In this paper, we present an original methodology making scientometric analysis based on three dimensions (spatial, temporal and thematic). This methodology includes 3 steps: (1) preparation and validation of data in order to complete usual criteria such as author names, affiliation, . . . by spatial, temporal and thematic ones; (2) the indexating of the contents of the publications and associated metadata; (3) analysis and/or multidimensional information retrieval. Expriments are conducted on EGC conferences from 2004 to 2015.
