CSWBench: Evaluating Context-Sensitive Code-Switching in Creative Writing

CSWBench is a benchmark designed to evaluate context-sensitive code-switching in creative writing, featuring two settings: Focused Narrative and Extended Narrative. The accompanying CSWEval framework assesses event-level aspects such as Licensing, Contextual Appropriateness, and Functional Gain, as well as whole-text quality metrics tailored to each narrative setting. Experiments with twelve large language models reveal that while models show some code-switching competence, performance varies significantly across narrative contexts, with stronger challenges in multilingual literary integration and clearer associations between narratively salient switches and contextual/functional realization.

PlotTwist: A Creative Plot Generation Framework with Small Language Models

arXiv:2603. 16410v2 Announce Type: replace-cross Abstract: Creative plot generation presents a fundamental challenge for language models: transforming a concise premise into a coherent narrative that sustains global coherence, character development, pacing, tone consistency, and emotional progression.

How LLMs Build Fictional Worlds: Setting and Narrative Space in AI-Generated Creative Storytelling

The paper investigates how Large Language Models (LLMs) construct fictional worlds, specifically examining setting as a measurable aspect of storyworld creation. By generating 1,000 AI stories per model in English and German and comparing them to human-authored fiction from Project Gutenberg, the authors classify narrative space into five categories—action, perceived, visual, descriptive, and no space—using fine‑tuned BERT classifiers. Results show that human texts mainly use action space, grounding narratives in character-environment interaction, while LLMs consistently overproduce perceived space, focusing on atmosphere and affect, with this pattern varying by model and language.

Characterizing Narrative Content in Web-scale LLM Pretraining Data

The paper presents a detailed examination of narrative elements—agency, setting, and events—within the Dolma web-scale pretraining corpus. Using a framework of 11 interpretable dimensions, the authors hand‑annotated 400 passages, expanded this to a 25,000‑passage LLM‑labeled dataset, and trained NarraBERT models to predict narrative features across 13 million passages, producing the NarraDolma dataset. The study reveals that narrative structure is measurable at scale and that narrative qualities vary unevenly across different data sources, topics, and formats, highlighting gaps in current data curation practices.
