What is Data Annotation?
Data annotation is the process of labelling or tagging labels to the raw inputs — such as text, audio, video, images, or last but not least sensor data, which are collected from the IoT devices — which enables your AI algorithms to interpret information, learn and make decisions. Accurate annotations turn real-world complexity into model-ready formats, enabling your AI to:
Precisely detect and classify objects in images.
Extract sentiment, intent, and entities from text.
Transcribe and timestamp speech for natural dialogue.
Recognize actions and events across video sequences.
Types of Data Annotation
As a top data annotation company in Toronto, we, Macgence, leverage rigorous quality controls and domain expertise to ensure every dataset—whether text, video, images, sensor data, or audio — meets the highest standards of accuracy and reliability. We have the right solution for you and your AI innovation.

Text Annotation
Text annotation enables your machine learning or deep learning algorithms to comprehend and interpret human language by labelling elements like words, phrases, and sentences. Our text-level labels power your chatbots, sentiment analysis, document automation, and intelligent search. At Macgence, in Text Annotation, we offer a total of over 10+ annotations, including some of the key ones listed below:
Named Entity Recognition
Recognize individuals, organizations, dates, and places.
