Multilingual replication of PACE

Conduct a multilingual replication of the PACE evaluation to assess whether its results transfer beyond the Chinese-language sales-register setting.

Background

The evaluation is centered on a single automotive-sales vertical, and the paper notes that both the volatility prior and filler prompt are Chinese-language sales-register artifacts. Although the volatility prior is described as a replaceable plug-in, transfer to multilingual deployments has not been established by the reported experiments. A multilingual replication is therefore identified as unresolved.

References

The evaluation centers on a single vertical: the DuReader transfer check is retrieval-friendly by construction, and the volatility prior and filler prompt are Chinese-language sales-register artifacts (the prior is a replaceable plug-in, so transfer requires swapping the classifier, not the mechanism); a multilingual replication remains open.
