The problem classification unit 310 may classify problems included in a plurality of pre-registered worksheets by learning part or problem type and store them in the database 380.

Here, worksheets are learning aids organized by grade or progress for learning activities, and are generally composed of a theory and a plurality of practice problems that confirm the theory. The worksheets may be in the form of a data file that can be transmitted online, and each workbook may be received from the server 200 of a publisher (or distributor) that publishes or distributes the worksheets and registered in the database 380.

For example, worksheets are information in the form of text, which can be provided directly from a publisher in the form of an electronic file or obtained by scanning the contents of a published book using optical character recognition (OCR). .

The registration information of the workbook registered in the database 380 may include the title of the workbook, author, classification code, table of contents, publication date, bibliographic information including revision date, and main text.

Additionally, the learning service providing server 300 may receive data files for each problem constituting the workbook from the publisher server 200.

The problem classification unit 310 divides the problems included in the worksheets received from the publisher server 200 by the workbook name, publisher, publication year, and learning stage (grade, semester, etc.), and issues included in the workbooks thus classified. They can be classified and extracted by learning part or problem type and stored respectively in the database 380.

Information on the learning part and problem type of each problem may be received from the publisher server 200, and may be obtained by analyzing the problem by the problem classification unit 310 itself.

For example, the problem classification unit 310 can recognize the words that make up the problem, predict which learning part the problem belongs to, and recognize the words that make up the problem, the arrangement of the views, and the pictures included in the problem. This allows you to predict what type of problem it is.

The learner management unit 320 is configured to store and manage information for a plurality of registered learners, such as name, date of birth, contact information, selected instructor, course schedule, learning history, etc., on the database 310.

In particular, the learner management unit 320 may select the learner's weak parts or weak problem types based on the results of the learner's self-filled questionnaire.

Here, the self-administered survey result may refer to the result of the learner entering an answer when the learning service providing server 300 provides the learner terminal 100 with a survey item in which the learner self-enters the answer. .

At this time, the survey items may include various questions to select the learner's weak part or weak type.
