SEGMENT CREATION DEVICE, SEGMENT CREATION METHOD, AND SEGMENT CREATION PROGRAM

摘要

The present invention is provided with: a live broadcast data acquisition unit that acquires string data transmitted from a plurality of terminals, and that acquires live broadcast data, which is data that combines the string data and a data registration date/time, which is the date and time that the string data was acquired; a live-broadcast-data-quantity tabulating unit that, for each predetermined time unit, tabulates the number of live broadcast data sets having string data that matches search conditions input by means of an input unit; and a topic segment creation unit that creates segment data comprising the start time and end time of a continuous time period during which the number of live broadcast data sets tabulated by the live-broadcast-data-quantity tabulating unit was at least a predetermined threshold.
