In this article we propose to use the conflict in the context of the belief functions theory in order to assess the quality (called here the relevance) of an information source. We study two measures of conflict proposed in two similar approaches that aim to assess this quality of an information source. Empirical tests show that both measures give globally close results and that the notion of relevance improve the classification.
