High-quality text data to train generative AI, ASR systems, search engines and more

Text annotation for AI

Text annotation is the process of creating metadata in the form of labels for text data by tagging keywords, phrases, and sentences so that machine learning models can understand and communicate with humans using natural language.

Text annotation is used to train NLP algorithms used in chatbots, automated speech recognition (ASR) systems, search engines, generative AI applications, and more. It is also used to automate document reviews and to extract insights from large databases of information. To ensure accuracy, it is critical to work with native speakers so that the AI solution will work effectively in each target market.
