Transformer Language Models for UX Dimensions in VR Gaming

This repository contains seven fine-tuned transformer models for analyzing UX dimensions in virtual reality (VR) gaming. The models are based on RoBERTa-large [1] and were fine-tuned on 2,100 VR game reviews to classify sentiment across seven UX dimensions: Immersion, Presence, Achievement, Engagement, Embodiment, Physical Discomfort, and Controllability.

Each model assigns one of three possible sentiment labels to user reviews:
0 (neutral): The UX dimension is mentioned neutrally or not discussed.
1 (positive): The UX dimension is described positively.
2 (negative): The UX dimension is described negatively.

These models were developed as part of the research study:
Pasch, S., Lee, S., Cha, M.C. (2025). Exploring UX Dimensions and Experience-Levels in VR Gaming: Insights from Online Reviews using Transformer Models.
