This paper of Yuret's http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.129.5016&rep=rep1&type=pdf cites 53% accuracy compared against "dependency parses derived from dependency-grammar-izing Penn Treebank parses on WSJ text" .... It was written after his PhD thesis. Is there more recent work by Yuret that gives massively better results? If so I haven't seen it. Spitkovsky's more recent work on unsupervised grammar induction seems to have gotten better statistics than this, but it used radically different methods. > > a) Seemingly "worse than LG-English" "sequential parses" provide seemingly > better "LG grammar" - that may be some mistake, so we will have to > double-check this. > Anton -- Have you looked at the inferred grammar for this case, to see how much sense it makes conceptually? Using sequential parses is basically just using co-occurrence rather than syntactic information I wonder what would happen if you used *both* the sequential parse *and* some fancier hierarchical parse as inputs to clustering and grammar learning? I.e. don't throw out the information of simple before-and-after co-occurrence, but augment it with information from the statistically inferred dependency parse tree... -- Ben -- You received this message because you are subscribed to the Google Groups "opencog" group.
