Key Tasks in NLP:
- Text Analysis: Extracting information from written text by identifying key topics or sentiments.
- Speech Recognition: Converting spoken language into text.
- Machine Translation: Translating text from one language to another, like translating English to Spanish.
- Sentiment Analysis: Analyzing the emotional tone of a text (positive, negative, or neutral).
- Named Entity Recognition (NER): Identifying and categorizing key elements in a text such as names, organizations, and locations.
- Text Generation: Generating new coherent text based on a given input, such as generating chatbot responses.
- Language Modeling: Predicting the next word in a sentence, useful for applications like autocomplete.
