RESEARCH STORY

During my master’s thesis research in physics on the topic “Simulation and Visualization of Gravitational Waves from Binary Black Holes” at the University of Konstanz, I realized the current need for effective tools to process mathematical formulas in document analysis and Mathematical Information Retrieval (MathIR).

Since then, I review, develop, and evaluate Mathematical Entity Linking (MathEL) methods and applications. Methods include STEM document (formula & identifier) annotation recommendation, formula concept retrieval (classification & clustering), and nearest-neighbor retrieval. Applications include mathematical (STEM) document classification & clustering, Wikipage readability & accessibility, formula search, question answering, and question generation. Particularly, I am focused on the Wikidata knowledge graph.
