Fine-grained analysis of explicit and implicit sentiment in financial news articles

作者:

Highlights:

• In the financial domain, news has an impact on the stock markets.

• Most sentiment analysis methods are coarse-grained and focus on explicit sentiment.

• Such a method is insufficient to detect topic-specific sentiment in financial news articles.

• We propose a novel fine-grained method that detects explicit and implicit sentiment.

• This is a viable method for topic-specific sentiment analysis in financial news text.
