Mohamed Morchid, Georges Linarès · 2012
Abstract. In this paper, we present a method of tweet contextualization by using a semantic space to extend the tweet vocabulary. This method is evaluated on the tweet contextualization benchmark. Contextualiza-tion is build with the sentences from English Wikipedia. The context is obtained by querying a baseline system of summary. The query is made with words from a semantic space that is estimated via a latent dirichlet allocation (LDA) algorithm. Our experiment demonstrate the effectiveness of the proposal.
