FAQ

Why is annotation crucial for data?

Data analysis and annotation are essential to model performance as these technologies transform raw, unstructured data into a format that AI and ML models can comprehend. Without proper annotation, AI systems are prone to bias and can’t recognize patterns, classify information, or make accurate predictions for data-driven decisions.

What are the key challenges in data annotation?

Inconsistencies and bias caused by human errors, high cost of manual labeling, and scalability issues of large datasets all pose challenges to further solution development. However, choosing a reputable data annotation services company helps businesses mitigate those issues and increase efficiency of their operations.

How is data annotation performed?

The process starts with data collection, sometimes followed by data augmentation and then data preprocessing, which helps clean and format the information for a complete quality dataset. Annotators often use specialized tools to label existing data, either manually or with AI. After that, quality control is held to ensure accuracy and consistency before starting the AI training.

How is data annotation different from data labeling?

Annotation is a broader term that means adding segmentation, metadata, or any kind of descriptive information to data. On the other hand, data labeling is a specific type of annotation conducted by assigning data with predefined tags or categories, e.g. labeling images as “dog” or “cat.”
