Description

Internet information search system and special searching a regional information and method for searching the internet information using the same}

The present invention relates to an Internet information retrieval system, and more particularly, to an Internet information retrieval system exclusively for local information retrieval, which makes it easier to retrieve information of a specific area widely distributed on the Internet web. Furthermore, the present invention relates to a method for retrieving Internet information using such an Internet information retrieval system dedicated to local information retrieval.

In recent years, with the explosive growth of Internet web sites, various kinds of Internet information retrieval systems have been developed and widely distributed to systematically search and output information about these web sites.

Such conventional Internet information retrieval systems are largely classified into keyword type internet information retrieval systems, directory type internet information retrieval systems, meta type internet information retrieval systems, and the like.

In general, the conventional keyword type internet information retrieval system refers to an information retrieval system for retrieving relevant information input by a user by constructing a database of specific phrases of web pages distributed in the Internet network, and commercializing using this method. AltaVista (http://www.altavista.co.kr), Lycos (http://www.lycos.co.kr), Naver (http://www.naver.com), Simmany (http://simmany.chollian.net) and Kacine (http://www.kachi.com).

In addition, the conventional directory-type Internet information retrieval system refers to an information retrieval system that classifies web pages distributed in the Internet network into several directories set in advance, and retrieves the corresponding information input by the user. Commercialized Internet information retrieval system used is Yahoo (http://www.yahoo.co.kr), Galaxy (Gaalaxy, http://www.einet.net).

In addition, the conventional meta-type Internet information retrieval system refers to an information retrieval system that retrieves other information retrieval systems at the same time based on the corresponding information input by the user. (Savvysearch, http: //guaraldi.cs.colostate.edu.2000), MetaSearch (http://www.metasearch.com), and Miss Dazzini (http://mochanni.com).

Recently, with the rapid increase of the above-mentioned Internet information retrieval system, there is a frequent occurrence of using the Internet information retrieval system to search for specific local information, for example, "location of a bookstore located in Ssangmun-dong area, Dobong-gu, Seoul". have.

However, when using the keyword type, directory type, and meta type internet information retrieval system mentioned above as a search tool, it is very difficult to accurately obtain information of a specific area that a user actually wants.

There are various reasons for this. For example, in the case of the keyword type internet information retrieval system, the search results are so large that one or more search results are necessary. If the user uses this keyword type information retrieval system as a search tool, the user must bear the inconvenience of having to re-search the desired location of the bookstore located in the Ssangmun-dong area of Dobong-gu, Seoul. .

In order to overcome this problem, a user has no choice but to use a complex expression when inputting a keyword. In this case, the user must bear another inconvenience of knowing the expressions of the corresponding Internet search system.

At this time, if there is a slight error in the user's expression, the problem is that the search itself is not executed, and even if the search is executed, the problem is that the search results are excessively related to the subject that the user is looking for. Can be.

As another example, in the above-described directory type internet information retrieval system, the divided directories themselves are so extensive that it takes a lot of time to collect, verify, and classify data. If the user uses this directory type information retrieval system as a retrieval tool, the user must bear the problem of not being able to obtain the information of the specific area that he / she wants quickly and accurately like the keyword type internet information retrieval system mentioned above. .

In addition, the meta-type Internet information retrieval system described above basically searches several search engines, and the search speed itself is very slow, and the search results are extracted more than necessary. If the user uses the meta-type internet information retrieval system mentioned above as a search tool, the user does not acquire the information of a specific area desired by the user quickly, like the keyword type and directory type internet information retrieval system mentioned above. You must accept the problem.

Accordingly, an object of the present invention is to limit the overall search range of the information retrieval system to an area related to local information, thereby inducing a user to more accurately search for information of a specific area desired by the user.

Another object of the present invention is to change the interface between the user and the information retrieval system from the conventional "user input type" to "user attracted type", so that the user can obtain the information of the specific area desired by the user without using a complicated calculation expression. It is to make searching more convenient.

Another object of the present invention is to change the operation method of the information retrieval system, for example, by causing the information retrieval system to calculate the user's selection according to a preset equation, thereby reducing the overall operation time of the information retrieval system, Through this, the user can be induced to search for the information of the specific area desired by the user more quickly.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

16 is an exemplary view showing a display state of a search web page according to another embodiment of the present invention.

In order to achieve the above object, in the present invention, such as a web search robot, a web information register, a web information indexer, an index database (hereinafter referred to as "D / B") searcher, interface manager, etc. Disclosed is an Internet information retrieval system exclusively for local information retrieval made of a combination. In this case, the web search robot, the web information register, and the web information indexer serve to store accurate local information in the index D / B so that the full-scale Internet local information search process can be performed by the index database searcher and the interface manager. Lay the foundation.

In the state where the D / B base of the local information is prepared, the interface manager hierarchically lures the user's local name selection process performed in the local name input window of the search web page, and enters the main word input window of the search web page. Attracting the user's main word selection process hierarchically, Determining the domain name of the user input through the domain name input window of the search web page, Query object of the user input through the keyword input window Proceed with determining the keyword.

Thereafter, the index D / B searcher searches a list of previously stored local information based on the query target region name, query subject key word, query target domain name, and query target keyword, which are determined by the interface manager, and extracts a series of search result documents. In addition, by outputting the search result document by priority, the user can eventually acquire the local information he / she wants to find more quickly and accurately.

In the case of the present invention, since the overall search range of the system is limited to the area related to the local information, and also, the interface between the user and the system is changed from the conventional "user input type" to "user attracted type". When this is achieved, the user can obtain the advantage of more conveniently searching for the information of the specific area desired by the user without using complicated calculation expressions.

Hereinafter, an Internet information retrieval system exclusively for local information search and an internet information retrieval method using the same according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the Internet information retrieval system 200 exclusively for local information search according to the present invention includes a web search robot 80, a web information register 70, a web information indexer 50, and an index D /. It consists of a combination of the B searcher 30, the interface manager 20, and the like.

In this case, the web search robot 80 continuously searches web pages distributed in the Internet network 300, reads the contents of web pages visited by itself, and visits all websites linked to each web page in turn. It collects the main contents including the URL (Uniform Resource Locator) of the web pages.

Here, the web search robot 80 of the present invention does not collect the contents of all the web pages distributed in the Internet network 300, but only the contents of the local record web pages in which the area names are recorded. Optionally collect. In this case, the Internet information retrieval system 200 according to the present invention can significantly limit its entire search range to a region related to local information, and eventually, a user can search for information of a specific region desired by the user more quickly and accurately. Advantages can be obtained.

In this case, since the local record web pages collected by the web search robot 80 are generally made of various types of document writers, a process of matching them into one unified document form is necessary.

In this case, the web information register 70 for exchanging information with the web search robot 80 filters the local record web pages collected by the web search robot 80 and converts them into a single document form. Perform.

When the filtering process is completed, the web information register 70 loads and registers local record web pages converted into a unified document form into the buffer data space 60.

At this time, the web information indexer 50 exchanging information with the buffer data space 60 serves to index and record the local record web pages registered in the buffer data space 60. In this case, the web information indexer 50 first assigns a series of IDs to the local record web pages registered in the buffer data space 60, and then stores them in the index D / B 40.

Subsequently, the web information indexer 50 uses, for example, an index method such as an inverted index file method, a string match method, a signature file method, and the like. It extracts the main items of the recorded web pages, for example, region name, subject word, domain name and keyword, and corresponds to each web page to which they belong for the extracted region name, subject word, domain name and keywords. Proceed with the process of granting the ID.

After this process is completed, the web information indexer 50 generates a series of local information lists by arranging the region name, the subject word, the domain name, and the keyword to which the ID is assigned, and then indexes the local information list by index D / B ( To 40).

On the other hand, as shown in the figure, the local information search dedicated Internet information search system 200 of the present invention can interface with the user 100 through a search web page 10 linked to the Internet network 300 have. In this case, the interface manager 20 exchanging information with the search web page 10 updates the display state of the search web page 10 in various ways according to the query word selection situation of the user 100, thereby allowing the user 100 ) To induce hierarchical query selection. Details thereof will be described later.

Here, the index D / B searcher 30 exchanging information with the interface manager 20 may determine a user's query word input via the search web page 10 and the interface manager 20 as described above. It operates by extracts a series of search expressions.

When the search expression extraction process is completed, the index D / B searcher 30 searches the aforementioned list of local information according to the search expression, extracts a series of search result documents, and prioritizes the extracted search result documents. Determine and output the search result document to the interface manager 20. In this case, the interface manager 20 displays the search result document output from the index D / B searcher 30 to the user through the search web page 10 to thereby quickly obtain local information that the user wants to find. Do it.

Hereinafter, an Internet information retrieval method using the Internet information retrieval system 200 dedicated to local information retrieval having the above-described configuration will be described in detail.

In the state where the search web page 10 shown in FIG. 2 is displayed, the user 100 performs a series of local information search processes by operating a mouse, a keyboard, and the like.

In this case, as shown in FIG. 3, the interface manager 20 firstly hierarchically lures a local name selection process of the user 100 performed in the local name input window 2 of the search web page 10. Then, a process of determining a desired query target region name is performed (step S10).

To this end, first, as shown in FIG. 4, the interface manager 20 proceeds to determine whether the area name input window 2 is clicked by the user 100 (step S10a).

In this case, when the region name input window 2 is clicked by the user 100, as shown in FIG. 5, the interface manager 20 stores various region name menus stored in its D / B 21. For example, the process of displaying the list of local names 2a on which all, Seoul, Busan, Daegu, Gwangju ……, etc. are listed through the search web page 10 is performed (step S10b).

Here, the interface manager 20 of the present invention hierarchically stores and manages the region name list in its D / B 21. That is, the interface manager 20 stores and manages the region name list 2a in which "All, Seoul, Busan, Daegu, Gwangju ……" are listed at the top of the list of all region names, and the next step of the region name list. Stores and manages a list of region names that list the administrative regions below the list of cities and provinces mentioned above, such as "Gangseo-gu, Dobong-gu, Eunpyeong-gu ...". The stratification of this list of regional names can be broken down to the required sub-administrative districts, such as coun- tries, towns and villages.

On the other hand, in the above-described step S10a, when the region name input window is not clicked by the user 100, the interface manager inputs another input window other than the region name input window 2, for example, a main word input window 3 and a domain name input. It is determined whether the window 4, the keyword input window 5, or the like has been clicked (step S10c).

At this time, if another input window other than the region name input window 2 is clicked, the interface manager 20 stores all the region names listed in the region name list 2a regardless of the intention of the user 100, thereby Are all included in the final query target region name (step S10k). Accordingly, the problem of missing the local name from the final search target query word due to a mistake of the user 100 is solved in advance.

However, as a result of the above-described determination of step S10c, if no input window other than the region name input window 2 is clicked, the interface manager 20 may, for example, refer to the guide message display window 6, for example, "the name of the region to search for. Display a guide message ", and the flow is returned to the above-described step S10a, thereby inducing the user to select a local name once again (step S10d).

On the other hand, as shown in FIG. 4 described above, after step S10b is performed, the interface manager 20 determines whether the user 100 selects a specific region name from among the region names displayed in the region name list 2a. The judgment process is performed (step S10e).

At this time, when a specific region name, for example, "Seoul" is selected by the user 100, the interface manager 20 determines that the list of region names 2a including the specific region name, for example, "Seoul" is the entire region name. The process of determining whether or not it is the last step of the list is performed (step S10f).

Here, if the area name list 2a including Seoul is the last step of the entire area name list, the interface manager places "Seoul" in the D / B area 21 of the user 100 for the final query target area name. And a guide message such as "You have selected Seoul area" is displayed through the guide message display window 6 (steps S10g and S10h).

However, if the region name list 2a including Seoul is not the last stage of the entire region name list, and the region name list indicating the lower administrative region is further stored, the interface manager 20 performs the above-described step S10b, 6 and 7, the user 100 narrows the region range he / she wants to search to, for example, “Seoul → Gangseo-gu → Hwagok-dong”.

As such, in the case of the present invention, the user's selection of the local name is hierarchically attracted by the interface manager 20, so that the interface between the user 100 and the information retrieval system 200 is conventional in " user input type " Since it is changed to "user-attractable type", when the present invention is implemented, the user 100 can more conveniently search for information of a specific area desired by the user without using complicated calculation expressions.

On the other hand, in the process of the above-described step S10e, if the user 100 does not select a specific region name, the interface manager 20 is to be entered by the user 100 all the region name as the query target region name It judges and stores all the region names including "Seoul" as the final query subject region name, and displays a guide message such as "You have selected all regions" through the guide message display window 6 (step S10i). , S10j). Of course, in this case, the interface manager 20 includes not only the region names included in the region name list 2a, but also the region names included in the region name lists 2c and 2f in each step as the final query region names. .

As a result, when all of these steps S10 are completed, as shown in FIG. 8, region names such as Seoul, Gangseo-gu, Hwagok-dong, etc. are displayed on the region name menu windows 2, 2b, and 2d. The name of the region to be queried is saved.

In a state where step S10 is completed through the above-described process, the interface manager 20 may include the region name selection process described above and the process of selecting the main keyword of the user 100 performed in the keyword input window 3 of the search web page. Similarly, by attracting hierarchically, the process of determining the desired subject word desired by the user is performed (step S20).

First, as shown in FIG. 9, the interface manager 20 proceeds to determine whether the main word input window 3 is clicked by the user 100 (step S20a).

In this case, when the main word input window 3 is clicked by the user 100, as shown in FIG. 8, the interface manager 20 stores various main word menus stored in its D / B 21. For example, a process of displaying, via the search web page 10, a list of main words 3a including "all, public institutions, hospitals, restaurants, theaters, ...", etc. is performed (step S20b).

Here, the interface manager 20 of the present invention stores and manages the main word list in a hierarchical manner similar to the list of area names described above. That is, the interface manager stores and manages the main list (3a), which lists "all, public institutions, hospitals, restaurants, theaters,…," etc. at the top of the entire main list, and the next step of the main list A list of the main words indicating the area, for example, "All, Chinese, Korean, Western, ...," etc. are stored and managed. This layering of keyword lists can be freely subdivided up to the required subregions.

On the other hand, in the above-described step S20a, when the main word input window 3 is not clicked by the user 100, the interface manager 20 is another input window other than the main word input window 3, for example, a domain name input window ( 4) It is determined whether or not the keyword input window 5 or the like has been clicked (step S20c).

In this case, when another input window other than the main word input window 3 is clicked, the interface manager 20 proceeds to step S30 to describe the flow and skips the main word input process.

However, as a result of the above-described determination in step S20c, when no input window other than the main word input window 3 is clicked, the interface manager 20 selects the main word to be searched through the guide message display window 6, for example. Display the guide message and return the flow to the above-described step S20a, thereby inducing the user's 100 region name selection process to be performed once again (step S20d).

On the other hand, after the step S20b, the interface manager 20 proceeds to determine whether the user 100 has selected a particular main word among the main words displayed in the region name list 3a (step S20e).

At this time, when a specific main word, for example, "restaurant" is selected by the user 100, the interface manager 20 determines that the main word list 3a including the specific main word, for example, "restaurant" is the last step of the entire main word list. The process of judging whether or not authorization is to proceed (step S20f).

In this case, when the main word list 3a including the restaurant is the last step of the entire main word list, the interface manager stores “restaurant” as the final query subject of the user 100 in its D / B area 31. , Through the guide message display window, displays a guide message such as "You have selected a restaurant" (steps S20g, S20h).

However, if the main word list 3a including the restaurant is not the last step of the entire main word list, and the main word list indicating the lower area is further stored, the interface manager 20 repeats the above-described steps S20b and S20e. 10 and 11, the user 100 narrows the main word range to be searched by, for example, "restaurant → Korean food → meat".

Even in this case, the main manager's selection of the main word of the user 100 is hierarchically attracted by the interface manager 20, so that the interface between the user 100 and the information retrieval system 200 is changed from the conventional " user input type " Since the present invention is implemented, the user 100 can more conveniently search for key word information of a specific region desired by the user 100 without using a complicated calculation expression.

On the other hand, in the process of the above-described step S20e, when the user 100 does not select a specific subject, the interface manager 20 determines that the user wants to input all the subjects as the subject to be queried, "restaurant" In addition to storing all the main words including the final word as the final query target subject, the guide message such as "You have selected all the main words" is displayed through the guide message display window 6 (steps S20i and S20j). Of course, in this case, the interface manager 20 includes not only the main words included in the main word list 3a, but also the main words included in the main word lists 3c and 3f of each step in the final query subject.

As a result, when all of these steps S20 are completed, as shown in FIG. 12, the main menus 3, 3b, and 3d display main keywords such as restaurants, Korean food, meat, and the like. It is stored as a keyword.

In a state where step S20 is completed through the aforementioned process, the interface manager 20 determines the domain name of the query object of the user 100 that is input through the domain name input window 4 of the search web page 10. Proceeds to the process (step S30).

First, as shown in FIG. 13, the interface manager 20 proceeds to determine whether the domain name input window 4 is clicked by the user 100 (step S30a).

In this case, when the domain name input window 4 is clicked by the user 100, as shown in FIG. 12, the interface manager 20 stores various domains stored in its D / B 21. A process of displaying the domain name list 4a on which the name menu, for example, "All, com, net, org, edu, com, or.kr…", etc., is listed through the search web page 10 is performed. (Step S30b).

However, when the domain name input window 4 is not clicked by the user 100, the interface manager 20 clicks another input window other than the domain name input window 4, for example, the keyword input window 5. It is judged whether or not it is (step S30c).

At this time, if another input window other than the domain name input window 4 is clicked, the interface manager 20 proceeds to step S40 to describe the flow later skips the domain name input process.

However, as a result of the above-described determination in step S30c, when no input window other than the domain name input window 4 is clicked, the interface manager 20 uses the guide message display window 6, for example, "the domain name to be searched." Display the guide message ", and the flow is returned to the above-described step S30a, thereby inducing the user to perform the domain name selection process once again (step S30d).

Meanwhile, after step S20b is performed, the interface manager 20 proceeds to determine whether the user 100 selects a specific domain name from among domain names displayed in the domain name list 3a (step S30e). .

At this time, when a specific domain name, for example, "com" is selected by the user 100, the interface manager 20 stores "com" in the user's D / B area 21 as the final query target domain name of the user. Then, a guide message such as "You have selected com as a domain name" is displayed through the guide message display window (steps S30f and S30g).

However, when the user 100 does not select a specific domain name, the interface manager 20 determines that the user 100 wants to input all the domain names as the query target domain name, and includes all of the characters including "com". In addition to storing the domain name as the final query target domain name, a guide message such as "You have selected all domain names" is displayed via the guide message display window 6 (steps S30h and S30i).

As a result, when all of these steps S30 are completed, as shown in Fig. 14, the main menu window 4 displays, for example, a domain name of "com", which is stored as the final query target domain name.

In a state where step S30 is completed through the above-described process, the interface manager 20 determines a keyword to be queried by the user 100 that is input through the keyword input window 5 of the search web page 10. Proceed to step S40.

First, as shown in FIG. 13 described above, the interface manager 20 proceeds to determine whether a keyword is input by the user 100 (step S40a).

At this time, when a keyword, for example, "cold noodles" is input by the user 40a, the interface manager 20 sets "cold noodles" as the final query target keyword of the user 100 in its D / B area 21. And guide message such as "You have selected cold noodles as a keyword" through the guide message display window 6 (steps S40b, S40c).

However, if a keyword is not input by the user 100, the interface manager 20 determines that the user 100 does not want to input the keyword, and through the guide message display window 6, for example, "keyword". Display a guide message, and proceeds to step S50 to describe play (step S40d).

As a result, when all of these steps S40 are completed, as shown in Fig. 14, a keyword "for example, cold noodles" is displayed in the keyword menu window 5, and this keyword is stored as the final query target keyword.

Thereafter, the user 100 clicks the search button 1 displayed on the search web page 10 so that a full-fledged information search process can proceed.

In this case, the index D / B searcher 30 exchanging information with the interface manager 20 may determine the index D based on the query subject region name, query subject key word, query subject domain name, and query subject keyword that have been confirmed through the above-described process. A list of local information stored in advance in / B 40 is searched, a series of search result documents are extracted, and the search result documents are output in order of priority (step S50).

First, as shown in FIG. 15, the index D / B searcher 30 searches the D / B 21 of the interface manager 20 to search the area name of the query to be secured by the interface manager 20 and the query object. The process of checking the key word, the query target domain name, and the query target keyword is performed (step S51).

Through this process, the index D / B searcher 30 recognizes that the query word secured by the interface manager is, for example, "Seoul / Gangseo-gu / Hwagok-dong> restaurant / Korean / Bulgogi> com> cold noodles".

Subsequently, the index D / B searcher 30 searches its own D / B 31, extracts a related topic pre-stored in the D / B 31, and combines the related topic with the query subject topic described above. The process proceeds (step S52).

If the subject to be queried by the index D / B searcher 30 is "Bulgogi," the index D / B searcher 30 may store the related key word stored in its D / B 31, such as "pork ribs, By combining beef ribs, roasted ribs, ...… "with the same query subject as" bulgogi ", the reliability of the search result document extracted afterwards is greatly improved.

Subsequently, when the above-described related subject combining process is completed, the index D / B searcher 30 may be, for example, "Seoul / Gangseo-gu / Hwagok-dong> Restaurant / Korean / Bulgogi (pork ribs, beef ribs, bulgogi stir-fry, ……)> com> cold noodle "or the like is generated (step S53).

Then, the index D / B searcher 30 searches its own D / B 31, finds out which combination rule is set in advance, and performs a final search by this combination rule. Is generated (step S54).

At this time, if the combination rule "to combine the query according to the and formula" is set in advance, the index D / B searcher 30 is "Seoul / Gangseo-gu / Hwagok-dong <and> restaurants / Korean / Bulgogi ( Pork ribs, beef ribs, roasted ribs, ……) <and> com and cold noodles.

As described above, in the case of the present invention, the query combination method is changed so that the information retrieval system calculates the user's selection according to a preset combination rule, thereby reducing the search time of the overall information retrieval system. Encourage faster retrieval of specific local information.

Meanwhile, when the above-described search expression generation step is completed, the index D / B searcher 30 searches a list of local information stored in the index D / B 40 based on the search expression, and sets a series of search result documents. The process of extracting the process proceeds (steps S55 and S56).

In this case, as described above, since the region name, the main word, the domain name, and the keywords to which the ID corresponding to the web pages to which they belong are arranged in the region information list, the index D / B searcher 30 is described above. The search result document extraction process can be performed more quickly.

When the search result document extraction process is completed, the index D / B searcher 30 proceeds to give priority to the search result document (step S57).

In this case, the index D / B searcher 30 may, for example, ask, "Does the query appear in the title of the webpage?", "Is the query close to the beginning of the webpage?" How often does it appear on the page? " The priority of each search result document is determined based on such criteria.

Thereafter, the index D / B searcher 30 proceeds to output the search result documents of which the priority is determined according to the corresponding priority (step S58).

In this case, the search result document output from the index D / B searcher 30 is output to the search webpage 10 via the interface manager 20. As a result, as shown in FIG.
