Most of this research is on sentiment analysis, but some of it has tried to use the news itself to predict market movements. In this paper, we use 10-years of news articles – from a weekly, agricultural, trade newspaper – to predict price changes in a commodity market for beef. Two experiments explore the different ways in which news reports affect the market via (i) major market-impacting events (i.e., rare natural disasters or food scandals) or (ii) minor market-impacting events (e.g., mundane reports about inflation, oil prices, etc). We find that different techniques need to be used to uncover major events (e.g., LLRs) as opposed to minor events (e.g., classifiers) and show that no single unified predictive model appears to be able to do both.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Keywords:||Event detection; Market prediction; Text analytics; News||Other versions:||http://www.saiconference.com/Conferences/IntelliSys2017||Language:||en||Status of Item:||Peer reviewed||Conference Details:||Intelligent Systems Conference 2017 (IntelliSys2017), London, United Kingdom, 7-8 September 2017|
