In advanced methods of delineation and mapping of scientific fields, hybrid methods open a promising path to the capitalisation
of advantages of approaches based on words and citations. One way to validate the hybrid approaches is to work in cooperation
with experts of the fields under scrutiny. We report here an experiment in the field of genomics, where a corpus of documents
has been built by a hybrid citation-lexical method, and then clustered into research themes. Experts of the field were associated
in the various stages of the process: lexical queries for building the initial set of documents, the seed; citation-based
extension aiming at reducing silence; final clustering to identify noise and allow discussion on border areas. The analysis
of experts’ advices show a high level of validation of the process, which combines a high-precision and low-recall seed, obtained
by journal and lexical queries, and a citation-based extension enhancing the recall. This findings on the genomics field suggest
that hybrid methods can efficiently retrieve a corpus of relevant literature, even in complex and emerging fields.
specification can further be informed on theoretical grounds.) Using quantiles and percentile ranks, the observed values can be tested against the expected ones using non-parametric statistics.

Going back to the ideal representation and assuming that an a priori fielddelineation of the whole set of publications is performed—i.e., publications are divided into groups associated with the
