Adriane Boyd a4b32b9552 Handle missing reference values in scorer (#6286) ... * Handle missing reference values in scorer Handle missing values in reference doc during scoring where it is possible to detect an unset state for the attribute. If no reference docs contain annotation, `None` is returned instead of a score. `spacy evaluate` displays `-` for missing scores and the missing scores are saved as `None`/`null` in the metrics. Attributes without unset states: * `token.head`: relies on `token.dep` to recognize unset values * `doc.cats`: unable to handle missing annotation Additional changes: * add optional `has_annotation` check to `score_scans` to replace `doc.sents` hack * update `score_token_attr_per_feat` to handle missing and empty morph representations * fix bug in `Doc.has_annotation` for normalization of `IS_SENT_START` vs. `SENT_START` * Fix import * Update return types		2020-11-03 15:47:18 +01:00
