Implementation of a Workflow Management System for Non-Expert Users

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedings

In the Danish CLARIN-DK infrastructure, chaining language technology (LT) tools into a workflow is easy even for a non-expert user, because she only needs to specify the input and the desired output of the workflow. With this information and the registered input and output profiles of the available tools, the CLARIN-DK workflow management system (WMS) computes combinations of tools that will give the desired result. This advanced functionality was originally not envisaged, but came within reach by writing the WMS partly in Java and partly in a programming language for symbolic computation, Bracmat. Handling LT tool profiles, including the computation of workflows, is easier with Bracmat's language constructs for tree pattern matching and tree construction than with the language constructs offered by mainstream programming languages.
