摘要

A dynamic topic analysis system, a dynamic topic analysis method, and a dynamic topic that can estimate and output the topic activity when all of the periods and texts to be subjected to dynamic topic analysis are input without inputting them. A medium recording an analysis program is provided. In the text data or period to be subjected to the dynamic topic analysis, the missing situation input means 3 for inputting information about the data or period not inputted from the text data input means 2 to the missing situation storage means 106, and the activity of each topic Read the time series data and the data missing status, perform the activity time series data of each topic in the period where the data is missing, and perform the interpolation or prediction, when the topic activity level when there is no data missing A time-series interpolation prediction unit 107 that estimates the value of the series data and outputs it to the interpolation prediction result storage unit 108;
