Was ist Verarbeitung natürlicher Sprache?
Natürliche Sprachverarbeitung (NLP) is a subfield of artificial intelligence (AI) that focuses on the interaction between computers and humans through natürliche Sprache. The goal of NLP is to enable machines to understand, interpret, and generate human language in a way that is both meaningful and useful.
NLP umfasst mehrere Schlüsselaufgaben, darunter:
- Tokenisierung: Breaking down text into smaller units, such as words or phrases, to analyze linguistic structure.
- Part-of-Speech-Tagging: Identifying the grammatical categories of words, such as nouns, verbs, and adjectives, to understand their roles in sentences.

- Sentiment-Analyse: Assessing the emotional tone of a piece of text to determine whether it is positive, negative, or neutral.
- Maschinelle Übersetzung: Automatically translating text from one language to another while preserving meaning.
NLP verwendet verschiedene Techniken aus der Linguistik, Informatik, and machine learning. Traditional methods involve rule-based systems and grammar, while modern approaches often leverage deep learning models, such as neural networks, to improve accuracy and performance.
Applications of NLP are widespread and include virtual assistants (like Siri and Alexa), chatbots for customer service, der Sprachübersetzung services, and tools for analyzing social media sentiment. As NLP continues to advance, it is reshaping how we interact with technology, making it more intuitive and responsive to our natural communication.
