We describe refinements to hierarchical translation search procedures intended to reduce both search errors and memory us- age through modifications to hypothesis expansion in cube pruning and reductions in the size of the rule sets used in transla- tion. Rules are put into syntactic classes based on the number of non-terminals and the pattern, and various filtering strate- gies are then applied to assess the impact on translation speed and quality. Results are reported on the 2008 NIST Arabic-to- English evaluation task.
