Evaluating Assistance of Natural Language Policy Authoring

The goal of the research study reported here was to investigate policy
authors’ ability to take descriptions of changes to policy situations
and author high-quality, complete policy rules that would parse with
high accuracy. As a part of this research, we investigated ways in
which we could assist policy authors in writing policies. This paper
presents the results of a user study on the effectiveness of providing
syntax highlighting in a natural language policy authoring interface.
While subjects liked the new interface, they showed no improvement in
accuracy when writing rules. We discuss our results in terms of a
three phase authoring process that users move through when authoring
or modifying policies. We describe this process, discuss why and how
our interface failed to support it and make recommendations to
designers on how to better support this process.
