Contemporary research demonstrates that such explicit decompositions are critical for generating stories that are coherent at scale, maintain entity and plot consistency, and achieve sufficient thematic and stylistic diversity. ## 1. Modular and Hierarchical Architectures Recent story generation systems consistently employ hierarchical or modular pipelines. Canonical pipelines include two-stage architectures (outline→story), coarse-to-fine decompositions (semantic abstraction→surface realization), and multi-agent or collaborative frameworks. Modular separation allows for explicit global planning followed by local realization, or interactive feedback loops between planning and revision. For example, "Plan-And-Write" implements a clear two-stage pipeline—a Planner produces a sequence of storyline keywords or events, and a Writer conditions on this plan to realize coherent text [1811.05701]. Similar decompositions appear in content-planning pipelines that factorize $p(y \mid x)$ as $p(z \mid x)\cdot p(y \mid z, x)$, where $z$ is a structured plot or outline [2009.09870], [2010.08822]. Pipeline variants: | Architecture | Planning Layer | Realization Layer | |--------------------------|-------------------------------------|-----------------------------------| | Plan-and-write | Keyword or event sequence | Seq2Seq conditional LM w/ attention| | Consistency-enhanced | Abstract "outline" (sentence/keyword) | Transformer-Decoder w/ outline context| | Multi-agent frameworks | Distributed agent event planning | Multi-agent writing/feedback | | Predicate-argument | SRL frames + placeholders (SRL/NER/Coref) | Surface realizer & entity refiller | This modularization contrasts with pure left-to-right LM generation, affording structural control and tractable intermediate objectives [2506.16445], [1902.01109]. ## 2. Planning Representations and Strategies Planning modules employ diverse representations: sequences of keywords, predicate–argument structures, events annotated with time/role/object, subject–verb–object (SVO) triples, or even logic-based and ASP-encoded narrative functions. - In static planning, the full story structure (e.g., a keyword sequence or graph) is generated before any text realization [1811.05701], [2406.00554]. - In dynamic/interleaved planning, planning and realization alternate at each step, allowing finer coupling and immediate feedback for each action [1811.05701]. - Predicate-argument or SRL-based plans encode story events as a sequence of verb frames or SRL tuples [1902.01109], allowing explicit control over event diversity and arguments. - SVO triplets structurally enforce event atomicity and provide cross-event entity linking, facilitating consistent plot node expansion [2506.02347]. Formally, plans are generated autoregressively: \[ p(z|x)=\prod_{i} p(z_i|z_{
