What is Crowdsourcing?

Crowdsourcing is the process of harnessing the intelligence, skills, cultural knowledge, or data from a large group of people to provide one collaborative service. Lionbridge specializes in crowdsourcing for mass translation projects, AI training data production, ad evaluation, search evaluation, and more.

Utilize Lionbridge’s large and vetted crowd to create focus groups for surveys, collect and produce training data for machine learning, review advertisements, and scale localization projects. Our SmartCrowdTM includes multilingual workers from all backgrounds and all walks of life. We can source non-specialized workers for basic annotation tasks, or provide field experts with in-depth knowledge in linguistics, niche languages, medical fields, and other specializations.

Crowdsourcing allows you to reduce costs, offload tedious tasks, and scale-up your services. Recent advancements in technology allow businesses to crowdsource larger pools of staff than ever before.
