Programme > Day 1


This first SAGES day will be divided into four sessions.

This is a preliminary program subjected to change

 

9:00 to 10:30

Session 1: Graph Theory

2 presentations of 35 minutes + 10 minutes of questions

Objective: contextualization + a theoretical part for the presentation of the stages of the standardization of the biodiversity data (define a descriptor, the existing formats, the links between descriptors, types of descriptors (numerical, formats, range values...) and their uncertainty, and how all this can be transposed into a graph)

-        History of the graphs (opening of the day) Solicitation in progress

-        Graph theory and algorithms, why this is not a "press button" tool

 


10:30 to 10:50: PAUSE coffee - discussion

 

10:50 to 12:30

 

Session 2: Data mining algorithms

Objective: To show the possibilities of prospecting on graphs and hypergraphs.


12:30 to 13:30: Lunch break

 

13:30 to 16:30

Session 3: Concrete cases and visualization results

Objective: To present and evaluate the first concrete cases supported in the different stages leading to the visualization of the data and to obtain the opinions of the theoreticians on the best methods of data mining and analysis of these graphs.

6 presentations of 15 minutes + 5 minutes of questions

-           13:30 at 13:50 Metadata of the Ecoscope portal
A. COHEN NABEIRO and / or A. DELAVAUD: Graphs to organize actors and improve the quality of information systems (+ prospects for graph enrichment using EBVs in this framework)

-           13:50 to 14:10 Marine data (Case Devotes and cases Cigesmed)
R. DAVID: The graphs in the marine environment, from molecular to remote sensing?

-           14:10 to 14:30 Scale-up with GBIF-France data
Perspectives of large-scale graphs in ecology

-           14:30 to 14:50 ArcheoGIS data
L. BERNARD: Will graphs revolutionize archaeological prospecting?


14:50 to 15:10 PAUSE coffee - discussion

 
-           15: 10 at 15:30 Data from the EPB - European pollen database
M. LEYDET - R. DAVID: How pollen can contribute to interdisciplinarity thanks to graphs

- 15:30 to 15:50


- 15:50 to 16:20


- 16:20 to 16:50

 

PAUSE coffee - discussion

 

 
17:10 to 18:00

Session 4: How to choose data mining methods

Objective: initiation of a decision tree containing the cases presented and theoretical cases

Debate on the algorithms according to the concrete cases presented
Possibility of using the grid (France Grid / EGI) / intensive computing and computing
