The CLARIN Language Resource Switchboard

The CLARIN infrastructure gives users access to an increasingly rich set of language-related resources,using the Virtual Language Observatory, the Federated Content Search, and the Virtual Collection Registry. While there is ample support for searching resources using metadata-based& search, or full-text search, or aggregating resources into virtual collections, there is little support for users to help them processing resources in one way or another. While there is a considerable number of processing software in the CLARIN world, there is no single point of access where users can find tools to fit their needs and the resource they have. In this paper, we present& the CLARIN Language Resource Switchboard (LRS), which aims at helping users to connect resources with the tools that can process them. The LRS lists all applicable tools for a given resource, lists the tasks the tools can achieve, and invokes the selected tool in such a way so that processing can start immediately without any or little prior tool parameterization.
