Description

Dynamic Keyword Extraction and Processing System

In the existing web browser (S230) or the toolbar, when the user inputs a string such as a keyword or a URL in the address bar, only the connection or search for the corresponding site is supported. However, the URL input by the user or the web browser S230 is not used for a new key search or connection to a website by automatically processing the URL string displayed in the address window when the website is accessed. That is, in the conventional method, the URL or keyword inputted by the user was used only for accessing the website, and the URL displayed as a result of accessing the site was only used to indicate the address of the corresponding site, but was not reprocessed. The present invention extracts a keyword from the URL or keyword input by the user and the URL output in the address window when the web browser (S230) is connected to the website, and processes and utilizes the keyword to the related site expected in the future. It provides a way to make navigation and search easier.

In the present invention, a string such as a URL or a keyword that a user inputs in a web browser address window S210 to access a website, and a URL of the corresponding site displayed in the address window while the web browser S230 is connected to the website. We focused on the fact that the user has important information related to the information he is looking for. Typically, a domain name or URL will consist of words that are most relevant to what the site offers. Therefore, by processing URLs that are entered or displayed in the address bar, keywords can be extracted in reverse, and by reprocessing the extracted keywords in various forms, users can prepare in advance the search words that users will use or the related sites that they expect to navigate. have. The present invention proposes a method of extracting a keyword from a URL, a method of reprocessing the extracted keyword, and a method of enabling a user to use it for future navigation or additional search.

S10, S20, S30, S40, S50, S60: Each module constituting the system.

The present invention has been conceived in that the string constituting the URL is selected from among the names that most reflect the characteristics of the website or from the most relevant words. Looking at the structure of URL, four domains are connected and are as follows.

The top level domain of a URL contains information about the nature of the domain (military, company, education, country, etc.).

-Second level domains contain information of personality (group, company, network, school, etc.).

3rd level domain contains organization name and site keyword

4th level domain contains information about the name of the server

time

URL of the National Assembly: www.assembly.go.kr

3rd level domain: assembly

Second level domain: go

Top-Level Domains:

In this case, the third-level domain 'assembly' is extracted as a keyword, and the second-level domain 'go' represents the category of the website of the government agency, and the top-level domain 'kr' represents the country of Korea. The extracted keyword is assembly and there are 'parliament' as translation words. There are similar words 'parliament' and 'congress' and related words are 'parliamentary record', 'parliamentary schedule', 'parliamentary member', 'general election', 'legislature'. Search results of related sites through search engines, such as 'National Library of Congress', 'History of National Assembly', 'Introduction of the National Assembly's Chairman', and 'National Assembly Budget Monitor' Can be.

Also, for www.yahoo.com, the top-level domain 'com' represents the nature of the domain, and because it's not a country domain, there's no second-level domain, and the third-level domain is' yahoo ', so the keyword is a third-level domain' yahoo 'can be extracted.

In addition, when using the keyword service, a user may input the keyword itself into the address window from the beginning. In this case, the keyword is a keyword input by the user and the keyword of the user is displayed in the keyword display window S220 as it is.

In some cases, it is difficult to think that the keywords are properly extracted from the URL. In other words, when constructing URLs or domain names, the purpose is to keep them as short as possible, or to preempt good words so that the URLs are made of suboptimal words, circumventive words, or extremely unrelated strings. There may be. Two complementary methods can be used for this.

First, for abbreviations or abbreviated words, it is possible to store keywords that can be expected from abbreviations and abbreviated strings separately from the dictionary DB to compensate for the difficulties in searching the dictionary DB when the strings come. Can be used.

Second, a method of extracting a keyword from a name and a comment on a corresponding URL output from a search engine by transferring a URL input or displayed in a web browser address window S210 to a specific search engine as it is. According to this method, keyword extraction accuracy can be improved even for sites that use URLs or domain names with strings irrelevant to the nature of the web site.

In order to implement the above two complementary measures, the definitions of these strings should be prepared in the database so that the system can expand them from the abbreviations or abbreviations to the keywords. You need a program module that sends and retrieves information from that site.

The system proposed by the present invention for the keyword extraction and processing and expansion to the related word and related site list is composed of the following modules.

(i) a program module for accepting a character string input or displayed in an address window, wherein the module inputs a character string or displays a web site URL in a web browser address window (S210);

(ii) a program module for classifying input strings and extracting keywords, wherein the module extracts keywords from the third-level domain and (S20)

(iii) a program module for processing the extracted keywords, wherein the module finds similar words, synonyms, translation words, and related words for the keyword (S30).

(iv) a database for processing keywords and a module for retrieving related words with keywords, the module for retrieving dictionaries, synonyms, synonyms, and related words from its own or external database on a specific server or search engine, and (S40 )

(v) a user interface program module for defining a method of processing and displaying a keyword, wherein the module provides a selection of whether to display only the keyword or how to process the keyword and display the keyword (S50).

(vi) a program module for executing a search or connection for a string, and a module for executing a web browser S230 in a manner desired by a user

It consists of six modules in total. (S60)

In this case, the location of each execution module may vary depending on how the program is implemented. The entire module and the database listed above can be located on the user's terminal, or the whole can be placed on a specific external server or a part of the user can be located. It can also be deployed in the terminal and distributed to some of the external servers.

The operation of each module listed above is the same as the described order, but the `(v) user interface program module defining the manner in which the keyword is processed and displayed '(S50) is a step in which the user uses the system of the present invention. If there is no user's method definition, it is executed by the system predefined method.

In addition, the `(iv) database for processing keywords and program modules for searching related words by keyword '(S40) describes the database and two program modules for searching them together. All of the databases on a particular server are possible. A program module that searches for related words for a keyword is ready to search a search engine or a specific database as soon as the keyword is extracted from the URL, to search for words or related sites related to the extracted keyword and display them in the user's toolbar or address bar. do.

The extracted keyword and related words of the keyword can be displayed in a keyword display window (S220), a toolbar or a pop-up window. Ideally, a keyword display window (S220) is created next to an address window to extract extracted keywords and related words. It is preferable to list them and search can take time, so it is desirable to add relevant words or websites to the display as they are searched.

Program module that accepts the strings entered or displayed in the `(i) address bar above in the same way as the user input, even if the URL is displayed in the address bar of the web browser by a visit to the website, not by the user. It is accepted as a character string by the program described in the item '(S10)', where the extraction and processing of keywords, the searching of related words or related web sites, and the display of processed results are repeated according to the user's navigation.

The program module for executing a search or linking to the '(vi) string' above (S60) reduces the procedure and time for visiting the search engine while the user is navigating, and the user is able to adapt the system and method proposed by the present invention. As a result, the processed result displayed in the keyword display window S220, the toolbar, or the pop-up window can be selected to immediately search or immediately open the web site using the corresponding keyword.

In the present invention, the user inputs a keyword or URL every time in the web browser address window (S210) in order to connect to the website, and also re-enters the URL from the beginning when the connected site is not a desired site or needs to be moved to another related site. It also reduces the inconvenience of having to search related sites from search engines and processes and presents keywords and related keywords from the sites that users have visited once. It can pre-search for highly probable websites and prepare related words in advance on the user's device. This saves time and effort for URL input, repetitive search and navigation.
