About us

Since 2016, Datamundi has been creating and enriching language data for linguistic research institutes and global NLP system builders. Our focus is on text annotation for machine translation and LLMs, but we also can do voice, video and image labelling.

To meet our customer needs we created an “intelligent” portal where we give clear job instructions to more than a thousand linguists and annotators doing the specialist, hands-on work. This way we help on each step of the NLP production chain: data discovery and collection, text selection and cleaning, test set creation and validation,  annotation, labeling, tagging data for ML training and testing.

Carefully recruited and trained, our linguists work solely online on the Datamundi platform, which guarantees clients the highest possible level of confidentiality and security. Datamundi undertakes an ongoing process of quality control of all the work being carried out in more than one hundred countries. Being extremely flexible, the portal can accommodate varied types of projects, tweaking the interface as per the client needs.

Our PMs and developers work closely with our customers’ scientists and A.I. engineers, making sure their needs are correctly transformed into tasks and instructions for the annotators, therefore customers place trust in our service and rely on our consultancy.
