This paper describes the Duluth systems that participated in the Cross?Level Se- mantic Similarity task of SemEval?2014. These three systems were all unsupervised and relied on a dictionary melded together from various sources, and used first?order (Lesk) and second?order (Vector) over- laps to measure similarity. The first?order overlaps fared well according to Spear- man?s correlation (top 5) but less so rela- tive to Pearson?s. Most systems performed at comparable levels for both Spearman?s and Pearson?s measure, which suggests the Duluth approach is potentially unique among the participating systems.
