- # 输入信息

- - **<原始问题>**:用户的初始查询问题,代表用户的真实需求意图。
- - **<平台sug词条>**:待评估的词条,可能是单个或多个作用域的组合
- ---
- # 核心约束
- ## 维度独立性声明
- 【严格约束】本评估**仅评估动机意图维度**:
- - **只评估** 用户"想要做什么",即原始问题的行为意图和目的
- - 核心是 **动词**:获取、学习、拍摄、制作、寻找等
- - 包括:核心动作 + 使用场景 + 最终目的
- - **评估重点**:动作本身及其语义方向
- **禁止使用"主题相关"作为评分依据**:评分理由中不得出现"主题"、"内容"、"话题"等词
- ---
- # 作用域与动作意图
- ## 什么是作用域?
- **作用域 = 动机层 + 对象层 + 场景层**
- ## 动作意图的识别
- ### 方法1: 显性动词直接提取
- 当原始问题明确包含动词时,直接提取
- 示例:
- "如何获取素材" → 核心动机 = "获取"
- "寻找拍摄技巧" → 核心动机 = "寻找"(或"学习")
- "制作视频教程" → 核心动机 = "制作"
- ### 方法2: 隐性动词语义推理
- 当原始问题没有显性动词时,需要结合上下文推理
- 如果原始问题是纯名词短语,无任何动作线索:
- → 核心动机 = 无法识别
- → 在此情况下,动机维度得分应为 0。
- 示例:
- "摄影" → 无法识别动机,动机维度得分 = 0
- "川西风光" → 无法识别动机,动机维度得分 = 0
- ---
- # 部分作用域的处理
- ## 情况1:sug词条是原始问题的部分作用域
- 当sug词条只包含原始问题的部分作用域时,需要判断:
- 1. sug词条是否包含动作意图
- 2. 如果包含,动作是否匹配
- **示例**:
- ```
- 原始问题:"川西旅行行程规划"
- - 完整作用域:规划(动作)+ 旅行行程(对象)+ 川西(场景)
- Sug词条:"川西旅行"
- - 包含作用域:旅行(部分对象)+ 川西(场景)
- - 缺失作用域:规划(动作)
- - 动作意图评分:0(无动作意图)
- ```
- **评分原则**:
- - 如果sug词条缺失动机层(动作) → 动作意图得分 = 0
- - 如果sug词条包含动机层 → 按动作匹配度评分
- ---
- # 评分标准
- ## 【正向匹配】
- ### +0.9~1.0:核心动作完全一致
- **示例**:
- - "规划旅行行程" vs "安排旅行路线" → 0.98
- - 规划≈安排,语义完全一致
- - "获取素材" vs "下载素材" → 0.97
- - 获取≈下载,语义完全一致
- - 特殊规则: 如果sug词的核心动作是原始问题动作的**具体化子集**,也判定为完全一致
- 例: 原始问题"扣除猫咪主体的方法" vs sug词"扣除猫咪眼睛的方法"(子集但目的一致
- **注意**:此处不考虑对象和场景是否一致,只看动作本身
- ###+0.75~0.95: 核心动作语义相近或为同义表达
- - 例: 原始问题"如何获取素材" vs sug词"如何下载素材"
- - 同义词对: 获取≈下载≈寻找, 技巧≈方法≈教程≈攻略
- ### +0.50~0.75:动作意图相关
- **判定标准**:
- - 动作是实现原始意图的相关路径
- - 或动作是原始意图的前置/后置步骤
- **示例**:
- - "获取素材" vs "管理素材" → 0.65
- - 管理是获取后的相关步骤
- - "规划行程" vs "预订酒店" → 0.60
- - 预订是规划的具体实施步骤
- ### +0.25~0.50:动作意图弱相关
- **判定标准**:
- - 动作在同一大类但方向不同
- - 或动作有间接关联
- **示例**:
- - "学习摄影技巧" vs "欣赏摄影作品" → 0.35
- - 都与摄影有关,但学习≠欣赏
- - "规划旅行" vs "回忆旅行" → 0.30
- - 都与旅行有关,但方向不同
- ---
- ## 【中性/无关】
- ### 0:无动作意图或动作完全无关
- **适用场景**:
- 1. 原始问题或sug词条无法识别动作
- 2. 两者动作意图完全无关
- **示例**:
- - "如何获取素材" vs "摄影器材" → 0
- - sug词条无动作意图
- - "川西风光" vs "风光摄影作品" → 0
- - 原始问题无动作意图
- **理由模板**:
- - "sug词条无明确动作意图,无法评估动作匹配度"
- - "原始问题无明确动作意图,动作维度得分为0"
- ---
- ## 【负向偏离】
- ### -0.2~-0.05:动作方向轻度偏离
- **示例**:
- - "学习摄影技巧" vs "销售摄影课程" → -0.10
- - 学习 vs 销售,方向有偏差
- ### -0.5~-0.25:动作意图明显冲突
- **示例**:
- - "获取免费素材" vs "购买素材" → -0.35
- - 获取免费 vs 购买,明显冲突
- ### -1.0~-0.55:动作意图完全相反
- **示例**:
- - "下载素材" vs "上传素材" → -0.70
- - 下载 vs 上传,方向完全相反
- ---
- ## 得分为零的原因(语义判断)
- 当动机维度得分为 0 时,需要在 `得分为零的原因` 字段中选择以下之一:
- - **"原始问题无动机"**:原始问题是纯名词短语,无法识别任何动作意图
- - **"sug词条无动机"**:sug词条中不包含任何动作意图
- - **"动机不匹配"**:双方都有动作,但完全无关联
- - **"不适用"**:得分不为零时使用此默认值
- ---

- +0.75~0.95: 核心主体匹配,存在限定词匹配
- - 例: 原始问题"川西秋季风光摄影素材" vs sug词"川西风光摄影素材"(缺失"秋季")
- +0.5~0.75: 核心主体匹配,无限定词匹配或合理泛化
- - 例: 原始问题"川西秋季风光摄影素材" vs sug词"四川风光摄影"
- +0.3~0.5: 核心主体匹配,但限定词缺失或存在语义错位
- - 特别注意"语义身份"差异,主体词出现但上下文语义不同

- · "猫咪的XX行为"(猫咪是行为者)
- · vs "用猫咪表达XX的梗图"(猫咪是媒介)

- +0.2~0.3: 主体词不匹配,限定词缺失或错位
- - 例: 原始问题"川西秋季风光摄影素材" vs sug词"风光摄影入门"
- +0.05~0.2: 主体词过度泛化或仅抽象相似
- - 例: sug词是通用概念,原始问题是特定概念
- sug词"每日计划"(通用)vs 原始问题 "川西旅行行程"(特定)
- → 评分:0.08
- 【中性/无关】
- 0: 类别明显不同,没有明确目的,无明确关联
- - 例: 原始问题"川西秋季风光摄影素材" vs sug词"人像摄影素材"
- - 例: 原始问题无法识别动机 且 sug词也无明确动作 → 0

- 延伸词是否帮助sug词条更接近原始问题的完整作用域?
- ### 维度2:目的达成度
- 延伸词是否促进原始问题核心目的的达成?
- ---
- ####类型1:作用域增强型
- **定义**:延伸词是原始问题核心目的,或补全关键作用域
- **得分范围**:+0.12~+0.20
- **判定标准**:
- - 使sug词条更接近原始问题的完整需求
- ---
- ####类型2:作用域辅助型
- **定义**:延伸词对核心目的有辅助作用,但非必需
- **得分范围**:+0.05~+0.12
- **判定标准**:
- - sug词条更丰富但不改变原始需求核心
- ---
- ####类型3:作用域无关型
- **定义**:延伸词与核心目的无实质关联
- **得分**:0
- **示例**:
- - 原始:"如何拍摄风光" + 延伸词:"相机品牌排行"
- - 评分:0
- - 理由:品牌排行与拍摄技巧无关
- ---
- ####类型4:作用域稀释型(轻度负向)
- **定义**:延伸词稀释原始问题的聚焦度,降低内容针对性
- **得分范围**:-0.08~-0.18
- **判定标准**:
- - 引入无关信息,分散注意力
- - 降低内容的专注度和深度
- - 使sug词条偏离原始问题的核心
- **示例**:
- - 原始:"专业风光摄影技巧" + 延伸词:"手机拍照"
- - 评分:-0.12
- - 理由:手机拍照与专业摄影需求不符,稀释专业度
- - 原始:"川西深度游攻略" + 延伸词:"周边一日游"
- - 评分:-0.10

- # 特殊情况处理
- ## 情况1:多个延伸词同时存在
- **处理方法**:分别评估每个延伸词,然后综合
- **综合规则**:
- ```
- 延伸词总得分 = Σ(每个延伸词得分) / 延伸词数量
- 考虑累积效应:
- - 多个增强型延伸词 → 总分可能超过单个最高分,但上限+0.25
- - 正负延伸词并存 → 相互抵消
- - 多个冲突型延伸词 → 总分下限-0.60
- ```
- **示例**:
- ```
- 原始:"川西旅行行程"
- Sug词条:"川西旅行行程住宿美食推荐"
- 延伸词识别:
- - "住宿推荐"→ 增强型,+0.18
- - "美食推荐"→ 辅助型,+0.10
- 总得分:(0.18 + 0.10) / 2 = 0.14
- ```
- ---
- ## 情况2:无延伸词
- **处理方法**:
- ```
- IF sug词条无延伸词:
- 延伸词得分 = 0
- 理由:"sug词条未引入延伸词,所有词汇均属于原始问题作用域范围"
- ```
- ---
- ## 情况3:延伸词使sug词条更接近原始问题
- **特殊加成**:
- ```
- IF 延伸词是原始问题隐含需求的显式化:
- → 额外加成 +0.05
- ```
- **示例**:
- ```
- 原始:"川西旅行" (隐含需要行程规划)
