You can manually annotate a Corpus, either starting from the beginning or changing the annotations from a previous NER process. To start a process of manual curation from scratch, i.e. when no annotation has been performed, right click on the Corpus datatype and select Corpus -> Manual Curator
A window appears, where you can choose the process name.
When the process ends, a new Process object will be added to the Corpus Process View without any annotations and the user can manually annotate it using the Curator View Annotated Document.
