GF 3.8 Release Notes
|
|
June 2016
|
|
|
|
==Installation==
|
|
|
|
See the [download page http://www.grammaticalframework.org/download/index.html].
|
|
|
|
|
|
==What's new==
|
|
|
|
Roughly 400 changes have been pushed to the source repository since
|
|
[the release of GF 3.7.1 release-3.7.1.html] in October 2015.
|
|
|
|
|
|
===GF compiler and run-time library===
|
|
|
|
|
|
====New features and notable changes====
|
|
|
|
- GF shell: ``vd`` can now output
|
|
[universal dependency http://universaldependencies.org/] diagrams
|
|
in various formats, see ``help vd``.
|
|
- The C runtime now includes an experimental library for managing
|
|
and querying ontologies built on top of the abstract syntax of
|
|
a grammar. Since the ontology is based on an abstract syntax,
|
|
it is language independent by design. For now the library is
|
|
only used in the GF Offline Translator. The library uses
|
|
the B-tree backend of [SQLite https://www.sqlite.org/]
|
|
which makes it scalable even for non-trivial ontologies.
|
|
|
|
|
|
====Other changes and bug fixes====
|
|
|
|
- GF shell: a simple post-processing step has been added in the ``cc`` command
|
|
to try compute ``pre{...}`` tokens instead of leaving them uninterpreted.
|
|
- GF shell: an argument parsing problem has been fixed in the ``cc`` command.
|
|
The problem was introduced before the release of GF 3.7.1 and prevented
|
|
commands like ``cc "last"`` and ``cc "last"++"year"`` from working,
|
|
but they should work again now.
|
|
- Python binding: with the OS X installer package (``gf-3.8.pkg``),
|
|
the Python binding should now work directly out of the package.
|
|
(The installer puts the modules under ``/Library/Python/2.7/site-packages``,
|
|
where the Python interpreter can find them.)
|
|
- Various improvements and bug fixes in the C run-time system and its bindings
|
|
to other languages.
|
|
|
|
|
|
====Changes of interest to compiler developers====
|
|
|
|
- The compiler source code has been updated for compatibility with GHC 8.0.1.
|
|
|
|
|
|
===Resource Grammar Library===
|
|
|
|
- New languages:
|
|
- Nynorsk by Stian Rødven Eide (fairly complete, supports API)
|
|
- Ancient Greek by Hans Leiß (partial, no API yet)
|
|
- Slovene by Krasimir Angelov (partial, no API yet, donated by [Digital Grammars http://www.digitalgrammars.com/])
|
|
|
|
- Various fixes for several languages.
|
|
- English and Scandinavian: relative clauses and slash questions have been modernized to
|
|
using preposition stranding by default. This also enables the use of //that// in English,
|
|
which solves a problem of choosing between //which// and //who// when animacy information
|
|
is not available. The previous defaults (//which//,//who//,//whom//, pied piping) are available
|
|
in ``Extra`` modules.
|
|
|
|
- Numerous fixes in the translation dictionaries.
|
|
- two new wide-coverage languages: Estonian and Russian
|
|
- The abstract syntax of the translation dictionary is now annotated
|
|
with glosses, examples and sense IDs from WordNet. This gives us
|
|
a basis on how to choose the best translations for different languages.
|
|
- We have started splitting many of the lexical entries in the abstract
|
|
syntax of the dictionary into different entries for senses that
|
|
translate differently accross languages.
|
|
|
|
|
|
===Apps and Cloud services===
|
|
|
|
- GF Offline Translator (for Android) now includes a user interface similar
|
|
to the Phrasomatic. This lets the user explore the controlled
|
|
language fragment of the wide coverage grammar. Althought
|
|
the code is already there, the new release of the app
|
|
will be postponed to get some of its other features stable.
|
|
- GF Offline Translator (for Android) now offers glosses and examples for
|
|
most of its lexical items. This means that now it can be used as a more
|
|
explanatory dictionary.
|
|
- Minibar can now show universal dependency diagrams for grammars that
|
|
support it (e.g. the ResourceDemo grammar).
|
|
- PGF service: there is a new command ``deptree`` that can output
|
|
universal dependency diagrams for grammars that support it (there
|
|
has to be a label configuration file).
|
|
- Wide Coverage Translation Demo:
|
|
there is now a new button "Grammars..." which show a list where users can
|
|
select which application grammars to use for translation, in addition to
|
|
the wide coverage grammar. Application grammars can give higher quality
|
|
translations in the domain they cover.
|
|
You can change the order in which the selected grammars are tried
|
|
by dragging them up and down in the list.
