Distributed structures and distributional meaning
Fabio Massimo Zanzotto, Lorenzo Dell’Arciprete · 2011
Stemming from distributed representation theories, we investigate the interaction between distributed structure and distributional meaning. We propose a pure distributed tree (DT) and distributional distributed tree (DDT). DTs and DDTs are exploited for defining distributed tree kernels (DTKs) and distributional distributed tree kernels (DDTKs). We compare DTKs and DDTKs in two tasks: approximating tree kernels TK (Collins and Duffy, 2002); performing textual entailment recognition (RTE). Results show that DTKs correlate with TKs and perform in RTE better than DDTKs. Then, including distributional vectors in distributed structures is a very difficult task. 1
