Offline etymological dictionary

It is not a real application, but a DEMO I prepared for one (unaccomplished) employment.

Introduction

Simple Python application for demonstration of typical processing of RDF data:

• data import
• standard (RDFS) and custom vocabularies
• RDF graph building
• storing data into Berkeley DB (Sleepycat)
• RDF graph querying (SPARQL)

Was created for demonstration of proof concept, but can be used for real inquiry of words' etymology:

> python ./dictionary.py --lang=eng scholar

Result:

scholar — English
 < scoler — Middle English (1100-1500)
  < scolere — Old English (ca. 450-1100)
   < scholaris — Latin
    < schola — Latin
     < σχολή — Ancient Greek (to 1453)
      < σχολεῖον — Ancient Greek (to 1453)

Pre-requisites

1. Install Python 3 libraries: rdflib, bsddb.

2. Download "Etymological Wordnet 2013-02-08" dataset extracted by Gerard de Melo from English Wiktionary (License: CC-BY-SA 3.0). Direct download link:

   etymwn-20130208.zip (26.2 Mb)

3. Extract zip-file into the project folder (etymological-dictionary/etymwn.tsv).

4. Run python ./import.py to import data into the internal database. It will take about 1 hour of time and 3.8 Gb of space.

Usage

Run dictionary.py with two parameters: a word and the corresponding ISO 639-3 language code:

> python ./dictionary.py --lang=eng muscular

To integrate the etymology dictionary into the GoldenDict application:

1. Open Edit|Dictionaries...

2. On the "Programs" tab add new item:

   • type: Plain text
   • command: python /path/to/dictionary.py --lang=eng %GDWORD%

3. Add the newly created source to your dictionary set on the "Groups" tab
