N2 - The CLARIN-DK infrastructure is not only a repository of resources, but also a place where users can analyse, annotate, reformat and potentially even translate resources, using tools that are integrated in the infrastructure as web services. In many cases a single tool does not produce the desired output, given the input resource at hand. Still, in such cases it may be possible to reach the set goal by chaining a number of tools. The approach presented here frees the user of having to meddle with tools and the construction of workflows. Instead, the user only needs to supply the workflow manager with the features that describe her goal, because the workflow manager not only executes chains of tools in a workflow, but also takes care of autonomously devising workflows that serve the user’s intention, given the tools that currently are integrated in the infrastructure as web services. To do this, the workflow manager needs stringent and complete information about each integrated tool. We discuss how such information is structured in CLARIN-DK. Provided that many tools are made available to and through the CLARIN-DK infrastructure, the automatically created workflows, although simple linear programs without branching or looping constructs, can cover a large swath of users’ needs. It is rewarding for both users and tool developers that the infrastructure takes advantage of new tools from the moment they are registered, because there is no need to wait for human expert users to construct and save for later use workflows that incorporate new tools.
