Abstract  

Seeing that the keyword or key phrase can represent the feature of text, keyword extraction and filtration has great significance for information retrieval, information extraction and knowledge discovery. This paper first investigates current keyword extraction methods. Then it uses existing thesaurus and tools in the medical field and BM25F model in proposing a method for keyword extraction and filtration from medical texts. The proposed method mainly solves two key problems:identification and extraction of keywords, evaluation of keyword value and filtration of keywords. This paper applies the method on documents in the field of osteoarthritis from the year 2001 to 2007, and verifies its effectiveness, which offers an effective way for extracting keywords in knowledge discovery.

Key wordsKeyword extraction      Keyword filtration      BM25F      MMTx      Text mining      Medical data mining
