Fusing Document, Collection and Label Graph-based Representations with Word Embeddings for Text Classification

1 code implementation • WS 2018 • Konstantinos Skianis, Fragkiskos Malliaros, Michalis Vazirgiannis

Contrary to the traditional Bag-of-Words approach, we consider the Graph-of-Words(GoW) model in which each document is represented by a graph that encodes relationships between the different terms.
