JUST-OS Chatbot

    The JUST-OS (Judicious User-friendly Support Tool for Open Science) chatbot is an initiative by researchers at the University of Groningen and FORRT that aims to develop an AI-based chatbot to help researchers navigate Open Science resources more easily.

    Researchers generally support Open Science practices but often struggle navigating the vast landscape of available resources. JUST-OS aims to provide user-friendly, tailored, and efficient guidance to help researchers find relevant Open Science resources.
