# t5-small-spoken-typo |
|
|
|
This model is a fine-tuned version of T5-small, adapted for correcting typographical errors and missing spaces in text. It has been trained on a combination of spoken corpora, including DailyDialog and BNC, with a focus on short utterances common in conversational English. |
|
|
|
## Task |
|
The primary task of this model is **Text Correction**, with a focus on: |
|
- **Sentence Correction**: Enhancing readability by correcting sentences with missing spaces or typographical errors. |
|
- **Text Normalization**: Standardizing text by converting informal or irregular forms into more grammatically correct formats. Largely dealing with sentences with no spaces |
|
|
|
This model is aimed to support processing user-generated content where informal language, abbreviations, and typos are prevalent, aiming to improve text clarity for further processing or human reading. |
|
|
|
|
|
## Usage |
|
|
|
```python |
|
from happytransformer import HappyTextToText, TTSettings |
|
|
|
happy_tt = HappyTextToText("T5", "willwade/t5-small-spoken-typo") |
|
|
|
args = TTSettings(num_beams=5, min_length=1) |
|
|
|
# Add the prefix "grammar: " before each input |
|
result = happy_tt.generate_text("grammar: Hihowareyoudoingtaday?.", args=args) |
|
|
|
print(result.text) # This sentence has bad grammar and is comrpessed. |
|
``` |
|
|
|
or using vanilla transformers |
|
|
|
```python |
|
from transformers import T5Tokenizer, T5ForConditionalGeneration |
|
|
|
# Load the tokenizer and model |
|
model_name = "willwade/t5-small-spoken-typo" |
|
tokenizer = T5Tokenizer.from_pretrained(model_name) |
|
model = T5ForConditionalGeneration.from_pretrained(model_name) |
|
|
|
# Prepare the input text with the "grammar: " prefix |
|
input_text = "grammar: Hihowareyoudoingtaday?." |
|
input_ids = tokenizer.encode(input_text, return_tensors="pt") |
|
|
|
# Generate text |
|
# Adjust num_beams and min_length to your needs |
|
output = model.generate(input_ids, num_beams=5, min_length=1, max_new_tokens=50, early_stopping=True) |
|
|
|
# Decode the generated text |
|
decoded_output = tokenizer.decode(output[0], skip_special_tokens=True) |
|
|
|
print(decoded_output) |
|
|
|
``` |
|
|
|
# Model Details |
|
|
|
## Model Description |
|
The `t5-small-spoken-typo` model is specifically designed to tackle the challenges of text correction within user-generated content, particularly in short, conversation-like sentences. It corrects for missing spaces, removes unnecessary punctuation, corrects typos, and normalizes text by replacing informal contractions and abbreviations with their full forms. |
|
It has been training on |
|
- [BNC 2014 Spoken](http://cass.lancs.ac.uk/cass-projects/spoken-bnc2014/) |
|
- [Daily Dialog](https://huggingface.co/datasets/daily_dialog) |
|
- [Comm2 - AAC Text](https://www.aactext.org/comm2/) |
|
- [C4-200M - 25K Subset](https://huggingface.co/datasets/leslyarun/c4_200m_gec_train100k_test25k) |
|
- [JFLEG](https://huggingface.co/datasets/jhu-clsp/jfleg) |
|
- [Coedit](https://huggingface.co/datasets/grammarly/coedit) |
|
- [Conversation Enders](https://huggingface.co/Chakshu/conversation_ender) |
|
- [Conversation Starters](https://huggingface.co/Langame/conversation-starters) |
|
|
|
|
|
Then injecting typos from a range of places |
|
- **Using NLPAUG** We've made some typos in Comm2 by usiing this library https://github.com/makcedward/nlpaug |
|
- **Typo lists, Birkbeck, etc.**: These datasets contain lists of commonly misspelled words, making them invaluable for training models to recognize and correct spelling errors. |
|
- Find these resources [here](https://www.dcs.bbk.ac.uk/~ROGER/corpora.html). |
|
- **TOEFL Spell** A dataset of Spelling Annotations for English language learner essays written for TOEFL exams. |
|
- Find this [here](https://github.com/EducationalTestingService/TOEFL-Spell/tree/master) |
|
- **Homonyms** We replace words in BNC and Dialy Dialog occasionally with homonyms from this list https://github.com/pimentel/homophones |
|
- **Our own typo augment function** This would make likely errors found in a English Qwerty layout as well as subsitutions, deletions etc |
|
|
|
And then compressing versions of the sentences (i.e. removing spaces)- both correct and typod we add to our dataset. (This is to solve a problem where some people write without spaces) |
|
Note we use a ``grammar: `` prefix for each sentence in training. |

# Uses |
|
|
|
## Direct Use |
|
This model can be directly applied for correcting text in various applications, including but not limited to, enhancing the quality of user-generated content, preprocessing text for NLP tasks, and supporting assistive technologies. |
|
|
|
## Out-of-Scope Use |
|
The model might not perform well on text significantly longer than the training examples (2-5 words), highly formal documents, or languages other than English. Use in sensitive contexts should be approached with caution due to potential biases. **Our typical use case here is AAC users - i.e. users using technology to communicate face to face to people** |
|
|
|
# Bias, Risks, and Limitations |
|
|
|
The model may inherit biases present in its training data, potentially reflecting or amplifying societal stereotypes. Given its training on conversational English, it may not generalize well to formal text or other dialects and languages. |
|
|
|
## Recommendations |
|
Users are encouraged to critically assess the model's output, especially when used in sensitive or impactful contexts. Further fine-tuning with diverse and representative datasets could mitigate some limitations. |
|
|
|

|
## Training Data |
|
The model was trained on a curated subset of the DailyDialog and BNC corpora (2014 spoken), focusing on sentences 2-5 words in length, with manual introduction of typos and removal of spaces for robustness in text correction tasks.You can see the code to pre-process this [here](https://github.com/willwade/dailyDialogCorrections/tree/main) |
|
|
|
## Training Procedure |
|
|
|
### Preprocessing |
|
Sentences were stripped of apostrophes and commas, spaces were removed, and typos were introduced programmatically to simulate common errors in user-generated content. |
|
|
|
### Speeds, Sizes, Times |
|
- Training was conducted on LlambdaLabs, taking approximately 12 hrs to complete. |

## Testing Data, Factors & Metrics |
|
|
|
### Testing Data |

|
|
|
|
|
## Results |
|
The model demonstrates high efficacy in correcting short, erroneous sentences, with particular strength in handling real-world, conversational text. |
|
|
|
It performs nearly on par with GPTTurbo16k at around 93% sentence similarity. But there are gaps. |
