4 Two research teams The DIS team s research mainly focuses on complex data (texts, social networks, Web data...) warehousing and on-line analysis processing (OLAP) in various domains. The team aims at designing new warehouse models that are user-centric, efficient and secure. For this sake, we rest on methods from the fields of databases, data mining, information retrieval and service technologies at all levels of the warehousing process: data integration (ETL), multidimensional modeling and OLAP. The main topics we address are text data warehouses, social OLAP and personalization. Moreover, to devise solutions to big data storage and analysis issues, the team investigates business intelligence in the cloud (cloud analytics), including NoSQL databases and on-demand OLAP.

5 The DMD team s objective is to design new systems, models and algorithms for complex data mining and decision support. Complex data are heterogeneous, diversely structured, voluminous, imprecise and dynamic. decision - making communities machine WEB learning opinions decision - making COMPLEX data social media graphs data mining statistics D social media texts COMPLEX data texts artificial intelligence multiobjective optimization multicriteria aggregation uncertainty data mining social statistics media association opinionsd rules multicriteria aggregation graphs uncertainty machine learning decision - making M WEB opinions communities clustering multiobjective optimization machine learning artificial intelligence WEB graphs association rules texts clustering statistics multicriteria aggregation data mining To manipulate such data, the team rests on approaches from the fields of statistics and artificial intelligence: information retrieval, machine learning, multicriteria aggregation, reasoning in uncertainty, etc. We aim to output both theoretical results and practical applications. For instance, let us cite ranking comparisons, medical image reconstruction, sentiment analysis and social media mining. Data Mining & Decision (DMD) Team manager : Julien VELCIN
