Out-Of-Vocabulary (OOV) Subword

A Out-Of-Vocabulary (OOV) Subword is a Subword Unit that does not appear in training subword vocabulary.

• AKA:Out-Of-Vocabulary (OOV) Subtoken.
• Context:
  • It can be model by Out-Of-Vocabulary (OOV) Subword Modeling Task.
• Example(s):
  • a subword that has not been seen during training.
  • a subtoken that has not been seen during training.
  • an Out-Of-Vocabulary (OOV) Symbol.
  • a Out-Of-Vocabulary (OOV) Character.
• Example(s):
  • an Out-Of-Vocabulary (OOV) Word.
  • an In-Vocabulary Word.
• See: Word Segmentation System, Subword Embedding, Vocabulary Word, Lexicon Word, Abbreviated Word, Unsupervised Transliteration Model, Lexical Normalization Task.
