Text classification with a Primal SVM endowed with domain knowledge

(2008) Technical Report. Unpublished, London, UK.


In this paper we solve a document classification task by incorporating prior/domain knowledge onto the SVM. The algorithm consists in to learn a prior classifier in the primal space (words) from an `external' source of information to the text classification itself: patterns of reader's eyes movements when reading relevant words for discriminating texts. This prior weight vector is then plugged into the SVM optimisation in the primal space. Experimental results include a comparison of the proposed algorithm with plain SVM classifiers and with an alternative way of mixing textual and eye information based on the SVM-2K.
