Conclusions
GEM Research helps GEM Users:
• Registries –a tool for catalogers (GEMCat) and educators (The Gateway).
• StandardConnection – help teachers find and retrieve resources correlated to content standards.
• Natural Language Processing & Machine Learning – ability to “scale-up” by automatic generation of metadata.
