The present invention relates to a method and system for effectively providing search results by referring to local information related to a searcher in response to a search request from the searcher through a communication network, and more particularly to a method and system for selecting and effectively arranging search items related to search information for searching of the searcher, in providing Internet search results in response to a keyword input by the searcher.
Today, with rapid development of communication networks such as Internet, information searching through the communication network is very widely used.
As the Internet has a close relation with the whole of our everyday lives, it has now become frequent that we search local living information related to the region where we lives, through the Internet. But, website information provided to a searcher through the Internet is so massive that it has become very difficult for a searcher to determine how to find out the website where information really wanted by a searcher is stored, among the search results.
For example, suppose a case that a searcher who lives in “Samsung-dong, Gangnam-gu, Seoul” inputs a keyword “dental clinic” to search a dental hospital in an Internet search engine in order to receive dental service. In that case, according to the prior art, since not knowing local information regarding the searcher, the Internet search engine server only provides search results in which local information of the searcher is not reflected, to the searcher. Namely, for the search results provided to the searcher, not only the dental clinics located in “Gangnam-gu, Seoul”, but also the dental clinics located in Busan or even in Jeju-do are provided as the search results. Further, since local information of the searcher is not reflected at all in the search results, a search item for the dental clinic located, far distant from the location of the searcher might be arranged as top-ranking search results, while a search item for the dental clinic located close to the location of the searcher might be arranged as low-ranking search results.
Also, suppose that the searcher inputs a keyword “dental clinic <AND> Gangnam-gu” into an input command window of the Internet search engine to find out a dental clinic located in the neighborhood of the searcher' home. Then, on the search result screen provided to the searcher, a plurality of search items related to the keywords “dental clinic” and “Gangnam-gu” are displayed. Among the search items, there exist search items regarding the dental clinics really located in Gangnam-gu, but a plurality of search items regarding the dental clinics that have nothing to do with the Gangnam-gu might be displayed due to limitation of the keyword search method. Also, even in case of the dental clinics really located in Gangnam-gu, if the dental clinic does not include information “Gangnam-gu” at its web page, such dental clinic might not be searched through the Internet searching.
Therefore, there exists inconvenience that a searcher should refer to and check the search items case by case, by making a considerable effort to find out information about the region desired by a searcher.
To improve such inconvenience, lots of methods for effectively searching and arranging a plurality of items so that a searcher may search, in the easier and faster manner, information about the region desired by a searcher, have been suggested.
If a searcher clicks the desired category by referring to a category's title among the category lists of
According to the prior art, to get a searcher to be able to search desired local information among the website search results, a method wherein a searcher inputs desired local information for searching, on the screen of
Namely, according to the prior art, to get a user to carry out Internet information search related to a predetermined local information, a method wherein a user selects a category (for example, real estate, hospital, etc.) to which information to be searched belongs, and then delivers local information to the Internet search engine, has been used.
But, in the method for providing local information search results according to the foregoing prior art, there exists inconvenience that a searcher should search local information by passing through a plurality of steps and a searcher should input desired local information for searching together with a keyword. Therefore, for a searcher who intends to repeat information searching with different keywords regarding the same region, or to search local information whenever necessary, there exists inconvenience that a searcher should designate a region for searching every time upon searching.
It is, therefore, an object of the present invention to provide more useful information to a searcher by providing search results with reference to local information related to the searcher when providing Internet search results to the searcher.
It is another object of the present invention to get the searcher to easily search information related to local information without inputting local information whenever the searcher searches information related to local information.
It is still another object of the present invention to get the searcher to search information regarding a region related to a region of interest in an easier and faster manner.
It is further still another object of the present invention to provide local information searching related to a keyword, to the searcher through a variety of search item arranging methods.
It is another object of the present invention to effectively provide local advertising effect to a network information provider through local information search results.
It is still another object of the present invention to provide customized local information that is fit for local characteristics of the searcher.
It is further still another object of the present invention to provide advertisement opportunity through local information search results, even to a network information provider of the region where there is no website.
To achieve the foregoing objects and to resolve the problems of the prior art, there is provided a method and system for generating a search result list based on local information to provide search results related to local information for searching by referring to local information for searching designated in advance by a searcher, in response to a search request through a communication network.

According to aspect of the present invention, there is provided a method for providing local information search results in response to a search request input through a communication network by a searcher, the method comprising the steps of: receiving local information for searching from the searcher and storing the received local information for searching, receiving a request for a local advertisement related to local information, from a network information provider, maintaining a plurality of search items related to a keyword, in which the search items are related to the local information and the network information provider in response to the request for the local advertisement, receiving a search request from the searcher, identifying at least more than one search item related to the keyword that meets the search request and selecting a search item related to local information matched to the local information for searching and the network information provider, among the identified search items, and arranging at least a part of the search items according to a predetermined search item arranging method in arranging the selected search items.
According to another aspect of the present invention, there is provided a method for providing local information search results in response to a search request input through a communication network by a searcher, the method comprising the steps of: receiving local information for searching from the searcher and storing the received local information for searching, maintaining a database including a plurality of search items related to a network information provider, in which a predetermined local keyword is selected among keywords and the search items are related to the local keyword and the local information related to the network information provider, receiving a search request from the searcher, if the keyword that meets the search request is the local keyword, identifying search items related to the local keyword and selecting a search item related to local information matched to the local information for searching, among the identified search items, and arranging at least a part of the search items according to a predetermined search item arranging method in arranging the selected search items.
According to another aspect of the present invention, there is provided a system for providing local information search results in response to a search request input through a communication network by a searcher, the system comprising: a local information processing part for receiving local information for searching from the searcher and storing the same, a search request receiving part for receiving a search request from the searcher, a storing part for storing a plurality of search items related to a network information provider and relating the search items to a keyword and local information related to the network information provider, a search performing part for identifying search items related to a keyword that meets the search request and selecting a search item related to local information that meets the stored local information for searching, among the identified search items, in response to the search request, and a search results providing part for arranging the selected search items according to a predetermined search item arranging method.
A preferred embodiment of a method and system for providing local information search results will now be described in detail with reference to the accompanying drawings in the following.
On the first place, at the step of S310, local information for searching is received from a searcher and the received local information for searching is stored.
According to the present invention, a searcher does not input local information of his interest for searching every time upon searching, but input only one time, initially, the local information for searching. Then the input local information is stored by a local information search results providing system and maintained as the local information for searching related to the searcher. Therefore, even in case the searcher accesses to the local information search results providing system to input a keyword without the local information for searching next time, the local information search results providing system provides a variety of local information search service to the searcher by automatically referring to the stored local information for searching.
At the step of S311, the local information search results providing system provides, to the searcher, a search configuration setting screen in which a searcher can set a variety of search configurations for search results.
An example of the search configuration setting screen is shown in
As shown in
As shown in
The cookie file 520 is a special text file stored at a hard disk of the terminal 510, which is a client terminal, by the local information search results providing system or other website in case a searcher accesses to the local information search results providing system 540 or other website through the terminal 510. In a HTTP (Hyper Text Transfer Protocol) protocol used for access to the websites, each request for the website is all independent of the other requests. Therefore, the local information search results providing system cannot have any information whatsoever as to which page it has transmitted previously to the terminal 510 of the searcher or which page it has performed together with the terminal 510. Accordingly, the cookie file is provided to get each request that is independently processed in this manner to be related each other, and such cookie file plays a role of getting the local information search results providing system 540 to store information regarding the searcher at the searcher's terminal. Of course, the cookie file can be used for detecting local information for searching related to the searcher.
By storing local information for searching at the searcher's terminal in form of a cookie file in this manner, even in case the searcher makes a search request in the same manner as the general Internet searching, the Internet search engine can provide more useful information to the searcher by referring to the local information for searching stored in the cookie file of the searcher's terminal. Namely, according to the present embodiment, since additional procedures such as “log in” is not required, local information that is both transparent and useful to the searcher can be provided.
For another embodiment of the present invention, it may be possible to perform search configuration setting including the local information for searching after a searcher logs in the local information search results providing system. Since the searcher inputs local information for searching related to the searcher after logging in the local information search results providing system, the local information search results providing system can know information about the searcher and store the local information at a predetermined database in relation with the searcher's information. Also, if the searcher carries out searching after logging in the local information search results providing system, the local information search results providing system can identify the searcher through the log-in procedure, and obtain the local information for searching stored as search configuration setting information of the identified searcher, so that, the local information search results providing system can reflect the local information for searching when providing the search results to the searcher.
Though the local information for searching can be reflected only in case the searcher makes a search request after the log-in procedure according to the present embodiment, it is also possible to reflect the local information upon providing the search results even in case the searcher makes a search request using other PC (for example, in case the searcher uses a PC in a PC room) as far as the searcher sets the local information for searching only one time.
For still another embodiment for storing search information according to the present invention, there exists a method wherein a predetermined client program is installed in the searcher's terminal and the client program sets the region of interest with respect to local information for searching. If the searcher accesses to the local information search results providing system through the searcher's terminal to perform searching, the client program provides the local information of the searcher to the search engine server, so that the search engine server can obtain the local information for searching.
Although the foregoing three embodiments of the present invention are limited to the case of receiving the local information of the searcher from the searcher, it may be also possible to extract the local information of the searcher from other information of the searcher and store the same in the local information search results providing system, a cookie file of the searcher's terminal, or a file related to the client program installed in the searcher's terminal in case the searcher does not explicitly input the local information of the searcher.
In the above, the local information input by the searcher is the information regarding the region that is wanted to be considered by the search engine server upon searching afterward by the searcher. For example, office workers who spend most of time at a company may input local information of the company for the local information, while housewives who spend most of time at home may input local information of home for the local information.
For example, in case the searcher inputs his telephone number (not shown in
Similarly, it may be possible to extract the local information on the basis of the company's name input by the searcher. For example, if a database regarding address for each company is provided, it is possible to extract the local information of the searcher on the basis of the company's name input by the searcher. According to the present embodiment, even if the searcher does not explicitly input the local information, it is possible to provide, to the searcher, the search results reflecting the local information that is related to the searcher.
In the following, the step of S320 and the subsequent steps will be described.
The step of S320 maintains a database including a plurality of search items related to the network information provider. At the present step, the website of the network information provider is related to the search item.
The local information region 650 includes local information related to a website of the network information provider related to the search item. If the local information for searching designated by the searcher is in agreement with the local information within the search item, the search item including such local information is identified as a relevant search item that meets a search request by the searcher.
For an embodiment for designating the local information, the network information provider can input the local information related to the website of its own when registering the website at a storing part of the local information search results providing system, and the local information search results providing system can store the input local information at the local information region of the search item.
For another embodiment, even though the local information is not explicitly received from the network information provider, the local information search results providing system may possibly extract the appropriate local information by referring to content of the website of the network information provider, and store the same at the local information region of the search item. For example, if the network information provider is a “dental clinic” and the position information of the clinic is described in website of the dental clinic, the local information search results providing system may automatically extract the position information and store the same at the local information region. Unlike the above example, if the network information provider inputs information related to the region such as a telephone number, a trade name, an address, and the input information is stored in the local information search results providing system, it may be also possible to extract the local information of the network information provider on the basis of that information. For example, since a telephone exchange number of a telephone number is determined according to regions, if a database that includes local information according to the telephone exchange number is provided, the telephone exchange number input by the network information provider is compared with the above database, so that the local information of the network information provider can be obtained.
According to still another embodiment of the present invention, at the step of S320, a predetermined keyword where region is meaningful is selected in advance as a “local keyword”. For example, since the keywords such as “psychology”, “HTML” are not related very much to the local information while the keywords such as “kindergarten”, “real estate”, “hospital”, and “auto maintenance” are possibly considered to be highly related to the local information, such keywords are selected in advance as the local keywords and stored in a predetermined database. Therefore, if the searcher inputs a keyword “psychology”, the search results that reflect the local information of the searcher are not provided to the searcher, but if the searcher inputs a local keyword “hospital”, the search results can be provided, to the searcher, in an order of the same region as the searcher, and the neighboring region of the searcher, by reflecting the local information of the searcher.
According to an embodiment of the present invention, the local keyword can be determined differently region by region with consideration of local characteristics. For example, in case of Ganggyeong, Jeollanam-do well known as a producing center of its salted sauce, the “salted sauce” may be a meaningful local keyword for the “Ganggyeong” province, but in case of other provinces, it may not be pertinent that the keyword “salted sauce” is selected as a local keyword. In case of “Ganggyeong” province, since there are lots of enterprises related to the “salted sauce”, users in “Ganggyeong” province frequently perform searching using the keyword “salted sauce”, therefore, it is necessary to subdivide the region and provide, to the searcher, the search results reflecting the local information of the searcher. But, in case of other province, such necessity may be low. Accordingly, it is more preferable to differently select the local keyword considering the local characteristics region by region.
At the step of S330, the local information search results providing system receives a search request from the searcher. If the searcher accesses to the local information search results providing system to input a keyword or information related to the keyword, the keyword is delivered as a search request packet to the local information search results providing system.
At the step of S340, the local information search results providing system identifies at least more than one search item related to the keyword that meets the search request in response to the search request from the searcher. When searching the search item that is in agreement with the keyword received from the searcher, the local information search results providing system refers to the local information of the searcher stored in the step of S310. Namely, in case the local information for searching is stored in the cookie file, the local information search results providing system refers to the cookie file, and in case of the embodiment based on the log-in system, the local information search results providing system refers to the local information for searching stored in it in relation to the searcher. In the meantime, in case the client program is installed in the searcher's terminal, the client program simultaneously provides the local information for searching when providing the search request to the local information search results providing system.
For still another embodiment, in case the step of S320 selects a predetermined keyword where region is meaningful as the local keyword and connects the local keyword to the search item, the step of S340 judges whether the keyword that meets the search request from the searcher is the local keyword, and if the keyword is judged to be the local keyword as a result of judgment, the step of S340 can identify the search item related to the local keyword. Namely, if the keyword input by the searcher is not the local keyword, the search results are provided in the same way as the prior art, and if the keyword is the local keyword, the search results are provided with reference to the local information of the searcher.
The local information search results providing system selects the search item related to the local information that meets the local information for searching stored at the step of S340, among the identified search items. For a preferred embodiment, the “local information that meets the local information for searching” may include not only the local information that is in agreement with the local information for searching but also the local information closely related to the region to be searched as well. Namely, in case the local information for searching is “Gangnam-gu, Seoul”, the searching items that are related to not only “Gangnam-gu, Seoul” but also “Seocho-gu, Seoul” which is its neighboring region, may be selected together. Also, for example, in case there is no search item that is related to the local information “Gangnam-gu, Seoul” with respect to a specific keyword, the search item that is related to the local information “Seocho-gu, Seoul” which is the neighboring region of “Gangnam-gu, Seoul”, may be displayed. Also, “closely related local information” may include not only the local information regarding the neighboring region geographically but also the local information closely related due to other reasons such as cultural, social, or environmental reasons.
The step of S350 which arranges the search items selected at the step of S340, arranges the search items according to a predetermined search item arranging method. According to the present invention, it is possible to arrange the selected search items according to a variety of arranging methods. If a search request is received from the searcher, the search results are provided to the searcher on the basis of the local information for searching related to the searcher. If a keyword “dental clinic” is input by the searcher and the local information for searching related to the searcher is “Gangnam-gu, Seoul”, the search items whose local information is “Gangnam-gu, Seoul” are displayed at the upper part on the screen and the “dental clinic”-related search items related to the rest regions are displayed at its lower part, among the found search items.
According to further still another embodiment of the present invention, after the search items having the local information that is in agreement with the “Gangnam-gu, Seoul” are displayed, the “dental clinic” information related to the neighboring region (for example, Seocho-gu, Seoul) of the “Gangnam-gu, Seoul”, is subsequently displayed. Therefore, according to the present embodiment, even if the searcher does not separately input the local information when making a search request at the Internet search engine server (namely, even if the searcher inputs simply the “dental clinic”), the search results where the local information of the searcher is reflected can be obtained.
According to an embodiment of the present invention, in response to a search request from the searcher, the search item that is highly appraised by users or the web page of the network information provider who has paid much for its advertisement charge will be preferentially arranged and provided to the searcher, among the search items that are in agreement with the local information.
The arranging method of the “keyword banner 710” is to display the search items in form of a banner having a predetermined size manufactured with a flash animation or an image, at the first page where the search items of a specific keyword are displayed as shown in the right side of
The arranging method of the “knowledge search results 720” is to represent, in form of questions, the website and the characteristics of the network information provider. In this arranging method, the keyword and the question itself can be linked to the website of the relevant enterprise and the search items are positioned at the uppermost part of an integrated search results and an advertisement region is provided up to a predetermined ranking for each keyword.
The arranging method of the “sponsor link 730” is to display a title and a description of the website at the first page of the specific keyword search results. In this arranging method, the search items are positioned at the uppermost part of the integrated search results and the directory search results, and the advertisement region is provided up to a predetermined ranking for each keyword.
The arranging method of the “category 740” is to classify the search items into a plurality of categories depending on content of the web page related to the search item and display a list of the search categories, in displaying numerous search items related to the keyword. For example, if the keyword “dental clinic” is input, the information of the relevant region is displayed in form of a category such as “dental surgery”, “dental clinic”, “dental hospital”, and the like.
The arranging method of the “plus site 750” is to show additional information and an image of the web page together with the search results. In this arranging method, publicity content directly described by the network information provider is introduced and the registration process is swiftly processed, whereby easy and fast registration service is provided.
For a preferred embodiment, it is possible to get the network information provider of the web page related to the search item, to select the search item arranging method and arrange the search item according to the selected arranging method.
For another embodiment of the local information search results providing system shown in
For the method for arranging the selected search items, one among the above described keyword banner, the knowledge search results, the sponsor link, the category, and the plus site, may be used.
The present embodiment which includes the local advertisement, additionally includes the step of determining a predetermined advertisement charge for the local advertisement, and the advertisement charge may be determined differently depending on the local information related to the local advertisement request. For example, in case of the keyword “plastic surgery”, since it is expected that search frequency for the local information of “Gangnam-gu” where the plastic hospitals are concentrated much more, is much greater than the search frequency for other city or other-gu, the advertisement charge may be determined with consideration of the advertisement effect for each region. For another embodiment, the advertisement charge may be determined depending on a size of the region related to the local advertisement. For example, the advertisement charge may be differently estimated depending on whether it is a local advertisement for -gu or it is a local advertisement for -dong. For still another embodiment of the present invention, if there is no local advertisement for unit of -dong when the search results are provided to the searcher, the local advertisement for unit of -gu to which its dong belongs, is displayed.
Also, since the advertisement effect may differ depending on the search item arranging method, the advertisement charge may be differently determined depending on the search item arranging method.
For another embodiment in determining the advertisement charge, the advertisement charge may be determined with consideration of frequency of page view or reference of the search item selected for the arrangement.
According to a preferred embodiment of the present invention, only at least a part of a search list among the identified search items is preferentially arranged according to the search item arranging method of the present invention, and the rest search items are arranged according to the arranging method independent of the above method. For the independent arranging methods, a number of references of the website of the network information provider related to the search item, usefulness of the information posted on the website, degree of perfection of the website, an order of the website's name, appraisal of a user, may be considered.
According to another embodiment of the present invention, it is possible to receive “network information” from the network information provider to register the information in the database even if there is no website of the network information provider, and to relate the registered network information to the search item. For the network information, there exist a trade name, a telephone number, a category, an address, map search information, business explanation, image information, a variety of additional information of the network information provider. If the local information of the network information provider is matched to the local information of the searcher each other upon search request by the searcher, it is possible to provide the network information to the searcher. Therefore, according to the present invention, it is possible to provide an advertisement opportunity through the local information search results, even to the small-scale network information provider who has no website in its region.
