Implication

Benchmark evaluation demonstrates improved cross-domain named entity recognition in specialized domains, indicating that targeted pre-training strategies outperform standard baselines.

Key Points

To establish a comprehensive evaluation benchmark and determine effective domain-adaptive pre-training strategies for cross-domain named entity recognition across specialized target domains.
Constructed CrossNER, a fully labeled dataset spanning five distinct domains featuring specialized entity categories.
Curated domain-related text corpora to evaluate continuous domain-adaptive pre-training with varying corpus fractions and pre-training objectives.
Pre-training language models on fractional corpora enriched with domain-specialized entities consistently outperformed existing cross-domain baselines.
Employing more challenging pre-training objectives during domain adaptation yielded superior cross-domain entity extraction compared to standard pre-training strategies.
