Data Annotation

Enrich your data with our range of human-annotation services at scale.

It’s simply not enough to give a computer a large amount of data and expect it to learn – data has to undergo preparation for computers to find patterns and inferences within it. That’s where we come in. We preprocess data to make it usable for machine learning. “Annotation” refers to any metadata tag used to mark up elements of a dataset. Adding meaningful metadata to the original dataset provides a layer of rich information to support machine learning.

Data annotation and labeling services

Our extensive data annotation services, alongside our global AI Community, will improve your machine learning models to create better AI systems.

Data classification services

Using human annotators, we can quickly classify your data into predetermined categories across any data type. Notably, this includes audio / sound classification to support NLP applications like chatbots, automatic speech recognition, text-to-speech and more, as well as text classification to analyze and tag content while understanding the subject, recognizing the intent, and analyzing the sentiment within it.

Transcription services

Available across multiple data types, our transcription services drive more value from your existing data. For example, our team can digitize text that is pictured in an image such as a photo of a receipt or handwriting. This then supports optical character recognition (OCR) models. Likewise, our video transcription services convert what is spoken on video into written text for subtitling or captioning. This makes online videos more searchable and accessible because it provides a better UX and boosts SEO.

Entity annotation and linking services

A named entity embodies a single distinct concept, often with a proper name, like “Japan” or “Elvis Presley”. However, the number of ways to classify entities is almost endless. We’ve spent years building solutions that can locate and label entities in raw text data. Likewise, entity linking involves locating and disambiguating named entities in a text through the use of a knowledge base. The purpose of entity linking is to add metadata that not only identifies the appearance of a named entity in the text, but also which specific entity it is.

Tying entities to a unique entry in a knowledge base is an important step in the construction of many machine learning text algorithms.

Sentiment analysis services

Also known as opinion mining or emotion AI, sentiment analysis determines whether a text is positive, negative or neutral by extracting particular words or phrases. Sentiment analysis provides helpful insights that drive effective business strategy. Language is often vague or highly contextual, making it very difficult for a machine to understand without human help. As such, human annotated data is essential when training a machine learning platform to analyze sentiment.

Success stories

Data annotation improves conversational chatbots

Even today, chatbots used for customer service often lack a human touch. Why? Because the unstructured nature of conversation is particularly difficult for machine learning. Our client wanted a conversational bot to engage its users. This required finding a partner that could deliver a wide range of text data reflective of natural conversation and accurately labeled for emotional intent. TELUS International was selected to create this AI training data. The results:

  • 5,000+ Q&A text sample
  • Each set labeled for emotional intent
