Priscilla is one of the #DigitAg co-funded PhDs

Selecting pesticidal plants for animal and plant health in Africa using exploratory conceptual navigation

  • Start Date: November 2018
  • University: Montpellier University of Excellence
  • PhD School: I2S – Information, Structures, Systèmes
  • Field(s): Computer Science
  • Doctoral Thesis Advisor: Marianne Huchard, Université de Montpellier (LIRMM)
  • Co-supervisors : Marianne Huchard, Université de Montpellier (LIRMM), Pierre Martin et Pierre Silvie, Cirad AIDA

Keywords: pesticides plants – Data Mining – Data exploration – Data navigation – Visualization – human-machine interactio


Cirad develops several knowledge bases, including PPAf (project Knomana 2017-2018, métaprogramme Glofoods) which gathers usages of plants for animal and vegetal health. The gathered knowledge is useful for identifying alternatives to chemical pesticides and to chemical antibiotics for culture and breeding. As many different knowledge kinds are involved (taxonomy, geography, reliability of information sources, etc.), the knowledge visualization and exploration by end users (farmers, scientists, decision-makers, etc.) is complex. The thesis aims to elaborate a general methodology, theoretical tools and a prototype tool to answer the following questions: – Which is the best support for integrating and representing PPAf knowledge? – Which data mining techniques will be adapted to analyze the existing knowledge (decision trees, association rules, formal concept analysis)? – Which human-machine interaction method would allow different users with different profiles to express queries and analyze knowledge on-the-fly according the navigation context?
