また、「なりきりAI京町セイカ」のAIの学習に必要なデータ収集は、精華町民協力のもと実施され、企業・行政・住民の三者の協力による地域連携の取り組みとして進めていくもようだ。
「なりきりAI」の育て方同実験で活用されている「なりきりAI」は、有名人や特定のキャラクターを模した対話システムであり、NTTメディアインテリジェンス研究所にて開発されている。これまで、ドワンゴとの連携により「なりきりAI アマデウス紅莉栖」を、ドコモとの連携により「なりきりAI 田中ヒメ」などを構築し、NTT R&Dフォーラムやニコニコ超会議などに出展してきた。
「なりきりAI」の特徴は、そのキャラクターの個性を持って対話をするということだ。その「らしさ」を学習するにあたり、AI育成プロジェクトを立ち上げ、そのキャラクターの知識を持つ一般の人を募集。
「アマデウス紅莉栖」の場合、当選者は牧瀬紅莉栖と会話をするように聞きたいことを質問する。そして自分がした質問やほかの当選者の質問に「牧瀬紅莉栖が答えそうなこと」をなりきって回答。その後、ほかの回答者のこたえを見て「牧瀬紅莉栖っぽい」と思う回答に「ポイね！ 」を押すという流れだ。
こうして、キャラクターの個性をもったAIが育っていくという。しかし、現状の「なりきりAI」はエンターテイメント目的で雑談対話を行う技術のため、受付や案内などを行うタスク対話はできなかった。
そこでこのたび、対話データの収集方法および対話制御モデルを工夫し、タスク対話と非タスク対話（雑談）を両立させるシステムを構築。これを「なりきりAI」に適用することで、親しみやすいキャラクターが雑談とタスク対話の両方を行えるという。
インタラクションを持つAI今回「なりきりAI」となるのは、精華町の広報キャラクター「京町セイカ」。対話データを、精華町の知識を持つ町民と精華町に行ってみたい・興味があるという人から収集し、「なりきりAI京町セイカ」の知識として集約した。このデータ収集方法は、従来の方法に比べ「正確性の高い情報」と「需要の高い情報」を低コストで得られるというメリットがあるとのこと。
また、これまで難しかった役場業務に関する対話を実現できる対話制御モデルを作成するという。役場業務には、町に関する非常に広範な情報の提供や案内が求められたり、ほかの窓口への引き継ぐなど深く情報をやり取りしたりする必要が出てくる。そこで広範かつ高度な知識を得るべくデータ収集方法を改善し、窓口業務に関する対話を実現できる対話制御モデルを学習する。
このたびの「なりきりAI京町セイカ」は、雑談はもちろん、観光案内や窓口受付ができるうえに、タスク対話の途中でも来訪者からの雑談や質問に柔軟に答えることができるインタラクションを備えているようだ。同実験では、「なりきりAI京町セイカ」が窓口業務の一部を補助できるかどうかを精華町役場にて検証する。
同実験の成果は今後のイベントなどで発表するとのこと。

NTT and Seika Town start demonstration experiment of AI dialogue system using "Narikari AI"!

Nippon Telegraph and Telephone Corporation (NTT) and Seika Town Office in Kyoto Prefecture have converted the Seika Town public relations character "Kyomachi Seika" into an AI as "Narikari AI Kyomachi Seika" and provided information, tourist information, and reception desks in addition to chats. Build a dialogue system that can do the job.
In addition, the data collection necessary for learning AI of "Narikiri AI Kyomachi Seika" will be carried out with the cooperation of the Seika townspeople, and it will be promoted as an initiative of regional cooperation through the cooperation of the three parties of companies, administration and residents. ..
How to raise "Narikari AI" "Narikari AI" used in the same experiment is a dialogue system that imitates a celebrity or a specific character, and is developed at NTT Media Intelligence Laboratories. So far, we have constructed "Narikari AI Amadeus Kurisu" in collaboration with Dwango, "Narikari AI Tanaka Hime" in collaboration with Docomo, and exhibited at NTT R&D Forum and Nico Nico Chokaigi.
The feature of "Naririkiri AI" is that it has a character's individuality in the dialogue. In order to learn its “likeness”, we launched an AI training project and recruited ordinary people with knowledge of the character.
In the case of "Amadeus Kurisu," the winner asks what they want to ask to talk to Kurisu Makise. Then, he answered the questions he asked himself and the questions of the other winners by saying "What Kurisu Makise is likely to answer". After that, looking at the answers of the other respondents and pushing "Poy!" to the answer that you think "Makise Kurisu-ish" seems.
In this way, AI with the character's individuality is said to grow. However, the current "Narikari AI" is a technology for chatting for entertainment purposes, so task dialogues such as reception and guidance were not possible.
Therefore, we have devised a method of collecting dialogue data and a dialogue control model to build a system that makes task dialogue and non-task dialogue (chat) compatible. By applying this to Narikiri AI, it is said that friendly characters can perform both chat and task dialogue.
AI with interaction This time, “Narikari AI” will be “Keimachi Seika,” a publicity character from Seika Town. Dialogue data was collected from townspeople who have knowledge of Seika Town and people who want to go to Seika Town and are interested in it, and gathered it as knowledge of "Narikiri AI Kyomachi Seika". This data collection method has the merit of being able to obtain "information with high accuracy" and "information with high demand" at low cost compared to the conventional method.
In addition, it is said that it will create a dialogue control model that can realize dialogues related to office work that was difficult until now. For office work, it is necessary to provide and provide a very wide range of information about the town, and to exchange information in depth, such as handing it over to another window. Therefore, we improve the data collection method in order to obtain a wide range of advanced knowledge, and learn a dialogue control model that can realize dialogues related to counter operations.
This time, "Narikiri AI Kyomachi Seika" not only allows for chats, but also provides tourist information and reception desks, as well as an interaction that allows you to flexibly answer chats and questions from visitors even during task dialogues. It is. In the same experiment, it will be verified at the Seika Town Office whether "Naririkiri AI Kyomachi Seika" can assist some of the window operations.
The results of the experiment will be announced at future events.
