Published in Proceedings of the 4th Workshop on Argument Mining (ArgMining2017), 2017
We propose a method for the annotation of Japanese civil judgment documents, with the purpose of creating flexible summaries of these. The first step, described in the current paper, concerns content selection, i.e., the question of which material should be extracted initially for the summary. In particular, we utilize the hierarchical argu-ment structure of the judgment documents. Our main contributions are a) the design of an annotation scheme that stresses the connection between legal issues (called issue topics) and argument structure, b) an adaptation of rhetorical status to suit the Japanese legal system and c) the definition of a linked argument structure based on le-gal sub-arguments. In this paper, we report agreement between two annotators on sev-eral aspects of the overall task.

We propose an annotation scheme for the summarization of Japanese judgment documents. This paper reports the details of the development of our annotation scheme for this task. We also conduct a human study where we compare the annotation of independent annotators. The end goal of our work is summarization, and our categories and the link system is a consequence of this. We propose three types of generic summaries which are focused on specific legal issues relevant to a given legal case.

Toward Automatic Extraction of Characteristic Features of English Composition by Japanese College Students : Preliminary Experiments and Issues to be Addressed
We are accumulating electronic files of English composition by university freshmen. For the past ten years or so, about 50 to 90 students enrolled in three English classes taught by the last author are submitting 15 essays per year, each in three different versions. The first is what the students come up with in half hour or so in class after engaging what we call "oral response practice," in which a group of three students in turn read a question card aloud, respond to the question and video record the interaction. Sets of 10 question cards around one topic are prepared by the teacher and distributed to the groups with a video camera. After class, students will spend some time to "complete" their compositions and submit them during the next class and review other students' essays within groups of six. The students are asked to revise the essays and submit the final version during the following class. In addition to the students' peer review comments, it would be desirable if the students can get feedback by statistical analysis of parsing and other processing of their own essays but the files submitted has to go through some pre-processing for the parser and analyzers to work properly. In this presentation, we report on your preliminary study and experimentation.
