BRATenabled

BRATenabled is a software tool designed to facilitate the creation and analysis of annotated text data. It is based on the popular BRAT (Brat Rapid Annotation Tool) system, which is widely used in natural language processing (NLP) research for tasks such as named entity recognition, relation extraction, and event annotation. BRATenabled aims to streamline the annotation process by providing a user-friendly interface and robust backend functionality.

The core of BRATenabled is its web-based annotation interface. Users can upload documents, define custom annotation types, and then manually highlight and label spans of text. The tool supports the annotation of entities, attributes, and relations between entities. A key feature is the ability to collaborate on annotation projects, allowing multiple annotators to work on the same dataset simultaneously and facilitating consistency checks.

Beyond annotation, BRATenabled offers features for managing annotation projects. This includes version control for annotations, the ability to export annotated data in various formats compatible with common NLP libraries, and tools for analyzing annotation quality and inter-annotator agreement. The software is typically deployed on a server, making it accessible to research teams without requiring individual installations of the annotation software on each annotator's machine. Its open-source nature has contributed to its adoption in academic and research settings for developing and evaluating NLP models.
