The CIPS-SIGHAN CLP 2014 Chinese Word Segmentation Bake-off

This paper summarizes the SIGHAN 2014 Chinese Word Segmentation bakeoff in several aspects such as dataset, evaluation results. In addition, we analyze errors of segmentation by instance and make a suggestion for improving segmentation systems. 1 Goal of the Chinese word segmentation bake-off Chinese Word Segmentation is the preliminary step for Chinese information processing, which is extremely important and never neglected. Due to the properties of Chinese, the performance of Chinese word segmentation has an effect on the following analysis of Chinese text. As the organizer of the bake-off in Chinese word segmentation, not only do we show the performance of all participated systems, but also try to find out the weak point of these systems. In this way, participants are able to learn advantages of their systems and realize the problems which they did not pay attention to so that they could improve their system according to our feedbacks, which turns out to promote the study of Chinese word segmentation.
