Data collection is the process of gathering secondary or newly generated data to use in projects such as AI development, market research, educational research, etc.
Data collection companies offer different types of data, either by generating it or gathering it from various sources. Their offerings include AI training datasets, market research datasets, academic research datasets, survey data, etc.
