Abstract

We are presenting our practical experiences from using information retrieval (IR) as an extrinsic task for which, amongst many others, LDA can be applied (Wei et al., 2006). This allows us to use established evaluation metrics, precision and recall, in a realistic use case. We assume that a model that performs well on IR fits related tasks as well.
