An ontology-based framework is proposed in this research to improve
financial data quality. The framework can be used to address
various types of problems associated with online financial data. The
positive impact of the framework on the performance of financial
decision-making is empirically demonstrated with asset valuation.
Improving quality of financial data is just the first step toward effective
financial decision-making. In view that the financial market is dynamic,
the domain knowledge modeled in FinO (Financial Ontology)
should evolve accordingly
