Converting a Toolbox lexical database to LKB format

Summary

Note: Update in progress as of October / November 2012. Hannes Hirzel

The LKB system (Linguistic Knowledge Builder) is a grammar and lexicon development environment for unification-based linguistic formalisms. LKB is focused on the use of HPSG. This page contains a description and the program to convert a lexicon database made with Toolbox to lexicon format needed by LKB. The scripts were developed by Hannes Hirzel.

A presentation in Trondheim, 2005 (File:Toolbox-LKB-Link-slides - version 4.pdf) shows how this was applied to a lexicon file of the Ga language edited by Mary E. Kropp Dakubu.

The scripting language used is called 'Consistent changes' and built into the Toolbox program. You may run the program from within Toolbox. To do so make the lexicon file the active windows and then choose the

  • 'File' menu,
  • 'Export'
  • 'TBox-LKB-Step1'.

This runs all processing steps. The result is a lexicon file in LKB format.

A working portable setup is available from the author on request. However the information and files to recreate the setup is included on this page. You might need to adapt it to your particular lexicon file.

Implementation

Description of the setup

The files which belong to a Toolbox project may be kept all in the same folder. The following screen shot shows the setup how Toolbox was setup to produce an LKB TDL lexicon file.



The folder 'Settings' contains the Toolbox exe file. Double click on it to start it.

Download

The following folder File:Toolbox Project Ga.zip contains the standard files produced by the utility program 'Toolbox New Project Package 1.5.8 from http://www'.sil.org/computing/toolbox/downloads.htm .


The file 'Dictionary.txt' has been replaced by the Ga lexicon created by Mary Ester Dakubu (MED), University of Ghana.


There is a folder 'Tbox2LKB-conv-scripts' which has a copy of the the cct files of the folder 2005-05-31Ga-for-LKB-Uni-Trondheim-11a

These cct files are used to convert the Ga lexicon which is in SFM (Toolbox format) to the format LKB (Linguistic Knowledge Builder) needs.


To run the conversion do the following steps

  1. Make the dictionary window the 'active window' by clicking on the title bar
  2. Choose menu 'File' / 'Export'
  3. Select 'TBox-LKB Step1'
  4. Click 'OK'.
  5. A new file 'LKBlexicon.tdl' is created.
