Description

A method for providing a list of search results reflecting importance information and its system {A METHOD FOR PROVIDING SEARCH RESULTS LIST BASED ON IMPORTANCE INFORMATION AND A SYSTEM THEREOF}

The present invention relates to a method and a system for providing a search result performed in a search engine, and more particularly, to a search engine reflecting importance information in processing a search result list corresponding to a predetermined keyword input from a user terminal. A method and system for generating a result list are provided.

As will be appreciated by those skilled in the art, the most common search service method performed in the search result providing system is a keyword search method. When a keyword is input from a user, a search result providing system that provides the keyword search service includes a search result including the keyword (for example, a web site including the keyword, an article including the keyword, and the keyword including the keyword). An image having a file name) is provided to the user terminal.

According to such a conventional search result providing method and system thereof, in providing a search result list for a specific keyword input from a user terminal, one or more contents are arranged in the order of registration or accuracy calculated by a predetermined accuracy calculation algorithm. Doing. 1A and 1B show an example of a search result list processed according to this conventional search result providing method.

Referring to FIG. 1A, in a conventional method for providing a search result list, a method of searching for content including a predetermined keyword and then providing one or more searched contents in order of registration time is illustrated.

In addition, FIG. 1B illustrates a method of providing a search result list in a typical manner, in which a content including a predetermined keyword is searched and then one or more searched contents are provided "in order of accuracy." The method for providing a list of search results "in order of accuracy" according to the related art uses the following method. First, it searches for how much the entered keyword query is included in the corresponding content. Through this search, the frequency of occurrence of the keyword in the content, the location of the keyword in the content, the structure of the related content document, etc. are quantified. In addition, the content is digitized in consideration of the length, link depth, link degree, piclink degree, popularity, configuration information of the content itself (whether it is adult or spam content), and the like. Also, depending on the implementation, the recommendation data input of the corresponding content provider may be reflected in the accuracy calculation. For example, in the case of editor-recommended content of a search engine operator, the editor may adjust the accuracy value of its service item or recommendation content when the content is input, thereby increasing the exposure frequency of the corresponding content. The above information is analyzed separately and digitized according to a predetermined algorithm, and the digitized data is normalized and defined as a value between 0 and 1 (or 0% to 100%). Can be used as data

The above-described conventional search result providing method can be largely arranged in two ways.

(1) The content is searched using the keyword query, the accuracy is calculated, and the one or more searched contents are sorted based on the accuracy value result.

(2) Search for content using the keyword query and calculate the accuracy, and then sort one or more content having an accuracy value result based on the date and time information (or input time information of the content) registered in the content registration database. .

According to such a conventional method of providing a search result and a system thereof, in the case of content in which the concept of time is important, that is, news article content or knowledge search content with timeliness, a simple accuracy-based sorting or a registration date-based sorting is accurate. The problem is that the search results are not easy to find. For example, when a user searches for the aforementioned timely content using the keyword 'patent', according to the conventional method for providing search results, the search result list may be viewed only in the order of accuracy or the date of registration. You can browse the list of search results with the highest accuracy but not sorted in the order of registration date for the keyword, or you can view the list of search results with the registration date for the keyword 'patent' but not sorted in the order of accuracy. It is inconvenient to search several pages of the search result list to find the desired content.

As another example, if a user wants to use web content (such as webpage content, news article content, or knowledge search content) about what are "hot movies" these days, according to the conventional method of providing a list of search results, Provide users with a list of search results sorted by accuracy that does not reflect the concept of time for popular movies, or a list of search results sorted by registration date and time that do not reflect the concept of accuracy for popular movies. Since there is no choice, there is a problem in that it is difficult for a user to provide a desired search result. This problem has caused a lot of inconvenience and user complaints to users who want a faster and more accurate list of search results.

In addition, in the case of a mobile search service using a personal mobile terminal, which has been recently activated, a user may need to read a search result list in order to find a desired content, which may increase unnecessary communication costs. This happens.

Due to the above-described problems, in the search result list providing method currently commonly provided, a more advanced search result list providing method capable of searching for information desired by the user from the initial search result list has been desired.

The present invention has been made to solve the problems of the prior art as described above, and provides a search result providing method and system that can provide a search result list based on the accuracy and importance information reflecting the registration time information of the content It aims to provide.

The registration date and time information means time information input / input of predetermined web page data, news article data, or knowledge search data from a predetermined content provider or the like according to the present invention, or the data is registered in a database. May mean visual information.

In addition, the search result providing system according to the present invention maintains a timer function for holding time information and a time function table for storing a predetermined time function whose variable is time difference information (step 302). The disparity information recorded in the time function table means a difference between registration date and time information of the content and the time information held in the timer means. For example, the time information may be current time information, and may receive any time information desired by the system operator or the search engine user, and record the time information.

4 is a diagram showing an example of a time function table for recording a time function value corresponding to time difference information, which is used in the first embodiment of the present invention. Referring to FIG. 4, a time function table according to an embodiment of the present invention records time function values corresponding to predetermined time difference information. For example, when the time difference information is 3 hours, a time function value corresponding thereto may be 0.98. Such a time function value may have a value that decreases as the time difference information increases, which means that the time function value of the corresponding content decreases as the date and time information on which the corresponding content is registered moves away from the current time information. According to an embodiment of the present invention, the time function table may be prepared in the form of a time function value corresponding to the time difference information, or a time function corresponding to the time difference information by recording the time function itself using the time difference information as a variable. Can be written to compute a value.

One example of a formal model of a time function that can be used to create or recorded in the time function table shown in FIG. 4 is shown in FIGS. 5A-5E.

5A to 5E illustrate examples of modeled time functions that may be used in the method for providing a search result list according to the first embodiment of the present invention.

5A illustrates an example of a modeled time function that may be used to calculate the time function value shown in FIG. 4. The time function illustrated in FIG. 5A is an example of a model in which a predetermined intercept is taken when the parallax information t is 0 as a linear function and the time function value gradually decreases as the parallax information increases.

5B illustrates an example of a modeled time function that may be used to calculate the time function value shown in FIG. 4. The time function shown in FIG. 5B is a spherical function that takes a predetermined intercept when the time difference information t is 0 and has a value of B for the time difference information, and when the time difference information becomes T or more, One example of a model with a constant value near zero or zero.

5C illustrates an example of a modeled time function that may be used to calculate the time function value shown in FIG. 4. The time function shown in FIG. 5C is an example of a model that takes a predetermined intercept when the parallax information t is 0 as a quadratic function and gradually decreases the time function value as the parallax information increases.

5D shows an example of a modeled time function that can be used to calculate the time function value shown in FIG. 4. The time function illustrated in FIG. 5D is an exponential function, which is an example of a model in which a predetermined intercept is taken when the parallax information t is 0 and the time function value gradually decreases as the parallax information increases.

5E illustrates an example of a modeled time function that may be used to calculate the time function value shown in FIG. 4. The time function illustrated in FIG. 5E is a Gaussian function, which is an example of a model in which a predetermined intercept is taken when the parallax information t is 0 and the time function value gradually decreases as the parallax information increases.

As described above, the modeled time function illustrated in FIGS. 5A to 5E basically decreases as the time difference increases as the time difference information increases. Various functions may be used depending on the implementation. In addition, the examples of the time function illustrated in FIGS. 5A to 5E are illustrated as the time function values converge to zero as the time difference information increases, but this example is exemplary and may be flexibly to have a non-zero value according to the implementation. It will be obvious that it can be modified.

Returning to FIG. 3A, a predetermined keyword desired to be searched by the corresponding user is input from the user terminal (step 303). The search result list providing system according to the present invention receives the corresponding keyword and searches for one or more contents including the keyword by referring to the content storage database (step 304). The accuracy of the corresponding content for the keyword is calculated according to the selected accuracy calculation algorithm for the one or more contents including the corresponding keyword (step 305). As described above, the accuracy calculation algorithm performed in step 305 searches for how much of the input keyword query is included in the corresponding content, and through this search, the frequency of occurrence of the keyword in the corresponding content, and the keyword within the corresponding content. The position, the structure of the related content document, etc. may be digitized, and the numerical data may be normalized to define a value between 0 and 1 (or 0% to 100%). Such an accuracy calculation algorithm may use a known algorithm, and a modified accuracy calculation algorithm may be used according to the object of the present invention.

Next, the registration date and time information of the retrieved content is retrieved by referring to the content information database (step 306). The time difference information is calculated using the registered date and time information retrieved in step 306 and the time information received from the timer means (step 307). In step 307, the time difference information is calculated by subtracting the registration date and time information from the time information to determine how much time has passed from the registration date and time information.

Referring to FIG. 3B, a time function value corresponding to the calculated time difference information is calculated with reference to the time function table according to the time difference information calculated in step 307 (step 308). As described above, the time function table may record a time function value corresponding to a predetermined time difference, calculated using various time functions capable of modeling a time function concept according to FIGS. 5A to 5E. It may be implemented to record the time function itself and calculate a time function value corresponding to the calculated parallax information. In step 308, specific time difference information (e.g., 3 Hours 37 Minutes, etc.) may not be recorded in the time function table. In this case, an approximation of the time difference information field of the corresponding time function table (e.g., 3 Hours and 4 Hours) may be obtained. It can be operated to determine the time function value by reading and approximating.

The accuracy calculated in step 305 and the time function value calculated in step 308 are calculated to calculate importance information according to the present invention (step 309). The operation performed in step 309 may be a multiplication process, and may be implemented to determine whether to prioritize the accuracy of the corresponding content or the parallax information by multiplying the accuracy or time function value by a predetermined weight depending on the implementation. have.

One or more pieces of content are sorted based on the importance information calculated in step 309 (step 310), and the search result list information is processed according to the sorted content (step 311). Step 311 may be performed according to a search result list format used in each search engine, and how many search results are included in one web page and how detailed the search results are described may vary depending on the implementation. There may be variations or modifications. In the processing of the search result list information, if the importance information calculated in step 309 is less than or equal to a predetermined threshold, the corresponding content may be excluded from the search result list information.

The time difference information is calculated using the registered date and time information retrieved in step 606 and the time information received from the timer means (step 607). In step 607, the time difference information is calculated by subtracting the registration date and time information from the time information to determine how much time has passed from the registration date and time information.

A time adverb keyword stored in the temporal adverb keyword database is extracted from the retrieved one or more contents (step 608). With respect to the temporal adverb keyword extracted from the content, a weight corresponding to the temporal adverb keyword and the parallax information calculated in step 607 is read with reference to the temporal adverb keyword database (step 609). If the number or types of temporal adverb keywords included in the corresponding content is one or more in operation 609, the read weight may be calculated according to a predetermined algorithm to calculate the final weight for the corresponding content. It can be appropriately devised and used by the operator of the search result list providing system according to the present invention.

Referring to FIG. 6B, the importance information according to the present invention is calculated by calculating the accuracy calculated in step 605 and the weight read in step 609 (step 610). The operation performed in step 610 may be a multiplication process, and depending on the implementation, it may be determined whether to prioritize the accuracy of the corresponding content or the weight associated with the temporal adverb keyword by multiplying the accuracy or weight by a predetermined second weight. Can be implemented.

One or more pieces of content are sorted based on the importance information calculated in step 610 (step 611), and the search result list information is processed according to the sorted content (step 612).
