FRONTEO Inc. (Headquarters: Minato-ku, Tokyo, President: Masahiro Morimoto, hereafter FRONTEO) is now using the AI-based document review tool "KIBIT Automator" in international fraud investigation projects. We are announcing that we have efficiently detected misjudgment by reviewers and achieved a significant improvement in error rate.


Discovery in US civil courts requires you to accurately find evidence in a huge amount of documents within a limited amount of time. FRONTEO's AI-based document review tool "KIBIT Automator" is already in operation in the United States and Japan, reducing the amount of documents that require a lawyer's review by up to 90% and the amount of review documents per hour. We have achieved results such as a significant speedup of more than 650 cases (30-40 cases / hour visually by humans).


In document reviews using KIBIT Automator, lawyers "relevant / relevant" randomly selected documents from a huge number of documents to be investigated (which may reach millions depending on the case). It is classified as "no sex".AI learns the classified data as teacher data, and AI gives a score to the document to be investigated based on the judgment of the lawyer (1 to 10,000 points, the higher the score, the more relevant the judgment) ).Reviewers have improved work efficiency and speed by proceeding with reviews in descending order of score.


In this fraud investigation project, we are utilizing the heat map function with enhanced review quality improvement function.At the end of the primary review, the documents marked "relevant" will be used as teacher data, and all documents tagged "unrelated" in the primary review will be analyzed again by AI and the score will be reassigned. ..Among them, documents in which the judgment of AI and the judgment of the reviewer are greatly different (example: AI judges that it is "highly relevant", but the reviewer seems to judge that it is "not relevant". By marking (the document displayed in dark red in the figure and highlighted by the frame) and reconfirming the document with priority, it is possible to prevent omissions and omissions due to human judgment mistakes. (Approximately 8 times the accuracy of the error detection rate by random sampling).


<Conventional method>
・ Randomly sample some documents that are judged to be “irrelevant” in the primary review and review them again.


<Priority confirmation based on heat map + AI and human judgment divergence>
・ AI analyzes documents that are judged to be "irrelevant". Reconfirm from the one with the highest degree of divergence between AI and human judgment


By reconfirming documents with a high degree of divergence, we succeeded in extracting "relevant" documents that were mistakenly classified as "unrelevant" with about eight times the accuracy of conventional methods.


As a pioneer of digital forensics / discovery in Japan, FRONTEO will continue to strive to improve and develop solutions that help streamline fraud investigations and litigation support.
