We collect the real-time textual information from Twitter, and convert it into five kinds of OIs, including the support price level, resistance price level, price target, buy-side cost, and sell-side cost. The OIs for all component stocks in Dow Jones Industrial Average Index (DJI) are provided, and shown with the real-time stock price for comparison and analysis. The information embedding in the OIs and the application scenarios are introduced.","doi":"10.24963/ijcai.2019/936","url":"https://ijcai.org/proceedings/2019/936","pdf":"https://ijcai.org/proceedings/2019/0936.pdf","markdown":"https://ijcai.org/proceedings/2019/936.md","bibtex":"https://ijcai.org/proceedings/2019/bibtex/936","volume":{"slug":"2019","title":"Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2019","url":"https://ijcai.org/proceedings/2019/","year":2019,"location":"Macao","dates":"10-16 August 2019","editors":"Sarit Kraus","isbn":"978-0-9992411-4-1","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2019"},"section":"Demos","track":"Demos","number":936,"pages":{"first":6500,"last":6502},"keywords":["AI: Natural Language Processing","Applications: Finance"],"videos":[],"references":[{"position":1,"raw":"[Behrendt and Schmidt, 2018] Simon Behrendt and Alexan- der Schmidt.
