As the system described in the report is very new, we have not measured important factors such as: gain of productivity, acceptance by users, recall and precision factors for the information retrieval system, etc. To measure all these factors, we intend to port an existing hypermedia application from the PC version of Microcosm to the cooperative version of Microcosm running on the Unix platform, and using a group of authors. We will compare the links created manually in the PC version with the links created by the group using the CSCW facilities and the information retrieval mechanism. We also intend to compare links created by the Compute Link functionality, and for image files comparison with the MAVIS project.
