Keyword Extraction using Term-Domain Interdependence for Dictation of Radio News

Abstract

In this paper, we propose keyword extraction method for dictation of radio news which con-sists of several domains. In our method, news-paper articles which are automatically classified into suitable domains are used in order to calcu-late feature vectors. The feature vectors shows term-domain interdependence and are used for selecting a suitable domain of each part of ra-dio news. Keywords are extracted by using the selected domain. The results of keyword extrac-tion experiments showed that our methods are robust and effective for dictation of radio news.
