ABSTRACT
In the formal large-scale test, such as national certification tests, parallel test sheets must be composed at the same time to handle emergency event or prevent cheating. Parallel test sheets are a set of test sheets generated according to similar test specifications, which not only paralleled in content but also paralleled in structure. Recently, as the eciency and eectiveness of computer-based test sheet generation have been confirmed by many early studies, automatic generation of parallel test sheets attracts the attention of many scholars.
