Data Collection Services

Build high-quality datasets using our expert community.

What is Data Collection?

Data collection is used to create diverse, custom datasets for training machine learning models. However, in order for certain AI algorithms to generalize well, your training data needs to be collected from proper sources, in diverse environments, and free of bias. From images and video to speech data and handwritten text, gathering data requires strict quality protocols, a trained workforce, and a managed platform to store or label the data. 

At Lionbridge, our internal team of data scientists harnesses our global community of 1 million contributors to create the perfect sample group or workforce for your project. After carefully selecting the perfect contributors for your project, we use our data collection and annotation platform to create tailored training data at scale.
