Hereinafter, a patent map providing system and a method of identifying a correlation between data according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a network diagram showing the configuration of a patent map providing system capable of determining the degree of correlation between data according to an embodiment of the present invention, and a patent map capable of determining the degree of correlation between data according to an embodiment of the present invention. The providing system includes a database unit 100, an intellectual property information providing server 200, and a plurality of client terminals 300. Here, intellectual property or intellectual property means patent and utility model rights.

At this time, the database unit 100 is a member DB (Database) 110 for storing the member information of a plurality of clients, prior art DB 120 for storing a large amount of prior art information of intellectual property, and stores the search result information It consists of a search result DB (130) and a backup DB (140) for storing backup information for each intellectual property right.

In addition, the intellectual property information providing server 200 manages the registered clients, and if the client inputs a search expression or a related search value for searching the intellectual property information through the client terminal 300, the corresponding intellectual The list of property rights and various kinds of information are read from the prior art DB 120 of the database unit 100 and displayed through the client terminal 300. Meanwhile, when the client selects the map creation menu A of the main screen shown in FIG. 3, the intellectual property information providing server 200 distributes the main word selected and input by the user on the secondary plane, and then each main word. By determining and positioning the coordinates of all intellectual property data according to the degree of correlation between the index and the index word of each intellectual property right, the client creates a patent map that makes it possible to grasp the degree of correlation between the subject words of the searched intellectual property list at a glance. To serve.

On the other hand, the plurality of client terminals 300 is a member of the intellectual property information providing server 200 through the Internet (Internet) to install a client tool (Client Tool), the intellectual property information providing server 200 Through the Internet connection with, it receives a variety of information of the intellectual property rights and patent map information of the intellectual property rights to be displayed to each client.

Next, a method of providing a patent map that can determine the degree of correlation between data according to an embodiment of the present invention using the system having the above configuration will be described with reference to the accompanying drawings.

First, when a user selects a log-in through the client terminal 300, the intellectual property information providing server 200 processes an authentication process based on the member information of the member DB 110 (S1). ).

Thereafter, the intellectual property information providing server 200 determines whether the user inputs a search expression for searching intellectual property information or a related search value on the search main screen of the client terminal 300 shown in FIG. 3. Determine (S2).

In this case, when the user inputs a search expression for searching intellectual property information or a related search value (YES) in the second step (S2), the intellectual property information providing server 200 lists the corresponding intellectual property rights. And various kinds of information are read from the prior art DB 120. In addition, the intellectual property information providing server 200 displays the list of the preceding intellectual property rights and various information to the corresponding client through the main screen of the client terminal 300 as shown in FIG. 3 (S3).

On the other hand, the intellectual property information providing server 200 determines whether or not the user selected the map creation menu (A) on the main screen of the client terminal 300 as shown in FIG.

In this case, when the user selects the map creation menu A in the fourth step S4 (YES), the intellectual property information providing server 200 secondly selects the main word selected and input by the user as shown in FIG. 4A. It distributes on a patent map of a plane (S5). Here, the main word is a word or a combination of words, such as "SMS", "control channel search", "frequency modulation", and the like. Here, the main word is usually selected and input by the user. The main word shown in FIG. 4A may be determined by the user with reference to the search result shown in FIG. 3 in relation to mobile communication, or may be arbitrarily selected by the client based on other scientific and technical literature. have. That is, the method of selecting the main word in step S5 is manually selected by the user.

FIG. 4A illustrates a main word selected and input by a user on a patent map of a two-dimensional plane. In order to represent each main word on a two-dimensional plane, a random distribution method was used. This method is described below with reference to FIG. 8.

That is, in the fifth step S5, the intellectual property information providing server 200 distributes a plurality of main words on the patent map as shown in FIG. 4A by using a random number of computers. The method of distribution is as shown in FIG. First, a width W and a height H of a map are selected (S9), and two random numbers between 0 and 1 provided by most computers are generated (S10). In determining the coordinates of the main word, one random number is multiplied by the width of the X-axis on the map (W) to determine the X-coordinate for the arbitrary main word, and in the same way the other random number is the height of the Y-axis on the map ( By multiplying H), a method of determining the Y-coordinate for an arbitrary main word is taken (S11). In this way, the coordinates for all the main words are determined and displayed on the map (S12 and S13), thereby positioning each main word as shown in FIG. 4A.

The intellectual property information providing server 200 selects index words of respective intellectual property rights and determines coordinates (X, Y) of all intellectual property data according to the degree of correlation with each main word distributed on the patent map. 4B, it is positioned on the patent map (S6). At this time, the index word selection process of each intellectual property right is selected as follows using a text mining technique as shown in Figs.

A process of deriving the core index word using the text mining technique is illustrated in FIG. 9. First, the process of removing the incidental word through the process of controlling the incidental word in the text shown in the abstract, the representative claim, and the name (S14), excluding the affix and obtaining only the pure root (S15), and the obtained root. The frequency of appearance in the representative claim and name (S16), and the process of calculating the ranking for each root based on the appearance frequency (S17) can obtain the frequency of appearance by each root. When the roots thus obtained and the frequency of occurrence thereof are calculated and arranged, a table as shown in FIG. 10 is obtained. In this table, up to a certain rank, for example, the fifth rank is selected as an index of the intellectual property data.

The coordinates (X, Y) at which the index words of the respective intellectual property data selected in the patent map are located are determined using Equation 1 below.

,

,

Here, each subject word represents a subject word on a patent map previously shown as shown in FIG. 4A, and weights are used to index and select members of each intellectual property data selected using the abstract, representative claims, and names of the respective intellectual property data. A numerical value representing the correlation between each main word shown, which is differentially determined according to the index word shown in FIG. 10 and the frequency thereof calculated in advance for each intellectual property data. That is, the correlation between the words selected as the index word in FIG. 10 and the main word (FIG. 4A) of the object to be analyzed may be obtained by adding the frequency of the matching index word when the index word and the main word match. For example, as shown in FIG. 10, the index words are "voice recognition", "antenna", "code division", "location tracking", and "digital", and the theme song shown in FIG. 4A is "voice recognition" and "for convenience". It is assumed that there are only two "digital code division", and the position coordinates are "digital code division" (5.5, 4) and "voice recognition" is (0.5, 6). First, as a result of comparing the index word of a specific intellectual property data with the subject word "voice recognition", it is found that the index word "voice recognition" with the frequency 10 is the same as the subject word. In this case, the weight becomes frequency 10, As a result of the comparison with the "digital code division" and the index words "code division" with a frequency of 5 and "digital" with a frequency of 2, the weight becomes 5 plus 2 in this case. Fig. 7 summarizes these calculation results.

The coordinates (X, Y) of the specific intellectual property data whose index words are represented by FIG. 10 are determined as shown in Equation 2 according to Equation 1 above.

,

,

Therefore, the coordinates (X, Y) of the specific intellectual property data are (2.56, 5.18). When the coordinates are displayed on the patent map for all the intellectual property data retrieved as described above, the figure as shown in FIG. 4B is completed.

Subsequently, the intellectual property information providing server 200 calculates the number of times the number of forward citations of the plurality of intellectual property data located on the patent map is determined and ranks the number of times to the contour as shown in FIG. 4C. After binding, the completed patent map is displayed to the corresponding client through the client terminal 300 (S7). In order to calculate the number of times each intellectual property data is cited, "References Cited" can be used in the US patent publication, and "Reference" in the case of the Japanese patent publication. It is easy to calculate. In general, citing a particular intellectual property right means that the technology is influential.

  Here, the inside of the contour means that the number of citations is high, so that the ranking is high. The contour lines may use the same color, but the contrast is adjusted so that colors are gradually blurred from the highest contour to the lowest contour, so that a better three-dimensional effect can be obtained.

In this case, the plurality of intellectual property data located on the patent map may be represented by different figures by year or by applicant, as shown in FIGS. 5 and 6, or may be represented by different colors.

Meanwhile, after the seventh step S7, when the client places the cursor on a specific intellectual property data point located on the patent map, the intellectual property information providing server 200 determines the specific information from the prior art DB 120. It is more effective to read a patent number, abstract information or various related information corresponding to the data and display the same on the client through the sub screen B as shown in FIG. 5 or 6. 5 and 6 illustrate exemplary screens of a patent map displaying main words and intellectual property rights related to the keyword “mobile communication terminal” by major companies or by years.

On the other hand, the intellectual property information providing server 200 determines whether the user has selected the log-out (Log-out) through the client terminal (300) (S8), if not selected logout (NO) If proceeding to the second step (S2) again, if the log out is selected (YES), the authentication of the client terminal 300 is released and the search processing operation is terminated.

On the other hand, in the second step (S2), the user does not enter a search expression for the intellectual property information or a search value associated with it (NO), or in the fourth step (S4), the user makes a map creation menu (A). If (NO) is not selected (NO), the intellectual property information providing server 200 proceeds to the eighth step (S8).

Although the present invention has been described in more detail with reference to the examples, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

According to the patent map providing system and the method which can grasp the degree of correlation between the data according to the present invention as described above, the main words randomly placed a large amount of intellectual property data retrieved by the client on the two-dimensional map After determining and positioning the coordinates (X, Y) according to the degree of correlation with each other, and assigning the contour line by grade according to the number of citations of each intellectual property data located on the map, The trend of patent application by each patent, the closest literature search when searching for evidence of evidence, technology development by field and the degree of applicant's development by field can be grasped at a glance, thereby improving the search efficiency with convenience.
