Abstract
A method in which a server recommends a word to a user according to the present specification, includes receiving training data from a network and training an AI model by using the training data; inputting (1) a user vector and (2) a word vector to the AI model, and generating (1) a user embedding vector and (2) a word embedding vector for determining whether the user knows a word related to the word vector, on the basis of the trained AI model; inputting (1) the user embedding vector and (2) the word embedding vector to a function for determining whether the user knows a word related to the word vector; and outputting a result value for predicting whether the user knows a word related to the word vector from the function.
