Marie is a Question Answering system designed specifically for chemistry. It employs a text-to-text pre-trained language model, the fine-tuned Flan-T5 model, enabling it to directly translate natural language questions into SPARQL queries, bypassing the need for separate entity and relation linking components. Its primary data source is the chemistry domain of 'The World Avatar' (TWA), a dynamic knowledge graph which contains detailed information on chemical species, their properties, applications, and classifications. Marie stands out in its ability to provide precise answers to complex queries, even those that involve numerous relation hops. The system ensures a balance between accuracy and speed and boasts impressive flexibility, allowing it to adapt to the evolving TWA knowledge graph without the necessity of constant retraining.
