[0054] On question boards, users may use precise names to identify a specific electric vehicle (EV) charging station, but they may also post vaguely specifying it as a station of a certain brand in a certain region. In such cases, it is necessary to accurately identify which EV charging station the question, answer, or comment pertains to in the first place.

[0055] In this regard, the electric vehicle charging station automatic identification module (307) can identify an electric vehicle charging station by referring to an address or brand, etc., on the electric vehicle charging station database (302) through the real-time analysis results of the text analysis module (305). As another example, the electric vehicle charging station automatic identification module (307) can identify an electric vehicle charging station by searching for signboard images of questions, answers, and comments in the electric vehicle charging station street view image database (304) and confirming which electric vehicle charging station the signboard image belongs to.

[0056] The electric vehicle charging station identification code database (308) can be configured to store electric vehicle charging station identification codes. Since electric vehicle charging stations are difficult to specify or identify by their brand or vaguely described location or name, the electric vehicle charging station identification code can be configured to be assigned separately to each electric vehicle charging station and used on an online bulletin board.

[0057] The electric vehicle charging station identification code automatic verification module (309) can be configured to verify the electric vehicle charging station identification code of the electric vehicle charging station automatically identified by the electric vehicle charging station automatic identification module (307) in the electric vehicle charging station identification code database (308).

[0059] The question / answer / comment automatic classification module (311) can be configured to automatically classify questions, answers, or comments based on the electric vehicle charging station identification code verified by the electric vehicle charging station identification code automatic verification module (309) or the electric vehicle charging station identification code automatically assigned by the electric vehicle charging station identification code automatic assignment module (310). Through this, all questions, answers, and comments can be classified by electric vehicle charging station based on the electric vehicle charging station identification code.

[0060] The question / answer / comment database (312) by identification code can be configured so that questions, answers, or comments automatically classified by the question / answer / comment automatic classification module (311) are stored based on the electric vehicle charging station identification code.

[0061] The question / answer / comment reliability analysis module (313) may be configured to analyze the reliability of questions, answers, or comments stored in the question / answer / comment database (312) by identification code using the real-time analysis results of the text analysis module (305) or the real-time analysis results of the image analysis module (306).

[0062] Reliability can be analyzed in various ways, specifically as follows.

[0063] The question / answer / comment reliability analysis module (313) determines whether the answers or comments with mutually matching content are answers or comments to different questions, and if the content of the answers or comments to different questions matches as a result of the determination, the reliability can be analyzed as higher the more such cases there are. That is, even if the content of the answers or comments to the same question matches each other, the reliability can be evaluated as high, but if the content matches even in answers and comments to different questions, the answers or comments can be evaluated as even more reliable.

[0064] And the question / answer / comment reliability analysis module (313) determines whether there are answers or comments with mutually inconsistent content within a predetermined period range, and if the result of the determination is that they exist within the predetermined period range, it may be configured to analyze the reliability of the answers or comments with a large number of mutually consistent answers or comments among the answers or comments as high. When there is a large difference in the time when the answers or comments were written, there may be many cases where the actual situation or facts have changed. For example, the number of chargers may have been 4 a year ago, but now it may have been expanded to 10. In such cases, the longer the difference in time between the written posts, the more likely the mutual inconsistencies in content may correspond to the factual relationship. However, if the difference in time between the written posts is short, one of the mutual inconsistencies in content may not correspond to the factual relationship. Accordingly, if the difference in time between the written posts is short and the content is inconsistent with each other, the reliability of the corresponding post may be analyzed as low.

[0065] And the question / answer / comment reliability analysis module (313) can be configured to analyze the reliability of a given user's answer or comment as low as there are more counter-comments.

[0066] The user reliability analysis module (314) may be configured to analyze the reliability of the user who wrote the question, answer, or comment stored in the question / answer / comment database (312) by identification code using the real-time analysis result of the text analysis module (305) or the real-time analysis result of the image analysis module (306).

[0067] Specifically, it is as follows.

[0068] The user reliability analysis module (314) may be configured to analyze the reliability of users as low if the number of answers or comments analyzed as having reliability lower than a predetermined standard is greater than a predetermined standard, based on the analysis results of the question / answer / comment reliability analysis module (313).

[0069] The user reliability analysis module (314) can be configured to analyze the reliability of a given user's answer or comment as low as there are more counter-comments to that answer or comment.

[0070] The electric vehicle charging station reliability analysis module (315) may be configured to analyze the reliability of the electric vehicle charging station that wrote the question, answer, or comment stored in the question / answer / comment database (312) by identification code using the real-time analysis result of the text analysis module (305) or the real-time analysis result of the image analysis module (306).

[0071] For example, the electric vehicle charging station reliability analysis module (315) may be configured to analyze the reliability of a given electric vehicle charging station as low as there are more counter-comments to that answer.

[0072] The AI ​​learning module (316) can be configured to learn information related to electric vehicle charging stations stored in the electric vehicle charging station database (302) and maps indicating the locations of electric vehicle charging stations stored in the electric vehicle charging station map database (3053).

[0073] And the AI ​​learning module (316) can be configured to learn questions, answers, or comments stored in the question / answer / comment database (312) by identification code based on the reliability of the questions, answers, or comments analyzed by the question / answer / comment reliability analysis module (313), the reliability of the users analyzed by the user reliability analysis module (314), and the reliability of the electric vehicle charging station analyzed by the electric vehicle charging station reliability analysis module (315). That is, the AI ​​learning module (316) can perform learning on the answers or comments by referring to the reliability.

[0074] The AI ​​chat module (317) can be configured to perform chatting with the user terminal (100) by an AI algorithm based on the learning results of the AI ​​learning module (316). That is, the AI ​​chat module (317) can directly answer the user's questions using the learning results of the content of the online bulletin board, and the user can hear the answer without asking a question on the question board, and there is no need to search for the content they want to know while searching the question board.

[0075] The electric vehicle charging station identification code additional display module (318) can be configured to add and display the corresponding electric vehicle charging station identification code to the questions, answers, or comments on the question board that correspond to the questions, answers, or comments stored in the question / answer / comment database (312) by identification code. Through this electric vehicle charging station identification code, it is easy to recognize which electric vehicle charging station the question, answer, or comment relates to, and questions, answers, and comments related to a specific electric vehicle charging station can also be easily searched through the electric vehicle charging station identification code.

[0076] The question / answer / comment reliability additional display module (319) may be configured to display additional reliability on answers or comments on a question board corresponding to each question, answer, or comment stored in the question / answer / comment database (312) by identification code, based on the reliability of a question, answer, or comment analyzed by the question / answer / comment reliability analysis module (313), the reliability of a user analyzed by the user reliability analysis module (314), and the reliability of an electric vehicle charging station analyzed by the electric vehicle charging station reliability analysis module (315). Users can view and refer to the reliability displayed for numerous answers or comments on the question board.

[0077] The automatic cleanup module (320) for the question board may be configured to automatically delete answers or comments that have a reliability level below a predetermined standard based on the reliability of the questions, answers, or comments that are additionally displayed on the question board by the question / answer / comment reliability additional display module (319). By this configuration, the reliability of the question board can be increased by deleting posts that are indiscriminate, do not correspond to the facts, or are falsely written, and the accuracy and efficiency of the AI ​​learning results can also be increased.

[0078] Meanwhile, an electric vehicle charging station question board method according to another objective of the present invention may be configured to include the steps of: a user terminal (100) writing a question related to an electric vehicle charging station on a question board and uploading it to an electric vehicle charging station question board server (300); the electric vehicle charging station question board server (300) posting the question uploaded to the question board from the user terminal (100) in real time; and the electric vehicle charging station question board server (300) providing a connection path that enables direct access to the electric vehicle charging station for the question on the question board.

[0079] Here, the electric vehicle charging station terminal (200) may be configured to further include the step of writing and uploading an answer to a question uploaded to a question board.

[0080] And the electric vehicle charging station question board server (300) may be configured to further include a step of posting answers uploaded to the question board from the electric vehicle charging station terminal (200) in real time.

[0081] Although the invention has been described with reference to the above embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
