  • Publication number: 20220398486
    Abstract: The present invention is to predict a correct answer probability of a user for a specific question with higher accuracy, and provide learning content having more increased efficiency. A method for operating a learning content recommendation system includes transmitting question information including information on a plurality of questions to a user, receiving solving result information that is the user's response for the plurality of questions, and training a user characteristic model based on the question information and the solving result information, wherein the training of the user characteristic model includes assigning a weight to the user characteristic model based on a degree of influence on a correct answer probability in a sequence of questions input to the user characteristic model.

  • Patent number: 9875668
    Abstract: The present disclosures relates to a control terminal, comprising: a data communication unit for receiving a first user voice by data communication with a first audio device and receiving a second user voice by data communication with a second audio device; a turn information generating unit for generating turn information, which is voice unit information, by using the first and second user voices; and a metalanguage processing unit for determining a conversation pattern of the first and second users by using the turn information, and outputting a reminder message corresponding to a reminder event to the first user when the conversation pattern corresponds to a preset reminder event occurrence condition.

  • Patent number: 9792586
    Abstract: Provided is a system and method for perceiving an outcast in a group. The system may include: a plurality of member terminals held, respectively, by a plurality of members conducting an outdoor activity and configured to transmit waves with a radio frequency; and a leader terminal held by a leader of the outdoor activity and configured to receive the waves transmitted from the plurality of member terminals, to sense intensities of the waves, to obtain distances between the plurality of member terminals from the sensed intensities of the waves, to calculate a group distance based on the obtained distances between the member terminals, to sort the plurality of member terminals into at least one subgroup, and to determine an outcast member terminal excluded from the at least one subgroup.
