# About
This repository contains treebanks for Latin from the [Ancient Latin Dependency Treebank, version 1.7](http://nlp.perseus.tufts.edu/syntax/treebank/). The file `latin_treebank_perseus/ldt-1.5.xml` contains all of the treebank data.
# Part of speech
See `make_pos_models.py` for how models were created for the unigram, bigram, trigram, backoff (1, 2, 3), and crf models were made. They are kept in the `cltk/latin_models_cltk `_ repo.
The Lapos model was made with the Lapos tagger (`cltk/lapos `_) and the following command:
``` shell
$ ./lapos-learn -m ./model latin_training_set.pos
```

position in the sentence. The first word in a sentence is given
id 1.

root, its head is 0.
