Apparatus, method and recording medium storing command for supporting learning

A method performed by an apparatus including a transceiver communicating with a user device, one or more processors, and one or more memories storing commands that cause the one or more processors to perform an operation when the commands are executed by the one or more processors, and information related to a plurality of problems, the method comprising:

• receiving, by the transceiver, a problem image of a first problem from the user device;
• extracting, from the problem image by the one or more processors, a first layout including an area of the problem image in which textual information of the first problem is located and a second layout including an area of the problem image in which illustrative information of the first problem is located;
• determining, by the one or more processors, a first similarity between the first layout and textual information of a second problem stored in the one or more memories;
• determining, by the one or more processors, a second similarity between the second layout and illustrative information of the second problem;
• determining, by the one or more processors, a third similarity between the first problem and the second problem by combining the first similarity and the second similarity;
• determining, by the one or more processors, whether the second problem corresponds to the first problem based on whether the third similarity is larger than or equal to a predetermined reference similarity;
• and
• upon determining that the second problem corresponds to the first problem, transmitting, by the transceiver, information indicating an answer or solution corresponding to the second problem to the user device.

A non-transitory computer-readable recording medium storing commands that cause one or more processors to perform an operation when the commands are executed by the one or more processors, the commands comprising:

• extracting, from a problem image of a first problem, a first layout including an area of the problem image in which textual information of the first problem is located and a second layout including an area of the problem image in which illustrative information of the first problem is located;
• determining a first similarity between the first layout and textual information of a second problem stored in one or more memories;
• determining a second similarity between the second layout and illustrative information of the second problem;
• determining a third similarity between the first problem and the second problem by combining the first similarity and the second similarity;
• determining whether the second problem corresponds to the first problem based on whether the third similarity is larger than or equal to a predetermined reference similarity;
• and
• upon determining that the second problem corresponds to the first problem, controlling a transceiver to transmit information indicating an answer or solution corresponding to the second problem to an user device.
