This paper shows how to construct genre patterns, whose purpose is to guide
interactive story composition in a way that enforces thematic consistency. To
start the discussion we argue, based on previous seminal works, for the
existence of five fundamental genres, namely comedy, romance - in the sense of
epic plots, flourishing since the twelfth century -, tragedy, satire, and
mystery. To construct the patterns, a simple two-phase process is employed:
first retrieving examples that match our genre characterizations, and then
applying a form of most specific generalization to the groups of examples in
order to find their commonalities. In both phases, AI agents are instrumental,
with our PatternTeller prototype being called to operate the story composition
process, offering the opportunity to generate stories from a given premise of
the user, to be developed under the guidance of the chosen pattern and trying
to accommodate the user's suggestions along the composition stages.

构建体裁模式以指导交互式故事创作，确保主题一致性。采用简单的两阶段过程构建模式，先检索与体裁特征相匹配的示例，然后应用最具体概括的形式找到它们的共同点。两个阶段中的 AI 代理在故事创作过程中发挥重要作用，PatternTeller 原型用于操作故事创作，根据用户的给定前提生成故事，并在创作阶段中尝试适应用户的建议。
