Description

TECHNICAL FIELD [0001] The present invention relates to a search system and a method for providing an extended information function,

The present invention relates to a search system and method for providing an extended information function, and more particularly, to a search system and method for providing an extended information function, To a search system and method for providing results.

With the development of the network environment, the information that exists on the online is increasing exponentially. A search service is a service for finding and providing information desired by a user from a vast amount of information on-line, and when a user inputs a search word, a method of providing a link of a web page matching the search word is widely used. In recent years, search algorithms have been developed to search for web pages that match the search terms, and to provide the user with the information desired by the upper rank.

However, in spite of the development of search algorithms, it is difficult to grasp the user's intention by simply listing the simple search terms, and thus it is difficult to establish a criterion on which search results should be provided as the upper rank. Also, the surge in online information has caused the user to spend more time searching for desired information than before.

Thus, the user can input the search word more specifically to obtain the result of the search result. For example, if a user inputs a category name to be searched together with a word to be searched with the searched keyword, the search result belonging to the category can be displayed first. However, in most cases, the user performs a search using only the original keyword, and in many cases, he / she categorizes the desired category among the search results. Therefore, it may take a long time to obtain the search result or the search result matching the user's intention may be displayed in the lower rank order.

Meanwhile, recent search service providers are using the auto complete query function. An autocomplete search term refers to a search term in which, when a user enters text in a search window, a keyword that has been frequently input by other users based on input text is provided in advance. For example, if a user enters 'auto' into the search box, 'auto,' 'auto insurance,' etc. can be provided as an autocomplete query.

The present invention provides a function of selecting extended information corresponding to the user's intention, thereby providing a search result matching the search intention when the user selects the extended information.

Another object of the present invention is to enable a user to perform a search using detailed information of a desired search word as a search word without inputting additional keywords.

In order to accomplish the above object, a representative structure of the present invention is as follows.

According to an embodiment of the present invention, there is provided an information processing apparatus including a search word completion unit for receiving a search word from a user terminal and determining an autocomplete list corresponding to a search word inputted so far; A search word matching unit for determining whether one or more extension information matched to each of the autocomplete search terms included in the autocomplete list exists in the database; An extension information display unit for displaying the at least one extension information; A search word determining unit that receives a selection signal for selecting any one of the one or more extension information, and determines an extended search term based on the automatic completion word and the selected extension information; And a search result adjustment unit for sorting and displaying the integrated search results corresponding to the extended search word determined by the search word determination unit for each vertical service to which each of the integrated search results belongs, And determining the order of each of the vertical services in a descending order of association with the search word, and displaying each of the integrated search results.

According to another embodiment of the present invention, there is provided a search method comprising: a search term completion step of receiving a search term from a user terminal and determining an autocomplete list corresponding to a search term entered so far; A search word matching step of determining whether one or more extension information matched to each of the autocomplete search terms included in the autocomplete list exists in the database; An extension information display step of displaying the at least one extension information; A search word determining step of receiving a selection signal for selecting any one of the one or more extension information and determining an extended search term based on the autocomplete search word and the selected extension information; And arranging and displaying the integrated search results corresponding to the determined extended search word for each vertical service to which each integrated search result belongs and displaying the aligned search result, And determining the order of each of the vertical services in order of relevance to the search word and displaying each of the integrated search results.

1 is a diagram illustrating a configuration of a search system according to an embodiment of the present invention.

Referring to FIG. 1, the search system of the present invention is a service providing server 100. An administrator terminal 200 and a user terminal 300.

The service providing server 100 according to an embodiment of the present invention is a server that receives a search word from a user and provides search results. The service providing server 100 of the present invention is a server providing a portal service have. Although one service providing server is shown in the embodiment of FIG. 1, it is needless to say that a plurality of servers may exist depending on the amount of connection or the amount of data.

The service providing server 100 may provide various services for enhancing the convenience of the user in addition to the general search service. That is, the service providing server 100 of the present invention can provide various services such as e-mail, news, and shopping information in addition to the search service.

The service providing server 100 according to an embodiment of the present invention may be a server that provides a search service. The search service is a service for providing information on the Internet conforming to a user's search condition, and can provide additional services that facilitate search.

In particular, the service providing server 100 according to an exemplary embodiment of the present invention provides extension information for a search term so that the user can intentionally search for the search term. Thus, if the user selects the extension information, It is possible to provide a matching search result. The configuration in which the service providing server 100 provides extended information will be described in detail below.

In addition, the service providing server 100 according to an embodiment of the present invention can sort and display search results according to a vertical service. For example, if a user enters 'Moulin Rouge' as a search keyword, searching for 'Moulin Rouge' in the category of a movie results in a search for 'Moulin Rouge' in a blog category, resulting in 'Moulin Rouge' in the Shopping category. As a result of the selection, the result of searching for 'Moulin Rouge' in the news category can be divided and provided on the screen. At this time, the service providing server can adjust the exposure order of each of the vertical services according to the characteristic of the search term. The search term 'Moulin Rouge' is most relevant to the movie category, so you can expose the result of searching for 'Moulin Rouge' at the top of the movie category.

The administrator terminal 200 refers to a terminal that can input control commands and various contents of the service providing server 100 in a wired / wireless communication environment. According to an embodiment of the present invention, the administrator terminal 200 can directly input the extension information managed by the service providing server 100 into the database. For example, you can enter movies Moulin Rouge, Ji-ming Moulin Rouge, etc. as extension information for Moulin Rouge.

The user terminal 300 may be a personal computer equipped with a web browser capable of using a search service provided by the service providing server 100. The user can use the search service according to an embodiment of the present invention through the user terminal 300. [ Although the user terminal 300 is illustrated as a personal computer in FIG. 1, the concept of the present invention is not limited thereto, and the electronic terminal capable of web browsing as described above can be borrowed without limitation. For example, the user terminal 300 may be a mobile terminal, a telematics telematics terminal, a smart phone, a portable terminal, a personal digital assistant (PDA), a PMP Portable multimedia player) terminal, a computer, a WiBro terminal, an IPTV (Internet Protocol Television) terminal, a navigation terminal, an AVN (Audio Video Navigation) terminal, an A / V And a terminal.

2 is a block diagram illustrating an internal configuration of a service providing server 100 according to an embodiment of the present invention.

Referring to FIG. 2, the service providing server 100 of the present invention includes a search word completion unit 110, an extension information management unit 120, a search word matching unit 130, an extension information display unit 140, a search word determination unit 150, And a search result adjustment unit 160.

First, the search word completion unit 110 receives a search word from a user terminal according to an embodiment of the present invention, and determines an autocomplete list including autocomplete search terms corresponding to the search term input so far.

The autocomplete search term is a search term that has been automatically completed based on the search term entered by the user so far. For example, if the user only scrambles up to 'Moulin', the search term completion unit 110 may determine the Moulin Rouge, Moulin Rouge way, Moulin Rouge down, Paris Moulin Rouge, . The search term completion unit 110 may determine one or more autocomplete search terms for the search term entered by the user.

Since there is a limitation on the display screen size of the user terminal 300, the search term completion unit 110 may generate a limited number of the autocomplete search terms as an autocomplete list to provide to the user terminal 300. At this time, the auto-complete query list can be determined based on the popularity of the autocomplete search terms with reference to the inputted search term. For example, a certain number of autocomplete search terms may be included in the autocomplete list in order of the search terms that the user has input most of the search terms including 'Mantle'.

In addition, the search term completion unit 110 can sort the autocomplete search terms in the order of the user's search frequency in the autocomplete search term list. In one embodiment of the present invention, for example, if 'Moulin Rouge, Moulin Rouge lady mamalade, Moulin Rouge ost, Moulin Rouge your song, Moulin Rouge underwear' is an autocomplete list, 'Moulin Rouge' , And 'Moulin Rouge underwear' may have the lowest frequency of search among the auto-complete search terms in the list. This is to place the autocomplete search word that is most likely to be selected by the user at the top of the list.

The extended information management unit 120 manages extension information of the autocomplete search words according to an embodiment of the present invention. In one embodiment of the present invention, the extended information is information including additional information that allows a user to perform one of multiple semantics or detailed lists when the automatic completion keyword has multiple semantics or detailed lists. Extension information may include additional information such as categories, keywords, and a detailed list in an autocomplete query to clearly understand the user's search intention.

In the past, there was no way to grasp the user's intention of retrieving by performing an integrated retrieval based on only the retrieval term itself, even when the retrieval word has multiple meanings, has a plurality of categories, or has a detailed item or list. The search results were provided at once. For example, the search term 'Moulin Rouge' could mean Moulin Rouge, a local name in Paris, the movie Moulin Rouge, or Moulin Rouge, the name of a shopping mall. If the user inputs only 'Moulin Rouge', he can not know which Moulin Rouge he wants information, so the search result includes all the search results for the above multiple meanings. In this case, the user takes additional time to extract the desired information.

According to an embodiment of the present invention, extended information for more accurately grasping the intention of the user can be provided for each autocomplete query. For this, the extended information management unit 120 may manage the extended information and the automatic completion query by matching. Of course, there are some autocomplete search terms that have a clear meaning and can be output as a unified result.

FIG. 3 is a table that classifies extension information that can be generated according to an embodiment of the present invention according to type.

Referring to FIG. 3, the type of extended information according to an exemplary embodiment of the present invention includes an homonym, an identical name, a list type, and an information type. According to an embodiment of the present invention, the information may be extended information regardless of the type and the category, as long as it relates to information that can clearly grasp the user's search intention in addition to information belonging to the category illustrated in Fig.

First, a homonym-type autocomplete search term refers to a search term in which one word includes a plurality of meanings. For example, if the autocomplete query is 'spy', the user's search intent may be to search for the opening movie Spy, or search for the spy, which is the cartoon title. In this case, the contents are reproduced from a plurality of works under the same title. According to an embodiment of the present invention, the type of work is included in the extension information, thereby allowing the user to select the work information to clarify the search intention.

In the embodiment of FIG. 3, the extension information for 'spy' includes 'movie spy' and 'cartoon spy', which include additional keywords 'movie' and 'cartoon', respectively. In addition, if the name of the same title is used as an example of an autocomplete search term for homonyms, the extended information may be 'drama king Sejong' or 'book king Sejong'.

In addition, there may be proper nouns related to the place name by the homonym type autocomplete search term. For example, the search term 'Veracruz' is a Mexican name, but it is also used as a car model name. In this case, if you enter only "Veracruz", you will not know what your intent is. Accordingly, the extension information management unit 120 can generate the extension information 'car vera cruise' and 'Mexico vera cruise' by combining the additional keywords 'car and Mexico' with 'vera cruise'. Also, as illustrated in FIG. 3, it is possible to generate 'football barcelona' and 'travel barcelona' as extended information for the homonym-type autocomplete search term 'Barcelona'.

Next, an autocomplete search term of the same name is a case where an autocomplete search term is a person's name, and a plurality of persons having the corresponding name exist. For example, if the search term is 'Yoo Seung-woo', it is unclear whether the user's search intention is to search for Yoo Seung-woo or to find Yoo Seung-woo, a member of parliament. The extended information management unit 120 may generate additional information such as 'National Assembly member Yoo Seung-woo' and 'Singer Yoo Seung-woo' by adding additional information 'National Assemblyman and singer' to the automatic completion query word 'Yoo Seung-woo'.

Next, the list type autocomplete search word is a case where the autocomplete search term includes a detailed list, and the extension information may be information having the same top list as the autocomplete search term. For example, if the autocomplete query is "iPhone background music," it is unclear whether the user is searching for the iPhone background music: Real, Yeah Yeah, or Blue. The extended information management unit 120 may register 'Real, Yeah Yeah, Blue' as detailed information on the 'iPhone background music' as the extended information.

List type autocomplete queries can also be applied to book titles. For example, if the auto-complete query is 'Jungle Greats', the extended information management unit 120 may generate 'Jungle Great Manuscript 1', 'Jungle Manly Manuscript 2', and 'Jungle Manly Book 3' as extension information .

The extended information management unit 120 may store the extended information of the above example in the database 190 by matching the extracted information with the autocomplete search term. The extended information management unit 120 may manage extended information in a meta data format.

The extended information management unit 120 may generate and manage extension information for all the autocomplete search terms having multiple meanings or detailed lists. The extension information may be directly input from the administrator terminal 200 or may be automatically generated by an algorithm input in the service providing server 100.

In accordance with an embodiment of the present invention, the search word matching unit 130 determines whether or not an autocomplete search word generated by a user's input search term has multiple meanings. In the database 190, . The search word matching unit 130 may determine an autocomplete search term having extension information by referring to the extension information list stored in the database 190 by the extension information management unit 120. [

According to an embodiment of the present invention, at least one autocomplete search term generated by a search term input by a user is at least one. That is, a plurality of autocomplete search terms included in the autocomplete list generated by the search term completion unit 110 are. Therefore, the search word matching unit 130 determines whether there is extended matching information for each of a plurality of the autocomplete search terms. There may be an autocomplete search term among a plurality of autocompletion search terms having extension information, and there may be an autocomplete search term that does not exist.

The extended information display unit 140 serves to display extended information corresponding to an autocomplete search term together with an autocomplete search term. At this time, the area for displaying the extension information may be located on the side of the area where the list of the automatic completion term is displayed. In addition, the extended information display unit 140 may display the extended icon on the side of the autocomplete search word in which the extended information exists. The extended information display unit 140 may obtain information on which of the autocomplete search terms have the extended information through the extended icon.

The extended information display unit 140 may not display extension information of all the autocomplete search terms in which extension information exists, but may display only extension information for one autocomplete search term. As described above, there may be a plurality of autocomplete search terms corresponding to the search term entered by the user, and the search term completion unit 110 provides a plurality of autocomplete search terms as an autocomplete list. The extension information display unit 140 can display only the extension information for one autocomplete search word because confusion may occur when the extension information for a plurality of autocomplete search words is displayed at a time.

The extended information display unit 140 may display the extended information for the automatic completion search in which the user's selection action exists in the auto-complete list. For example, the extended information display unit 140 may display extended information for an autocomplete search term in which a user's mouse pointer is located. If the mouse pointer of the user is not located in any of the autocomplete search words, that is, if there is no user's selection, the extended information display unit 140 displays the extended information of the autocomplete search word located at the top of the auto- can do.

The search word determination unit 150 receives the user's extended information selection signal and determines an extended search term based on the autocomplete search term and the extended information. The search word determining unit 150 may apply the method of determining the extension information differently according to the characteristics of the autocomplete search word and the extension information. For example, the search term determiner 150 may determine a search term combining an additional keyword that clarifies the meaning of the autocomplete search term as an extended search term when the autocomplete search term has multiple meanings. Alternatively, the search word determining unit 150 may determine only the extended information excluding the autocomplete search term as the extended search term.

For example, if the extension information includes information about a movie vertical service or a travel vertical service for an autocomplete search term having multiple meanings such as 'Moulin Rouge', the search term determiner 150 may combine keywords for a vertical service You can decide to expand your search term to 'Moulin Rouge' or 'Travel Moulin Rouge'. For example, when a user selects extension information showing a movie vertical service, the extended search term becomes 'movie moulin Rouge', and an integrated search is performed using an expanded search term to provide only information about the movie Moulin Rouge as search results can do.

In another example, if the extended information is related to the iPhone background music such as Red, Yeah Yeah, and Blue, the search word determining unit 150 may determine the keyword 'music Red', 'music Yeah Yeah ', and' Music Blue 'as extended search terms. When the user selects the extension information about Red, the extended search term becomes 'music red', and the integrated search is performed using the extended search term, so that only the information about the music Red can be provided as a search result.

Finally, the search result adjustment unit 160 may adjust the ranking of the search results according to the degree of matching with the extended information among the results searched with the extended search term. In the above example, when the user selects Moulin Rouge of the movie vertical service among the extended information, the Moulin Rouge result retrieved from the movie vertical service may be located at the highest position.

If there is no vertical service corresponding to the extended search term, the search result adjustment unit 160 may sort and provide the search results in the order of higher degree of matching with the extended information.

FIG. 4 illustrates an example of displaying an automatic completion keyword and extended information according to an embodiment of the present invention.

Referring to FIG. 4, the user can know that only 'berak' is entered in the search window s1 as a search term. The search term completion unit 110 completes the input text and generates an autocomplete list including autocomplete search terms such as 'Veracruz, Veracruz 2014, Veracruz Follow-up, ...' . The search word matching unit 130 determines whether there is an autocomplete search term in which at least one of the autocomplete search terms in the autocomplete list exists. In one embodiment of the present invention according to FIG. 4, 'Veracruz' in the list of the autocomplete search terms may have the extended information 'car vera cruise' and 'travel vera cruise'.

Then, the extended information display unit 140 displays the extended information in the extended information area s3. The extended information display unit 140 may display extended information on a side of an area in which an autocomplete search word is displayed, as in the embodiment of FIG. As shown in FIG. 4, the extended information display unit 140 can select whether it is Veracruz of the automobile vertical service or Veracruz of the travel vertical service in order to clearly respond to the search intention of the autocomplete search word Veracruz The extension information can be provided. As shown in FIG. 4, the extended information display unit 140 may display the information corresponding to the vertical service among the extended information as icons i2-1 and i2-2.

The extension information display unit 140 may display the extension icon i1 next to the autocomplete search term in which the extension information exists. In one embodiment of the invention according to FIG. 4, the expansion icon may be in the shape ' ' '. The user can see the '>' icon to see that he / she has the information about the rk extensions of the corresponding autocomplete query. When the user places the mouse pointer on an autocomplete search word displayed with an expansion icon, extension information of the autocomplete search term may appear on the side.

In the embodiment of FIG. 4, when the user selects the extension information for Veracruz of the automotive vertical service, the search term determining unit 150 determines the extended search term as 'car veracruz' and performs an integrated search using the extended search term do.

That is, the Seoul weather information about the auto-complete keyword 'Seoul weather' can be directly provided as extended information.

11 is a flowchart illustrating a method of providing extended information according to an embodiment of the present invention.

11, the extended information management unit 120 of the service providing server 100 according to the embodiment of the present invention stores extension information matched with an automatic completion query in a database (S11).

When the user inputs a search word into the search window using the user terminal 300 in step S21, the search word completion unit 110 of the service providing server 100 receives the search word input up to this point in step S12, (S13).

Next, the search word matching unit 130 determines whether there is extension information matched with the autocomplete search term included in the autocomplete list (S14). The extension information display unit 140 displays an extension icon next to the autocomplete search term in which the extension information exists (S15), and displays extension information of the autocomplete search term located at the top of the autocomplete list (S16). If the extension information does not exist in the topmost autocomplete search word, extension information of the top-ranked autocomplete search word is displayed while the extension information exists.

When the user places the mouse pointer on the autocomplete search word displayed with the expansion icon (S22), the extension information display unit 140 displays extension information of the autocomplete search term where the mouse pointer is located (S17).

When the user selects extension information corresponding to the search intention among the extension information (S23), the search term determiner 150 determines the extended term and performs the search using the extended term (S18).
