Abstract:
The strategies for automatic extraction of key words from medical news were put forward by adding the MeSH terms into the general classification table in combination with the length of MeSH terms and location-weigh-ted MeSH terms.The key words randomly selected from 100 papers reporting medical news on 10 Websites were in-dexed and verified by machine indexing.The extraction accuracy was 0.34 and the recall rate was 0.30, showing that the strategies can be used for automatic extraction of key words from medical news.
