WordNet-LMF

WordNet Lexical Markup Framework (LMF)

About

This is a Node.js Command-Line Interface (CLI) and underlying Application Programming Interface (API) for parsing WordNet-LMF XML format files and importing the data into compact SQLite database file.

The motivation for this approach is: a 100MB LMF XML consumes about 1GB of RAM (due to the XML DOM) and is very slow on querying, while the corresponding SQLite database file is just about 20% of the size of the LMF XML file and can be queried very fast and with harmless RAM consumption.

This NPM module comes with just the LMF CLI and API for processing LMF XML files and does not ship with any particular LMF XML files. See the companion modules wordnet-lmf-en and wordnet-lmf-de for English and German WordNets in LMF XML/SQLite format.

Data Model

Based on the WordNet-LMF XML DTD, we derived and documented the LMF Data Model we are using in this NPM module.

Installation

$ npm install wordnet-lmf

Command-Line Interface (CLI)

$ wordnet-lmf -d wordnet-lmf-en.db import -f easysax -e 2 wordnet-lmf-en.xml
$ wordnet-lmf -d wordnet-lmf-en.db query "SELECT * FROM Lemma WHERE writtenForm LIKE '%speaker%';"
