Getting Started

Before we dive into the tasks, ensure that you have the necessary prerequisites installed:

• torch==1.4.0
• spacy==2.1.8
• torchtext==0.4.0
• seqeval==0.0.12
• pytorch-nlp==0.4.1

For mixed precision training, you’ll need to install apex.

Once everything is set up, you can clone the toolkit from GitHub and install it:

git clone https://github.com/plkmo/NLP_Toolkit.git
cd NLP_Toolkit
pip install .
python -m spacy download en_core_web_lg

Exploring Each Task

1. Classification

The goal of classification is to segregate documents into appropriate classes based on their content. You can use models like BERT and XLNet for this purpose.

To run the classification model, format your training data as follows:

train.csv:
text,label
"Document Text 1",0
"Document Text 2",1

Then run the classification script:

python classify.py --train_data ./data/train.csv --infer_data ./data/infer.csv

2. Automatic Speech Recognition

This function converts audio signals into text using models like Speech-Transformer. Create a folder structure for your audio data, and then run:

python speech.py --folder train-clean-5

3. Text Summarization

Text summarization reduces lengthy content to concise sentences. Prepare your dataset and run this simple command:

python summarize.py --data_path ./data/example.csv

4. Machine Translation

Machine translation translates text between languages. For example:

python translate.py --src_path ./data/src.txt --trg_path ./data/trg.txt --src_lang en --trg_lang fr

5. Natural Language Generation

Natural Language Generation creates coherent text replies based on past context; simply invoke:

python generate.py --model_no 0

6. Punctuation Restoration

This task restores punctuation into unformatted text:

python punctuate.py --data_path ./data/tags.en-fr.en

7. Named Entity Recognition

NER identifies entities like persons or organizations. For a recognized sample, run:

python ner.py --train_path ./data/train.txt --test_path ./data/test.txt

8. POS Tagging

The Parts-of-speech tagging, assigns grammatical roles to each word. Run with:

python pos.py --train_path ./data/train.txt --test_path ./data/test.txt

9. Unsupervised Style Transfer

This changes the style of sentences while preserving their content. Execute it by running:

python style_transfer.py --data_path ./data/style_data

10. Text Clustering

For clustering media into similar groups, run:

python cluster.py --train_data ./data/train.csv

11. Grammatical Error Correction

To correct grammatical errors, run:

python gec.py

Troubleshooting

If you encounter issues, here are a few common troubleshooting ideas:

• Ensure all dependencies are installed correctly.
• Check if your data files are appropriately formatted.
• Refer to the log files for specific errors.
• Revisit the installation steps to ensure nothing was missed.
• If further issues arise, visit the project’s GitHub repository for more guidance.
