First of all, I would like to thank the IDF Japanese Processing Analysis Performance Evaluation Committee, the IDF Secretariat, and other related parties for providing such an opportunity.I feel that it is very significant that this evaluation report objectively proved the high performance of Lit i View.

The nine types of character codes to be evaluated cover most of the characters currently used in Japan.The ability to correctly process and search all of these character codes is the basis of the high Japanese processing power of Lit i View. On the contrary, if this processing and search accuracy is insufficient, how excellent the analysis function is. Even if it does, it cannot perform its full function as a system.

In the evaluation results of each item, the precision rate was 100% for all items, proving that it was possible to perform highly accurate searches without false hits.Regarding the recall rate, not all items have achieved 100%, but this includes items that do not have functions in this system, such as search in video files and Japanese fluctuation search. This is the cause, and for those with other functions, the search is executed correctly.In addition, regarding the evaluation of e-mails, all processing and searches including applications unique to Japan such as Becky were performed correctly, and it can be said that the high Japanese processing analysis of Lit i View was demonstrated comprehensively.

In the future, we have high expectations that the results of this evaluation will be utilized in various situations, and that the number of evaluation items and targets will increase, and that evaluations will be made from a more diverse perspective.
