| # Sanskrit Samas (Compound) Dataset — V1 |
|
|
| Grammar-grounded training data for **Sanskrit samas (compounds)** covering all |
| 7 samasa types, with **laukik vigraha** (natural paraphrase) and **alaukik |
| vigraha** (Pāṇinian sUP analysis) on every row. |
|
|
| Companion to [`sanskrit-sandhi-boundaries-v2`](https://huggingface.co/datasets/CodeIsAbstract/sanskrit-sandhi-boundaries-v2) |
| (sentence-level external sandhi). Merge both for a full sandhi+samas boundary |
| training set. |
|
|
| ## Dataset |
|
|
| - **Rows**: 258,408 |
| - **Checksum**: `e7c0a804c109` |
| - **Builder**: `benchmarks/build_samas_data.py` (deterministic, seed 42) |
| - **Format**: JSONL (one compound per line) |
|
|
| ## Schema (per row) |
|
|
| | Field | Type | Description | |
| |-------|------|-------------| |
| | `surface` | string | Natural merged SLP1 surface (internal sandhi applied at the seam) | |
| | `devanagari` | string | Devanagari rendering | |
| | `pieces` | list[str] | Surface partition at the compound seam (splitter contract; `"".join == surface`) | |
| | `bnd` | list[int] | Boundary positions (training format; last-char indices) | |
| | `gold_words` | list[str] | **Laukik vigraha** — natural paraphrase with explicit case forms | |
| | `gold_alaukik` | string | **Alaukik vigraha** — Pāṇinian analysis: stems + sUP tags (e.g. `rAma + Nas + puruSa + su~`) | |
| | `samasa_type` | string | One of the 7 types | |
| | `stem1`, `stem2` | string | The constituent stems | |
|
|
| ## Samasa types covered |
|
|
| | Type | Meaning | Example (laukik) | n | |
| |------|---------|------------------|---| |
| | tatpuruṣa | determinative (X of Y) | rājasya puruṣaḥ | 62,893 | |
| | karmadhāraya | appositional (X that is Y) | nīlam utpalam | 62,893 | |
| | dvandva | copulative (X and Y) | rāmaḥ ca kṛṣṇaḥ ca | 59,924 | |
| | bahuvrīhi | exocentric "having X" | cakraṃ pāṇau yasya saḥ | 60,172 | |
| | avyayībhāva | adverbial | śaktim anatikramya | 7,097 | |
| | amreḍita | reduplicative | dine dine | 5,091 | |
| | dvigu | numerical | trayo lokāḥ | 338 | |
|
|
| ## Construction (Pāṇinian) |
|
|
| 1. First member(s) lose their case endings → bare stem (prātipadika). |
| 2. Last member keeps its own case ending. |
| 3. Internal sandhi applies at the seam (same rules as external sandhi). |
| 4. The compound takes ONE case ending on the last member. |
|
|
| Alaukik vigraha is generated from **vidyut prakriya derivation history** — |
| the exact sUP tags (su~, am, wA, Ne, Nasi~, Nas, Ni × Eka/Dvi/Bahu) are |
| recovered from the Pāṇinian derivation steps. |
|
|
| ## Integrity |
|
|
| - 0 rows fail `"".join(pieces) == surface`. |
| - Every seam is rejoin-verified by the sandhi engine. |
| - Builder deterministic (seed 42): reproducible byte-for-byte. |
