To facilitate access to data mining techniques, particularly for non-specialists, the TDM (Text and Data Mining) service of Inist-CNRS is developing web services around the processing of scientific and technical information. These services can be called from the command line or within LODEX, a free viewing tool. The demonstration shows how, from the information in a bibliographic record and more particularly from an author's address, the RNSR identifier (National Directory of Research Structures) is automatically assigned to the initial document and how this new data is operated within LODEX. Thus, a program or algorithm developed by teacher-researchers could be adapted to become a web service and be used by as many people as possible.
