text: This paper introduces a new exploration policy for Reinforcement Learning for agents on the web called "Workflow Guided Exploration". Workflows are defined through a DSL unique to the domain. The paper is clear, very well written, and well-motivated. Exploration is still a challenging problem for RL. The workflows remind me of options though in this paper they appear to be hand-crafted. In that sense, I wonder if this has been done before in another domain. The results suggest that WGE sometimes helps but not consistently. While the experiments show that DOMNET improves over Shi et al, that could be explained as not having to train on raw pixels or not enough episodes.
