This paper describes the four systems RMIT fielded for the TREC 2016 LiveQA task and the associated experiments. Similar to last year, the results show that simple solutions tend to work best, and that our improved baseline systems achieved an above-average performance. We use a commercial search engine as a first stage retrieval mechanism and compare it with our internal system which uses a carefully curated document collection. Somewhat surprisingly, we found that on average the small curated collection performed better within our current framework, warranting further studies on when and when not to use an external resource, such as a publicly available search engine API. Finally, we show that small improvements to performance can substantially reduce failure rates.
