Experience

SemEval-2017 Task 6: #RankingHumorIn4Pages

In a team of six, we built a system that compares and ranks tweets based on their humor. This paper describes our system for humor ranking in tweets within the SemEval 2017 competition.

I worked on parameter tuning and created features that contributed the most to our sarcasm detection and ranking. We ranked second among ten submissions in Subtask A and second among nine submissions in Subtask B.

Third Place at AI Battleground

We placed third in a team hackathon competition to make the best AI-supported bot in 20 hours, which would play against other bots in the arena.

Notary Web aAplication

I built an enterprise web application using Java with Spring and the Vaadin framework. It is the official web application used by all notaries in Croatia.

Egrader

I developed a web application that grades essays written in English using grammar and content categories. This was done for a master project course. The models that calculate scores are trained using deep-learning techniques.
