-## 核心任务背景
+## Core Task Background
-我们正在构建一个**社交媒体舆论模拟系统**。在这个系统中：
+We are building a **social media public opinion simulation system**. In this system:
- 每个实体都是一个可以在社交媒体上发声、互动、传播信息的"账号"或"主体"
+- Each entity is an "account" or "actor" that can post, interact, and spread information on social media
- 实体之间会相互影响、转发、评论、回应
+- Entities influence each other through reposts, comments, and responses
- 我们需要模拟舆论事件中各方的反应和信息传播路径
+- We need to simulate the reactions and information propagation paths of various parties in public opinion events
-因此，**实体必须是现实中真实存在的、可以在社媒上发声和互动的主体**：
+Therefore, **entities must be real-world actors that can post and interact on social media**:
-**可以是**：
+**Can be**:
- 具体的个人（公众人物、当事人、意见领袖、专家学者、普通人）
+- Specific individuals (public figures, parties involved, opinion leaders, experts, ordinary people)
- 公司、企业（包括其官方账号）
+- Companies and enterprises (including their official accounts)
- 组织机构（大学、协会、NGO、工会等）
+- Organizations (universities, associations, NGOs, unions, etc.)
- 政府部门、监管机构
+- Government departments and regulatory agencies
- 媒体机构（报纸、电视台、自媒体、网站）
+- Media organizations (newspapers, TV stations, self-media, websites)
- 社交媒体平台本身
+- Social media platforms themselves
- 特定群体代表（如校友会、粉丝团、维权群体等）
+- Representatives of specific groups (e.g., alumni associations, fan groups, advocacy groups, etc.)
-**不可以是**：
+**Cannot be**:
- 抽象概念（如"舆论"、"情绪"、"趋势"）
+- Abstract concepts (e.g., "public opinion", "emotion", "trend")
- 主题/话题（如"学术诚信"、"教育改革"）
+- Topics/themes (e.g., "academic integrity", "education reform")
- 观点/态度（如"支持方"、"反对方"）
+- Viewpoints/attitudes (e.g., "supporters", "opponents")

-## 设计指南（极其重要！）
+## Design Guidelines (Extremely Important!)
-### 1. 实体类型设计 - 必须严格遵守
+### 1. Entity Type Design - Must Be Strictly Followed
-**数量要求：必须正好10个实体类型**
+**Quantity requirement: Exactly 10 entity types**
-**层次结构要求（必须同时包含具体类型和兜底类型）**：
+**Hierarchy requirements (must include both specific types and fallback types)**:
-你的10个实体类型必须包含以下层次：
+Your 10 entity types must include the following levels:
-A. **兜底类型（必须包含，放在列表最后2个）**：
+A. **Fallback types (must be included, placed as the last 2 in the list)**:
-   - `Person`: 任何自然人个体的兜底类型。当一个人不属于其他更具体的人物类型时，归入此类。
+   - `Person`: Fallback type for any individual person. When a person doesn't fit other more specific person types, they go here.
-   - `Organization`: 任何组织机构的兜底类型。当一个组织不属于其他更具体的组织类型时，归入此类。
+   - `Organization`: Fallback type for any organization. When an organization doesn't fit other more specific organization types, it goes here.
-B. **具体类型（8个，根据文本内容设计）**：
+B. **Specific types (8 types, designed based on text content)**:
-   - 针对文本中出现的主要角色，设计更具体的类型
+   - Design more specific types for the main roles appearing in the text
-   - 例如：如果文本涉及学术事件，可以有 `Student`, `Professor`, `University`
+   - For example: if the text involves academic events, you can have `Student`, `Professor`, `University`
-   - 例如：如果文本涉及商业事件，可以有 `Company`, `CEO`, `Employee`
+   - For example: if the text involves business events, you can have `Company`, `CEO`, `Employee`
-**为什么需要兜底类型**：
+**Why fallback types are needed**:
- 文本中会出现各种人物，如"中小学教师"、"路人甲"、"某位网友"
+- Various people appear in the text, such as "elementary school teachers", "bystanders", "random netizens"
- 如果没有专门的类型匹配，他们应该被归入 `Person`
+- If there is no specific type match, they should be classified under `Person`
- 同理，小型组织、临时团体等应该归入 `Organization`
+- Similarly, small organizations, temporary groups, etc. should be classified under `Organization`
-**具体类型的设计原则**：
+**Design principles for specific types**:
- 从文本中识别出高频出现或关键的角色类型
+- Identify high-frequency or key role types from the text
- 每个具体类型应该有明确的边界，避免重叠
+- Each specific type should have clear boundaries to avoid overlap
- description 必须清晰说明这个类型和兜底类型的区别
+- The description must clearly explain how this type differs from the fallback type
-### 2. 关系类型设计
+### 2. Relationship Type Design
- 数量：6-10个
+- Quantity: 6-10
- 关系应该反映社媒互动中的真实联系
+- Relationships should reflect real connections in social media interactions
- 确保关系的 source_targets 涵盖你定义的实体类型
+- Ensure the source_targets of relationships cover the entity types you defined
-### 3. 属性设计
+### 3. Attribute Design
- 每个实体类型1-3个关键属性
+- 1-3 key attributes per entity type
- **注意**：属性名不能使用 `name`、`uuid`、`group_id`、`created_at`、`summary`（这些是系统保留字）
+- **Note**: Attribute names cannot use `name`, `uuid`, `group_id`, `created_at`, `summary` (these are system reserved words)
- 推荐使用：`full_name`, `title`, `role`, `position`, `location`, `description` 等
+- Recommended: `full_name`, `title`, `role`, `position`, `location`, `description`, etc.

-   - 在报告中使用引用格式展示这些预测，例如：
+   - Use quote format in the report to display these predictions, for example:
-     > "某类人群会表示：原文内容..."
+     > "A certain group would say: original content..."
-   - 这些引用是模拟预测的核心证据
+   - These quotes are the core evidence of simulation predictions
-3. 【语言一致性 - 引用内容必须翻译为报告语言】
+3. [Language Consistency - Report Language]
-   - 工具返回的内容可能包含英文或中英文混杂的表述
+   - Tool-returned content may contain mixed languages
-   - 如果模拟需求和材料原文是中文的，报告必须全部使用中文撰写
+   - The report should be written in a language consistent with the simulation requirement
-   - 当你引用工具返回的英文或中英混杂内容时，必须将其翻译为流畅的中文后再写入报告
+   - When quoting tool-returned content, translate it into the report language for fluency
-   - 翻译时保持原意不变，确保表述自然通顺

+### Basic Principles (for reference only, adjust flexibly based on the specific event and participant groups):
- 用户群体为中国人，需符合北京时间作息习惯
+- The user base follows Chinese timezone daily routines (Beijing Time, UTC+8)
- 凌晨0-5点几乎无人活动（活跃度系数0.05）
+- 0-5 AM: almost no activity (activity coefficient 0.05)
- 早上6-8点逐渐活跃（活跃度系数0.4）
+- 6-8 AM: gradually increasing activity (activity coefficient 0.4)
- 工作时间9-18点中等活跃（活跃度系数0.7）
+- 9 AM - 6 PM: moderate activity during work hours (activity coefficient 0.7)
- 晚间19-22点是高峰期（活跃度系数1.5）
+- 7-10 PM: peak hours (activity coefficient 1.5)
- 23点后活跃度下降（活跃度系数0.5）
+- After 11 PM: activity decreases (activity coefficient 0.5)
- 一般规律：凌晨低活跃、早间渐增、工作时段中等、晚间高峰
+- General pattern: low activity at dawn, gradual increase in morning, moderate during work, peak in evening
- **重要**：以下示例值仅供参考，你需要根据事件性质、参与群体特点来调整具体时段
+- **Important**: The example values below are for reference only. Adjust time periods based on the nature of the event and characteristics of participants.
-  - 例如：学生群体高峰可能是21-23点；媒体全天活跃；官方机构只在工作时间
+  - Example: Student groups may peak at 9-11 PM; media is active all day; government agencies only during work hours
-  - 例如：突发热点可能导致深夜也有讨论，off_peak_hours 可适当缩短
+  - Example: Breaking news may cause late-night discussions, off_peak_hours can be shortened
