| # Running the extractor |
|
|
| `gemination.py` has no dependencies of its own. To turn new words into |
| gemination patterns it needs HornMorpho 5.3.6 (Michael Gasser, |
| https://github.com/hltdi/HornMorpho) with two small patches. |
|
|
| ## One command |
|
|
| ```bash |
| ./install_hornmorpho.sh .venv-hm # Python 3.9 or newer; set PYTHON=... to choose one |
| LANG=C.UTF-8 .venv-hm/bin/python gemination.py ይገኛል ክልል መለወጥ |
| LANG=C.UTF-8 .venv-hm/bin/python test_gemination.py |
| ``` |
|
|
| Expected output of the second line (tab-separated): |
|
|
| ``` |
| ይገኛል ይገ፟ኛ፟ል positions=[1, 2] sources=['t-prefix', 'root'] pos=V root_freq=3688 seg=----ይ</ገ/ኝ>---ኣ/ል--- |
| ክልል ክል፟ል positions=[1] sources=['lexicon'] pos=N root_freq=1 seg=-<ክ/ልል>------ |
| መለወጥ መለ፟ወጥ positions=[1] sources=['t-prefix'] pos=N root_freq=84 seg=-<መ/-ለወጥ>------ |
| መለወጥ መለወ፟ጥ positions=[2] sources=['root'] pos=N root_freq=84 seg=-<መ-ለ/ወጥ>------ |
| ``` |
|
|
| መለወጥ has two readings (passive mälläwäṭ, active mäläwwäṭ), so it prints two |
| patterns. Only sentence context can choose between them. |
|
|
| ## What the script does, step by step |
|
|
| 1. **Install the wheel.** HornMorpho is not on PyPI. The script downloads |
| `dist/hornmorpho-5.3.6-py3-none-any.whl` from the HornMorpho repository at |
| commit `7e3d93af760e27ea6dbc3b7a078d2d9c3335f618` and checks its sha256 |
| (`e1b0e4ed...fa7`). Dependencies `conllu` and `requests` come with it. |
| 2. **Patch 1, Tk GUI stub** (`patches/gui.py`, replaces `hm/morpho/gui.py`). |
| `hm/morpho/corpus.py` does `from .gui import *` at import time, so |
| `import hm` fails on any Python without `_tkinter`. The stub defines the |
| one name `corpus.py` refers to. Applied only when `import tkinter` fails. |
| 3. **Patch 2, lexicon loader** (`patches/morphology.patch`, applied with |
| `patch -p1` inside site-packages). `words1.srf` lines are |
| `ortho phon POS` with `#` comment lines, but the loader built a dict from |
| the raw split, which raises on the first real entry. |
| 4. **Amharic data.** `src/hm/languages/a.tgz` from the same commit |
| (sha256 `3274f71d...95c`), unpacked into `hm/languages/`. |
|
|
| Always run with a UTF-8 locale (`LANG=C.UTF-8`). |
|
|
| ## The call that matters |
|
|
| ```python |
| import hm |
| readings = list(hm.anal("a", "ይገኛል", degem=False)) # degem=False keeps the '/' marks |
| ``` |
|
|
| With the default `degem=True` the `/` marks are stripped from `seg`, and the |
| only gemination information left is the `+gemN` root feature, which misses |
| every geminate created by a prefix or a suffix. That was the bug in v1 of this |
| lexicon. |
|
|
| ```python |
| import gemination as G |
| G.analyze("ይገኛል") # runs HornMorpho, returns patterns, most frequent root first |
| G.word_gemination(word, readings) # same, from readings you already have |
| G.reading_gemination(word, {"seg": "----ይ</ገ/ኝ>---ኣ/ል---"}) # one seg, no HornMorpho needed |
| G.mark("ይገኛል", [1, 2]) # 'ይገ፟ኛ፟ል' |
| ``` |
|
|
| ## Rebuilding the release files |
|
|
| `build_lexicon.py` converts the internal lexicon (one entry per word with the |
| stored HornMorpho segs) into `data/`. It re-derives every pattern from its segs |
| and stops if any disagrees, so the data cannot drift from this extractor. |
