In questo blog esploreremo il I 10 principali strumenti e piattaforme di PNL che può trasformare il modo in cui le aziende elaborano e analizzano i dati linguistici.

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:

1. Classificazione del testo: Categorizzazione del testo in categorie predefinite (ad esempio, rilevamento dello spam).
2. Analisi del sentimento: Identificare il sentimento o l'emozione in un testo (ad esempio, positivo, negativo, neutro).
3. Riconoscimento di entità denominate (NER): Identificare e classificare entità come nomi, luoghi e organizzazioni.
4. Tagging part-of-speech: Determinare il ruolo grammaticale di ogni parola in una frase (ad esempio, nome, verbo).
5. Traduzione automatica: Traduzione di testi da una lingua all'altra (ad esempio, Google Translate).
6. Riconoscimento vocale: Conversione del linguaggio parlato in testo (ad esempio, applicazioni voice-to-text).
7. Riassunto del testo: Creare un riassunto conciso di un testo più ampio.
8. 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.
