Adapted Sentiment Similarity Seed Words For French Tweets' Polarity Classification

Abstract

We present, in this paper, our contribution in DEFT 2018 task 2 : ``Global polarity'', determining the overall polarity (Positive, Negative, Neutral or MixPosNeg) of tweets regarding public transport, in French language. Our system is based on a list of sentiment seed-words adapted for French public transport tweets. These seed-words are extracted from DEFT's training annotated dataset, and the sentiment relations between seed-words and other terms are captured by cosine measure of their word embeddings representations, using a French language word embeddings model of 683k words. Our semi-supervised system achieved an F1-measure equals to 0.64.
