March 16th meeting

Thank you to Elisa who wrote the first version of this report.


Guillaume Daudin, Béatrice Dedinger, Pierre Gervais, Paul Girard, Guillaume Plique, Grégory Tible, Elisa Maria Tirindelli, Du Meng Ying

1) Database
We have now a new version of normalisation orthographique. We discuss the integration of the work of GD, GP, PG, and ET.
We also have a new version of «simplification».
GD will be working on a new SITC before Cambridge.

We know have a more-or-less working datascape at :
If you want to explore it, please ask Guillaume Daudin for access codes.

2) Ricardo
The paper was accepted and Ricardo will be presented in July. Du Meng Ying is doing her internship on Ricardo at present.
Major work to be done on Ricardo:
– Correcting bugs and adding new views (like the metadata in toflit).
– Creating a flow of data, converging to what was done in toilet. Transferring everything in a github account.

The breakdown into sources is still to be done.

We discuss the integration of an additional « world» trade estimate.

3) Merchandise treatment

– Normalisation orthographique is nearly done. It classifies 44,000 items into 21,000 groups. The only data missing are the data that have not been acquired yet. According to Loic there are 25% more lines to be done, even more according to Pierre.

– Simplification brought normalisation down to 16,500 lines. It still needs to be revised in detail because it still contains some old version of the work. Pierre suggests to organise a group meeting to talk about it and to work on it in a more organized way.

– Original orthographique needs to be cleaned. some products are still unknown and it is necessary to understand what they are. Pierre says they are not many.

– Catégorisation issue:

Pierre G. is of the opinion that the 1789 categorization (c. 250 categories) is not very coherent and might not work well on the entire dataset.

Guillaume D. suggested to use categorization 1788 because it contains all the data and in addition it links XVIII to XIX century data.

Pierre is skeptical, in his opinion we are looking for categories that will be useful to economists and economic analysis and maybe the best idea would be to come up with a new proposal of classification in the style of 2 digit sitc.

In the end, we decide to work directly on a 20 groups categorization (sitc18_rev3). GD is to do the job (he needs it for Cambridge !)

4) The June meeting in  Chicago project is cancelled. We will try to do an other in December or late winter. We will try to re-use part of our ideas for the 2018 Boston WEHC conference ?

5) Schedule for next meetings :
–  13 April 13  14.30, room 84 rue de Grenelle
– 11 May 16.00, medialab
– 8 June 9.30, medialab
– 1 July 9.30, medialab

6) Paul suggests to do a “for paper sprint” in July (1st ?) or September to provide data generation and exploration specifically need to paper in progress. We need to discuss that.

7) 2018 Boston WEHC conference : do a BYOD (we need to contact organizers). Or maybe a big database thing with Berlin ?
