Annotation collective dans le contexte RI : définition d'une plate-forme pour expérimenter la validation sociale

With the advent of the participative Web, digital document readers gain in expressiveness. Annotations systems enables them to comment, to rephrase, to criticize, etc. passages from any document. IR approaches that considered document contents only nowadays tend to exploit this participative dimension of the Web. Readers’ activity (annotations and related debates) may notably improve IR recall and precision. In previous works, we intended to integrate annotations into the IR process regarding their “social validation,” i.e. the confirmation degree expressed by the group who debated. This paper depicts an experimental platform aiming to compare the proposed social validation algorithms with the human perception of consensus. This ongoing experiment has been raising 173 participants; acquired data is under study. MOTS-CLÉS : RI, annotation, débat, validation sociale, expérimentation, perception humaine.
