A Sentence within the corpus that was subject to annotation. B Sentence annotation result visualized with TextAE. Annotation tool based on TextAE: TextAE is a text annotation tool that can annotate named entity and relation information in the text. Each term (entity) can be dragged or double-clicked in Term Edit Mode, and the corresponding type can be selected to annotate them. If the corresponding entity type does not exist at the time, a new type can be defined. Likewise, in Relation Edit Mode, a type of relation can be selected or created and visualized. It is also possible to annotate multiple relations where one entity is associated with multiple other entities at once. The results of the annotation can be downloaded locally in the form of a json file
