  In this paper, we propose a study of progressive development of the structure
of corpus collected starting from the discussion forums. These are the first
results from an ethnographic description of constitution and analysis practices
of a corpus located within an interdisciplinary project. At first, we describe
the personal digital documents folder of a researcher, relative to his corpus
analysis of interactions of social support online. Next, we examine the
constitution of a shared corpus, result of the pooling of individual corpora,
small size, produced by researchers participating in the project, each
individual corpus reflecting his producer's perspectives of research.
