  1. DATA ANNOTATION • VS. • DATA COLLECTION Understanding the Key Differences info@damcogroup.com www.damcogroup.com

  2. INTRODUCTION • Explore the key differences between data collection and data annotation to better understand their roles in building AI and ML systems.

  3. WHAT IS DATA COLLECTION? • Definition: • Data collection is the process of gathering raw information from various sources for analysis or use in AI/ML models. • Sources: • Surveys and forms • Web scraping • Sensors and IoT devices • APIs and databases • Purpose: • To obtain relevant, high-quality, and diverse data sets for further processing.

  4. WHAT IS DATA ANNOTATION? • Definition: • Data annotation involves labeling or tagging raw data to make it understandable for machines. • Types of Annotation: • Image Annotation • Text Annotation • Audio Annotation • Video Annotation • Purpose: • To train AI/ML models by providing context and meaning to the data.

  5. KEY DIFFERENCES – OVERVIEW TABLE

  6. REAL-LIFE EXAMPLES

  7. IMPORTANCE IN AI/ML WORKFLOW • Data Collection provides the fuel (raw data) • Data Annotation shapes that fuel for specific tasks • Both are critical, but serve different purposes • Incorrect annotation = biased or poor model performance

  8. USE CASES BY INDUSTRY

  9. CONCLUSION • Data collection gathers the raw input; data annotation adds meaning. Both are essential, distinct steps in creating reliable AI solutions.
