FBK-HLT: A New Framework for Semantic Textual Similarity
Ngoc Phuoc An Vo, Simone Magnolini, Octavian Popescu · 2015
This paper reports the description and performance of our system, FBK-HLT, participating in the SemEval 2015, Task #2 "Semantic Textual Similarity", English subtask.We submitted three runs with different hypothesis in combining typical features (lexical similarity, string similarity, word n-grams, etc) with syntactic structure features, resulting in different sets of features.The results evaluated on both STS 2014 and 2015 datasets prove our hypothesis of building a STS system taking into consideration of syntactic information.We outperform the best system on STS 2014 datasets and achieve a very competitive result to the best system on STS 2015 datasets.
