Linguistic Type Data-Base

The Linguistic Type Database (LTDB, née Lextype DB), describes types and rules of a DELPH-IN grammar with frequency information from the treebank. Lexical types can be seen as detailed parts-of-speech. Information about the types are constructed from the linguists documentation in the grammar, a kind of literate programming.

There is more documentation at the DELPH-IN Wiki.

Usage

1. Run ./make-ltdb.bash --grmdir /path/to/grammar

./make-ltdb.bash --grmdir ~/logon/dfki/jacy

Everything is installed to ~/public_html/

Installation

Requirements

* python 2.7, python 3, pydelphin, docutils, lxml
* Perl
* SQLite3
* Apache
* LKB/Lisp        for db dump
* xmlstarlet      for validating lisp

We prefer that Sentence IDs are unique, if we see two sentences in the gold treebank with the same ID, we only store the first one.

Only the new LKB-FOS (http://moin.delph-in.net/LkbFos) suppoorts the new docstring comments. We assume it is installed in LKBFOS=~/delphin/lkb_fos/lkb.linux_x86_64.

Install dependencies (in ubuntu):

sudo apt-get install apache2 xmlstarlet
sudo apt-get install python-docutils python3-docutils python3-lxml

sudo pip install pydelphin --upgrade
sudo pip3 install pydelphin --upgrade

Enable local directories in Apache2

This may be different on different operating systems

sudo a2enmod userdir
sudo a2enmod cgi

Put this in /etc/apache2/sites-available/000-default.conf

<Directory /home/*/public_html/cgi-bin/>
   Options +ExecCGI
   AddHandler cgi-script .cgi
</Directory>

And then restart Apache2

sudo service apache2 restart

You may have to change the path to the LKB inside make-ltdb.bash

LKBFOS=~/delphin/lkb_fos/lkb.linux_x86_64

Trouble Shooting

If the LKB complains

error finding frame source: Bogus form-number: ....

it probably means you have a docstring in an instance file, or an old version of the LKB. Make sure you only document types for now.

Todo

• check I am getting lrule/irule right
