Abstract: This communication presents a modular arrangement of lexical and 
citation operations to achieve a satisfactory delineation of a scientific 
field. Three querying methods are considered: on journals, on articles 
vocabulary, and on citation network. Rather than associating these 
querying modes, we consider possible sequences that make the best use of 
each method. At any stage of iteration, the retrieved set can be enhanced 
by either a citation-based analysis. or a vocabulary analysis (relative 
dictionaries), in order to reduce silence or noise. General noise-
reduction techniques, such as clustering, are applicable at various points 
of the procedure. A particular sequence on a complex field (nanosciences) 
is described, starting with journal and lexical query, then applying a 
citation expansion with a final lexical adjustment. Another sequence is 
sketched, starting with an additional journal-based procedure.
