Abstract

Existing studies have utilized Wikipedia for various knowledge acquisition tasks. However, no attempts have been made to explore multi-level topic knowledge con-tained in Wikipedia articles' Contents ta-bles. The articles with similar subjects are grouped together into Wikipedia cat-egories. In this work, we propose novel methods to automatically construct com-prehensive topic hierarchies for given cat-egories based on the structured Contents tables as well as corresponding unstruc-tured text descriptions. Such a hierarchy is important for information browsing, doc-ument organization and topic prediction. Experimental results show our proposed approach, incorporating both the structural and textual information, achieves high quality category topic hierarchies.
