LIM-LIG at SemEval-2017 Task1: Enhancing the Semantic Similarity for Arabic Sentences with Vectors Weighting
El Moatez Billah Nagoudi, Jérémy Ferrero, Didier Schwab · 2017
This article describes our proposed system named LIM-LIG.This system is designed for SemEval 2017 Task1: Semantic Textual Similarity (Track1).LIM-LIG proposes an innovative enhancement to word embedding-based model devoted to measure the semantic similarity in Arabic sentences.The main idea is to exploit the word representations as vectors in a multidimensional space to capture the semantic and syntactic properties of words.IDF weighting and Part-of-Speech tagging are applied on the examined sentences to support the identification of words that are highly descriptive in each sentence.LIM-LIG system achieves a Pearsons correlation of 0.74633, ranking 2nd among all participants in the Arabic monolingual pairs STS task organized within the Se-mEval 2017 evaluation campaign.
