Information Mining in Astronomical Literature with Tetralogie
D. Egret, Josiane Mothe, Taouq Dkaki, Bertrand E. Dousset · 1998
A tool derived for the technological watch (Tetralogie 3 )i s applied to a dataset of three consecutive years of article abstracts pub- lished in the European Journal Astronomy and Astrophysics .T his tool is based on a two step approach: rst, a pretreatment step that extracts elementary items from the raw information (keywords, authors, year of publication, etc.); second, a mining step that analyses the extracted in- formation using statistical methods. It is shown that this approach allows one to qualify and visualize some major trends characterizing the current astronomical literature: multi-author collaborative work, the impact of observational projects and thematic maps of publishing authors.
