Identifying the subjective relationship is important for opinion mining on product reviews in Chinese. The commonly used identification methods adopt classifiers as the identifier. However, it is difficult to maintain high accuracy and high recall rate simultaneously for the instability of exciting classification method.

In the field of data mining, clustering is one of the important methods. K-Means is a typical distance-based clustering algorithm; 2-tier clustering should implement scalable clustering by means of dividing, sampling and knowledge integrating. Among those tools of distributed processing, Map-Reduce has been widely embraced by both academia and industry. Hadoop is an open-source parallel and distributed...
This paper analyzed the complexity of electric driving control system of electrical wheels autonomous dump truck, and proposed active disturbances rejection control (ADRC) strategy for the transmission system of the truck, designed the active-disturbances-rejection transmission control system. The simulation result shows that the ADRC controller satisfies the system requirements, and has a higher...
