Similarities induced by a comparability mapping : meaning and utility in the context of the clustering of comparable texts. In the presence of bilingual comparable corpora it is natural to embed the data in two distinct linguistic representation spaces in which a "computational" notion of similarity is potentially defined. As far as these bilingual data are comparable in the sense of a measure of comparability also computable (Li et Gaussier, 2010), we can establish a connection between these two areas of linguistic representation by exploiting a weighted mapping that can be represented in the form of a weighted bidirectional graph of comparability. We study in this paper the conceptual and practical consequences of such a similarity-comparability connection, while developing an algorithm (Hit-ComSim) based on the concept of similarities induced by the topology of the graph of comparability. We try to evaluate the benefit of this algorithm considering some preliminary categorization or clustering tasks of bilingual (English/French) documents collected from RSS feeds. MOTS-CLÉS : Graphe de comparabilité, Similarités induites, Documents comparables, Clustering.
