Abstract: The present invention relates to a method, system and non-transitory computer-readable recording medium for assisting listening study. According to one aspect of the invention, there is provided a method for assisting listening study, comprising the steps of: determining a plurality of weak study sentences that a user who is provided with assessment study sentences by speech fails to understand, with reference to feedback from the user; determining at least some of pronunciations or pronunciation combinations commonly included in the plurality of weak study sentences as weak pronunciations or pronunciation combinations that the user fails to understand; and determining a compensatory study course to be provided to the user, with reference to the determined weak pronunciations or pronunciation combinations.

Abstract: A method for providing information on a user's concept understanding is provided. The method includes acquiring a set of data on a user's understanding of concepts including a first concept estimated using a concept-specific understanding estimation model that is trained on the basis of concept-specific correctness/incorrectness sequence data, estimating the user's understanding of a second concept not encountered by the user using a matrix factorization algorithm on the concept-specific correctness/incorrectness sequence data represented in a matrix structure with respect to the first concept and the second concept, and visualizing the user's understanding of the first concept included in the acquired data set and the second concept on a device of the user. The concept-specific understanding estimation model is trained such that the concept understanding is estimated by assigning a greater weight to a piece of the concept-specific correctness/incorrectness sequence data generated at a later time point.

Abstract: A method for providing a correctness/incorrectness prediction for a learning question is provided. The method includes the steps of: acquiring a set of data including a user variable determined on the basis of concept-specific correctness/incorrectness sequence data of at least one user, and at least one variable related to a question and a concept associated with the user variable; and calculating a probability that a first user corresponding to a specific user variable correctly answers a first question corresponding to a specific concept, with reference to the data set.

The method includes the steps of: acquiring a set of data on a user's concept understanding estimated using a concept-specific understanding estimation model that is trained on the basis of concept-specific correctness/incorrectness sequence data; and visualizing the user's understanding of at least one of concepts included in the acquired data set.

Abstract: A method for estimating concept understanding is provided. The method includes the steps of: generating concept-specific correctness/incorrectness sequence data with respect to at least one user, with reference to data on a result of the at least one user solving at least one question associated with at least one concept; and estimating a first user's understanding of a first concept using a concept-specific understanding estimation model that is trained on the basis of the concept-specific correctness/incorrectness sequence data.

Abstract: The present invention relates to a method, system, and non-transitory computer-readable recording medium for supporting learning. According to one aspect of the invention, there is provided a method for supporting learning, the method comprising the steps of: acquiring a learner's score for at least one assessment item included in a scoring table, wherein the learner has solved a question for learning and the scoring table is applied to a descriptive answer of the learner; determining a weak learning element of the learner with reference to the acquired score and at least one learning element associated with the at least one assessment item; and determining a supplementary learning path to be provided to the learner with reference to the determined weak learning element.

Abstract: Method for indicating characteristic of problem set including a plurality of problems is provided. The method comprises a step of determining characteristics of problems, wherein characteristic of each problem included in said problem set is determined by attributes related with each problem and correlations between said attributes; and a step of determining characteristic of problem set, wherein characteristic of problem set is determined as a union of characteristics of all problems included in said problem set, and said characteristic of problem set is determined by attributes related with all problems and correlations between said attributes.
