"Numero articoli" is "number of papers", "Numero citazioni" is "number of citations", and "Indice H" is "h-index". The thresholds are different for each research area (e.g., "INFORMATICA" is "computer science").
The topic is actually a little bit more complex, since looking at the metrics is only one step of the process.
