Applications and Tools

How do I access the data?

Once you have signed the licence, you will get the data distribution as an archive, typically sent as an e-mail attachment. The data are available in XML and as a database dump. We offer several tools and application programming interfaces with which this data can be accessed.



Application Programming Interfaces

There are several Application Programming Interfaces (API) available for Java and for Perl. These APIs provide easy access to all information in GermaNet. All APIs reflect the structure of GermaNet, but not all reflect the newest version of GermaNet. You get all APIs for free, but you are kindly requested to report bugs to the developers.




Semantic Relatedness API

To calculate semantic relatedness between any two words/readings in GermaNet, you can use the Semantic Relatedness API implemented in Java:




GermaNet-Explorer

GermaNet-Explorer is a software to visualize GermaNet. It allows to show all lexical units (word senses) and synsets of a word. Furthermore, it can represent all semantic relations in a structured manner. A visual graph-based navigation through GermaNet is possible.



This software was originally developed in the context of the project "Hypertextualisierung auf textgrammatischer Grundlage" (HyTex) at the University of Dortmund. You can find further documentation on the project page. GermaNet-Explorer was programmed by Marc Finthammer, University of Dortmund, and adapted to the new Java API 2.0 (see above) by Verena Henrich, University of Tübingen.



GernEdiT - The GermaNet Editing Tool

GernEdiT is a graphical editor that is used by the lexicographers to enter lexicographic data into the GermaNet database. It provides a graphical user interface to the database, which mainly allows maintaining the GermaNet data in a user-friendly way. There are several ways to search data, and browse through the GermaNet graph. These functionalities support lexicographers, among other things, in finding the appropriate place in the hierarchy for the insertion of new synsets and lexical units. A screenshot of GernEdiT is shown in Figure 1. GernEdiT is freely available for download:



Some flash movies show GernEdiT in action:


  • GernEdiT flash movie 1: Basic search functionality, conceptual relations list, hypernymy graph, frames and examples, view editing history with its filtering functionality, list with all lexical units

  • GernEdiT flash movie 2: Add new conceptual relation, delete conceptual relation, follow conceptual relation, list with all synsets with its search and filter functionalities

  • GernEdiT flash movie 3: Insert new synset with lexical unit, insert new lexical unit, delete lexical unit, delete synset

XQuery Scripts to Convert GermaNet into Wordnet-LMF

There are two XQuery scripts for converting GermaNet to Wordnet-LMF available (see page on Wordnet-LMF for further details):
