# CM-Annotator Parallel Annotation Corpus (annotation layer)

English-Chinese parallel sentence pairs from UM-Corpus (Tian et al., LREC 2014; CC BY-NC-ND 4.0)
with conceptual-metaphor span annotations (English and Chinese) and pair-level translation
relations (PRESERVE / REPLACE / LITERALIZE / DELETE / ADD / NONE).

**This is the annotation layer only: `pair_id` + annotations. Sentence text is NOT included**
(UM-Corpus license prohibits redistribution). Restore full text with `scripts/rebuild_fulltext.py`
from your own copy of UM-Corpus. See docs/DATA_CARD.md in the code repository.

## Stats

- pairs: 5000
- EN spans: 3631 / ZH spans: 1652
- null-CM rate: EN 0.686, ZH 0.837
- relations: {'REPLACE': 544, 'DELETE': 808, 'NONE': 3299, 'PRESERVE': 141, 'LITERALIZE': 78, 'ADD': 130}

## Schema

`pair_id`, `domain`, `en_annotation{has_metaphor, metaphor_spans[]}`,
`zh_annotation`, `pair_relation{rel_primary, relations[], links[]}`.
Spans: text/position are omitted in this layer except span metadata (cm_id, cm_name,
source_family, macro_class, conventionality) — see DATA_CARD for the full schema and
provenance. Annotations are model-generated silver labels distilled with human auditing;
they are NOT gold-standard human annotations.
