Abstract

The goal of the Système Prototype Historique des Études et RÉcherche project (SPHERE) was to build an information system to archive and query the history of the activity of the Research Centre of Electricité des France (EDF). 2 directions were explored in the project: the construction of a relational database to gather and store all information available about the activities of EDF since 1980, and the sedign of generic tools to help to extract both detailed and synthetic information from this database. A data dictionary approach was used to administer and query the database, since its structure is very complex and is subject to continuous evolution and change. Special attention has been given to the processing of textual data: an automatic indexing process structures the textual data by extracting keywords from them, a text linker automatically finds related texts, and a text classifier classifies texts automatically into predefined classifications. Notes the practical applications of the database and points out the problems that remain unsolved, such as enabling a wider group of people to use the system
