SaveACTOR: Action-Centered Temporal Organization for Literary Role-Playing Agents
Organizations: Harbin Institute of Technology · National University of Singapore · Shanghai Jiao Tong University · University of Oxford
Abstract
Large language agents for literary role-playing are typically modeled around dialogue generation, leaving characters' non-dialogue behaviors and their dynamic evolution over story time underrepresented. In this paper, we propose ACTOR (Action-Centered Temporal Organization for Literary Role-Playing Agents), an automated framework for constructing such behavior trajectories from raw novel texts. ACTOR extracts dialogue and persona-relevant non-dialogue behaviors, represents each behavior using a Thought-Action-Observation structure, and organizes behavior trajectories according to the internal temporal order of the story. We build a behavior dataset from 143 diverse literary works. For each source behavior, we generate counterfactual behaviors that are contextually plausible yet inconsistent with the character's persona. We find that existing models struggle to reliably infer character-consistent actions from historical behaviors and evolving character states. Using these behavior pairs, we train models with Regularized Preference Optimization (RPO), which augments DPO with a negative log-likelihood loss on the source behavior to jointly optimize behavior preference and generation. We further design a four-way next-behavior selection task to evaluate the model's ability to faithfully mimic character actions. Across 17,560 evaluation instances, the model trained on ACTOR's preference pairs achieves substantially improved accuracy. This result demonstrates that structured, temporally organized supervision enables models to leverage character profiles and prior behaviors to infer subsequent actions, greatly advancing literary role-playing beyond mere dialogue imitation. Code and data are available at https://github.com/SilentStar233/ACTOR.

Figure 1: Overview of our behavior-modeling evaluation. Given character-related information, the model needs to select the most plausible next action from four options.
Figure 2: ACTOR dataset construction pipeline. Plot-conditioned context is transformed into Thought–Action–Observation (T-A-O) units, followed by key-behavior validation, temporal and entity alignment, and dynamic profile updates for sustained changes. Each behavior is paired with three situation-plausible but target-character-inconsistent alternatives, which are refined to match the real action’s form and texture while leaving the real action unchanged.

| Case | Relevant pre-action evidence | Qwen-2.5-7B-Instruct | ACTOR-Qwen-2.5-7B / Source behavior |
|---|---|---|---|
| State transformation | Formerly cold and dismissive of poverty, the character later resolves to change and repeatedly behaves with kindness and generosity. He only appears severe when the clerk arrives late. | Punishes the clerk and refuses further support for his family. | Raises the clerk’s salary, supports his family, and asks him to add coal to the fire. |
| Dialogue continuity | The profile lists only the character’s occupation. In the conversation, she alternates between teasing disclosures and assurances about another person’s visits. | Promises to disclose the information: “I’ll tell.” | Reassures the interlocutor that she will not disclose it: “Certainly not.” |
| Action adaptation | After declaring his willingness to kill an opponent and drawing his sword, the character is challenged by another character who intervenes. | Abandons the attack and shields the original target. | Redirects the attack toward the intervening character. |

| Prompt | Template and requirements |
|---|---|
| Plot Segmentation | (intro) Partition the supplied book chunk into consecutive, non-overlapping plot segments for downstream character-action extraction. (requirements) Return the exact first and last sentences of every segment. Preserve source-text order and continue truncated segments from the previous chunk. Maintain the canonical character registry and report newly observed aliases. Do not create overlapping segments or include a broad parent plot together with a contained sub-plot. Return strict JSON only. |
| Overlap Repair | (intro) Repartition a source-text region that has been assigned to overlapping plot segments. (requirements) Cover the supplied region exactly once, without gaps or duplicated passages. Segments must be mutually exclusive and remain in source order. Start a new segment only when there is a meaningful change in the immediate goal, setting, interaction, or outcome. Return a parsimonious set of segments with exact first-sentence anchors. |
| Character Enrichment | (intro) Generate compact character details for each supplied character in a finalized plot. (requirements) Use only the plot summary and the supplied plot text. For every character, generate a short description of identity, social position, or relevant relationships, together with a concise account of the character’s actions, decisions, intentions, or experiences in this plot. Do not use outside knowledge or information from later plots. Preserve the supplied canonical names and return strict JSON. |
| Alias Grouping | (intro) Group character names that refer to the same person and select a canonical name. (requirements) Merge formal names, honorifics, nicknames, and diminutives only when the identity is supported. Do not merge family members merely because they share a surname or title. If a name is genuinely ambiguous, place it in the unresolved list rather than guessing. Every input name must appear exactly once in either a group or the unresolved list. |

| Prompt | Template and requirements |
|---|---|
| Scene Splitting | (intro) Split a finalized plot into consecutive scenes representing continuous interactions in one setting. (requirements) Scenes must jointly cover the entire plot text without gaps or overlaps. Start a new scene when the setting changes or the interaction shifts to a different focus. For each scene, provide a description, canonical participants, relationship context, and the exact first sentence used to locate the scene in the source text. |
| T-A-O Extraction | (intro) Extract character behavior trajectories as Thought–Action–Observation loops from the supplied plot text. (requirements) An action is a decision-bearing behavior for which the character has plausible alternatives. Include consequential decisions, decisional speech such as refusal, persuasion, promise, deception, or threat, and deliberate silence or non-intervention. Exclude passive information exchange, routine movements, decorative gestures, and actions with no meaningful character choice. Each step must contain exactly one atomic decision. Thought is written from the character’s first-person perspective and must be grounded in the source text. Action describes the performed behavior or preserves a direct quotation when applicable. Observation records only reactions or environmental changes perceptible to the character; omniscient narration and later events are prohibited. For every behavior, generate exactly three situationally plausible but character-inconsistent alternatives. Mark a behavior as critical only when the character has a reasonable alternative and the selected behavior changes a persistent state or a future situational possibility. Record the scene’s actual time and supporting evidence, rather than dates mentioned only in plans, memories, or documents. Return strict JSON only. |

|---|---|
| Criticality Locator | (intro) Locate later plots and scenes that may contain evidence of the long-term consequences of a candidate critical behavior. (requirements) Use only the supplied event ledger and later scenes. Do not select the candidate’s own scene, an earlier scene, or a scene that merely repeats its wording or emotional tone. Return at most three supporting scene identifiers and a concise explanation of the possible downstream consequence. Return an empty list when no later evidence can be identified. |
| Criticality Verifier | (intro) Independently verify whether a candidate behavior should retain its critical-behavior label. (requirements) Keep a candidate only when the supplied later evidence contains a concrete event, relationship change, decision, or consequence that could plausibly differ under another reasonable choice. Every retained case must cite at least one supporting scene and action identifier. Vague plot importance, current-scene mood, or repeated wording does not constitute evidence. Return keep or downgrade in strict JSON. |
| Scene-Time Relabeling | (intro) Re-annotate the time at which the actions and dialogue in each scene actually occur. (requirements) Use only explicit or directly grounded evidence from the original plot text. A future appointment, a remembered event, or a date on a document is not automatically the time of the current scene. If the scene time is not established, return null for both the time label and its evidence. |
| Timeline Anomaly Detection | (intro) Detect confident cases in which the story-time order of scenes differs from their textual presentation order. (requirements) Treat textual order as the default timeline. Report only scenes or contiguous scene blocks whose primary actions and dialogue clearly occur earlier in story time. Do not move a scene merely because it contains a recollection, discussion of a past event, or a future plan. Return proposed moves and uncertain cases separately. |
| Timeline Review | (intro) Independently review each proposed timeline adjustment against the original plot text. (requirements) Check both the moved block and its insertion neighborhood. Return accept only when the boundaries and insertion point are supported, reject when the textual order should be preserved or evidence is insufficient, and modify when a different move is required. Provide source-grounded reasoning for every decision. |
| Entity Resolution | (intro) Resolve source-level character names into persistent character entities. (requirements) Group names only when the supplied time-ordered appearances establish that they refer to the same person. Do not merge people based only on shared surnames, titles, gender, or proximity. Every source name must appear exactly once in an entity group or in the unresolved list. Prefer conservative unresolved assignments to unsupported merges. |

|---|---|
| Profile Initialization | (intro) Construct the initial dynamic profile of a character immediately before the character’s first recorded behavior. (requirements) Use only the pre-action character description. Do not use the first action, later events, future relationships, or outside knowledge of the novel. Summarize the character’s supported identity, social position, temperament, interaction style, current relationships, and relevant lived experience in a compact profile. Return an evidence assessment together with the profile. |
| Profile Update | (intro) Update a character profile after a valid critical behavior and the accumulated actions since the previous profile version. (requirements) Set changed to true only when the action window causes a durable change in identity, social position, stable attitudes, important relationships, goals, self-understanding, or relevant lived experience. Repeated or temporary behavior does not require a new version. When changed=false , return a null profile. When changed=true , rewrite the complete current profile rather than producing a chronological action log. Do not use future events or counterfactual alternatives. |

|---|---|
| Counterfactual Rewriting | (intro) Rewrite the initially generated counterfactual behaviors for a source behavior. (requirements) The three alternatives must remain plausible responses to the same scene while violating the target character’s personality, values, goals, or behavioral style. Match the real behavior in length, structural form, speech format, register, and degree of formality. Preserve a quotation for dialogue behaviors and avoid quotations for non-dialogue behaviors. The alternatives must not be simple paraphrases and should differ along distinct behavioral dimensions. Return exactly three independent strings in strict JSON. |
| Record Anonymization | (intro) Replace person names in a dataset record with consistent anonymous character identifiers. (requirements) Identify every person-name form appearing in the record, including full names, nicknames, abbreviations, possessives, and title–name combinations. Map forms referring to the same person to the same Character N , ordered by first appearance. Preserve place names, animal names, relational terms, structural identifiers, and labels required for evaluation. Return a strict JSON name map. |

| Character Context | (intro) You are role-playing as the target character. Decide what the character will do next based on the supplied character profile, memories, and current scene. (requirements) Treat the provided Character Profile, Long-term Memory, Recent Memory, and Current Scene as the complete and authoritative history for the task. Do not rely on prior knowledge of the original novel, reconstruct omitted events, or infer future developments. The profile describes the current character state; long-term memory contains validated key behaviors; recent memory provides local behavioral context; and the current scene contains the situation immediately before the target behavior. During training, the source behavior is provided as chosen and one counterfactual behavior is provided as rejected . The model is trained to prefer the source behavior while also increasing its conditional likelihood under the auxiliary generation loss. |

| Next-Behavior Selection | (intro) Choose the action that the target character would most likely take next. (requirements) Use only the supplied Character Profile, Long-term Memory, Recent Memory, and Current Scene. Do not use prior knowledge of the original novel or any event that occurs after the target behavior. Four candidate behaviors are provided, including one source behavior and three counterfactual alternatives. Output exactly one letter: A , B , C , or D . Do not provide an explanation or any additional text. |
| Context Ablations | (intro) Evaluate the effect of individual character-information sources on next-behavior selection. (requirements) Use the same selection prompt while selectively removing the book identity, character profile, long-term memory, recent memory, or both profile and memory. All other scene and option information remains unchanged. The model must follow the same single-letter output constraint in every condition. |
