Glossary

This is a collection of terms related to the MAYZ Toolkit.

maximum entropy (ME) model

A probabilistic model. For details, see Amis Home Page.

derivation (specific usage in MAYZ)

A tree structure representing a syntactic structure conforming to the target grammar theory. In addition to phrase information, it includes information about applied schemas. For example, in HPSG, it corresponds to a sign includes daughter structures, and in CCG, it corresponds to a derivation tree. In LTAG, it corresponds to a derived tree annotated with substitution/adjunction labels.

derivbank (specific to MAYZ)

A collection of derivations. In MAYZ, it is created semi-automatically by converting a treebank.

lexbank (specific to MAYZ)

A collection of terminals of derivations. It can be used to collect lexical information.

treebank

A collection of sentences annotated with CFG-style phrase structures. Various treebanks, e.g. Penn Treebank, have been produced. The aim of the development with the MAYZ toolkit is to make a derivbank from a treebank.

parse tree (specific usage in MAYZ)

In the MAYZ toolkit, trees in an input treebank are called "parse tree". Pharse structures in the target grammar theory are called "derivation".
