LIPN: Introducing a new Geographical Context Similarity Measure and a Statistical Similarity Measure Based on the Bhattacharyya Coefficient

摘要

This paper describes the system used by the LIPN team in the task 10, Multilingual Semantic Textual Similarity, at SemEval 2014, in both the English and Spanish sub-tasks. The system uses a support vector regression model, combining different text similarity measures as features. With respect to our 2013 participation, we included a new feature to take into account the geographical context and a new semantic distance based on the Bhattacharyya distance calculated on cooccurrence distributions derived from the Spanish Google Books n-grams dataset.
