Text Annotation
Our text labeling services handle a vast range of scripts and languages, ensuring seamless integration for natural language processing, document processing, chatbots, transcripts and more. We offer a suite of powerful features, including classification, named entity recognition, keyphrase extraction, intent classification, question answering, sentiment analysis and text summarization.

Data labeling can be expensive, slow and labor-intensive, but it's necessary to derive value from AI/ML models using unstructured data, such as text, images, videos and audio data. New AI-assisted software platforms, such as TELUS Digital Ground Truth Studio, dramatically reduce the effort traditionally required by human labelers, resulting in reduced time and costs for data labeling while delivering improved quality and accuracy of results.
