Che cos'è l'elaborazione del linguaggio naturale?
Elaborazione del linguaggio naturale (NLP) è un campo di intelligenza artificiale (AI) che si concentra sull'interazione tra computer e linguaggio umano. Consente alle macchine di comprendere, interpretare e generare il linguaggio umano in modo significativo. La PNL combina la linguistica computazionale con tecniche di apprendimento automatico e di deep learning per analizzare ed elaborare grandi quantità di dati in linguaggio naturale.
Compiti chiave in PNL:
- Classificazione del testo: Categorizzazione del testo in categorie predefinite (ad esempio, rilevamento dello spam).
- Analisi del sentimento: Identificare il sentimento o l'emozione in un testo (ad esempio, positivo, negativo, neutro).
- Riconoscimento di entità denominate (NER): Identificare e classificare entità come nomi, luoghi e organizzazioni.
- Tagging part-of-speech: Determinare il ruolo grammaticale di ogni parola in una frase (ad esempio, nome, verbo).
- Traduzione automatica: Traduzione di testi da una lingua all'altra (ad esempio, Google Translate).
- Riconoscimento vocale: Conversione del linguaggio parlato in testo (ad esempio, applicazioni voice-to-text).
- Riassunto del testo: Creare un riassunto conciso di un testo più ampio.
- Risposta alle domande: Trovare risposte a domande poste in linguaggio naturale (ad esempio, motori di ricerca).
Applicazioni della PNL:
- Chatbot e assistenti virtuali (ad esempio, Siri, Alexa).
- Analisi del sentimento per il monitoraggio dei social media.
- Traduzione linguistica per le comunicazioni multilingue.
- Estrazione del testo per estrarre informazioni preziose da grandi insiemi di dati.
- Riconoscimento vocale per le applicazioni a controllo vocale.
