Current methods for evaluating research are based on counting the number of citations received for publications. Thus, the more an article is cited and the more its impact is considered as important. In this article, we propose a new method for assessing the reputation of scientific journals, based on a web application in which the votes of expert researchers are gathered. The voting results indicate degrees of preference for a journal over another. Our system uses, in addition, the publications of an expert in order to quantify his expertise in specific fields. These values are coupled with those of votes to determine the pertinence, according to the field, of each journal in each topic. An iterative process of transferring values given to journals by experts to values of the experts themselves given their publications is used.
