# Model Overview
This is an `xlm-roberta` fine-tuned to restore punctuation, true-case (capitalize),
and detect sentence boundaries (full stops) in 47 languages.
Note that the widget may not be working yet; HF requires models to be public before running the widget, so it cannot be tested before making it available.
# Usage
The easiest way to use this model is to install [punctuators](https://github.com/1-800-BAD-CODE/punctuators):
```bash
$ pip install punctuators
```
Though this is just an ONNX and SentencePiece model, so you may run it as you wish.
The input to the `punctuators` API is a list (batch) of strings.
Each string will be punctuated, true-cased, and segmented on predicted full stops.
The output will therefore be a list of list of strings: one list of segmented sentences per input text.
To disable full stops, use `m.infer(texts, apply_sbd=False)`.
The output will then be a list of strings: one punctuated, true-cased string per input text.
Example Usage
```python
from typing import List
from punctuators.models import PunctCapSegModelONNX

# Model Architecture
This model implements the following graph, which allows punctuation, true-casing, and fullstop prediction
in every language without language-specific behavior:
We start by tokenizing the text and encoding it with XLM-Roberta, which is the pre-trained portion of this graph.
Then we predict punctuation before and after every subtoken.
Predicting before each token allows for Spanish inverted question marks.
Predicting after every token allows for all other punctuation, including punctuation within continuous-script
languages and acronyms.
We use embeddings to represent the predicted punctuation tokens to inform the sentence boundary head of the
punctuation that'll be inserted into the text. This allows proper full stop prediction, since certain punctuation
tokens (periods, questions marks, etc.) are strongly correlated with sentence boundaries.
We then shift full stop predictions to the right by one, to inform the true-casing head of where the beginning
of each new sentence is. This is important since true-casing is strongly correlated to sentence boundaries.
For true-casing, we predict `N` predictions per subtoken, where `N` is the number of characters in the subtoken.
In practice, `N` is the maximum subtoken length and extra predictions are ignored. Essentially, true-casing is
modeled as a multi-label problem. This allows for upper-casing arbitrary characters, e.g., "NATO", "MacDonald", "mRNA", etc.
Applying all these predictions to the input text, we can punctuate, true-case, and split sentences in any language.
## Tokenizer
Instead of the hacky wrapper used by FairSeq and strangely ported (not fixed) by HuggingFace, the `xlm-roberta` SentencePiece model was adjusted to correctly encode
the text. Per HF's comments,
```python
# Original fairseq vocab and spm vocab must be "aligned":
# Vocab | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9
# -------- | ------- | ------- | ------ | ------- | --- | --- | --- | ----- | ----- | ----
# fairseq | '' | '' | '' | '' | ',' | '.' | '▁' | 's' | '▁de' | '-'
# spm | '' | '' | '' | ',' | '.' | '▁' | 's' | '▁de' | '-' | '▁a'
```
The SP model was un-hacked with the following snippet
(SentencePiece experts, let me know if there is a problem here):
```python
from sentencepiece import SentencePieceProcessor
from sentencepiece.sentencepiece_model_pb2 import ModelProto
m = ModelProto()
m.ParseFromString(open("/path/to/xlmroberta/sentencepiece.bpe.model", "rb").read())
pieces = list(m.pieces)
pieces = (
[
ModelProto.SentencePiece(piece="", type=ModelProto.SentencePiece.Type.CONTROL),
ModelProto.SentencePiece(piece="", type=ModelProto.SentencePiece.Type.CONTROL),
ModelProto.SentencePiece(piece="", type=ModelProto.SentencePiece.Type.CONTROL),
ModelProto.SentencePiece(piece="", type=ModelProto.SentencePiece.Type.UNKNOWN),
]
+ pieces[3:]
+ [ModelProto.SentencePiece(piece="", type=ModelProto.SentencePiece.Type.USER_DEFINED)]
)
del m.pieces[:]
m.pieces.extend(pieces)
with open("/path/to/new/sp.model", "wb") as f:
f.write(m.SerializeToString())
```
Now we can use just the SP model without a wrapper.
## Post-Punctuation Tokens
This model predicts the following set of punctuation tokens after each subtoken:
| Token | Description | Relevant Languages |
| ---: | :---------- | :----------- |
| \ | No punctuation | All |
| \ | Every character in this subword is followed by a period | Primarily English, some European |
| . | Latin full stop | Many |
| , | Latin comma | Many |
| ? | Latin question mark | Many |
| ？ | Full-width question mark | Chinese, Japanese |
| ， | Full-width comma | Chinese, Japanese |
| 。 | Full-width full stop | Chinese, Japanese |
| 、 | Ideographic comma | Chinese, Japanese |
| ・ | Middle dot | Japanese |
| । | Danda | Hindi, Bengali, Oriya |
| ؟ | Arabic question mark | Arabic |
| ; | Greek question mark | Greek |
| ። | Ethiopic full stop | Amharic |
| ፣ | Ethiopic comma | Amharic |
| ፧ | Ethiopic question mark | Amharic |
## Pre-Punctuation Tokens
This model predicts the following set of punctuation tokens before each subword:
| Token | Description | Relevant Languages |
| ---: | :---------- | :----------- |
| \ | No punctuation | All |
| ¿ | Inverted question mark | Spanish |
# Training Details
This model was trained in the NeMo framework.
This model was trained on an A100 for approximately 9 hours.
## Training Data
This model was trained with News Crawl data from WMT.
1M lines of text for each language was used, except for a few low-resource languages which may have used less.
Languages were chosen based on whether the News Crawl corpus contained enough reliable-quality data as judged by the author.
# Limitations
## Domain
This model was trained on news data, and may not perform well on conversational or informal data.
## Quality
This model is unlikely to be of production quality.
It was trained with "only" 1M lines per language, and the dev sets may have been noisy due to the nature of web-scraped news data.
## Excessive Predictions
This model over-predicts Spanish question marks, especially the inverted question mark `¿` (see metrics below).
Since `¿` is a rare token, especially in the context of a 47-language model, Spanish questions were over-sampled
by selecting more of these sentences from additional training data that was not used. However, this seems to have
"over-corrected" the problem and a lot of Spanish question marks are predicted.
The model may also over-predict commas.
# Evaluation
In these metrics, keep in mind that
1. The data is noisy
2. Sentence boundaries and true-casing are conditioned on predicted punctuation, which is the most difficult task and sometimes incorrect.
When conditioning on reference punctuation, true-casing and SBD is practically 100% for most languages.
4. Punctuation can be subjective. E.g.,
`Hola mundo, ¿cómo estás?`
or
`Hola mundo. ¿Cómo estás?`
When the sentences are longer and more practical, these ambiguities abound and affect all 3 analytics.
## Test Data and Example Generation
Each test example was generated using the following procedure:
1. Concatenate 11 random sentences (1 + 10 for each sentence in the test set)
2. Lower-case the concatenated sentence
3. Remove all punctuation
Targets are generated as we lower-case letters and remove punctuation.
The data is a held-out portion of News Crawl, which has been deduplicated.
3,000 lines of data per language was used, generating 3,000 unique examples of 11 sentences each.
We generate 3,000 examples, where example `i` begins with sentence `i` and is followed by 10 random
sentences selected from the 3,000 sentence test set.
For measuring true-casing and sentence boundary detection, reference punctuation tokens were used for
conditioning (see graph above). If we use predicted punctuation instead, then incorrect punctuation will
result in true-casing and SBD targets not aligning correctly and these metrics will be artificially low.
## Selected Language Evaluation Reports
For now, metrics for a few selected languages are shown below.
Given the amount of work required to collect and pretty-print metrics in 47 languages, I'll add more eventually.
