This paper proposes to apply the contin- uous vector representations of words for discovering keywords from a financial sen- timent lexicon. In order to capture more keywords, we also incorporate syntactic information into the Continuous Bag-of- Words (CBOW) model. Experimental re- sults on a task of financial risk prediction using the discovered keywords demonstrate that the proposed approach is good at pre- dicting financial risk.
