Interpreting Product Update as Reasoning about Observations and Meta-Observations
Jan Broersen · DROPS (Schloss Dagstuhl – Leibniz Center for Informatics) · 2009
In this brief note, I would like to suggest that it makes sense to reinterpret product update, as introduced by Baltag, Moss and Solecki, as a system to account for observations and metaobservations, where a meta-observation is an observation of an observation. Under this interpretation we also take products of action models with meta-action models. I deliberate on some possible consequences of this extension to the interpretation of product update.
