The aim of the project is to use Symbolic
Data Analysis to solve problems of Statistical Offices,
in particular problems of confidentiality and missing data.
The project allows adaptation of statistical concepts
to the dynamical global environment, suggests methodology
of treatments and gives guidance on understanding
Special attention is given to background knowledge and modelling
of statistical metadata in order to provide a "meaning"
to the data, thus avoiding false interpretation due to data
misunderstanding and ensuring the quality of statistical results.
The ASSO project is the continuation of the SODAS
project done as part of the European Esprit project no.
20821. This first project has resulted in a software prototype
SODAS for the building and the analysis of symbolic
data and has shown the interest of the proposed methods for
administrative data. For more information on the SODAS
project, see (in French)
In addition to the objectives of SOSAS project, the ASSO
- extends standard data analysis to more complex data using
proper statistical metadata modelling techniques to ensure
the quality of statistical results,
- gives better explanation of statistical results by new
- gives new tools for concept creation, manipulation and
dissemination in order to get better and easier communication
between community members.
The SODAS2 software improves SODAS in order
- to render it more operational and attractive following
the users requests,
- to add new innovative methods and
- to demonstrate that these techniques meet needs
of Statistical Offices.
