基于数据仓库及决策树算法的电网事故事件信息智能检索方法研究

Intelligent Retrieval Method of Power Grid Accident Information Based on Data Warehouse and Decision Tree Algorithms

针对电网事故事件,以大量电网事故事件相关信息为基础数据形成数据仓库。针对事故事件数据自身的特点,研究实现有效的索引结构。针对不同数据类型,设计基于分类与回归树算法运用。从而提高对数据检索速度,提高电网事故事件的检索效率。

In view of power grid accidents, this paper builds a data warehouse based on a large number of information related to power grid accidents. According to the characteristics of accident data itself, it studies and implements an effective index structure. For different data types, it designs classification and regression tree algorithm. Thus, the speed of data retrieval is improved and the efficiency of Power Grid Accident retrieval is improved.
