Data Annotation of Invoices

Client Overview

Our client is a Japanese Company who is employing digital transformation. To be more specific, they need to annotate handwritings in invoices (both includes letters and numbers) into digital data.

Specific Requirement

The data inputs are invoices with handwritings on it. The client wants those handwrtings to be annotated in the form of digital data such as digits and words. The words are mostly in Japanese.


With the texts in the invoices mostly in Japanese, LQA set up a team that can understand and handle Japanese Texts. These texts are often quite hard to understand (as they are handwritings).
