Research on Case Based Reasoning System of Stock Theme Events Based on Ontology
摘要
Abstract
In stock markets there are some events that their occurrences will significantly affect stocks’ prices and profits. In order to help investors accumulate experimental wealth and quickly make decisions,in this paper a case-based reasoning system for subject events in stock markets was constructed with the combination of ontology theory and case-based reasoning method,then with information about subject events and data about market fluctuations,the ontology structures were defined for event cases and type ontologies were set for fi-nancial events. In this system,OWL-DL was used to describe ontology,and Protégé4. 2 was applied to build the ontology base. By stud-ying the feature properties and using similar measuring method to retrieve similar cases,a target event was finally analyzed in detail. In the end a trending analysis for a certain event to the stock markets was given,the results showed that using similar cases to predict short-term market effect was feasible,and meantime the recall ratio was obviously improved after introducing ontology into the reasoning system, which means that the proposed method is reasonable and effective.关键词
