Riassunto
“Cosa ne pensano gli altri?” è da sempre la domanda fondamentale di chi ha l’onere di prendere decisioni o vuole capire quali siano stati gli effetti delle decisioni stesse o ancora di chi è interessato a conoscere a fini di studio (o di semplice curiosità). Per la quantità di testi digitali che se ne possono estrarre una miniera inesauribile di opinioni è sicuramente la rete, come abbiamo visto nel Cap. 1. Ma ancora prima dell’esplosione del WWW e dei social media, linguisti assieme a statistici ed esperti di computer science hanno riadattato vecchie tecniche e ne hanno sviluppate di nuove per cercare di estrarre il sentiment e le opinioni dai testi digitali.Come in ogni ambito, ogni tecnica ha i suoi pro e contro e di fatto non esiste “la tecnica migliore” o quella universale, anche se si pò discriminare sicuramente quella che ad oggi ha garantito il più alto numero di successi rispetto ad altre. Quindi parafrasando Oscar Wilde: il sentiment non è il punto di partenza ma quello di arrivo.
Romance should never begin with sentiment. It should begin with science and end with a settlement OscarWilde, An Ideal Husband
