Research Collaboration: Discovering Analytical Concepts from User Profiles
This collaboration aims to provide a metadata foundation for the user assistance features for next generation BI systems.
We focus on making metadata to be considered and handled as first-class citizens for user-centric BI systems. In the novel settings, the user wants to analyze data coming from external and non-controlled data sources. Therefore, the metadata need to be designed in a flexible and reusable manner to be utilized in the context of these new and heterogeneous data sources. Thus, we want to explore and define metadata to support the user analytical needs in these settings.
- Definition of the framework for analytical metadata to support the user analytical needs.
- Collection and exploitation of metadata artifacts to provide user assistance for data analysis.
