Role of POS Tags in Abbreviation Detection

As far as i know,
POS tags provide syntactic context that helps distinguish abbreviations (often tagged as proper nouns or acronyms) from regular tokens. Leveraging POS features can:

• Improve precision by filtering out tokens that match acronym patterns but function differently in a sentence.
• Aid sequence models (like BiLSTMs or Transformers) in learning token dependencies, boosting recall for long-form spans.
