Data Science
Cluster
- Big Data Analytics and Information Systems
Description
The group deals with several research themes that can be summed up as follows:
- The analysis and visualisation of networks. The approach aims to integrate mathematical aspects of a formal type with the experimentation on instances taken from the world of real networks.
- The use of data analytics techniques for assessing the effectiveness of information retrieval systems.
- The design, development and implementation of compression algorithms and data structures. In particular, the development of online algorithms for analysing and researching in strings and in graphs. Indexing and compression.
- The use of machine learning algorithms for classification (categorial data) and the regression (numerical data), with particular interest being paid to mining and sequence analysis.
- The use of multi-objective optimisation techniques through genetic algorithms in the domain of data mining.
Research subjects
- Rating and ranking metrics in the sports context, with possible applications to bibliometric networks.
- valutazione, ingegnerizzata ed efficiente, dell'efficacia dell'information retrieval, al fine di risparmiare risorse senza limitare l'affidabilità della valutazione
- Study and definition of new effectiveness metrics, and formalisation of the properties of existing metrics.
- Crowdsourcing (outsourcing to non-structured and non-organised masses) for the retrieval of relevance judgements.
- algoritmi e strutture dati per la rappresentazione di collezioni di stringhe mediante string-graphs e loro evoluzioni. Compressione e ri-compressione di stringhe, collezioni di stringhe, grafi. Rappresentazioni numeriche
- definizione, implementazione e verifica formale di algoritmi di data mining che garantiscano la privacy differenziale. Studio di meccanismi che garantiscano la protezione dei dati in un contesto distribuito
- Design of decision support systems, in the context of contact centres, with advanced functionalities for data mining and data analytics.
