Data Annotation in Practice

Data annotation is the process of labeling data to make it understandable for machines. It is the critical first step in training robust AI models. Here's a look at the types of annotation I specialize in:

Image Annotation

Adding metadata to images to train computer vision models.

  • Bounding Boxes: Drawing rectangles around objects to detect and locate them.
  • Semantic Segmentation: Pixel-level labeling to understand the scene context.
  • Landmark Annotation: Marking key points on objects (e.g., facial features).
Bounding Box Annotation Example Semantic Segmentation Example Analytic Segmentation Example

Text Annotation

Labeling text data to train NLP models for understanding language.

  • Named Entity Recognition (NER): Identifying and tagging real-world objects like persons, organizations, and locations.
  • Sentiment Analysis: Labeling text as positive, negative, or neutral.
  • Intent Classification: Categorizing text based on the user's intent (e.g., request, complaint).
