Abstract

Currently news sites and news index sites basically provide streams of news with simple classifications or keyword based searching with publication data. When we try to search for news involving a number of potential keywords or unknown keywords, then the task becomes manually tedious or almost impossible. We present automatic methods for constructing news directory systems which contain collections of news index information with flat or hierarchical classification structures. This directory structure enables us to reach the news articles without knowing the keywords exactly. We implemented and evaluated one sample news directory system.
