This paper combined characteristics of agricultural topic tracking, researches attributes reduction of Rough Set Theory. The experimental results show that the algorithm is verified to be more feasible and effective. Solve the key problems of agricultural topic tracking.
Text classification is the key technology for topic tracking, and bayesian algorithm is a simple and efficient text classification model. So we use bayesian text classification model as key technology for topic tracking and vector space model as topic pre-process model to develop a topic tracking system. The experimental results show that the system has… (More)
