Abstract: A pyramid method for automatic summarization evaluation based on Dependent Content Units(DCU) is proposed. By identifying DCU, the pyramid model is set up, and the corresponding process of automatic evaluation is given. The method avoids the unstability in manual processing and implements the full automation in the whole process of evaluation. Simulation experimental results show the relevant coefficients called Person and Sperman of this method are higher than traditional ROUGE-1 algorithm.
