Visual Data Mining System

Objective

The aim of VITAMIN S project is to go beyond products and experience gained through involvement in other projects by designing an interactive environment for graphical data analysis, that offers innovative visualization and enhanced graphical data analysis methods, useful for users, statistician or not. Indeed, visual inspection can be considered the basic step of exploratory data analysis process.
Using directly the obtained results as input for more complex numerical analysis, they allow a considerable reduction of such method computational cost. The system will provide linking between visualization methods where possible, so that the full potential of several visualization methods is used at the same time by the user during the analysis process.

Objectives:
The objectives of VITAMIN S are:
1. Enhancement of classical graphical data analysis methods by incorporating dynamic and interactive techniques;
2. Implementation of innovative visualisation methods;
3. Some possible fields for methodological developments can be related to: NSI's typical data such as: Structured Data both at disaggregated and aggregated level, Time Series, and Spatial Data;
4. Integration of the implemented graphical and visualisation methods into a unique and homogeneous environment for a genuine Visual daTA MINing System (VITAMIN-S) by:
- offering classical and innovative visualisation tools;
- providing an interactive framework to explore multivariate data;
- linking displays, so that the full potential of several visualisation methods can be used at the same time during the analysis process;
- providing interactive reports that trace the data exploration steps.

Work description:
The fulfilment of the project objectives requires under the two phases the following actions:

Phase A:
- Identification of the needs of NSIs and end-users in relation to data exploration using visualisation methods;
- Analysis of existing literature related to graphical methodologies in statistics, and finally assessment of s/w tools in an attempt to identify possible weakness on visualisation techniques;
- Propose and define the functional specifications of enhanced classical graphical methods as well as propose innovative visualisation methods.

This will be done based on concrete criteria such as:
- user group requirements like:
1) need to help in the data exploration of specific data sets;
2) usefulness;
3) applicability and generality;
4) degree of existing software coverage;
5) willingness of potential customers to pay

- resources available;
- suitability for future commercialisation;
- Design a prototype demonstrating a visualisation method by using specific data sets (the ISTAT Multiscope Survey, and the time series database of the ONS).

Phase B:
- Evolution of the prototype into the proposed full-blown VITAMIN-S system;
- Validation and verification of project objectives;
- Exploitation of results.

In both phases careful management of project resources and efficient co-operation among them will be maintained.

Milestones:
1. Accurate capture of user requirements;
2. Propose innovative visualisation methods;
3. Development of a prototype;
4. Develop of the fully-blown VITAMIN-S system;
5. Consolidation of the achieved results and gain of the acceptance of the users;
6. Enlargement of the potential user's basis;
7. Assuring of the commercial viability of the system.
