Hello, we are happy in alt.chi and introduce BunCho, AI supported story co-creation tool
via unsupervised multitask learning to increase writer creativity in Japanese.
We are from University of Tsukuba, Japan and R&D Center for Digital Nature.
The first author is Hiroyuki Osone, a very talented master student
who built AI and user interfaces. If you have time, must play with BunCho.
I am the second author Jun-Li Lu.
Our advisor is Yoichi Ochiai, who is also Director of R&D Center for Digital Nature.
Recently in online novel community, the novels lose diversity and originality, is reducing.
Because they (novel creation) are driven by the crowd preference due to the ranking or business.
In AI co-creation, we can see the recent works on Songwriting, or for music, which focused on novices.
In the interface issues, the past issues focused on how to optimize AI to find out the optimal inputs,
but recently that we are provided more diverse and flexible inputs to AI.
The AI can receive more kinds of inputs and produce more outputs.
GPT-2 or GPT-3 have the capability of understanding languages.
How BunCho assisted story creation.
Let's see what's the writing issues.
Novice writers face that they have few ideas about writing or lack some skill (e.g., how to express).
Experienced writers face how to write in details, although they may have some storyline.
BunCho used GPT-2.
Comparing (BunCho) with other tools,
Both (including related work) had many novels, but we used a large-scale, 40 GB text data (in Japanese).
We used many (trained) novels.
We have more detailed generations like we have title/synopsis, and we can input the templates.
Our idea is to provide multiple inputs.
So the user can put many kinds of ideas to generate the contents they want, by using template or genre.
For example, Science Fiction and the related genre, sub-genre, or by SNS.
You can input keywords and genre to generate the synopsis, pick some (generated synopses) of them.
Here we propose AI TRPG, which is interactive writing as game setting.
You can set the background (of story) as synopsis.
You can adjust the contents to be descriptive or dialogue (just like conversation).
(The process is) AI suggested, you revising, and then AI suggested and it's a loop.
The (co-created) results can be diverse, creative, and unexpected.
The left one is AI generated result, which can be diverse and much contentful.
(In user study) more than 60 percent of writers enjoyed writing with BunCho and they thought their stories could be extended.
The creative contents could be suggested for novice writers, compared with correctness (one of measures).
When you got struggled, we could provide ideas.
Positive is creative stories could be suggested and useful for novices.
However, the negative is, the inconsistent AI results with what you expected, and it took time to revise AI suggestions.
BunCho brings more factors when considering in interface design,
different level users, technology like AI, or online community.
like domain knowledge (e.g., story creation),
We especially contributed to creativity, diversity, or originality for personal (in story creation),
compared to those made towards public or ranking.
