Abstract

The invention provides an event prediction method and device based on data mining. The event prediction method includes the steps that search data relevant to predicted events is extracted aiming at all objects; outliers of feature values represented by the search data within a first set time period are recognized aiming at all the objects; the objects with the outliers meeting the preset prediction condition are fed into an alternative set; the prediction result that the predicted events happen to the objects in the alternative set within a second set time period in future is determined. Sudden events can be accurately predicted.

Description

【Technical field】 [0001] The invention relates to the field of computer application technology, in particular to a data mining-based event prediction method and device. 【Background technique】 [0002] In the process of social development, there are often many emergencies, which often have a huge impact on related fields and are closely related to people's lives. However, because of the suddenness, randomness and uncertainty of emergencies, it is very difficult to predict, but people put forward higher requirements for the prediction accuracy of emergencies. For example, in the field of stocks, equity incentives are a kind of emergency. After listed companies implement equity incentives, their stock prices will have stable excess returns. Therefore, for shareholders, the prediction of equity incentives is of great significance. However, a more accurate way of predicting events does not currently exist. 【Content of invention】 [0003] In view of this, the present inventio...
