Cross-period (diachronic) thesaurus construction aims to enable potential users to
search for modern terms and obtain semantically related terms from earlier periods in history. This is a complex task not previously addressed computationally. In
this paper we introduce a semi-automatic iterative Query Expansion (QE) scheme
for supporting cross-period thesaurus construction. We demonstrate the empirical
benefit of our scheme for a Jewish crossperiod thesaurus and evaluate its impact on
recall and on the effectiveness of lexicographer manual effort
