Research on Operation-based Correlation in Personal Dataspace

Operation of user was defined. The weight of operation was expressed. The variable quantity of user behavior was computed by weight. 3-ary vector data definition was expanded. Data item was defined by 4-ary vector in personal dataspace. Correlation of data for user was defined by weight. Current weight of data was defined by initial weight and variable quantity of user operation. A library dataspace model was designed. The weights of data were verified by using a sample in the library dataspace for ten days. The result proved the correlation of data was very important and useful in personal dataspace.
