To create a new entity, first select any segment of text in the text view (on the left). With a mouse (or other point device), drag the selection onto the top most node in the tree on the right. If you drop the selection, a new entity will be created, with a single mention. The entity now appears in the tree with a specific color, and the text segment you marked in the text is now underlined with the same color. The name of the entity will be the same as the text segment. Both name and color can be changed at any time.
CorefAnnotator can be used by keyboard. To annotate, mark a text segment
using SHIFT
and the RIGHT ARROW
key. When you're done
with text highlighting, press TAB
once to jump to the search field
on top of the tree view. In the search field, you may enter words, substrings
or even regular expressions, to search among all entity labels and mention
surfaces. All matching entities will be sorted to the top of the tree. Using
ARROW DOWN
you can then select an entity in the tree. To annotate,
press ENTER
while the correct entity is selected.
Each entity can be assigned a single letter shortcut. This is done via the edit menu or by right-clicking on an entity. When text is selected, a single key can be pressed to assign the mention to an existing entity.
If a text string is selected, clicking the right mouse button (or pressing the space bar on the keyboard) shows a context menu that contains candidates. The candidates are based on the previous mentions as well as textual overlap with the mentions of any other entities.
