This paper presents our approach to se- mantic relatedness and textual entailment subtasks organized as task 1 in SemEval 2014. Specifically, we address two ques- tions: (1) Can we solve these two sub- tasks together? (2) Are features proposed for textual entailment task still effective for semantic relatedness task? To address them, we extracted seven types of features including text difference measures pro- posed in entailment judgement subtask, as well as common text similarity measures used in both subtasks. Then we exploited the same feature set to solve the both sub- tasks by considering them as a regression and a classification task respectively and performed a study of influence of differ- ent features. We achieved the first and the second rank for relatedness and entailment task r...
