Ludovico Boratto is researcher in the Digital Humanities research department at Eurecat. He previously was a research assistant at the University of Cagliari - Italy. He graduated with full marks and honor and received his PhD in 2012 at the same University. In 2010 and 2014, he spent 10 months at the Yahoo! Lab in Barcelona as a visiting researcher.
His research mainly focuses on recommender systems and data mining in social networks. More specifically, his main research area are group recommender systems that are also able to automatically detect groups of users with similar behaviors (in 2015 a best paper award was assigned to a study on this topic). Another important area that characterized his studies are social recommender systems, in particular those that recommend as friends users that have a similar behavior in the social network (in 2013 a best paper award was given to a work in this area). One of his first recent works on content-based recommender systems has been recognized with another best paper award in 2015.
In 2016 he gave three tutorials on group recommender systems at the ECIR, ECAI, and ACM RecSys conferences.
He is co-author of more than 30 peer-reviewed papers, published in scientific journals, conference proceedings, and book chapters, as well as guest editor of 4 journal’s special issues.

Eloisa Vargiu holds a Ph.D. degree in Electronic and Computer Engineering by the University of Cagliari (Italy). Currently, she is managing the Integrated Continuous Care research line at the eHealth R&D group, EURECAT. She is supervising a work-package in the European projects PEGASO and she is technically coordinating from EURECAT two Spanish projects (myOSA and GERAR).

From January 2012 to June 2015, she was the technical coordinator and main researcher of the EU project “BackHome” (http://www.backhome-fp7.eu/) that was evaluated with “Excellent” by the EC.
During her Ph.D., she studied the pro-active and adaptive behavior of agents and she developed a hierarchical agent architecture. In the same period, she collaborated with the CRS4, an interdisciplinary research center located in Sardinia. During her 4-years post-doc activity, she worked on different projects on bioinformatics and information retrieval. In total, she collaborated more than 10 years with the Intelligent Agents and Soft-Computing (IASC) group at the Department of Electrical and Electronic Engineering (DIEE), of Cagliari.
From 2000 to 2003, she also worked as a tutor in several university courses on fundamentals of computer science and programming languages. From 2003 to 2011, she was a lecturer in several university courses on fundamentals of computer science for students on electronic engineering, computer science, mathematics, letter and philosophy, and cultural heritage.
Finally, she is co-author of more than 50 peer-reviewed publications in international journals and conferences, as well as co-editor of 4 books.
