AI-related business “DeNA x AI”

DeNA is developing many AI businesses. Here are four.

Improving operational efficiency of liquefied natural gas terminals

DeNA is jointly developing with Kansai Electric Power an AI solution that optimizes the fuel operation of liquefied natural gas .

It is very difficult to formulate an efficient fuel operation plan, and quality standards cannot be met unless the plan is well organized. In that case, additional resources may be required, and many years of experience and knowledge are required to achieve both safety and stability and cost reduction.

Until now, two experienced engineers worked on schedule design, but after understanding the details of the work, we succeeded in realizing automatic creation of fuel operation plans using AI that achieves both safety and stability and cost reduction. did.

Create “fontgraphy” to generate logos from voice

“fontgraphy” is a service that generates a personalized logo from each person’s voice. It was released to express the theme of DeNA’s 20th anniversary that anyone can be the leading role.

After that, we received a request from Dai Nippon Printing Co., Ltd. (hereafter, DNP) and provided customized fonts for DNP as “fontgraphy for DNP.”

With fontgraphy, just by speaking to your smartphone, AI analyzes your voice quality, and based on the results of that analysis, selects the font and image for the letters “DNP”. By multiplying the two, an original logo tailored to each speaker is generated.

In developing fontgraphy, we collected voice data from approximately 800 DeNA employees and modeled them by classifying eight impression tags, such as “sweet, cool, and lively,” into four-level scores.

Providing “speech synthesis technology” for virtual security systems

The “virtual security system” is equipped with the world’s first AI, realized by combining the security know-how that SECOM has cultivated so far as Japan’s first security company with the latest technologies of AGC, DeNA, and NTT DOCOMO. This is a security system in which virtual characters “virtual guards” provide stationed security services.

The system will be in charge of security surveillance and reception, among the duties previously performed by stationed security guards. This reduces security costs at manned facilities, enables efficient staffing, and reduces operating costs.

DeNA provided the original character design for the “virtual security guard” and voice synthesis technology for responding to visitors. Speech synthesis technology, which synthesizes speech from text, is used in car navigation systems, broadcasting in train stations, etc.

The virtual security guard uses a recurrent neural network that considers series data in the speech synthesis model, making it a natural voice that looks like an actual human being. It’s also highly scalable, allowing you to voice any text.

Development of game play support AI tool for “Gyakuten Othellonia”

“Gyakuten Othellonia” is a fighting game app that allows you to easily play with the rules of Othello provided by DeNA.
DeNA has developed a battle AI as a practice opponent who can use various decks in Gyakuten Othellonia, a recommendation AI that automatically builds recommended decks, and an AI that supports game balance adjustment.

In the mode where you can play against the computer, we have introduced a battle AI that feels like a real human, and you can easily learn how to fight against the AI ​​and how to fight.

With automatic deck generation, we aim to create a deck that suits the player from among thousands of characters, and through AI support, we aim to have people notice the “interestingness” and “depth” of the game.

In a strategic game, the game becomes more complicated over the years of operation. Therefore, AI automatically repeats the game play, evaluates the character’s performance, and supports the planner’s decision making, realizing more efficient balance adjustment work.

DeNA, an ever-changing company

So far, we have introduced the AI ​​business that DeNA is working on.

However, DeNA is developing a wide variety of businesses other than the AI ​​business. This time, we will introduce five businesses.

Live streaming business “Pococha”

DeNA operates the live distribution app “Pococha”. Pococha is a live distribution app that allows you to easily enjoy two-way communication between various unique rivers and listeners who are viewers, and has achieved 3.45 million downloads in December 2021.

Pococha’s goal is to create a place where real people can communicate with each other on the Internet. With the goal of “everyone in the world can become a special presence for someone else”, we provide a place where people can be themselves, even on the Internet, by calling each other’s names and talking to each other. doing.

In service design, we focused on lowering various hurdles so that even ordinary people can easily start streaming. Eliminates time-consuming work such as video editing, you can easily distribute by simply pressing the distribution button.

In addition, we have released a live distribution application for global use, and in January 2022, we will release a live distribution application “Voice Pococha” that connects with voice.The live streaming business is one of the businesses that DeNA is focusing on. It’s one.

Sports business “Yokohama DeNA BayStars”

DeNA has sports businesses in baseball, basketball and soccer. In recent years, data analysis using technology in the field of sports has made great progress, and the baseball team “Yokohama DeNA BayStars” is also implementing measures to strengthen players using technology.

In addition, in November 2021, we released “PLAYBACK 9”, a service that utilizes NFT. PLAYBACK 9 is a service that allows you to purchase and view digital items that have been certified by NFT. We sell the famous scenes of the game as official digital items of the team, and you can experience the world of conventional trading cards digitally. In the future, we plan to add a MARKET function that allows users to buy and sell scenes that they have obtained.

Health care business “kencom”

“Kencom” is an app provided by DeSC Healthcare, a joint venture between DeNA and Sumitomo Corporation. kencom incorporates a mechanism that allows users to easily check the results of their health checkups and promotes health promotion in a fun way, and is being introduced by health insurance associations and local governments.

With kencom, you can view health data such as checkup results on your PC or smartphone. In addition, we update health information according to user’s health data and preferences on a daily basis. can be inserted.

By February 2022, it will be used by a total of 99 organizations and about 4.8 million people, and will be linked with the cognitive function service of Nippon Tect Systems.

Automotive business “GO”

DeNA is also focusing on the automotive business.

Ride-hailing apps such as Uber are growing rapidly around the world, but the percentage of people using ride-hailing apps in Japan was only about 2% of the total. Therefore, with the aim of expanding the scale of the dispatch app, DeNA launched a taxi delivery app called “Japan Taxi” in February 2020 that combines the dispatch app business “Japan Taxi” and “MOV” provided by DeNA. GO” distribution started. Currently, 20 prefectures (*excluding some areas) are supported.

In addition, we are distributing the “GO BUSINESS” service, which can be linked with the expense settlement system, and can cut the time and effort required to settle taxi receipts. The service will be released in October 2021, and by March 2022, the number of registered companies will exceed 2,500.

Game business “Touhou Danmakukagura”

DeNA has released various smartphone applications. Released in August 2021, the Touhou Project’s first official official game “Touhou Dan Makukagura” has exceeded 4 million downloads in a month since its release.

Also, Google Play Best of 2021, which awards Google Play content that gained popularity in Japan in 2021, won the cute and casual categories.
