Salience for Narrative Plan Similarity and Clustering
We developed a psychology-based metric for measuring story similarity in a narrative planner, which allows us to cluster solutions into meaningful groups. This is especially helpful for domain authors, who otherwise have a difficult time understanding the story worlds they are building, due to the narrative planner representing such a vast space of possible stories.

Sabre Spaces on GitHub


Sabre is a narrative planning platform that generates stories which meet the author's goals and only contain actions that make sense for the characters who take them. This fork adds options for generating multiple solutions and evaluating solution spaces by measuring story distance.

Demo

Domain Authoring Study Demo


This is a data collection tool I made that allows users to configure a story world (simulating domain authoring) and then explore it by randomly sampling different clusters of stories arranged in a helpful graph.

There are three versions. The Control version uses no clustering (all stories are randomly sampled from the full set modeled by the domain), while the Circles and Tree versions each use a different type of cluster graph and only sample the specific cluster the user clicked on.

The study assessed participants' understanding of the domain they had configured by asking them a series of questions like this: Here is a specific story, is this story modeled in the world you configured, or not? The demo doesn't collect data, but I left in the questions, so you can try it yourself and see your accuracy at the end. It's a good example of how authoring narrative planning domains can be surprisingly difficult! (For elaborate detail, see my dissertation...)
