The Syntax of Semantic Relations in Italian
Fabio Celli · 2009
The experiment reported in this paper is a feature engeneering op-eration that explores the syntactic structures of three different semantic relation types with tree kernels. This is done in order to find whether syntax can be a good feature to improve semantic relation separability in classification tasks. The average accuracy obtained is 63.09 %. 1 Introduction And related work In a previous experiment [1] it was found that three semantic relation classes (”role”, ”location”, ”social”) yielded better results in a classification task with respect to the seven semantic relation classes in ACE 2004 (see [3]), since those three classes are easily separable. The three semantic relations are: Role (entity
