Financial Keyword Expansion via Continuous Word Vector Representations
Ming-Feng Tsai, Chuan‐Ju Wang · 2014
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. 1
