Ríssola, Esteban A. ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO009.

Language use acts as an indicator of the individuals’ current mental state, personality and even personal values. In this thesis, we focus on language analysis to study two closely related processes which encompass integral components of...

Khayati, Mourad ; Arous, Ines ; Tymchenko, Zakhar ; Cudré-Mauroux, Philippe

In: Proceedings of the VLDB Endowment, 2020, vol. 14, no. 3, p. 294-306

With the emergence of the Internet of Things (IoT), time series streams have become ubiquitous in our daily life. Recording such data is rarely a perfect process, as sensor failures frequently occur, yielding occasional blocks of data that go missing in multiple time series. These missing blocks do not only affect real-time monitoring but also compromise the quality of online data analyses....

The coffee industry and particularly coffee producers are facing difficult and challenging times. For years coffee prices have been falling and therefore producers have seen their revenue shrinking. This situation can be somewhat counterintuitive for French-speaking Swiss coffee consumers who have seen the selling price of their caffeine intake increase over time. However, the drop in coffee...
