Abstract
The use of databases which contain an increasing number of references leads to a new concept in online retrieval. Because the number of answers increases with time, it is in many cases too important to be analysed by simple reading. Various hosts have introduced some sorting techniques on one reference field such as GET, ZOOM, MEM, but these techniques are not powerful enough to give to the reader a fast overview of the content of all the answers. This is the reason which prompts the CRRM to develop various analytical techniques to perform an automatic analysis of the answers obtained by the use of online databases. These techniques, co-word techniques and typological aspects of the information, will certainly be part of those which will be offered to the online user in the near future.
