* Support a cfg field in transition system * Make NER 'has gold' check use right alignment for span * Pass 'negative_samples_key' property into NER transition system * Add field for negative samples to NER transition system * Check neg_key in NER has_gold * Support negative examples in NER oracle * Test for negative examples in NER * Fix name of config variable in NER * Remove vestiges of old-style partial annotation * Remove obsolete tests * Add comment noting lack of support for negative samples in parser * Additions to "neg examples" PR (#8201) * add custom error and test for deprecated format * add test for unlearning an entity * add break also for Begin's cost * add negative_samples_key property on Parser * rename * extend docs & fix some older docs issues * add subclass constructors, clean up tests, fix docs * add flaky test with ValueError if gold parse was not found * remove ValueError if n_gold == 0 * fix docstring * Hack in environment variables to try out training * Remove hack * Remove NER hack, and support 'negative O' samples * Fix O oracle * Fix transition parser * Remove 'not O' from oracle * Fix NER oracle * check for spans in both gold.ents and gold.spans and raise if so, to prevent memory access violation * use set instead of list in consistency check Co-authored-by: svlandeg <sofie.vanlandeghem@gmail.com> Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com>
