Language Resource Switchboard

‌ Go to the Switchboard


The Language Resource Switchboard is a tool that helps you to find a matching language processing web application for your data. After uploading a file or entering a URL, you can select which task to perform. The Switchboard will then provide you with a list of available CLARIN tools to analyse the input.


There are also other ways of invoking the Switchboard:

  • Choose a file from the Virtual Language Observatory and have it analysed
  • Upload a file to B2DROP and start the Switchboard from there

Other ways of using CLARIN tools

The Switchboard is not the only way to use CLARIN tools. If you want to process multiple files, large data sets, or if you are a developer and you want to call a CLARIN service via an API, there are other ways of using CLARIN tools and services. You can find some examples below.

Webservice orchestration engines

  • Weblicht: an execution environment for automatic annotation of text corpora, built by CLARIN-D. Linguistic tools such as tokenisers, part of speech taggers, and parsers are encapsulated as web services, which can be combined by the user into custom processing chains. The resulting annotations can then be visualised in an appropriate way, such as in a table or tree format.
