... clutter, for the filter f-score measure we use the maximum recall (MR) baseline rather than the minimum length (ML) baseline, since the former outperforms the lat- ter. Thus, ML is only shown for the ... from different domains. For a test setting used by previous work, we show an error reduction of 31% as opposed to their 20%. 1 Introduction Many algorithms for major NLP applications s...
