# english nouns

## step 1a

get freqency source list + verify lemmatization + confirm language/POS tagging

example:

house
bank
asdf

## step 1b

transform list into JSON (headword, language, POS)

example:

```json
{
    "headword": "house",
    "language": "en",
    "pos": "noun"
},
{
    "headword": "bank",
    "language": "en",
    "pos": "noun"
},
{
    "headword": "asdf",
    "language": "en",
    "pos": "noun"
}
```

---

## step 2a

check existence in kaikki (eg. is there a english noun "asdf" in kaikki, if not put it separate list)

example output:

```json
{
    "headword": "house",
    "language": "en",
    "pos": "noun"
},
{
    "headword": "bank",
    "language": "en",
    "pos": "noun"
}
```

miss list (triage queue, not trash! contains junk, slipped inflections, and real Kaikki gaps, gets handled separately, never auto-drop!)

```json
{ "headword": "asdf", "language": "en", "pos": "noun" }
```

## step 2b

for each sense, extract: glosses, translations (with gender), examples
id will be generated via: `headword:lang:pos:sense_index`

words without glosses will be dropped! (put in special list)

example output:

```json
{
  "id": "house:en:noun:0",
  "headword": "house",
  "language": "en",
  "pos": "noun",
  "sense": ["A building for human habitation."],
  "examples": ["They bought a house in the city."],
  "translations": {
    "de": [{ "word": "Haus", "gender": "neuter" }],
    "it": [{ "word": "casa", "gender": "feminine" }],
    "es": [{ "word": "casa", "gender": "feminine" }],
    "fr": [{ "word": "maison", "gender": "feminine" }]
  }
},
{
  "id": "house:en:noun:1",
  "headword": "house",
  "language": "en",
  "pos": "noun",
  "sense": ["A noble family or lineage."],
  "examples": ["The House of Tudor ruled England."],
  "translations": {
    "de": [
      { "word": "Adelsgeschlecht", "gender": "neuter" },
      { "word": "Haus", "gender": "neuter" }
    ]
  }
},
{
  "id": "bank:en:noun:0",
  "headword": "bank",
  "language": "en",
  "pos": "noun",
  "sense": ["An institution where one can place and borrow money."],
  "examples": ["She deposited her paycheck at the bank."],
  "translations": {
    "de": [{ "word": "Bank", "gender": "feminine" }],
    "it": [{ "word": "banca", "gender": "feminine" }],
    "es": [{ "word": "banco", "gender": "masculine" }],
    "fr": [{ "word": "banque", "gender": "feminine" }]
  }
},
{
  "id": "bank:en:noun:1",
  "headword": "bank",
  "language": "en",
  "pos": "noun",
  "sense": ["The land alongside a river or lake."],
  "examples": ["They picnicked on the bank of the river."],
  "translations": {
    "de": [{ "word": "Ufer", "gender": "neuter" }],
    "it": [{ "word": "riva", "gender": "feminine" }],
    "es": [{ "word": "orilla", "gender": "feminine" }],
    "fr": [{ "word": "rive", "gender": "feminine" }]
  }
},
{
  "id": "bank:en:noun:2",
  "headword": "bank",
  "language": "en",
  "pos": "noun",
  "sense": ["A collection or store of something held in reserve."],
  "examples": ["The hospital keeps a blood bank."],
  "translations": {
    "de": [{ "word": "Bank", "gender": "feminine" }]
  }
}
```

## step 2c

fill gaps Kaikki left (LLM, 3 models, generate-then-vote)

takes 2b's partial cards. 3 different-family models (qwen, llama, gemma) generate, then vote.

separate focused sub-passes, one field at a time — never combined:

- **translations** → per missing language, generated with the gloss as context. generate → vote. no agreement → gap stays (cloud audit later)
- **examples** → for senses with no Kaikki example. generate → verify-vote ("is this a valid example of the gloss?"), since freeform sentences never exact-match. no agreement → no example (card still valid) no tiebreak: no agreement leaves the gap, never escalates to more models. vote records stored in pipeline.db for the cloud audit.
- **invariant**: the gloss is never LLM-generated — translations are filled, examples generated, difficulty graded, but the gloss must always be Kaikki's (no gloss → sense dropped in 2b)

example input:

```json
{
  "id": "harbor:en:noun:0",
  "headword": "harbor",
  "language": "en",
  "pos": "noun",
  "glosses": ["A sheltered area of water where ships can dock safely."],
  "examples": [],
  "translations": { "de": [{ "word": "Hafen", "gender": "masculine" }] }
}
```

next substage is the translation generation:

```json
{
  "id": "harbor:en:noun:0",
  "headword": "harbor",
  "language": "en",
  "pos": "noun",
  "glosses": ["A sheltered area of water where ships can dock safely."],
  "examples": [],
  "translations": {
    "de": [{ "word": "Hafen", "gender": "masculine" }],
    "it": [{ "word": "porto", "gender": null }],
    "es": [{ "word": "puerto", "gender": null }],
    "fr": [{ "word": "port", "gender": null }]
  }
}
```

next substage is the gender modification (by looking up kaikki for it/es/fr or corresponding wiktionary, fill only nulls, not touching existing genders):
**runs only after all genders are present**

```json
{
  "id": "harbor:en:noun:0",
  "headword": "harbor",
  "language": "en",
  "pos": "noun",
  "glosses": ["A sheltered area of water where ships can dock safely."],
  "examples": [],
  "translations": {
    "de": [{ "word": "Hafen", "gender": "masculine" }],
    "it": [{ "word": "porto", "gender": "masculine" }],
    "es": [{ "word": "puerto", "gender": "masculine" }],
    "fr": [{ "word": "port", "gender": "masculine" }]
  }
}
```

next substage is the example generation:

```json
{
  "id": "harbor:en:noun:0",
  "headword": "harbor",
  "language": "en",
  "pos": "noun",
  "glosses": ["A sheltered area of water where ships can dock safely."],
  "examples": ["The fishing boats returned to the harbor at dusk."],
  "translations": {
    "de": [{ "word": "Hafen", "gender": "masculine" }],
    "it": [{ "word": "porto", "gender": "masculine" }],
    "es": [{ "word": "puerto", "gender": "masculine" }],
    "fr": [{ "word": "port", "gender": "masculine" }]
  }
}
```

## step 3

adding difficulty level

CEFR is mapped to three buckets:
A1/A2 → easy
B1/B2 → intermediate
C1/C2 → hard

depending on number of senses per headword:

- One sense → derive difficulty from the CEFRLex distribution (first CEFR level crossing a frequency threshold, mapped to a bucket, not the peak), for the four covered languages (en/de/es/fr). Deterministic, no LLM
- Multiple senses → the three local LLMs grade each sense (easy/intermediate/hard) from the gloss. CEFRLex not involved.
- No CEFRLex entry at all (Italian, or single-sense word that's missing) → LLMs grade from gloss

to get coverage (not quality), 3 local llms are going to be used: gemma, qwen and llama

on the llm votes:

- **Majority agrees (3-0 or 2-1)** → ship the majority value.
- **3-way split (all three differ)** → no consensus → exclude the card to the review queue. Not shipped.

example output:

```json
{
  "id": "house:en:noun:0",
  "headword": "house",
  "language": "en",
  "pos": "noun",
  "difficulty_level": "easy",
  "glosses": ["A building for human habitation."],
  "examples": ["They bought a house in the city."],
  "translations": {
    "de": [{ "word": "Haus", "gender": "neuter" }],
    "it": [{ "word": "casa", "gender": "feminine" }],
    "es": [{ "word": "casa", "gender": "feminine" }],
    "fr": [{ "word": "maison", "gender": "feminine" }]
  }
},
{
  "id": "house:en:noun:1",
  "headword": "house",
  "language": "en",
  "pos": "noun",
  "difficulty_level": "hard",
  "glosses": ["A noble family or lineage."],
  "examples": ["The House of Tudor ruled England."],
  "translations": {
    "de": [
      { "word": "Adelsgeschlecht", "gender": "neuter" },
      { "word": "Haus", "gender": "neuter" }
    ]
  }
}
```

**important**: `difficulty_level` is mandatory on every shipped card (the user sets difficulty before a game)

This is coverage, not final quality: three local models make every shipped card's difficulty present and plausible, but not guaranteed correct

no cefr list: needs to be graded by online llms (see notes)

## coverage report (trial deliverable)

- not a data stage => reads the finished cards and summarises them
- the trial (english + italian nouns, local models) runs steps 1a→3 then emits a report

### pipeline health — did it run?

- input lemmas → output cards (ratio; multi-sense makes cards > lemmas)
- dropped per stage + why: 2a misses (junk/inflection/gap), 2b no-gloss drops, 3 no-consensus exclusions
- parse failures / errors

### coverage — how complete?

- translation completeness: all 4 langs vs gaps, per language
- examples: from Kaikki vs LLM-generated vs none
- gender: translations still null after Wiktionary fill
- difficulty distribution per bucket (lopsided = broken CEFRLex threshold or bad grading)

### local good enough? — model agreement

- difficulty votes: 3-0 / 2-1 / 3-way split rates (high 3-way = locals can't do it → need cloud)
- translation gap-fill: agreement rate, gaps left unfilled
- → go/no-go on local-for-launch

### rent vs API? — workload volume

- total LLM calls across 2c + 3 (× per-token rate = API cost)
- cards needing LLM vs handled deterministically (english: high deterministic; italian: ~0, no CEFRLex)
- per-language call counts → scale english (low) and italian (high) to estimate the middle three

### review backlog — what's deferred

- miss-list size + composition, per language
- no-consensus exclusions (cloud-audit queue size)
- unfilled translation gaps (also cloud-audit work)

**framing**: english = optimistic floor (rich Kaikki, CEFRLex exists, models strongest).
italian = pessimistic ceiling (no CEFRLex, thinner Kaikki). all five languages sit between.
read to decide, not to archive.

Notes:

- the miss list needs to get verified/re-worked later on
- the kaikki data contains ipas and links to audio files, add them later if needed, they are not needed now
- use online llms to set the difficulty(cefr) of the not shipped words
- add plurals from kaikki/wiktionary
- postgres sync to prod db
