A suggestion how we could support pickle and deepcopy without having to create multiple spans etc.
The idea is to use
__getitem__
to create spans and relations by indexing:sentence[0:5]
to create a span,sentence[span_a, span_b]
to create a relation.Downside would be, that those who still instantiate
Span
orRelation
manually, would receive unexpected results.@dobbersc @alanakbik what do you think?
