If the check result is the thickness division mode, the server controller 213 detects this in step 1009 and proceeds to step 1011. In step 1011, the server controller 213 controls the content relevance graph generator 211 to classify the thickness of the keyword information (text information of the keyword) according to the priority. For example, when the keyword 'a' becomes the first rank, the keywords 'b' and 'c' become the second rank, and the keyword 'd' becomes the last rank, the keyword 'a' is treated as the most bold, The keywords 'b' and 'c' are treated as medium thickness, and the keywords 'd' are treated as thin thickness.

On the contrary, if the check result is the length division mode, the server controller 213 detects this in step 1013 and proceeds to step 1015. In operation 1015, the server controller 213 controls the content relevance graph generator 211 to distinguish and process the search keyword and the connection length of each keyword information according to the priority. For example, when the keyword 'a' becomes the first rank, the keywords 'b' and 'c' become the second rank, and the keyword 'd' becomes the last rank, the connection length of the keyword 'a' and the search keyword is determined. The shortest processing is performed, and the connection lengths of the keywords 'b' and 'c' and the search keyword are processed in the middle, and the connection length of the keyword 'd' and the search keyword is processed to be the longest.

In operation 1019, the server controller 213 generates keyword relevance graph information by applying keyword information classified according to the priority.

After generating the keyword relevance graph information, the server controller 213 controls the communication interface 201 and transmits the generated keyword relevance graph information to the user terminal 3 in step 917.

11 is a flowchart of an operation of searching for related content in a server according to an embodiment of the present invention. Referring to FIG. 11, an operation of searching for related content in a server is described. When receiving related content search command information from the user terminal 3 through the communication interface 201 in step 1101, a server controller ( 213 detects this in step 1103 and proceeds to step 1105. Here, the related content search command information includes the displayed corresponding content information.

In step 1105, the server controller 213 analyzes the related content search command information and proceeds to step 1107 to extract content information included in the related content search command information. In operation 1109, the server controller 213 extracts keyword information included in content information extracted from the related content search command information.

In operation 1111, the server controller 213 controls the content information DB 209 to extract related content information including at least one extracted keyword. For example, if the keywords extracted from the contents included in the related content search command information are 'a', 'b' and 'c', the keyword includes at least one of 'a', 'b' and 'c'. Extract relevant content information.

In operation 1113, the server controller 213 counts each keyword information included in the extracted relevant content information. At this time, if a plurality of identical keyword information exists in each of the extracted related content information, it is counted only once. For example, the keywords extracted from the content included in the related content search command information are 'a', 'b' and 'c', and the extracted related content 'B' is the keyword 'a'. 'A', 'b', 'c', the extracted related content 'C' includes the keywords 'b', 'c' and 'c', and the extracted related content 'D' has the keyword 'a' Is included, the content 'B' is counted as '3', 'C' is counted as '2', and 'D' is counted as '1'.

In operation 1115, the server controller 213 prioritizes the extracted related content information according to the counting number. For example, if the content 'B' is counted as '3', 'C' is counted as '2' and 'D' is counted as '1', the content 'B' is the first rank and the content 'C' is the second ranking, and content 'D' is the last ranking.

In operation 1117, the server controller 213 controls the communication interface 201 to transmit the priority-aligned content information to the user terminal 3.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the present invention should be defined by the claims and their equivalents.
