  abstract  = {We present an approach to mathematical information retrieval (MIR) that
	exploits a special kind of technical terminology, referred to as a
	mathematical type. In this paper, we present and evaluate a type
	detection mechanism and show its positive effect on the retrieval of
	research-level mathematics. Our best model, which performs query expansion with
	a type-aware embedding space, strongly outperforms standard IR models with
	state-of-the-art query expansion (vector space-based and language
	modelling-based), on a relatively new corpus of research-level queries.},
