Abstract

The modeling and analysis of information flow from various sources (e.g., analyst reports, news, and social media), and their impact on assets and investment decision- making, have drawn lots of attention. In this paper, we propose a new knowledge inference design framework that provides concrete prescriptions for developing systems capable of supporting knowledge-based investment decision-making. Our framework design incorporates the advantages of both knowledge graphs and symbolic reasoning engines through the concept of a dual system. On the other hand, it overcomes the weaknesses of traditional expert systems, saving time in the knowledge input process, reducing the introduction of errors, and achieving more comprehensive knowledge coverage to obtain better predictive performance. Moreover, our proposed design artifacts are of significant importance in addressing the issues of causality and interpretability in the literature.
