What is Natural Language Processing (NLP)? - Definition & Meaning
NLP (Natural Language Processing) is a branch of AI that enables computers to understand and generate human language. Learn how NLP works.
Definition
Natural Language Processing (NLP) is a branch of artificial intelligence focused on the interaction between computers and human language. NLP enables machines to read, understand, interpret, and generate text and speech in ways that are useful for applications.
Technical Explanation
NLP encompasses tasks such as tokenization, part-of-speech tagging, named entity recognition (NER), sentiment analysis, machine translation, and text generation. Modern NLP systems are based on transformer architectures (like BERT and GPT) that understand context via self-attention mechanisms. Pre-trained language models are fine-tuned on domain-specific data for better results. Embedding models convert text into numerical vector representations that capture semantic similarities. NLP pipelines combine multiple processing steps to perform complex language tasks.
How Refront Uses This
Refront uses NLP for automatically analyzing ticket descriptions, extracting action items from client communications, and generating summaries of project conversations. The AI agents use NLP to understand the intent behind a client request and take the appropriate action.
Examples
- •NLP analyzes a client email and automatically extracts the requested features as tickets in Refront.
- •Sentiment analysis detects that a client message has an urgent tone, automatically elevating the ticket priority.
- •The AI agent uses NLP to convert a technical ticket description into a comprehensible summary for the client.
Frequently Asked Questions
What is the difference between NLP and NLU?
NLP is the overarching field of language processing. NLU (Natural Language Understanding) is a subfield of NLP that specifically focuses on understanding the meaning and intent behind text, as opposed to NLG (Natural Language Generation) which focuses on generating text.
Which languages does NLP support?
Modern NLP models support dozens of languages, including Dutch and English. Quality varies by language; English typically has the best support due to larger available training data. Multilingual models like mBERT and XLM-R are optimized for cross-lingual tasks.
How accurate is NLP at understanding text?
Modern NLP models perform at human level for many tasks but still struggle with sarcasm, ambiguity, and context-dependent nuances. Accuracy is heavily dependent on the domain and the quality of training data.
