Exporting Trees

You can output treebankied data in other formats with Trees | Export. This outputs the data in one gzipped file per tree.

If you set the switch to thinning normalize, the system only outputs results for selected trees (Trees | Export | Thinning Export or (setf tsdb::*redwoods-thinning-export-p* t)).

• Possible output formats are: tree, derivation, avm, mrs, rmrs.

• derivation---derivation tree: primary, labeled in terms of grammar-internal identifiers;

• tree---phrase structure tree: derived, labeled using a set of abbreviatory symbols;

• avm---attibute value matrix: derived, the full HPSG sign, including all daughters;

• mrs---MRS: meaning representation, raw;

• indexed---MRS: indexed;

• prolog---MRS: prolog style;

• rmrs---Robust MRS: meaning representation as RMRS;

• xml---Robust MRS: formatted with XML;

• dependencies---dependencies: derived, elementary dependency relations (reduced form of MRS);

• all---All the representations.

You can set what information gets output in '.tsdbrc' (ItsdbCustomization).

(setf *redwoods-export-values* '(:derivation :tree :mrs :prolog))

Note: Some of these data structures may require reconstruction. In this case you need to have the same version of the grammar loaded (in the LKB) that was used to parse the profile.

Exporting can be memory intensive. Use a batch instead for large profiles. There is an example described on RedwoodsTop.
