Textual Deconvolution Saliency (TDS) : a deep tool box for linguistic analysis

Laurent Vanni, MĂ©lanie Ducoffe, Carlos Aguilar, Frederic Precioso, Damon Mayaffre

In this paper, we propose a new strategy, called Text Deconvolution Saliency (TDS), to visualize linguistic information detected by a CNN for text classification. We extend Deconvolution Networks to text in order to present a new perspective on text analysis to the linguistic community. We empirically demonstrated the efficiency of our Text Deconvolution Saliency on corpora from three different languages: English, French, and Latin. For every tested dataset, our Text Deconvolution Saliency automatically encodes complex linguistic patterns based on co-occurrences and possibly on grammatical and syntax analysis.
