FCS Clarin endpoint

Overview

This is an endpoint for Federated Content Search (FCS).

There are many linguistic corpora online. They are available under different platforms and use a variety of query languages. FCS is a mechanism that allows you to search in multiple corpora at once, using simple text queries or a CQL-like language. This way, you can discover or compare corpora that can be useful for your research, after which you can proceed to them. This is done through the Aggregator.

An endpoint is a piece of software that serves as an intermediary between FCS and individual corpora. It translates the FCS requests into corpus-specific query languages, waits for the results, and then renders them in an XML format required by the FCS.

Different corpus platforms or online databases require different endpoints. This endpoint works with the following platforms or resources:

• ANNIS
• Tsakorpus
• Database of the Formulae-Litterae-Chartae project
