This website presents a proof-of-concept search engine system for accessing chemical data from the World Avatar Knowledge Graph and the Wikidata Knowledge Graph. The Knowledge Graphs offers inter-connected data from chemical kinetics to chemical and physical properties of species and many other domains. We trained a question type classification model and an entity extraction model to interpret chemistry-related questions of interest. The system has a novel design which applies a topic model to identify the question-to-ontology affiliation to improve its accuracy.

To use the Marie search engine, type a question into the field below, or select one of the provided sample questions.
