Wikipedia is the user contributed encyclopedia edited collaboratively by a wide-range of people. Wikipedia usually determines contents of article and editorial policies through discussion among participants. It requires a lot of effort in deducing its conclusion often due to protracted discussion. We need some measurement to examine how discussion is valuable to reach conclusion. So, we call it discussion validity and define it with the model with discussion capability of participants. Discussion capability of participants consists of three features each of which represents characteristic aspect of users' behavior in discussion, and approximated from the corresponding three features of their utterances. We conducted the experiments with the subjects to verify the model and found that our model resulted better than the conventional model and proposed the automatic prediction of discussion validity using the text analysis. Then we estimated discussion validity through the model with the estimated values. It turned out that the estimation was well fitted with the values by the subjects.
