| Challenge: | Word embeddings are the most popular input for many NLP tasks. |
| Approach: | They propose to use Greek word embeddings as an unsupervised learning tool . they use a Greek word analogy test set and a morphological test collection to evaluate word similarities . |
| Outcome: | The proposed model is able to create meaningful representations of Greek words . the proposed model can be adapted to Greek language and polysemy . |
