PROBLEM TO BE SOLVED: To extract data effective at an output destination.SOLUTION: An output unit 13 filters inputted data according to each filter condition for filtering data and outputs a filtering result to an output destination 11. A reception unit 14 receives information indicating whether the outputted filtering result is appropriate/inappropriate from the output destination 11. An accumulation unit 15 respectively accumulates a number of times that the result is determined as appropriate or inappropriate for each filter condition on the basis of the received information. A switching unit 16 switches validity/invalidity of filtering in the output unit 13 for each filter condition, on the basis of values obtained by accumulating for the filtering condition the number of times that the outputted filtering result is determined as appropriate or inappropriate and according to a switching condition for switching validity/invalidity of the filter condition. |
