Kili Technology provides a annotation interface for named entities recognition (NERs) and annotation of relationships between entities to perform the most common NER annotation tasks.
Once the list of entities has been configured, the annotation is simple. Selecting the text displays the list of entities, which you just have to click on. Or you can use shortcuts (underlined letters).
Select the type of relations, click on "Link Entities", and simply click on the entities you want to link. When the relationship is built, to click "Stop Linking".
Relations are directionals. The relation configurator allows to build any type of relationships.
