TLDR:
NLP is a branch of artificial intelligence that enables computers to understand, interpret, and generate human language, powering applications like chatbots, translation, sentiment analysis, and search.
Core NLP Tasks
NLP encompasses many tasks: tokenization (splitting text into words/subwords), part-of-speech tagging, named entity recognition (identifying people, places, organizations), sentiment analysis, machine translation, summarization, question answering, and text generation. Modern transformer-based models (BERT, GPT, T5, LLaMA) achieve state-of-the-art results across most of these tasks through pre-training on massive text corpora.
Business Applications
NLP powers numerous business applications including customer service chatbots, contract analysis and review, compliance monitoring, content moderation, search relevance, voice assistants, automated email triage, and document intelligence. The rise of large language models has dramatically expanded what’s possible — startups can now build sophisticated NLP applications by fine-tuning or prompting foundation models rather than training from scratch.
Legal and Ethical Considerations
NLP applications raise important issues including bias in language models (reflecting biases in training data), privacy concerns when processing personal communications, copyright questions around training data and outputs, regulatory requirements like GDPR for processing personal data in multiple languages, and accuracy concerns in high-stakes applications like legal or medical advice. Responsible NLP deployment requires human oversight, transparency, and clear use case boundaries.

NLP products and their data
NLP systems are personal-data machines whenever the text concerns people — support tickets, emails, call transcripts — so the engineering pipeline needs KVKK/GDPR plumbing: lawful bases for training versus inference, retention rules for raw text, and pseudonymisation that actually resists re-identification in free text (names are the easy part; context is the leak). Sector overlays bite: health-related text triggers special-category rules; recorded calls have their own consent regimes. Contract-side, training rights over customer text are never implied — agreements should state whether de-identified usage data may improve models, and enterprise buyers increasingly demand a no-training default. The reliable design: data flows mapped per use case before the model card is written.
