Doccano in AI answers

Doccano is an open-source data labeling tool for machine learning practitioners that supports various labeling tasks and data formats, and can be used via a demo or integrated with scripts through its REST APIs. It guides users through a labeling workflow—from installing and running doccano, creating labeling projects, importing datasets, defining annotation guidelines, labeling data, to exporting the labeled datasets. The system uses a Django-based backend with a Vue.js/Nuxt frontend, exposing REST APIs and a web interface, with options for cloud storage, authentication, and advanced settings.
