OpenGloss v2.1 — Relations

The OpenGloss v2.1 semantic graph as an edge list. The relations config holds every live typed edge — fourteen relation types — with the target resolved to a sense id wherever the target's entry exists in the release, which is what makes this a sense graph rather than a word graph. The tombstoned config recovers the edges the free reconcile pass demoted, deduplicated or capped away, with the type they carried when they were removed and the reason recorded on them, reconstructed from the provenance trail rather than kept in a side table (D-65, D-68).

Part of the OpenGloss v2.1 release family — 16 datasets built from one store of 109,633 lexemes and 250,003 live senses, all joinable on derived ids. See Related datasets for the rest.

What's new in v2.1 vs v1.3

1. Schema v3. Every lexeme carries a kind discriminator (simplex, compound, phrasal verb, idiom, proper noun, abbreviation, affix, function word); every sense carries a controlled domain leaf from a fixed ~160-leaf taxonomy instead of free text; every example carries the character span of the headword occurrence inside it.
2. Renditions, not one string. A definition is a set: the canonical one plus rewrites at four reading levels and in four registers, each produced in a single call from the canonical text so they say the same thing at different altitudes.
3. A sense graph, not a word graph. Typed relations resolve to sense ids wherever the target's entry exists in the release, so bank --hypernym--> financial institution points at a meaning rather than at a string.
4. Retrieval data is first-class. Synthetic per-sense queries in eight styles, grounded QA pairs, mined word-in-context pairs, MS MARCO-style triples with graph-derived hard negatives, and graded TREC qrels — all derivable from, and consistent with, the same entries.
5. Derivable identifiers everywhere. v1.3 published a positional id for lexemes and senses (3d_model_noun_0) and nothing below that. v2.1 gives every rendition, edge, query, QA pair and provenance record an id computable from the row alone, and never renumbers: a retired sense is tombstoned, so the ids after it keep their meaning.
6. Per-field provenance. Which model wrote a field, how many tokens it took, what it cost — published as its own dataset.

What changed since v2.0

v2.0 (2026-09-05) covered the frequency-ranked single words. v2.1 adds tier 4: the function words the core ranking had excluded on purpose, and every remaining v1.3 entry at Wikipedia frequency ≥ 10 — mostly multiword compounds ("natural selection", "catalog number"), plus names and rarer single words. That doubles the lexeme count and changes the mix: v2.0 was 99.8% single words; a third of v2.1 is multiword.

Schema. No column was added, removed or retyped in any existing dataset. Three things did change:

• tier gains the value tier4 (it was core, tier2 or tier3).
• One new dataset, opengloss-v2.1-inflections: a flat surface-form → lemma lookup (plural, past tense, participles, comparative, superlative, derivations) built from the morphology that the lexicon already carried nested.
• New provenance note prefixes on tombstones and edges, all reversible and all counted in the store audit: phantom_pos: (a v1.3 part-of-speech block whose glosses defined a component word rather than the compound — 11,440 blocks retired), regen: (relations regenerated for senses that had lost every edge to judging), and retyped: contrast (synonym edges the contrast paragraphs showed to be hypernym or hyponym).

Not row-compatible with v2.0. Lexeme, sense, rendition, edge, query and QA ids are stable for every entry v2.0 had. The derived training sets (retrieval-pairs, retrieval-triples, qrels) re-sample negatives over the larger pool, so their rows differ; and the store-wide quality passes run for v2.1 retired ~3,000 senses of the v2.0 entries (phantom part-of-speech blocks and near-duplicate senses), so those senses are now tombstoned rather than live. Treat v2.1 as a new release, not a delta.

Scope: fewer headwords, far more per headword

v2.1 is not a superset of v1.3. It covers 109,633 of v1.3's 205,988 lexemes — every frequency-ranked single word, plus the compounds and names at Wikipedia frequency ≥ 10 — and spends the difference on depth. If you need breadth of vocabulary, use v1.3; if you need graded renditions, resolved relations, spans, or retrieval supervision, use v2.1.

Senses	565,604	250,003
Definition renditions per sense	1 canonical	1 canonical + up to 8 graded

Coverage by tier

The release was built in 4 frequency-ranked passes (core, tier2, tier3 and tier4) and they did not all receive the same stages. This table is per-field and per-tier so the gaps are visible rather than averaged away.

Fields

Config relations

1,574,438 rows, one row per live relation edge.

Field	Type	Description
edge_id	string	Derived edge id: {source_sense_id}-{type}->{target_lexeme_id}. Stable across resolution, because it keys on the target's slug, not its sense.
source_sense_id	string	The sense asserting the relation.
source_lexeme_id	string	That sense's entry id.
headword	string	That entry's headword.
pos	string	Part of speech of the source sense.
type	string	One of synonym, antonym, hypernym, hyponym, meronym, holonym, derivation, collocation, confusable_with, see_also, causes, entails, used_with, instance_of.
target_term	string	The target's surface form, as written.
target_lexeme_id	string	slugify(target_term) — always derivable.
target_sense_id	string	The resolved target sense, or null when the target's entry is not in the release.
resolved	bool	Whether target_sense_id is non-null.
confidence	double	The resolver's confidence, 0–1, when resolved.
note	string	Free text on the edge. Required on confusable_with (how the two differ); elsewhere it carries a hygiene pass's reason.
tier	string	Tier of the source entry.

One real row:

{
  "edge_id": "a:determiner:0-synonym->one",
  "source_sense_id": "a:determiner:0",
  "source_lexeme_id": "a",
  "headword": "a",
  "pos": "determiner",
  "type": "synonym",
  "target_term": "one",
  "target_lexeme_id": "one",
  "target_sense_id": "one:determiner:0",
  "resolved": true,
  "confidence": 0.9,
  "note": null,
  "tier": "tier4"
}

Config tombstoned

2,223,138 rows, one row per removed relation edge.

Field	Type	Description
edge_id	string	The removed edge's id, reconstructed from the record.
source_sense_id	string	The sense the edge was removed from.
source_lexeme_id	string	That sense's entry id.
headword	string	That entry's headword.
type	string	The type the edge carried when it was removed — which is what its id is built from. The pre-demotion type is only recoverable when the reason names it (retyped: nano synonym→see_also).
target_term	string	The target's surface form.
target_lexeme_id	string	slugify(target_term).
step	string	Which reconcile step removed it: tombstone (a demoted edge), dedup (an exact duplicate) or cap (per-type overflow).
reason	string	The note the edge carried when it was removed — the demotion reason, or - where it had none (usual for cap).
provenance_id	string	The entry provenance record this was read from.
tier	string	Tier of the source entry.

One real row:

{
  "edge_id": "a:determiner:0-see_also->any_one",
  "source_sense_id": "a:determiner:0",
  "type": "see_also",
  "target_term": "any one",

  "source_lexeme_id": "a",
  "headword": "a",
  "provenance_id": "p28",
  "tier": "tier4"

print(df.head())

graph.add_edges_from(edges.select("source_sense_id", "target_sense_id").rows())
print(graph.number_of_nodes(), "senses,", graph.number_of_edges(), "hypernym edges")

Identifiers, and how they compose

Every id is derived from structure, never randomly minted, so a consumer can recompute one from a row and join across the whole family without a lookup table. Sense positions are stable across regenerations: a retired sense is tombstoned, not removed, so the indices after it never shift.

Id	Shape	Example
Lexeme	slugify(headword)	abseil
Sense	{lexeme_id}:{pos}:{index} (zero-based)	abseil:verb:0
Rendition	{owner_id}#{reading_level}/{register}	abseil:verb:0#grade_5/plain
Entry-level owner	{lexeme_id}:encyclopedia / :explanation	abseil:encyclopedia
Edge	{source_sense_id}-{type}->{target_lexeme_id}	abseil:verb:0-synonym->rappel
Query	{sense_id}#q{n} (zero-based)	abseil:verb:0#q3
QA pair	{sense_id}#qa{n} (zero-based)	abseil:verb:0#qa3
Provenance record	p{n} within its entry (one-based)	p12

An edge id keys on the target's slug, not on the target's sense, so resolving a target never changes the id of the edge that found it.

Reading levels and registers

A rendition is keyed on a (reading_level, register) pair. The canonical rendition of every field is (neutral, plain); everything else is a rewrite of it.

reading_level	Who it is written for	Rough CCSS band
neutral	The canonical text: an adult general reader, no level targeted	—
grade_1	Beginning readers; short sentences, common words	K–1
grade_5	Upper elementary	4–5
grade_10	Secondary	9–10
college	Undergraduate and above; technical vocabulary allowed	11–CCR

register	What changes	Reading it
plain	Nothing — the neutral register	The default
informal	Conversational, contractions, everyday words	How you'd say it to a friend
formal	Full forms, precise hedging, no contractions	How you'd write it in a report
technical	Domain vocabulary, exact conditions	How a specialist would state it
marketing	Benefit-first, persuasive framing	A genre, not a formality level

marketing sits on the register axis for convenience but is a genre value rather than a point on the formality scale — worth remembering if you train a formality classifier on this column.

Known limitations

• It is synthetic. Every string here was written by a language model against a schema, not transcribed from a corpus or checked by a lexicographer. It is well-formed and internally consistent; it is not attested usage, and it will contain confident errors. Do not use it as ground truth about what a word means.
• Judge scores 70.2/100 (core + tier 2) and 66.7/100 (tier 3). A different model family (Claude Opus) scored fixed 40-entry stratified samples at the close of each build. Sample statistics, not per-entry guarantees, and the judge is itself a model.
• Relation precision is the weakest axis. Relations were judged for validity and the ones that failed were demoted rather than asserted; symmetric reciprocity finished at 94.3% for synonyms and 95.3% for antonyms, and 1,890 senses were left with no relation at all. Treat a single edge as a hypothesis, not a fact; treat the aggregate graph as usable.
• core, tier2, tier3 and tier4 are deliberately partial. 109,633 lexemes across core, tier2, tier3 and tier4 received the text stages (glosses, examples, encyclopedia) but not the queries, QA pairs, contrasts or register renditions. The coverage table above gives the exact per-field share; nothing is hidden behind an average.
• The encyclopedia is entry-level. One article per headword, about the headword as a whole. On a polysemous entry it is not a description of any one sense, and it is never used as a positive for one (D-71). It is entry-level reference prose, not a specialist article.
