Methods of Generating the Context Graph and Its Summarization for Understanding the Elaboration Circumstances of Research Documents

In the elaboration work of research documents, which is an essential component of proceeding with research activities, it is important to sufficiently understand the elaboration contexts (e.g., the deliverables and the work history) so that they can be used in later work. However, the number of documents involved can become enormous, and work histories are inevitably complicated when research activities continue for a long period of time. Therefore, it becomes increasingly difficult to grasp the elaboration contexts. In our research, we aim to support the understanding of work circumstances by generating an elaboration context graph that organizes the contexts of elaboration work of research documents. In this paper, we mainly describe a method for graph summarization to enable easy understanding of the elaboration context graph, which can become quite large with long-term research activities. We also describe a case study in which we generated and summarized an elaboration context graph using actual history data, and discuss the effectiveness of the proposed methods on the basis of the results.
