Our team was inspired to work on a project that tackles cyberbullying, an issue that's becoming increasingly prevalent in our digital world. We wanted to leverage our expertise in natural language processing (NLP) to develop a tool that can identify and predict instances of cyberbullying online.
What it does
Our project, called Cyberbullying Prediction Using NLP, uses machine learning algorithms to analyze text data and determine if a message contains elements of cyberbullying. This tool can be integrated into social media platforms and messaging apps to identify and flag potentially harmful content, alerting users and moderators.
How we built it
We used a dataset from Kaggle that has a list of uncleaned texts and which category of cyberbullying the text comes under. Next, we cleaned and preprocessed the text data to create a high-quality dataset that we could use to train our models. Using Python and several NLP libraries such as NLTK and spaCy, we performed feature extraction, model training, and prediction. We validated our models using cross-validation and evaluated their performance using various metrics such as accuracy, precision, recall, and F1-score.
Challenges we ran into
One of the biggest challenges we faced was cleaning the data which had too much noise. Additionally, we had to deal with challenges related to data preprocessing, such as handling misspellings, slang, and other forms of non-standard language. Finally, we had to carefully fine-tune our models to ensure they were both accurate and effective at detecting cyberbullying.
Accomplishments that we're proud of
We're proud of the accuracy and robustness of our models, as well as the potential impact our tool could have in preventing cyberbullying. We also developed a user-friendly interface for our tool, making it simple to integrate into existing social media platforms and messaging apps.
What we learned
Throughout this project, we learned about the complexities and nuances of working with natural language data, as well as the importance of high-quality data preprocessing. We also gained valuable experience in developing and evaluating machine learning models and learned how to present our findings in a way that's easy to understand for non-technical audiences.
What's next for Cyberbullying Prediction Using NLP
Looking forward, we plan to expand our tool to incorporate more advanced NLP techniques, such as sentiment analysis and topic modeling. We also hope to work with social media platforms to implement our solution on a larger scale and integrate it with existing content moderation systems. Ultimately, we believe that our tool can help make the online world a safer and more welcoming place for all.
