What We Think

Frequently Asked Questions

Data annotation is the process of labeling data (text, images, audio, etc.) with relevant information. This labelled data is crucial for training AI models. It helps the AI “understand” the data and learn to identify patterns and relationships. Without annotated data, AI models wouldn’t be able to perform tasks like recognizing objects in images, translating languages, or understanding human speech.

Practically any kind of data can be annotated!

Here are some common examples:

  • Images: Labeling objects, scenes, or activities in pictures. (e.g., a car, a traffic light, a busy intersection)
  • Text: Categorizing sentiment (positive, negative, neutral), identifying entities (people, locations, organizations), or extracting specific information (dates, names, product details).
  • Audio: Transcribing speech, classifying emotions (happy, angry, sad), or identifying background noise.
  • Video: Labeling objects and actions in video footage, tracking movement, or creating 3D models.

Data annotation is typically performed by human annotators who follow specific guidelines. There are also specialized annotation tools available to streamline the process.

While AI can be used to assist with some aspects of data annotation,
it’s not yet reliable enough to do it entirely on its own. Human expertise is still essential for ensuring accuracy and consistency in the annotations.

Many companies offer data annotation services. Look for those with experience in your specific industry and data type. They should be able to provide high-quality, accurate annotations that meet your project requirements.
