This paper describes the system used by the LIPN team in the task 10, Multilin- gual Semantic Textual Similarity, at Sem- Eval 2014, in both the English and Span- ish sub-tasks. The system uses a sup- port vector regression model, combining different text similarity measures as fea- tures. With respect to our 2013 partici- pation, we included a new feature to take into account the geographical context and a new semantic distance based on the Bhattacharyya distance calculated on co- occurrence distributions derived from the Spanish Google Books n-grams dataset.
