This paper describes the evaluation of differ- ent kinds of textual features for the Cross- Lingual Textual Entailment Task of SemEval 2013. We have counted the number of N - grams for three types of textual entities (char- acter, word and PoS tags) that exist in the pair of sentences from which we are inter- ested in determining the judgment of textual entailment. Difference, intersection and dis- tance (Euclidian, Manhattan and Jaccard) of N -grams were considered for constructing a feature vector which is further introduced in a support vector machine classifier which al- lows to construct a classification model. Five different runs were submitted, one of them considering voting system of the previous four approaches. The results obtained show a per- formance below the median of six tea...
