| Outline of Final Research Achievements |
I have constructed language resources and tools for negation focus analysis in Japanese text. They include the following three main components: (1) a corpus of 2,147 pairs of negation triggers and their foci, (2) a new data format to support annotation layers for data sharing, and, (3) a detector of the focus of a negation trigger in Japanese, which achieved accuracy of 80 % in the domain of hotel reviews and news text.
