METHOD, DEVICE AND COMPUTER PROGRAM FOR ANALYZING DATA

WIPO Patent Application WO/2018/212396

A1

The present invention relates to a method for establishing a diagnostic question set, of a data analysis framework, for a new user, the method comprising: step a of establishing a question database including a plurality of questions, of collecting solving result data of the user for the questions, and of applying the solving result data to the data analysis framework, thereby calculating modeling vector(s) of the questions and/or the user; step b of extracting, from the question database, at least one candidate question for establishing the diagnostic question set; step c of identifying a user for whom solving result data for the candidate question exist, and another question for which solving result data of the user exist; step d of applying only the solving result data of the user for the candidate question to the data analysis framework, thereby calculating a modeling vector of a virtual user; step e of applying the modeling vector of the virtual user, thereby calculating a virtual correct answer probability for the another question; and step f of comparing the virtual correct answer probability with the actual solving result data of the user for the another question, and averaging the comparison result according to the number of the users, thereby calculating a predicted probability for the candidate question.
