Golf swing analysis system, golf swing analysis method, and information storage medium

A receiving unit () receives a message transmitted from any one of the users that are talk targets. The interpreter () attempts to interpret, as an answer to a question, the message received by the receiving unit (). A collector () collects, upon success of the attempt made by the interpreter (), the interpreted answer as the answer from the user who sends the message. When a predetermined requirement is satisfied in a state where a yet-to-respond user whose answer is not yet collected by the collector () is present, an inquiry transmitter () transmits an inquiry about the question to at least the yet-to-respond user among the users. A result transmitter (), after the answers are collected from all of the users, transmits to the users a message indicating a result obtained by tallying the answers.
