Splits for the Ben-Mordecai and Elhadad Hebrew NER Corpus (BMC)

In order to evaluate performance in accordance with the original Ben-Mordecai and Elhadad (2005) work, we provide three 75%-25% random splits.

• Only the 7 entity categories viable for evaluation were kept (DATE, LOC, MONEY, ORG, PER, PERCENT, TIME) --- all MISC entities were filtered out.
• Sequence label scheme was changed from IOB to BIOES
• The dev sets are 10% taken out of the 75%
