Increasing Data Complexity: As data kinds like photos, videos, text, and sensor data become more complex, more sophisticated annotation tools are needed to handle a variety of data formats, annotations, and labeling needs. This will spur market adoption and innovation.

Quality and Accuracy Requirements: Training accurate and dependable AI models requires high-quality annotated data. Organizations can attain enhanced annotation accuracy and consistency by utilizing data annotation technologies that come with sophisticated annotation algorithms, quality control measures, and human-in-the-loop capabilities.

Applications Specific to Industries: The development of specialized annotation tools for particular industries, like autonomous vehicles, medical imaging, satellite imagery analysis, and natural language processing, is prompted by their distinct regulatory standards and data annotation requirements.

This dataset contains 35 of 39 taxonomies that were the result of a systematic review. The systematic review was conducted with the goal of identifying taxonomies suitable for semantically annotating research data. A special focus was set on research data from the hybrid societies domain.

The following taxonomies were identified as part of the systematic review:
