EMBODIMENT OF THE INVENTION Hereinafter, 1st Embodiment of this invention is described in detail with reference to drawings.

1 is a schematic diagram showing the configuration of a user's preference prediction system for a search result document according to a first embodiment of the present invention.

Referring to this, the user's preference prediction system for the search result document according to the first embodiment of the present invention classifies the search result information into a video, text, audio, and picture file, and checks the average of the search results in consideration of the capacity of each information. After setting and saving the time data, the user's preference is improved by receiving confirmation time data about the search result from the user's web browser and automatically assigning a preference score for the search result information based on the check time. It is a system that can accurately predict.

That is, the user's preference prediction system for the search result document according to the first embodiment of the present invention is a system for automatically predicting the user's preference for the search result information when the user searches for information in the search portal. Search result preference linked with portal server In the state of registering the file type and size of each search result information, language type constituting the file, and average time information for viewing the file in advance, the search is performed. By checking the reading time of the user viewing the result, that is, the opening time of the web browser in which the search result information is output, the user's preference can be automatically evaluated.

More specifically, the user's preference prediction system for the search result document according to the first embodiment of the present invention, in consideration of the type and size of the file for the search result information, the average time required to view the search result information Set the information, check the viewing time of the search result information output through the user's web browser, accumulate the reading time of each user, and divide the number of the corresponding user by the number of the corresponding user as a numerical value It can be converted.

For example, assuming that the file for the search result information is text, and that the language of the text file is Korean and that the average reading time considering the size is 5 minutes, the preference evaluation score is set in 1 minute increments based on 5 minutes. Can be. That is, a score of 0 can be given if the reading time is taken from 4 minutes 30 seconds to 5 minutes 30 seconds, and -1 if the reading time is taken from 3 minutes 30 seconds to 4 minutes 30 seconds. Point, +5 points can be given when reading time from 5 minutes 30 seconds to 6 minutes 30 seconds is required.

If one user scores 0 points in consideration of the time it takes for a user to view the search result information, and the latter scores 1 point in view of the time spent in reading the search result information of another user, the latter user When the search result information signal is applied from the user's terminal, the preference score is accumulated and 1 point is accumulated, and the cumulative preference score is divided by 2, which is the number of users who read the search result information, and the preference score is 0.5 point. Can be evaluated.

As can be seen from the preference score evaluation, since the average preference is 0, it can be seen that the cumulative preference score above 0 is a result higher than the average preference, and for the cumulative preference score below 0, the average preference is 0. It can be seen that the search results are lower.

In this case, in the conventional search portal, a user who posted a specific question was assigned a score for the corresponding answer content by manually inputting a score for the answer content only for the answer to the question, but actually answered The system for assigning the evaluation score was not applied to the search results other than the method, and since the evaluation score was manually assigned to the contents of the user who asked the question, it is annoying and therefore it is not annoying so that the accurate rating is not given. There was a problem that the investigation did not occur, even if the user who did not ask the question about the same question and answer content, only the answer content is viewed and the evaluation score is not given.

In order to solve this problem, the user's preference prediction system for the search result document according to the first embodiment of the present invention can be automatically assessed preference so that the cumulative preference evaluation of the search result can be objectively performed. It is designed to be a system.

The user's preference prediction system for the search result document according to the first embodiment of the present invention automatically performs a cumulative preference evaluation of the search result, so that the search result preference prediction server receives a read request signal for the search result of the user. Received from the terminal, transmits the hyperlinked search result information to the web browser of the user terminal to output the screen in the form of a pop-up window, and when the reading end signal occurs in the hyperlinked search result information data, the search end signal is sent to the search result Embed control data to be sent to the preference prediction server.

In this case, the screen output via the pop-up window is described in the present invention for screen output of the search result information through the user's preference prediction system for the search result document according to the first embodiment of the present invention. The information is not limited to the pop-up window, but can also be output from the main page of the search portal provided with the search box, similar to the output of general search result information.

In addition, the user's preference prediction system for the search result document according to the first embodiment of the present invention does not include control data in the search result information data, and uses a separate control module linked to a web browser in the corresponding user terminal based on a window. And the browsing start state and the browsing end state of the search result information output through the web browser of the user terminal can be transmitted to a remote server.

That is, the user's preference prediction system for the search result document according to the first embodiment of the present invention recognizes the viewing time of the search result information output to the web browser of the user terminal to the remote server, thereby Prediction can be predicted.

Here, the window-based on which the control module is mounted means that the control module itself is an application program, which is window-based for controlling a web browser, or an external program such as a messenger or a toolbar.

To this end, the user's preference prediction system for the search result document according to the first embodiment of the present invention uploads and hyperlinks one or more screen outputable files of video information, image information, voice information, text information, and flash. In this state, the user terminals A1 to An are connected, receive a view request signal for the corresponding search result information, and transmit the corresponding search result information to the corresponding user terminals A1 to An. A search portal server (SPS) is provided which mounts and transmits control data for returning the time data at the time of generation of the reading end signal of the data to the search portal server (SPS).

The viewing time can be calculated and converted into a preference evaluation score.

Therefore, in the state, when the user terminals A1 to An access the search portal server SPS, input a specific word into a search box (not shown), and request a search, the search portal server (SPS) transmits various search information constructed in the search database to the user terminals A1 to An.

Then, the user terminals A1 to An generate a signal for selecting any one of the various search result information transmitted from the search portal server SPS and transmit the signal to the search portal server SPS. . At this time, the search result information selection signal transmits the hyperlink URL information (for example) connected to each search result information to the search portal server SPS by selection of the user terminals A1 to An.

Accordingly, the search portal server (SPS) transmits the URL of the search result information, the Mac address value of the user terminal, and the viewing start time information of the search result information to the search result preference prediction server (SRES). do.

Here, the Mac address value is a means for the server to determine which user the user is, and is not limited to the Mac address value, but other means for specifying the user, that is, IP addresses can also be applied.

The search result preference prediction server SRES may determine whether the user terminals A1 to An request web data about search result information of which URL, and the search result preference prediction server SRES may search for the corresponding search. The URL value of the result data is registered and the time at which the search result data is transmitted to the user terminals A1 to An is stored.

In addition, in the search result data packet transmitted by the search portal server SPS, as shown in FIG. 3A, an end signal transmitted from a web browser of the user terminals A1 to An and the end signal generation time information thereof are displayed. Control data for automatic transmission to the search portal server (SPS) is embedded. The data packet 2 further includes a header (H: 4) indicating the start of general data and a tail (T: 12) indicating the end of the data, and includes first content for storing search result information. (C1; 6), a second content (C2: 8) storing the browsing start time information of the search result information and a third content (D: 10) storing the control data are embedded.

Therefore, when the user generates an operation signal for terminating the viewing of the search result information, the control data mounted in the packet of the search result information is transmitted to the search result information transmitted to the user terminals A1 to An. URL information and end time information for the result information, and the Mac address of the user terminals A1 to An are transmitted.

That is, as shown in FIG. 3B, the data packet 14 transmitted from the user terminals A1 to An includes a header H 4 representing the start of general data and a tail indicating the end of the data. (T: 12), the first content (C1; 18) is configured to store the URL value of the search result information, the second content (C2 :) to store the browse start time information of the search result information; 20), a third content (C3: 22) for storing the browsing end time information of the search result information, and a terminal information storage unit for storing Mac address information of the user terminals A1 to An ( Mac 24 is configured.

Then, the search portal server SPS transmits the URL value of the corresponding search result information and the information of the user's Mac address to the search result preference prediction server SRES, and the search result preference prediction server SRES. ) Calculates the viewing start time and the end time of the search result information of the corresponding user, so that the user can know the total reading time of the search result information of the user, and the reading time data is displayed in the size and language of the search result information. The user's reading time is evaluated based on the average reading time registered by stars and file types (video, image, text, etc.).

That is, assuming that the average reading time required to view the corresponding search result information is 5 minutes, a negative rating score can be obtained when the average reading time is less than that, and a positive rating score is obtained when the average reading time is less than that. Can be.

Accordingly, the calculation of the preference evaluation score is accumulated in each search of each user in the search portal server (SPS), so that the preference evaluation score for each search result information is automatically updated in real time.

Through such a system, users who browse the relevant search result information do not have to separately evaluate preferences, and automatically perform all search result information when a tool for rating evaluation is not mounted on the web. In this way, preference evaluation can be performed, which is very convenient. In addition, in the case of a user for viewing specific search result information, the search result information can be viewed in consideration of the preference evaluation score, and thus a very effective search system can be constructed.
