SpringerBriefs in Computer Science From Opinion Mining to Financial Argument Mining - Chung-Chi Chen Hen-Hsen Huang Hsin-Hsi Chen Kartoniert (TB)

Opinion mining is a prevalent research issue in many domains. In the financial domain however it is still in the early stages. Most of the researches on this topic only focus on the coarse-grained market sentiment analysis i.e. 2-way classification for bullish bearish. Thanks to the recent financial technology (FinTech) development some interdisciplinary researchers start to involve in the in-depth analysis of investors' opinions. These works indicate the trend toward fine-grained opinion mining in the financial domain. When expressing opinions in finance terms like bullish bearish often spring to mind. However the market sentiment of the financial instrument is just one type of opinion in the financial industry. Like other industries such as manufacturing and textiles the financial industry also has a large number of products. Financial services are also a major business for many financial companies especially in the context of the recent FinTech trend. For instance many commercial banks focus on loans and credit cards. Although there are a variety of issues that could be explored in the financial domain most researchers in the AI and NLP communities only focus on the market sentiment of the stock or foreign exchange. This open access book addresses several research issues that can broaden the research topics in the AI community. It also provides an overview of the status quo in fine-grained financial opinion mining to offer insights into the futures goals. For a better understanding of the past and the current research it also discusses the components of financial opinions one-by-one with the related works and highlights some possible research avenues providing a research agenda with both micro- and macro-views toward financial opinions.
