Manohar Gowdru Shridhara

Beginning of the study: 2021

Disertation Thesis

in 2023/24

Hate Speech Detection

Goals:

• Write a dissertaion thesis
• Publish 2 A-class journal papers

Minimal Thesis

(preliminary dissertaion and exam in 2022/23)

Goals:

• Provide state-of-the-art overview.
• Formulate dissertation theses (describe scientific contribution of the thesis).
• Prepare to reach the scientific contribution.
• Publish 4 conference papers.

First year of PhD study

Goals:

• Provide state-of-the-art overview.
• Read and make notes from at least 100 scientific papers or books.
• Publish at least 2 conference papers.
• Prepare for minimal thesis.

Resources:

• Hate Speech Project Page
• https://hatespeechdata.com/
• Hate speech detection: Challenges and solutions
• HateBase
• Resources and benchmark corpora for hate speech detection: a systematic review

Meeting 10.3.22

• Improvement of the report.
• Installed Transformers and Anaconda

Tasks:

• Try this model 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.
• 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:

• Continue to work on the review - with datasets and methods (specified below).
• 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 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 to the university network to have access to the scientific databses. Use scientific indexes to discover literature:

• Scopus (available from TUKE VPN)
• Scholar

Your review can start with:

• Hate speech detection: Challenges and solutions
• HateBase
• Resources and benchmark corpora for hate speech detection: a systematic review

Get to know the Python programming language

• Read Dive into Python
• Install Anaconda
• Try HuggingFace Transformers library
