I'm annotating semantic relations on the NER result created by spans.manual. But when I run the rel.manual recipe, the nested entities will be overlapped by the maximum span. Below is an example.
As you can see, “ranking blog posts” is labeled as “Task” while “blog posts” is labeled as “Material”. But in the relations UI, just “ranking blog posts” is shown as an entity, which prevents me from annotate the relation between “blog posts” and “relevance”.
I have read some discussion about nested spans and learned about solutions such as running multiple passes on the data or encoding entity types with relation labels. These solutions are good, but there are some difficulties for me to implement them. I want to know if there is an easier method to solve this problem.
