Learning Frame Embeddings

Replace the focus verb with its FrameNet frame label (either provided in the Gold data, or tagged via the parser), and train embedding models(word2vec skip-gram Glove, and Fast-Text) on the resulting data.
This yields joint embedding spaces that contain both common words and FrameNet frame embeddings.

Evaluation metrics:

  1. This lexical metric (lex) evaluates whether the frame embedding is similar to words within its frame and dissimilar to those without.
    lex(f)=wfcos(Ew,Ef)fwfkcos(Ew,Ef)klex(f) = \sum_{w\in f}\frac{cos(E_w, E_f)}{|f|} - \sum_{w\notin f}^{k}\frac{cos(E_w, E_f)}{|k|}
  2. The structural similarity metric str is evaluating whether the frame embeddings are more similar around their neighbors as FrameNet also contains linking relations between frames (eg. used-by, uses), yielding a hierarchy of connected frames.
    str(f)=nNcos(En,Ef)NnNkcos(En,Ef)kstr(f) = \sum_{n\in N}\frac{cos(E_n, E_f)}{|N|} - \sum_{n\notin N}^{k}\frac{cos(E_n, E_f)}{|k|}
