This paper presents three systems for semantic textual similarity (STS) evaluation at SemEval-2017 STS task.One is an unsupervised system and the other two are supervised systems which simply employ the unsupervised one.All our systems mainly depend on the semantic information space (SIS), which is constructed based on the semantic hierarchical taxonomy in WordNet, to compute non-overlapping information content (IC) of sentences.Our team ranked 2nd among 31 participating teams by the primary score of Pearson correlation coefficient (PCC) mean of 7 tracks and achieved the best performance on Track 1 (AR-AR) dataset.
