Western Tropical Astrology SFT Dataset

Tropical-zodiac natal chart readings (Sun/Moon/Ascendant + classical planetary dignities), computed via Swiss Ephemeris, no ayanamsa correction.

Total examples	100000
Train / Validation / Test	89916 / 5104 / 4980
Question types	4
Avg citations per example	3.047
Zero-citation examples	2648

Computation

Deterministic astronomy (pyswisseph, tropical zodiac — the zodiac frame used by most Western astrology, as opposed to the sidereal frame used by Vedic astrology).

Validation status — read before trusting this at scale

Reuses the same rashi/nakshatra math validated in the companion Jyotish-LLM project; only the zodiac reference point changes (no ayanamsa subtraction). Not independently re-validated for tropical-specific reference charts in this version — the underlying astronomy is the same code path.

What this dataset does NOT claim

Like every dataset in this collection, this teaches a model to narrate a correctly-computed Western Tropical Astrology reading using its own traditional rules faithfully and with citations. It does not, and cannot, contain any ground truth about whether any prediction comes true — no such data exists for any divination system. See the companion repo's top-level README for the shared "what these datasets don't claim" statement that applies across the whole collection.

Known limitations

• Uses the same 15-yoga/dignity rule set as the Vedic system — some naming (e.g. 'Yoga') is Vedic terminology applied to a tropical chart; Western astrology traditionally uses different terms (aspects, dignities) for equivalent concepts. Functionally correct, terminologically mixed.
• No house-system aspects (trine, square, conjunction between planets) — only sign placement and the shared dignity/yoga rule set.
• No outer planets (Uranus, Neptune, Pluto) — only the 7 classical planets + nodes, consistent with the rest of this repo.

Companion repo

Full generation pipeline (8 systems, shared scripts) — for regenerating at larger scale or extending the rule set — is the companion GitHub repo astrology-datasets (update this link once pushed).
