# ETD Parsing Train/Test

Metadata records for electronic theses and dissertations, prepared for training and evaluation of metadata-parsing systems. Each JSONL line contains one record.

## Splits

| Split | Records |
| --- | ---: |
| Train | 2,399 |
| Test | 600 |

**The split is held out by degree-granting institution, not random** (revised 2026-09-22; the
previous version of this dataset used a seed-42 random 80/20 split). Grantor strings are
normalized (case, accents, punctuation) and merged when one is a token-prefix of another,
so a single institution never appears in both splits: the test split covers 171 institution
groups and the train split 138, with zero overlap.

The test split contains, in full, the 160-document held-out-grantor evaluation set used for the
`cometadata/etd-metadata-parsing-qwen3.5-4b-dapo` model, plus every additionally annotated
record from those same institutions, plus 108 further institution groups (184 records) drawn at
random (seed 42) from institutions not present in the earlier 1,259-record annotation set. The
eight largest institutions are never held out. Every record that the earlier model was trained
or selected on is in the train split, so test-split scores are comparable to the earlier
held-out results and are not contaminated for that model.

Language distribution (`dc:language`):

| language | train | test |
| --- | ---: | ---: |
| en | 805 | 252 |
| pt | 796 | 61 |
| es | 332 | 84 |
| fr | 243 | 178 |
| de | 98 | 1 |
| nl | 2 | 6 |
| missing | 120 | 17 |

German is concentrated at one institution (Göttingen, among the eight largest), so it is
almost entirely in train; the test split does not measure German performance.

## Fields

Records include filenames (OpenAlex work IDs), identifiers, titles, languages, creators, advisers, degree information, places, and issue dates.
