[2Xin5-14] Development of a tool to support a process of reasoning by using relation extraction

〇Misa Sato1, Hiroko Otaki1, Yasuhiro Sogawa1, Kohsuke Yanai1 (1.Hitachi, Ltd.)


There are business situations in which reasoning are made by connecting multiple knowledge from large text documents, such as research papers and business documents. In such cases, especially for those who are not familiar with the business domain, it is necessary to repeat the process of searching for relevant documents, reading, re-searching, and reading again and again because they do not have enough knowledge. This tool supports this inefficient repeated process. The tool is equipped with a knowledge DB that has relation knowledge extracted from a large amount of text in advance, using natural language processing technology. Users can define a reasoning hypothesis to be examined on the tool, and then retrieve the relevant knowledge from the DB one after another to easily make inferences using the large amount of knowledge. In this paper, we describe the details of the method and its effectiveness.
