Frequently Asked Questions
What is text annotation, and why is it critical for Generative AI?
Text annotation structures raw language data by adding labels, tags, and metadata, enabling models to understand meaning, context, and intent. High-quality annotation is essential for training, fine-tuning, and evaluating reliable GenAI systems.
What types of text annotation does DDD provide?
DDD supports a wide range of NLP tasks, including named entity recognition, text classification, sentiment analysis, intent detection, semantic similarity, summarization, content moderation, and multilingual annotation.
How does DDD ensure annotation quality and consistency?
We apply multi-layer quality control, including trained annotators, inter-annotator agreement checks, expert validation, and continuous feedback loops.
Can you annotate multilingual and low-resource languages?
Yes. DDD provides native-speaker annotation across global languages, including low-resource and region-specific dialects.
