Bottom-up scientific field detection for dynamical and hierarchical science mapping

David Chavalarias Jean-Philippe Cointet Target Documents :  ScienceMaps 2002-2003 with only most generic terms as label Target Articles : Chavalarias D., Cointet J-P, Detecting epistemic fields dynamics from a scientific content database (pre-print, to appear in Scientometrics) BROWSE THE WHOLE CS SCIENCE MAP ON CSS

Objectives : To develop new methods in order to detect paradigmatic fields thanks to simple statistics over a scientific content database.
We have defined an asymmetric paradigmatic proximity between concepts which provide hierarchical
structure and we have tested our methods on a case study with a database of 20 000 000M article. We also propose overlapping categorisation to describe paradigmatic fields as sets of concepts that may have several different usages. Concepts can also be dynamically clustered provinding a high-level description of the evolution of the paradigmatic fields.

Domains of application :

• Identification of paradigmatic fields defined as ordered keywords clusters.
• Do not deals with authorship.
• Need large corpuses indexed.

Required:

• Indexation of a database : occurences and co-occurences of words on several time periods (e.g. years).

Advantages :

• No semantic study needed
• No particular parsing needed
• Work on full text
• Work on large corpus (several million)
• Overlapping categorisation

Examples : one of the Clusters around learning

Taxonomies of epistemic communities

Application of Galois lattices (or concept lattices) to the dynamic rebuilding of taxonomies, and more particularly the structure of epistemic communities and their organization into hierarchical fields and subfields, with overlapping categories. Case studies have been carried on on embryologists working on the zebrafish, as well as ECCS 2005 and 2006 proceedings.
