Abstract(in English) | A method is proposed for the post-processing of Japanese morphological analysis using transformation rules and contextual information. The method corrects both segmentation errors and part-of-speech tagging errors. The transformation rules are acquired automatically by error-driven supervised learning. The rules consist of various types, such as lexicalized rules and schematic rules. Each rule is assigned a value for reliability. The rules are not specifically tailored for detecting unregistered words, but can correct errors caused by unregistered words. In addition, we propose the use of contextual information obtained from the result of analysis of neighboring sentences. The information reinforces unregistered word detection and disambiguation. The post-processing improved the precision of the analysis of an open corpus by 3%. |
