Automatically constructing knowledge bases from online resources has become a crucial task in many research areas. Most existing knowledge bases are built from English re-sources, while few efforts have been made for other languages. Building knowledge bases for Chinese is of great importance on its own right. However, simply adapting existing tool-s from English to Chinese yields inferior re-sults.In this paper, we propose to create Chi-nese knowledge bases from online resources with less human involvement.This project will be formulated in a self-supervised framework which requires little manual work to extrac-t knowledge facts from online encyclopedia resources in a probabilistic view.In addition, this framework will be able to update the con-structed knowledge base with knowledge facts extracted from up-to-date newswire.Currently, we have obtained encouraging results in our pilot experiments that extracting knowledge facts from infoboxes can achieve a high accu-racy of around 95%, which will be then used as training data for the extraction of plain web-pages. 1
