Generating Narrative Action Schemas for Suspens
نویسندگان
چکیده
A bottleneck in interactive storytelling is the authorial burden of writing narrative units, and connecting them to the interactive narrative structure. To address this problem, we present a hybrid approach that combines AI planning and evolutionary optimization in order to generated new plan operators representing possible story actions, within the framework of a planningbased interactive narrative system. We focus our work on inventing plan operators that are useful for contributing to suspenseful interactive stories, using suspense metrics that have been proposed in the literature. We devise an encoding scheme for converting a plan operator into a genetic-algorithm chromosome and vice versa, respecting constraints that are needed for an operator to be well-formed. We discuss the performance of the system, and several examples from preliminary experiments carried out to evaluate the evolved operators.

Generating Plots for a Given Query Using a Case-Base of Narrative Schemas
Computational generation of literary artifacts very often resorts to template-like schemas that can be instantiated into complex structures. With this view in mind, the present paper presents a casebased reasoning solution that builds a plot line to match a given query, expressed in terms of a sequence of abstraction of plot-bearing elements of a story, by retrieving and adapting templates for ...
متن کاملNASTEA: Investigating Narrative Schemas through Annotated Entities
In this paper, we investigate the distribution of narrative schemas (Chambers and Jurafsky, 2009) throughout different document categories and how the structure of narrative schemas is conditioned by document category, the converse of the relationship explored in Simonson and Davis (2015). We evaluate cross-category narrative differences by assessing the predictability of verbs in each category...
متن کاملInteractions between Narrative Schemas and Document Categories
The unsupervised extraction of narrative schemas—sets of events with associated argument chains—has been explored and evaluated from many angles (Chambers and Jurafsky, 2009; Jans et al. 2012; Balasubramanian et al., 2013; Pichotta and Mooney 2014). While the extraction process and evaluation of the products has been well-researched and debated, little insight has been garnered on properties of...
متن کاملEvent Extraction and Temporal Ordering towards Narrative Model Generation
Narrative generation is the process of automatically generating narrative stories (fictional or not) through a narrative model. With the advances in machine learning and natural language processing techniques, narrative generators have been able to create more creative and interesting text in terms of narrative contents and story telling techniques. These systems have applications in a range of...
متن کاملToward a Narrative Comprehension Model of Cinematic Generation for 3D Virtual Environments
Most systems for generating cinematic shot sequences for virtual environments focus on the low-level problems of camera placement. While this approach will create a sequence of camera shots which film individual events in a virtual environment, it does not account for the high-level effects shot sequences have on viewer inferences. There are systems which are based on well known cinematography ...
