Flair Word Embedding System

A Flair Word Embedding System is a Character-level Embedding System that creates contextual string embeddings by modeling words as sequences of characters.

• Context:
  • It was first introduced by Akbik et al. (2018).
  • GitHub repositories:
    • https://github.com/zalandoresearch/flair
    • https://github.com/flairNLP/flair
  • It uses a Character-level Language Model and a Sequence tagging model.
• Example(s):
