Project History
Fake News Classification
https://github.com/LiamNiisan/fake_news_detectionTwo models were trained and compared. A linear model with FastText and a neural model with TensorFlow. With the training data, the neural model gave the best results, but on manually annotated data from online news, FastText performed much better.
This showed that linear models are very good at generalizing, and neural models need to be trained on lots of good data to perform well.
Legal Corpus NER
https://github.com/LiamNiisan/legal-corpus-NERThe data was scrapped from BC's Court of Appeal and Supreme Court and was annotated using label-studio.
BERT for Hate Speech Detection
https://github.com/LiamNiisan/BERT-Fine-Tuning-Hate-Speech-DetectionBGC NASA Landslide Detection
https://github.com/LiamNiisan/BGC-NASA-landslide-detectionThe project consists of two parts:
1. News articles are extracted from online sources and then passed to a model that extracts the landslide's event properties.
2. The model extracts information from the articles: time, location, casualties, landslide category, and landslide trigger.
