertising area 502 may be set to a center portion of the display area 501. In this instance, the web server 206 may display the autocomplete advertising recommended words to be distinguished from the autocomplete general recommended words. Also, the web server 206 may display an advertising icon 503 with the autocomplete advertising recommended word so that the user may readily recognize the autocomplete advertising recommended word.
FIG. 6 illustrates an example of an autocomplete query list provided for a user when a consonant/vowel unit is selected as a setting mode according to an exemplary embodiment of the present invention.
As shown in FIG. 6, when the user enters “[da]” into a search window, a setting mode may correspond to selection information about any one of a consonant/vowel unit index, a syllable unit index, and a suffix index. In FIG. 6, the autocomplete query list may be displayed for the user when the consonant/vowel unit index is selected as the setting mode.
As described above, except when a last syllable of a user input query is terminated with an initial sound, the setting mode for any user input query may include selection information about any one of the consonant/vowel unit index, the syllable unit index, and the suffix index. In this instance, different query search results may be displayed depending upon which one is selected as the setting mode.
In this instance, the setting mode may be selected by the user or may be randomly selected by the recommended word autocompletion system 200.
As described above, the recommended word autocompletion system 200 may receive “[da]” as the user input query and “consonant/vowel unit index” as the setting mode, and then performs operations S303 through S306, and thereby display the autocomplete query list below the search window. In this instance, the autocomplete query list may include autocomplete general recommended words, such as ‘[danawa]’, ‘[dajaba]’, ‘[dangnagui]’, and the like, and autocomplete advertising recommended words, such as ‘[daum]’, ‘[damoim]’, and the like, which are classified as the consonant unit index “”.
In this instance, the web server 206 may utilize an upper portion of a display area as an advertising area 601, and display the autocomplete advertising recommended words in an upper portion of the autocomplete query list to be distinguished from autocomplete general recommended words. Also, as show in FIG. 6, the web server 206 may display an advertising icon 602 with the autocomplete advertising recommended word.
According to the present exemplary embodiment, since autocomplete advertising recommended words may be stored for each index of queries, different autocomplete advertising recommended words may be displayed for each of a consonant, a syllable unit index, and a suffix index. As an example, ‘[daum]’ may be set to be displayed as an autocomplete advertising recommended word for only the syllable unit index. Accordingly, in the case of the consonant/vowel unit index as shown in FIG. 6, ‘[daum]’ may be displayed as the autocomplete general recommended word, not the autocomplete advertising recommended word. In the case of the syllable unit index, ‘[daum]’ may be displayed as the autocomplete advertising recommended word.
FIG. 7 illustrates an example of an autocomplete query list provided for a user when a syllable unit index is selected as a setting mode according to an exemplary embodiment of the present invention.
When the user enters “[uri]” into a search window, and the syllable unit index is selected as a setting mode, the autocomplete query list as shown in FIG. 7 may be displayed for the user. As described above, the setting mode may be selected by the user or may be randomly selected by the recommended word autocompletion system 200.
As described above, the recommended word autocompletion system 200 may receive ‘[uri]’ as the user input query and “syllable unit index” as the setting mode and then perform operations S303 through S306, and thereby display the autocomplete query list below the search window. In this instance, the autocomplete query list may include autocomplete general recommended words, such as ‘[uribank check]’, ‘[uri]’, and the like, and autocomplete advertising recommended words, such as ‘[uri bank]’, ‘[uri homeshopping]’, and the like, which are classified as the syllable unit index “[uri]”.
In this instance, the web server 206 may display the autocomplete advertising recommended words in an advertising area 701 to be distinguished from autocomplete general recommended words. Specifically, the web server 206 may utilize an upper portion of the autocomplete query list as the advertising area 701 and display the autocomplete advertising recommended words in the upper portion of the autocomplete query list. Also, the web server 206 may display an advertising icon 702 with the autocomplete advertising recommended word.
FIG. 8 illustrates an example of an autocomplete query list provided for a user when a suffix index is selected as a setting mode according to an exemplary embodiment of the present invention.
When the user enters “[dika]” into a search window, and the suffix index is selected as a setting mode, the autocomplete query list as shown in FIG. 8 may be displayed for the user. As described above, the setting mode may be selected by the user or may be randomly selected by the recommended word autocompletion system 200.
As described above, the recommend word autocompletion system 200 receives “[dika]” as the user input query, and “suffix index” as the setting mode and then performs operations S303 through S306 and thereby displays the autocomplete query list below the search window. In this instance, the autocomplete query list may include autocomplete general recommended words, such as ‘[dika]’, ‘[jungo dika]’, and the like, and autocomplete advertising recommended words, such as ‘[samsung dika]’, ‘[soni dika]’, and the like, which are classified as the suffix index “[dika]”.
In this instance, the web server 206 may utilize an intermediate portion of a display area as an advertising area 801, and display the autocomplete advertising recommended words in the advertising area 801 to be distinguished from the autocomplete general recommended words. Also, the web server 206 may display an advertising icon 802 with the autocomplete advertising recommended word.
According to an exemplary embodiment of the present invention, the account server 207 calculates an advertising cost based on a number of clicks or a display period of time. Specifically, the account server 207 may count a number of clicks that the user clicks the autocomplete advertising recommended word, and calculate the advertising cost based on the number of clicks. As an example, the account server 207 may calculate the advertising cost based on the number of clicks, such as 100 won per click, 7000 won per 100 clicks, and the like, or based on the display period of time, such as 10,000 won for ten days, 100,000 won for thirty days, and the like. The account server 207 may create benefits by charging an account of an advertiser, and registering the autocomplete advertising recommended word. Also, the account server 207 may sell the autocomplete advertising recommended word using an auction rule.
