Experiments with Spectral Learning of Latent-Variable PCFGs
Latent-variable PCFGs (L-PCFGs) are highly successful model for natural languagea parsing. Recent work (Cohen et al., 2012) has introduced a spectral algorithm for param- eter estimation of L-PCFGs, which—unlike the …...
Coarse Lexical Frame Acquisition at the Syntax–Semantics Interface Using a Latent-Variable PCFG Model
AbstractWe present a method for unsupervised lexical frame acquisition at the syntax–semantics interface. Given a set of input strings derived from dependency parses, our method generates a set of clusters …...
