Text Categorization Using Predicate-Argument Structures
Jacob Persson, Richard Johansson, Pierre Nugues · DSpace repository (University of Tartu) · 2009
Most text categorization methods use the vector space model in combination with a representation of documents based on bags of words.As its name indicates, bags of words ignore possible structures in the text and only take into account isolated, unrelated words.Although this limitation is widely acknowledged, most previous attempts to extend the bag-of-words model with more advanced approaches failed to produce conclusive improvements.
