Resources: - [Hate Speech Project Page](/topics/hatespeech) - https://hatespeechdata.com/ - [Hate speech detection: Challenges and solutions](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6701757/) - [HateBase](https://hatebase.org/) - [Resources and benchmark corpora for hate speech detection: a systematic review](https://link.springer.com/article/10.1007/s10579-020-09502-8) ## Meeting 25.3.22 - Learned about Transformers, BERT, LSTM and RNN. - Tried HuggingFace transformers library - Started Google Colab - executing sentiment analysis, hf transformers pipeline functions. - prepared datasets: ## Meeting 10.3.22 - Improvement of the report. - Installed Transformers and Anaconda Tasks: - Try [this model](https://huggingface.co/cardiffnlp/twitter-roberta-base-sentiment) with your own text. - Learn how Transformers Neural Network Works. Learn how Roberta Model training works. Learn how BERT model finetuning works. Write a short memo about your findings and papers read on this topic. - Pick a dataset: - https://huggingface.co/datasets/sentiment140 (english) - https://www.clarin.si/repository/xmlui/handle/11356/1054 (multilingua) - https://huggingface.co/datasets/tamilmixsentiment (english tamil code switch) - Grab baseline BERT type model and try to finetune it for sentiment classification. - For finetuning and evaluation you can use this scrip https://github.com/huggingface/transformers/tree/master/examples/pytorch/text-classification - For finetuning you will need to install CUDA and Pytorch. It can work on CPU or NOT. - If you need GPU, use the school server idoc.fei.tuke.sk or google Colab. - Continue working on the paper. - Remind me about the SCYR conference payment. ## Meeting 21.2.22 - Written a report about HS detection (in progress) Tasks: - Repair the report (rewrite copied parts, make the paragrapsh be logically ordered, teoreticaly - formaly define the HS detection, analyze te datasets in detail - how do they work. what metric do they use). - Install Hugging Face Transformers and come through a tutorial ## Meeting 31.1.22 - Read some blogs about transformers - Installed and tied transformers - Worked on the review paper - Picked the Twitter Dataset on keggle - still selecting a method Open tasks: - Continue to work on the paper and share the paper with us. - Prepare som ideas for the common discussion about the project. - [ ] Try to prepare an experiment with the selected dataset. - [ ] You can use the school CUDA infrastructre (idoc.fei.tuke.sk). - [ ] Set up a repository for experiments, use the school git server git.kemt.fei.tuke.sk. - [x] Get ready to post a paper on the school PhD conference SCYR, deadline is in the middle of February http://scyr.kpi.fei.tuke.sk/. ### Meeting 10.1.22 - Set up a git account https://github.com/ManoGS with script to prepare "twitter" dataset and "english" dataset for HS detection. - confgured laptop with (Anaconda) / PyCharm, pytorch, cuda gone throug some basic python tutorials. - Read some blogs how to use kaggle (dataset database). - tutorials on huggingface transformers - understanding sentiment analysis. Open tasks: - [x] Continue to work on the review - with datasets and methods (specified below). - [x] Read and make notes about transformers, neural language models and finentuning. - [ ] Pick feasible dataset and method to start with. - [ ] You can use the school CUDA infrastructre (idoc.fei.tuke.sk). - [ ] Set up a repository for experiments, use the school git server git.kemt.fei.tuke.sk. - [ ] Get ready to post a paper on the school PhD conference SCYR, deadline is in the middle of February http://scyr.kpi.fei.tuke.sk/. #### Meeting 16.12.21 - A report was provided (through Teams). - Installed Anaconda and started s Transformers tutorial - Started Dive into python book Task: - Report: Create a detailed list of available datasets for HS. - Report: Create a detailed description of the state of the art approaches for HS detection. - Practical: Continue with open tasks below. (pick datasetm, perform classification,evaluate the experiment.) #### Meeting 10.12.21 No report (just draft) was provided so far. 1. Read papers from below and make notes what you have learned fro the papers. For each note make a bibliographic citation. Write down authors of the paper, name paper of the paper, year, publisher and other important information. When you find out something, make a reference with a number to that paper. You can use a bibliografic manager software. Mendeley, Endnote, Jabref. 2. From the papers find out answers to the questions below. 3. Pick a hatespeech dataset. 4. Pick an approach and Python library for HS classification. 5. Create a [GIT](https://git.kemt.fei.tuke.sk) repository and share your experiment files. Do not commit data files, just links how to download the files. 6. Perform and evaluate experiments. #### Meeting 10.11.21 #### First tasks Prepare a report where you will explain: - what is hate speech detection, - where and why you can use hate-speech detection, - what are state-of-the-art methods for hate speech detection, - how can you evaluate a hate-speech detection system, - what datasets for hate-speech detection are available, The report should properly cite scientific bibliographical sources. Use a bibliography manager software, such as Mendeley. Create a [VPN connection](https://uvt.tuke.sk/wps/portal/uv/sluzby/vzdialeny-pristup-vpn) to the university network to have access to the scientific databses. Use scientific indexes to discover literature: - [Scopus](https://www.scopus.com/) (available from TUKE VPN) - [Scholar](httyps://scholar.google.com) Your review can start with: - [Hate speech detection: Challenges and solutions](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6701757/) - [HateBase](https://hatebase.org/) - [Resources and benchmark corpora for hate speech detection: a systematic review](https://link.springer.com/article/10.1007/s10579-020-09502-8) Get to know the Python programming language - Read [Dive into Python](https://diveintopython3.net/) - Install [Anaconda](https://www.anaconda.com/) - Try [HuggingFace Transformers library]( https://huggingface.co/transformers/quicktour.html)
