Text Classification for Intelligent Portfolio Management
Young‐Woo Seo, Joseph Andrew Giampapa, Katia P. Sycara · 2002
In the application domain of stock portfolio management, software agents that evaluate the risks associated with the individual companies of a portfolio should be able to read electronic news articles that are written to give investors an indication of the financial outlook of a company. There is a positive correlation between news reports on a company's financial outlook and the company's attractiveness as an investment. However, because of the volume of such reports, it is impossible for financial analysts or investors to track and read each one. Therefore, it would be very helpful to have a system that automatically classifies news reports that reflect positively or negatively on a company's financial outlook. To accomplish this task, we treat the understanding of news articles as a text classification problem. In this paper, we propose a text classification method that we call, "Domain Experts" and "Self-Confident" sampling, and compare it with naive Bayes with expectation maximization (EM).
