Abstract
This paper introduced an intelligent match method of emergency plan based on keywords extraction. Words frequency, part of speech and position of framework are taken as the keyword weight factors. Least-squares error linear estimate method is used to regulate the factors and calculate keywords weight. And Vector Space Model is set up to calculate the maximum similarity between plan texts to complete design of plan match. The expansible practical parameters adjustment module is provided to adapt to diversity of match plan with emphasis part. Compare with tf*idf, the experimental results show that the presented method is more promising in intelligent match method of emergency plan.
