PPROBLEM TO BE SOLVED: To provide an inquiry type learning device for constituting a precise classifier for inquiry type identification. PSOLUTION: An identity characterizing an inquiry type is extracted from a learning sample of an inquiry, using a word attribute N-gram, by a feature extracting part 1. Then, an identity space is constituted based on the extracted identity by an identity vector preparing part 2 to convert each inquiry into an identity vector. At last, the classifier is constituted to identify the type of inquiry when an unknown inquiry is input, based on the identity vector, using a support vector machine, by a classifier constituting part 3.
