The present invention relates to a search system and method, and more particularly, to a visited website search system and a visited website search method for searching a website visited by a user.

As the Internet develops, web search services are becoming more common in order to effectively manage vast amounts of data on the Internet. The web search service automatically tracks the hypertext structure of the web using a web robot to recursively search the referenced documents and index the searched documents. A user can access a web search service site through the Internet and enter a keyword to search for information such as a web document he or she wants in an indexed database.

The storage space of personal computers such as desktops and notebooks is greatly increased, and files containing a large number of documents, pictures, mails, instant messages, videos, or music are stored on desktops or notebooks. Stored in, the need for local computer searches targeting data within desktops or laptops, as well as web searches, has emerged.

For example, if a user of a desktop computer writes a review about a movie "Ireland" using a word processor, and a few years later, to find an "Ireland" review somewhere stored on his computer, the directory and file name where the file is stored must be You must remember. However, it is virtually impossible to remember the directory and file name for all documents and the like.

Even if you don't remember the directory where you saved the file, if you know the file name or the string included in the file content, you can find the file you want by using the file search function provided by the operating system (OS). However, since the file search function provided by the operating system searches for information in the user's computer in real time, it takes a long time, and the inconvenience has been increased as the capacity of the storage space in the computer such as a hard disk increases.

To alleviate this inconvenience, a "desktop search" service has been introduced. When a user enters a keyword through a deskbar, toolbar, or web browser window, the "desktop search" service searches for information in the user's computer related to the entered keyword using a pre-indexed database. Desktop Search makes it easy to find what you're looking for by searching for information on your computer, saving you the hassle of manually organizing your files, emails, and favorites.

However, the existing "desktop search" service modifies network system files provided by the operating system (OS), such as the socket dynamic link library (DLL), intercepts desktop search commands in a web browser, and generates desktop search results. Then, it was delivered to the web browser through the modified network system file.

Therefore, the existing "desktop search" service is modified by certain operating systems (Operating System (OS)) or other applications, such as the "winsock.dll" file, or other DLL (associated with the specific file, such as "winsock.dll" file ( Dynamic Link Library) file is modified, an error such as screen breakage occurs when accessing a specific website, and the operation is unstable. In general, updates to the operating system or application programs are frequently performed, and the existing "desktop search" may occur whenever the update is performed, which may change the socket DLL and the system DLLs that depend on or depend on it. Services were always at risk of errors due to updates of the operating system or other applications.

Furthermore, as a kind of desktop search service, a visiting website search service targeting a website visited by a user has also been introduced. In other words, when a user enters a keyword, the search results provide the website related to the entered keyword among the websites visited by the user so that the user can enter the relevant keyword even if the user does not remember the exact address of the website visited by the user. You can enter information about the website you've visited or return to it.

Various attempts have been made to effectively implement such a visited website search system. However, in the past, in order to implement such a service, the service is unstable using a method such as changing the registry inside the operating system, and the system is complicated to implement. Costly, and system maintenance was difficult.

Accordingly, there is a need for a visited website search system and method capable of stably operating using the HTTP protocol and providing a keyword search service targeting a user's web history, similarly to a conventional website search. It emerges desperately.

The present invention has been made to solve the problems of the prior art as described above, visited website search system and visited website search system that operates stably according to the HTTP protocol as well as a normal website search by operating on a web server It is an object to provide a method.

Another object of the present invention is to provide a visited website search system and a visited website search method that are easily compatible with the existing web search system by using the same HTTP protocol and interface as the existing web search service.

In addition, an object of the present invention is to provide a visited website search system and a visited website search method that can collect a website visit history of a user simply and efficiently by monitoring a web browser using a browser helper object.

In addition, an object of the present invention is to provide a visited website search system and a visited website search method that can be easily implemented by indexing a website visit history in a polling manner and operate efficiently while reducing the load on the system. do.

In addition, the present invention accesses the website history database at regular intervals, and operates by using a separate timer included in the CPU chipset of the local computer, such as visiting website search system and visiting website search that can reduce the burden on the CPU. It is an object to provide a method.

The present invention also provides a visited website search system and a visited web that can reduce the collection and indexing of unnecessary visited website information by not updating the website information visited by the user when the user revisits a specific site within a certain period of time. Its purpose is to provide a site search method.

In addition, the present invention is provided with a separate resource component that provides the resources necessary to create a screen provided to the user through a web browser, visited website search system and visit that can effectively create a screen even if the language or font is changed It aims to provide a website search method.

In order to achieve the above object and solve the problems of the prior art, a visiting website search system for searching a website visited by a user according to an embodiment of the present invention is installed on a local computer, a web browser according to the HTTP protocol A mini web server that receives a search command for a website visited by a user from the web site, and provides a web browser search result to the web browser; a website corresponding to a query included in the search command among the websites visited by the user; It characterized in that it comprises a search unit for generating a search result by searching for and a web document generation unit for converting the search results into a web document format to generate a search result of the web document format.

In this case, the visited website search system may be implemented in a browser helper object (BHO) format, and may further include a website visit monitor configured to monitor the visit of the website of the user and store information about the website visited by the user. have. At this time, the browser helper object (BHO) is not limited to operating in conjunction with Microsoft Internet Explorer. That is, a program module for operating in addition to the web browser and extending the function of the web browser may be included in the browser helper object of the present invention regardless of its name.

In addition, the visited website search method for searching a website visited by the user according to another embodiment of the present invention, the mini-web server installed on the local computer, a search command for the website visited by the user from a web browser according to the HTTP protocol Receiving a search result, searching for a website corresponding to a query word included in the search command among the websites visited by the user, and generating a search result; converting the search result into a web document format to search the web document format; Generating a result and providing the web browser with search results in the form of a web document.

At this time, the local computer is a microprocessor and storage space such as a desktop computer, a notebook computer, a laptop computer, a personal digital assistant, a mobile phone and an MP3 player. It includes all the devices provided with. At this time, the storage space may be a hard disk, RAM or ROM, the storage space may be a local computer internal or external.

In addition, the local computer may be a concept including a plurality of computers connected through a local-area network (LAN).

At this time, the communication between the web browser and the mini web server may be performed using a loop back interface, thereby disallowing access to the mini web server from the outside.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a visiting website search system according to an embodiment of the present invention.

Referring to FIG. 1, a visited website search system according to an embodiment of the present invention includes a web browser 110, a website visit monitoring unit 120, a mini web server 130, an index unit 140, and a search unit. 151, web document generation unit 153, resource component 155, index database 160, and website history database 170.

The web browser 110 is software that helps the user's computer to view various information obtained from a web server by accessing the Internet. For example, the web browser 110 may be Microsoft's Internet Explorer, Netscape's Communicator, or Mozilla's Firefox. The web browser 110 includes all program modules that serve to receive a search word from a user and deliver the search word to the mini web server through the HTTP protocol, in addition to the normal web browser.

The web browser 110 provides an input interface for receiving a search command from the user, and displays the search result in the form of a web document to the user.

In this case, the input interface may correspond to an input interface for a general web search. That is, the web browser 110 may allow a user to input a keyword in the same format as an input interface for a normal web search, and to set only a search target as a visited website search.

In this case, when the user requests a search for data in the local computer, the web browser 110 may set a destination address of the search command as a local computer or a loopback address where the web browser 110 is installed.

The search result of the web document type may be a HyperText Markup Language (HTML) document. In this case, the web document type search result may include resources such as an image or a phrase necessary for the search result of the visited website. At this time, the web browser 110 reads the search result of the HTML document format and displays it on the screen.

The website visit monitoring unit 120 is implemented in a browser helper object (BHO) format, and monitors the user's visit to the website and stores information about the website visited by the user. At this time, the browser helper object is a kind of plug-in module used to extend a function of a web browser such as Internet Explorer (IE), and is executed by an explorer or a web browser in the form of a DLL (Dynamic Link Library). do. The browser helper object can be automatically executed by the explorer at the start of an operating system such as Windows, and can be useful for monitoring all web accesses of the user while the local computer is running.

At this time, the website visit monitoring unit 120 expands the function of the web browser 110 to monitor the user's website navigation through the web browser 110 and visits the user's website through the web browser 110. The history may be collected and stored in the website history database 170. In this case, the website visit history may be a collection of data included in the website for each website visited by the user. For example, the website visit history may include one or more of a URL, a site title, an HTML source in the extracted text format, and a thumbnail image of the browser snapshot of each of the websites visited by the user.

In this case, the website visit monitoring unit 120 may parse the HTML source of the visited website in the form of text collection by collecting the website visit history.

Site1 URL1 Title 1 HTML1 Thumbnail 1 Site2 URL2 Title 2 HTML2 Thumbnail 2 Site3 URL3 Title 3 HTML3 Thumbnail 3 Site4 URL4 Title 4 HTML4 Thumbnail 4

Table 1 is an example of data stored in the website history database 170.

As shown in Table 1, each time a user visits a new website, the URL of the visited site, the site title, an HTML source in extracted text format, and a thumbnail image of the browser snapshot are stored in each field in the history database 170. Can be.

The website visit monitoring unit 120 may register sites that will not record the website visit history on the blacklist, and may not record the website visit history when the user visits a site registered on the blacklist. As such, by blacklisting unnecessary sites, the user can exclude visit histories for unwanted sites from the visiting website search results.

In addition, the website visit monitoring unit 120 may not record the website visit history when the user revisits the same site within a predetermined time.

For example, if a user visits the same site within 7 days, the website visit history may not be recorded. At this time, when the user accesses the site A and records the website visit history, and if the user visits the site A again after 5 days, the website visit history is not updated again and recorded. If the user accesses the site A and records the website visit history, and if the user visits the site A again nine days later, the website visit history is updated again and recorded.

Typically, a user frequently visits some frequently used websites, in which case it is very inefficient to save the website visit history every time the website is visited. Therefore, the system resource used to unnecessarily update the website visit history can be saved by setting not to record the website visit history for the revisit within a predetermined period in consideration of the update period of the website.

2 is a flowchart illustrating an operation of the website visit monitoring unit 120 illustrated in FIG. 1.

1 and 2, the website visit monitoring unit 120 monitors the operation of the web browser 110 while the web browser 110 is running (S210).

At this time, the website visit monitoring unit 120 may monitor the address bar of the web browser 110 and the page being loaded and the user's operation of the web browser 110.

The website visit monitoring unit 120 monitors the web browser 110 and determines whether the user visits the web page and finishes searching the corresponding web page (S220).

If the user did not complete the search for the web page, the website visit monitoring unit 120 returns to step S210 to continue monitoring the web browser.

When the user completes the search for the web page, the website visit monitoring unit 120 determines whether the visited web page is included in the black list (S230).

If the visited web page is included in the blacklist, the website visit monitoring unit 120 does not store the visit record for the web page, and thus returns to step S210 to continue monitoring the web browser again.

If the visited web page is not included in the blacklist, the website visit monitoring unit 120 determines whether there is a previously visited record on the website (S240).

At this time, the determination of whether there is a previously visited record may be performed by referring to the data indexed in the index database 160.

When the first visit to the website, the website visit monitoring unit 120 stores the visit record (S260).

At this time, the visit record may be stored in the form shown in Table 1 above.

If there is a record of the previous visit to the website, the website visit monitoring unit 120 determines whether the visit is within a predetermined period (S250).

In the case of a return visit within a predetermined period, the website visit monitoring unit 120 returns to step S210 to monitor the web browser without storing the visit record again.

In the case of a return visit after a predetermined period has elapsed, the website visit monitoring unit 120 stores a visit record (S260).

FIG. 3 is a flowchart illustrating an example of storing the visit record (S260) shown in FIG. 2.

Referring to FIG. 3, the storing of the visit history shown in FIG. 2 determines whether there is an error in the visited web page (S310).

If there is an error in the visited web page, the visit history storing step cannot normally save the visit history and thus monitors the web browser again.

When there is no error in the visited web page, the visit history storing step determines whether website information extraction is successful (S320).

At this time, the extraction of website information means reading the URL, site title, HTML source, etc. of the visited website, and if necessary, parsing or the like to extract information of a desired form.

When the extraction of the website information fails, the visit history storing step cannot normally save the visit history, thereby monitoring the web browser again.

If the website information extraction is successful, the visit history storing step determines whether the snapshot resizing is successful (S330).

At this time, snapshot resizing means creating a thumbnail image of the browser snapshot.

If the snapshot resizing fails, the history recording step will not be able to save the history normally, so monitor the web browser again.

When the snapshot resizing is successful, the visit history storing step stores the website visit history (S340).

Referring back to FIG. 1, the mini web server 130 receives a user's search command from the web browser 110 by communicating with the web browser 110 according to the HTTP protocol and receives the search result of the web document format in a web browser ( 110). At this time, the mini web server 130 is a kind of web server installed in the local computer.

At this time, the mini web server 130 examines the source address of the received search command and provides a service only when the source address is the same address or loop back address as the local computer on which the mini web server 130 is installed. Can be set.

The mini web server 130 may be accessed only from a local computer on which the mini web server 130 is installed through a loop back interface, and may not be accessible from an external computer through the Internet.

The index unit 140 builds an index database 160 by indexing data in the website history database 170.

At this time, the index unit 140 may operate in a polling manner to access the website history database 170 at a predetermined time interval and index the website visit history. By operating in a polling manner, the website history database 170 is accessed to index the website visit history, so that the visit is simpler and more effective than indexing the website visit history according to events that occur every time a user visits the website. Implement a website search system.

For example, the index unit 140 may access the website history database 170 to index the website visit history at intervals of about 1 to 2 seconds, and in this case, whenever the user visits a specific website. It can reduce the system load compared to indexing website visit history.

According to an embodiment, the index unit 140 generates an event at each predetermined time interval by using a separate timer that is independent of the central processing unit (CPU) of the local computer to visit the website visit history. Can be indexed. As such, by using a separate timer from the CPU, the load on the CPU can be reduced.

In addition, the index unit 140 may delete the website visit history which is indexed when the website visit history is indexed from the web history database.

4 is a block diagram illustrating an example of the index unit 140 illustrated in FIG. 1.

1 and 4, the indexer 140 includes a timer event detector 410, an indexer 420, and a controller 430.

The timer event detector 410 detects an event such as an overflow occurring in a timer included in the CPU chipset. For example, the timer may be set to cause an overflow to occur every 1 second, and the timer event detector may detect the overflow every second.

The indexer 420 accesses the website history database 170 and extracts the index word by indexing the website visit history whenever the timer event detector 410 detects a predetermined timer event, and builds the index database 160. do. At this time, the indexer 420 may delete the indexed website visit history from the website history database 170.

The controller 430 controls the indexer 420 according to the detection result of the timer event detector 410.

Referring back to FIG. 1, the search unit 151 receives the search command from the mini web server 130 and searches the index database 160 using the query word included in the search command to generate a search result. In FIG. 1, the search unit 151 receives a search command from the mini web server 130, but the search unit 151 may receive a search command from the web document generation unit 153. In this case, the web document generation unit 153 may receive a search command from the mini web server 130.

The web document generator 153 converts the search result into a web document format to generate a search result in the web document format.

In this case, the web document may be an HTML document. That is, the web document generation unit 153 may generate the search result in the HTML format by converting the search result generated by the search unit 151 into the HTML format. In addition, the web document generation unit 153 may generate a web document such as an HTML document by adding resources such as an image or a phrase necessary for a search result.

According to an embodiment, the web document generation unit 153 may receive a resource from the resource component 155 for converting a search result into a web document format.

The resource component 155 may provide resources necessary for generating a web document type search result or a web document other than the search result. In this case, the web document other than the search result may be a web document indicating the index status of the local computer, a guide web document relating to a visited website search, or the like.

The resource component 155 may store various resources required to generate a web document, such as a string for each language or font.

As described above, the mini-web server 130 is provided so that the web browser 110 and the mini web server 130 communicate with each other according to the HTTP protocol. You can build a system. Furthermore, since the visited website search system according to the present invention operates on a web server basis, even when a user uses two or more computers, the search results collected from the mini web server provided in each computer can be easily obtained according to the HTTP protocol. Can be aggregated to effectively perform a visited website search.

Until now, the website visit monitoring unit 120 constructs the website history database 170, and the index unit 140 indexes the information about the website visited by the user with respect to the constructed website history database 170. Although described with reference to an embodiment, the index unit 140 may directly index information about a website visited by the user from the website visit monitoring unit 120 without passing through the website history database 170. Information about a website visited by a user may be indexed in a database inside / outside the local computer other than the website history database 170.

FIG. 5 is a view for explaining an indexing operation of the visiting website search system shown in FIG. 1.

Referring to FIG. 5, a user of a visiting website searching system visits desired websites through a web browser (510).

The website visit monitoring unit operating in conjunction with the web browser monitors the user's website visit through the browser (520).

The website visit monitoring unit stores the website visit history of the user in the website history database (530).

At this time, the website visit monitoring unit may not store visit records for websites registered in the blacklist. In addition, the website visit monitoring unit may not store the visit record for the website visited again within a predetermined time.

The visited website search system uses a timer (apart from the CPU) included in the CPU chipset of the local computer to generate a predetermined event every predetermined time (540).

For example, the timer may be set to generate an event such as an overflow every about 1 to 2 seconds.

In step 550, the website history database is accessed to index the website visit history and the index database is established at the timer at the predetermined time when the predetermined event occurs.

6 is a view for explaining a search operation of the visited website search system shown in FIG.

Referring to FIG. 6, the visited website search system transmits / receives a user's search command and a search result in a web document format between a web browser and a mini web server using the HTTP protocol (610).

By using the mini web server, communication between the web browser and the mini web server can be performed like a conventional web search, so that it is easy to be compatible with the conventional web search system and a stable visiting website search system can be constructed.

When the search command of the user is transmitted through the web browser and the mini web server, the visit website search system searches the index database using the query word included in the search command and generates a search result of the visit website (620).

When the visited website search result is generated, the visited website search system generates a web document such as an HTML document to be provided to the user by adding necessary resources such as an image or text (630).

The controller illustrated in FIG. 6 is divided for convenience of description of the operation of the visited website search system and does not necessarily correspond to the components of the visited website search system illustrated in FIG. 1 or 4.
