Abstract  

This paper introduces a new method to extract the administrative-domain Ontology term automatically. Firstly, some words that are representative of the candidate terms should be extracted through the technology of word segmentation and the characters merger method. Secondly, the candidate terms are filtered by the way of C-value method and TF-IDF algorithm to achieve the automatic domain-specific term extraction in administrative-domain Ontology. Finally，the experiment shows that this method can improve the accuracy of the extracted terms and do not affect the recall-rate.
Key words： Administrative-domain Ontology        Terms        Characters merger method        C-value        TFIDF algorithm
