# User Profile Scoring(技术计划 · V1.2)
|
||||
|
||||
## 1. 计划目标
|
||||
|
||||
在**客户端(TypeScript)**实现一个可复用的“用户画像计算”模块:
|
||||
|
||||
- **输入**:Onboarding 问卷答案(每题**可跳过**;字段可缺失/为 `null`)
|
||||
- **输出**:严格符合 `spec_kit/User Profile Scoring/spec.md`(V1.2)的用户画像对象(含 `profile_answered`、四维度字段、`profile_confidence`)
|
||||
- **硬规则**:输出一份“下游可直接执行/可观测”的硬规则结果,用于推荐/Push/Widget 统一复用(对齐 V1.2 规则语义)
|
||||
- **约束**:不抛异常、不报错;非法值按**跳过**处理
|
||||
|
||||
## 2. 默认技术决策(本计划采用)
|
||||
|
||||
- **实现位置**:`client/src/features/userProfileScoring/`
|
||||
- **语言**:TypeScript(纯函数为主,便于测试与跨端复用)
|
||||
- **时间与可测性**:允许调用方注入 `generatedAt/now`,默认使用 `new Date()`,保证可回归测试
|
||||
- **规则对齐来源**:
|
||||
- 画像与置信度:`设计说明文档/客戶端問卷打分規則.md`(V1.2)
|
||||
- 下游过滤语义:`设计说明文档/個性化推薦算法規則.md`(Hard Filter / `risk_flags` 语义)
|
||||
|
||||
## 3. 输入与输出契约(V1.2,含跳过)
|
||||
|
||||
### 3.1 输入:问卷答案(允许部分缺失/跳过)
|
||||
|
||||
定义输入类型 `QuestionnaireAnswersV1_2`(所有字段可选;也允许显式 `null`):
|
||||
|
||||
- `mom_stage?: "expecting" | "parenting" | "unknown" | null`
|
||||
- `emotion?: "low" | "overwhelmed" | "tired" | "neutral" | "calm" | "joyful" | null`
|
||||
- `context?: "family" | "work" | "relationship" | "friends" | "health" | null`
|
||||
- `need?: "emotional_support" | "parenting_pressure" | "self_worth" | "anxiety_relief" | "rest_balance" | null`
|
||||
|
||||
非法值处理策略:
|
||||
|
||||
- 字段存在但值不在枚举内:按**跳过**处理(归一化为 `undefined`),不抛错
|
||||
|
||||
### 3.2 输出:用户画像(严格对齐 spec.md V1.2)
|
||||
|
||||
输出 `UserProfileV1_2`,满足 `spec.md` 的字段与取值:
|
||||
|
||||
- `profile_version: "v1.2"`
|
||||
- `profile_source: "questionnaire"`
|
||||
- `profile_generated_at: string`(ISO8601)
|
||||
- `profile_confidence: number`(0–1)
|
||||
- `profile_answered: { stage: boolean; emotion: boolean; context: boolean; need: boolean }`
|
||||
- `stage: { expecting?: 0|1; parenting?: 0|1; unknown: 0|1 }`
|
||||
- 注:题目跳过时按安全策略输出 `unknown=1`
|
||||
- `emotion_score: number | null`
|
||||
- `context: Record<string, 1>`(稀疏 one-hot;题目跳过时为 `{}`)
|
||||
- `need: Record<string, 1>`(稀疏 one-hot;题目跳过时为 `{}`)
|
||||
|
||||
### 3.3 额外输出:硬规则(供下游直接执行/打点)
|
||||
|
||||
`spec.md` 要求“向下游暴露可直接执行的硬规则结果”,但不强制字段结构。本计划采用以下扩展字段(不破坏 `spec.md` 核心结构):
|
||||
|
||||
- `rule_hits: string[]`
|
||||
- 仅用于可观测/回归测试(例如 `["unsafe_for_emotion_low"]`)
|
||||
- `hard_rules: { ... }`
|
||||
- `forbidden_risk_flags: string[]`(对齐内容侧/推荐侧 `risk_flags` 名称)
|
||||
- `forbidden_content_predicates: Array<{ id: string; when_user: object; forbid_content: object }>`
|
||||
- 用于表达“需要同时看用户与内容字段才能执行”的规则(例如 unknown + 育儿压力 + 强个性化)
|
||||
|
||||
## 4. 跳过题目的处理策略(V1.2:安全优先 + 可观测)
|
||||
|
||||
> 目标:题目跳过时不报错;画像仍可计算;并通过 `conf_U` 与下游 `P_uncertainty` 思路自动降个性化/降风险。
|
||||
|
||||
- **mom_stage 跳过**:
|
||||
- 输出:`stage.unknown = 1`
|
||||
- `profile_answered.stage = false`
|
||||
- **emotion 跳过**:
|
||||
- 输出:`emotion_score = null`(不强行填 0.6,避免制造“伪精确画像”)
|
||||
- `profile_answered.emotion = false`
|
||||
- **context 跳过**:
|
||||
- 输出:`context = {}`
|
||||
- `profile_answered.context = false`
|
||||
- **need 跳过**:
|
||||
- 输出:`need = {}`
|
||||
- `profile_answered.need = false`
|
||||
|
||||
## 5. 画像计算规则(映射 + 置信度 + 硬规则)
|
||||
|
||||
### 5.1 映射规则(对齐 `客戶端問卷打分規則.md` V1.2)
|
||||
|
||||
- `mom_stage` → `stage.*`(one-hot;若跳过则 `unknown=1`)
|
||||
- `emotion` → `emotion_score`:
|
||||
- `low=0.0`,`overwhelmed=0.2`,`tired=0.4`,`neutral=0.6`,`calm=0.8`,`joyful=1.0`
|
||||
- 若跳过:`emotion_score = null`
|
||||
- `context` → 稀疏 one-hot:例如 `work` → `{ work: 1 }`;若跳过:`{}`
|
||||
- `need` → 稀疏 one-hot:例如 `rest_balance` → `{ rest_balance: 1 }`;若跳过:`{}`
|
||||
|
||||
### 5.2 置信度(`profile_confidence / conf_U`)计算(V1.2)
|
||||
|
||||
时间衰减(与 `spec.md` 一致):
|
||||
|
||||
- 0–7 天:`conf_time = 1.0`
|
||||
- 7–30 天:线性衰减到 `0.7`
|
||||
- 30 天以上:`conf_time = 0.5`
|
||||
|
||||
作答完整度因子(对齐 `客戶端問卷打分規則.md` V1.2):
|
||||
|
||||
- `answered_count = Σ I[profile_answered.* = true]`,`total_questions = 4`
|
||||
- `completion = answered_count / total_questions`
|
||||
- `completion_factor = 0.5 + 0.5 * completion`
|
||||
- `profile_confidence = clamp(conf_time * completion_factor, 0.2, 1.0)`
|
||||
|
||||
### 5.3 硬规则输出(对齐 V1.2)
|
||||
|
||||
本模块输出 `rule_hits` 与 `hard_rules`,用于下游先过滤、后打分:
|
||||
|
||||
1) **按用户状态映射到内容 `risk_flags` 的禁推**
|
||||
|
||||
- 若 `stage.unknown = 1`:
|
||||
- `rule_hits += ["unsafe_for_stage_unknown"]`
|
||||
- `hard_rules.forbidden_risk_flags += ["unsafe_for_stage_unknown"]`
|
||||
- 若 `stage.parenting = 1`:
|
||||
- `rule_hits += ["unsafe_for_stage_parenting"]`
|
||||
- `hard_rules.forbidden_risk_flags += ["unsafe_for_stage_parenting"]`
|
||||
- 若 `emotion_score !== null` 且 `emotion_score <= 0.2`:
|
||||
- `rule_hits += ["unsafe_for_emotion_low"]`
|
||||
- `hard_rules.forbidden_risk_flags += ["unsafe_for_emotion_low"]`
|
||||
|
||||
2) **跨维度产品规则(需要同时看用户与内容字段)**
|
||||
|
||||
- 若 `stage.unknown = 1`:
|
||||
- 增加一个可执行谓词,表达“禁推 育儿压力且高个性化内容”:
|
||||
- `when_user`: `{ stage_unknown: true }`
|
||||
- `forbid_content`: `{ need: "parenting_pressure", personalization_power: 1 }`
|
||||
- 该规则由下游在内容侧字段存在时执行(对齐 `spec.md` 7 与 `客戶端問卷打分規則.md` 6 的 V1.2 口径)
|
||||
|
||||
> 注:本模块不判断内容的 `personalization_power`(属于内容侧),只输出“可执行条件”。
|
||||
|
||||
## 6. 文件与目录规划(客户端)
|
||||
|
||||
在 `client/src/` 新增/调整:
|
||||
|
||||
- `client/src/features/userProfileScoring/types.ts`
|
||||
- `QuestionnaireAnswersV1_2` / `UserProfileV1_2` / 枚举联合类型
|
||||
- `client/src/features/userProfileScoring/scoring.ts`
|
||||
- `buildUserProfileFromQuestionnaire(answers, options): UserProfileV1_2 & { rule_hits; hard_rules }`
|
||||
- `computeTimeConfidence(generatedAt, now): number`
|
||||
- `normalizeAnswers(raw): QuestionnaireAnswersV1_2`(非法值 → 跳过)
|
||||
- `computeProfileAnswered(normalized): profile_answered`
|
||||
- `computeProfileConfidence(conf_time, profile_answered): number`
|
||||
- `client/src/features/userProfileScoring/index.ts`
|
||||
- 对外导出(供 Onboarding/推荐/Push 调用)
|
||||
|
||||
## 7. 测试计划(客户端可回归)
|
||||
|
||||
若工程未提供 `test` 脚本,建议补齐最小单元测试能力(只测纯函数):
|
||||
|
||||
- 新增 `vitest`(或 `jest`)为 devDependencies,并在 `client/package.json` 增加 `test` 脚本
|
||||
- 为 `buildUserProfileFromQuestionnaire` 增加用例(与 `spec.md` 第 10 章一致):
|
||||
- 映射正确性(完整作答)
|
||||
- 置信度时间衰减(0–7/7–30/30+)
|
||||
- 硬规则触发(`emotion_score<=0.2`、`stage.unknown`、`stage.parenting`)
|
||||
- 跳过场景(V1.2):
|
||||
- 全部跳过(输入 `{}`):`profile_answered` 全 false;`stage.unknown=1`;`emotion_score=null`;`context/need={}`;`profile_confidence=0.5`(当 conf_time=1 时)
|
||||
- 仅回答 1 题:验证 `completion_factor` 与 clamp(最小 0.2)逻辑正确
|
||||
|
||||
## 8. 实施步骤
|
||||
|
||||
1. 在 `client/src/features/userProfileScoring/` 增加类型定义与常量映射表(V1.2)
|
||||
2. 实现答案归一化(非法值按跳过;支持 `null/undefined`)
|
||||
3. 实现画像生成主函数(含 `profile_answered`、元信息生成、置信度计算)
|
||||
4. 实现硬规则命中与结构化输出(`forbidden_risk_flags` + `forbidden_content_predicates`)
|
||||
5. 补齐最小测试框架与单测(仅纯函数)
|
||||
6. Onboarding 流程完成处接入(后续任务):问卷提交后生成画像对象;持久化/上传由上层决定
|
||||
|
||||
## 9. 验收标准
|
||||
|
||||
- 任意问卷答案输入(含任意题跳过/非法值),都能生成符合 `spec.md`(V1.2)结构的用户画像对象(不抛错)
|
||||
- 输出包含:
|
||||
- V1.2 元信息(`profile_version/source/generated_at/confidence/profile_answered`)
|
||||
- 四维度字段(`stage/emotion_score/context/need`;允许跳过后的 `null/{}`)
|
||||
- `rule_hits` 与 `hard_rules`(供下游执行 Hard Filter 与打点)
|
||||
- 置信度:
|
||||
- 时间衰减符合 `spec.md` 6.2
|
||||
- 跳过越多 `profile_confidence` 越低(按 V1.2 完整度因子),并被 clamp 到 `[0.2, 1.0]`
|
||||
|
||||
## 10. 后续演进(不阻塞 V1.2)
|
||||
|
||||
- 支持 `context/need` 多选(输出仍为 one-hot,可多个 key=1)
|
||||
- 引入 `profile_source="mixed"`:行为信号修正 `emotion_score` 或补全缺失维度(保留 questionnaire 原始画像用于可观测)
|
||||
- 将硬规则输出进一步与推荐系统规则引擎 schema 对齐(使 `forbidden_content_predicates` 可直接落入规则引擎)

> 本组用例只验证 `profile_confidence` 计算是否符合第 6.2 节;其余字段可沿用任意合法输入。
|
||||
|
||||
#### 用例 C:0–7 天(不衰减)
|
||||
|
||||

||||
- `profile_generated_at = 2026-01-01T00:00:00Z`
|
||||
- `now = 2026-01-11T00:00:00Z`(第 10 天)

||||
|
||||
#### 用例 E:30 天以上(固定为 0.5)
|
||||
|
||||
- `profile_generated_at = 2026-01-01T00:00:00Z`
|
||||
- `now = 2026-02-15T00:00:00Z`
|
||||
|
||||
期望:`profile_confidence = 0.5`
|
||||
|
||||
### 10.4 硬规则触发用例(可选,但建议覆盖)
|
||||
|
||||
> 本节只验证“规则是否被触发”。由于第 7 节目前只规定了规则语义,未强约束硬规则输出字段结构,测试可用两种方式之一:
|
||||
>
|
||||
> - 方式 1:若实现提供 `hard_rules`(或同义字段),则断言其包含对应禁推项
|
||||
> - 方式 2:实现不提供结构化 `hard_rules` 时,至少应提供可观测的 `rule_hits`(字符串数组)用于下游与回归测试
|
||||
|
||||
#### 用例 F:emotion_score ≤ 0.2 禁推 joyful 调性
|
||||
|
||||
输入:
|
||||
|
||||
```json
|
||||
{
|
||||
"mom_stage": "expecting",
|
||||
"emotion": "overwhelmed",
|
||||
"context": "health",
|
||||
"need": "anxiety_relief"
|
||||
}
|
||||
```
|
||||
|
||||
期望:
|
||||
|
||||
- `emotion_score = 0.2`
|
||||
- 规则命中:`emotion_score ≤ 0.2` → 禁推高能量庆祝型(joyful 调性)内容
|
||||
|
||||
#### 用例 G:stage.unknown 禁推“育儿压力 + 高个性化”内容
|
||||
|
||||
输入:
|
||||
|
||||
```json
|
||||
{
|
||||
"mom_stage": "unknown",
|
||||
"emotion": "calm",
|
||||
"context": "family",
|
||||
"need": "parenting_pressure"
|
||||
}
|
||||
```
|
||||
|
||||
期望:
|
||||
|
||||
- `stage.unknown = 1`
|
||||
- 规则命中:`stage.unknown = 1` → 下游禁推满足以下条件的内容:
|
||||
- `need: parenting_pressure`
|
||||
- `personalization_power = 1`

>
|
||||
> 规则目标:在客户端实现“问卷答案(可跳过)→ 用户画像(含 profile_answered/confidence)+ 硬规则输出”,供推荐/Push/Widget 复用。

## 任务状态说明
|
||||
|
||||
- `[ ]`:未开始
|

- `[x]`:已完成
|
||||

|
||||
|
||||
## A. 代码实现(客户端 TypeScript 模块)
|
||||
|
||||
### A1. 建立目录与导出入口
|
||||
|
||||
- [x] 在 `client/src/features/` 下新增目录 `userProfileScoring/`
|
||||
- **验收**:目录存在,且后续文件均放入该目录
|
||||
- [x] 新建 `client/src/features/userProfileScoring/index.ts`
|
||||
- **内容**:对外导出主函数与类型(避免上层直接深路径 import)
|
||||
- **验收**:上层可仅从 `.../userProfileScoring` 引入
|
||||
|
||||
### A2. 定义类型与枚举(V1.2)
|
||||
|
||||
- [x] 新建 `client/src/features/userProfileScoring/types.ts`
|
||||
- **定义输入类型**:`QuestionnaireAnswersV1_2`
|
||||
- 字段允许 `undefined`/`null`:`mom_stage/emotion/context/need`
|
||||
- **定义输出类型**:`UserProfileV1_2`
|
||||
- 固定 `profile_version: "v1.2"`、`profile_source: "questionnaire"`
|
||||
- `profile_answered`:`{ stage; emotion; context; need }`
|
||||
- `emotion_score: number | null`
|
||||
- `context/need: Record<string, 1>`(稀疏 one-hot;跳过为 `{}`)
|
||||
- **定义扩展输出类型**:`UserProfileV1_2_Extended`
|
||||
- `rule_hits: string[]`
|
||||
- `hard_rules: { forbidden_risk_flags: string[]; forbidden_content_predicates: ... }`
|
||||
- **验收**:类型字段与 `spec_kit/User Profile Scoring/spec.md`(V1.2)一致
|
||||
|
||||
### A3. 实现答案归一化(非法值按跳过)
|
||||
|
||||
- [x] 新建 `client/src/features/userProfileScoring/scoring.ts`
|
||||
- [x] 实现 `normalizeAnswers(raw): QuestionnaireAnswersV1_2`
|
||||
- **规则**:
|
||||
- 值不在枚举内 → 归一化为 `undefined`
|
||||
- `null` 保留为 `null`(表示显式跳过/无值)
|
||||
- **验收**:任意输入不抛错;输出只包含合法枚举/`undefined`/`null`
|
||||
|
||||
### A4. 计算 profile_answered(V1.2)
|
||||
|
||||
- [x] 实现 `computeProfileAnswered(normalized)`:
|
||||
- `stage = (mom_stage !== undefined && mom_stage !== null)`
|
||||
- `emotion/context/need` 同理
|
||||
- **验收**:与 `spec.md` 6.1.1 一致;可区分“缺失/跳过”与“明确作答”
|
||||
|
||||
### A5. 计算时间衰减 conf_time
|
||||
|
||||
- [x] 实现 `computeTimeConfidence(generatedAt, now): number`
|
||||
- **规则**(与 `spec.md` 6.2 一致):
|
||||
- 0–7 天:1.0
|
||||
- 7–30 天:线性衰减到 0.7
|
||||
- 30 天以上:0.5
|
||||
- **验收**:给定固定时间输入,输出符合分段规则(允许浮点误差)
|
||||
|
||||
### A6. 计算 profile_confidence(V1.2 完整度因子 + clamp)
|
||||
|
||||
- [x] 实现 `computeProfileConfidence(conf_time, profile_answered): number`
|
||||
- **规则**(与 `设计说明文档/客戶端問卷打分規則.md` V1.2 一致):
|
||||
- `answered_count = Σ I[profile_answered.* = true]`
|
||||
- `completion = answered_count / 4`
|
||||
- `completion_factor = 0.5 + 0.5 * completion`
|
||||
- `conf = clamp(conf_time * completion_factor, 0.2, 1.0)`
|
||||
- **验收**:
|
||||
- 全部跳过且 `conf_time=1` → `conf=0.5`
|
||||
- 全部作答且 `conf_time=1` → `conf=1.0`
|
||||
- 极端情况下不会低于 0.2 / 高于 1.0
|
||||
|
||||
### A7. 生成四维度画像字段(含跳过策略)
|
||||
|
||||
- [x] 实现 `buildUserProfileFromQuestionnaire(answers, options)`
|
||||
- **元信息**:
|
||||
- `profile_version="v1.2"`
|
||||
- `profile_source="questionnaire"`
|
||||
- `profile_generated_at`:允许注入;默认 `new Date().toISOString()`
|
||||
- **stage**:
|
||||
- 若 `mom_stage` 缺失/为 `null`:按安全策略输出 `stage.unknown=1`
|
||||
- 若为枚举:对应 one-hot
|
||||
- **emotion_score**:
|
||||
- 若跳过:`null`
|
||||
- 否则按映射表输出数值
|
||||
- **context/need**:
|
||||
- 若跳过:输出 `{}`
|
||||
- 否则输出稀疏 one-hot(例如 `{ work: 1 }`)
|
||||
- **验收**:与 `spec.md` 4.2/5.x/6.x 一致
|
||||
|
||||
### A8. 硬规则与可观测输出(rule_hits / hard_rules)
|
||||
|
||||
- [x] 在 `buildUserProfileFromQuestionnaire` 内生成 `rule_hits` 与 `hard_rules`
|
||||
- **risk_flags 映射规则**(与 `spec.md` 7 一致):
|
||||
- `stage.unknown=1` → `unsafe_for_stage_unknown`
|
||||
- `stage.parenting=1` → `unsafe_for_stage_parenting`
|
||||
- `emotion_score !== null && emotion_score<=0.2` → `unsafe_for_emotion_low`
|
||||
- **跨维度规则谓词**(与 `spec.md` 7、客户端规则 V1.2 一致):
|
||||
- 若 `stage.unknown=1`:追加谓词
|
||||
- `id`: 建议 `unknown_block_parenting_pressure_personalized`
|
||||
- `when_user`: `{ stage_unknown: true }`
|
||||
- `forbid_content`: `{ need: "parenting_pressure", personalization_power: 1 }`
|
||||
- **验收**:
|
||||
- 输出结构稳定
|
||||
- 不依赖内容侧字段(本模块只输出“可执行条件”)
|
||||
|
||||

|
||||
|
||||
## B. 单元测试(只测纯函数)
|
||||
|
||||
> 若当前工程暂不引入测试框架,可先把测试用例写成“可执行脚本/最小断言”;但建议最终落地 `vitest` 或 `jest`。
|
||||
|
||||
### B1. 建立测试框架(可选但建议)
|
||||
|
||||
- [x] 若 `client/` 尚无测试:引入 `vitest`(或 `jest`)并添加 `test` 脚本
|
||||
- **验收**:能在本机运行测试并输出结果
|
||||
|
||||
### B2. 覆盖 spec.md 的关键用例
|
||||
|
||||
- [x] 用例:完整作答映射正确(对应 `spec.md` 用例 A/B)
|
||||
- [x] 用例:时间衰减(对应 `spec.md` 用例 C/D/E)
|
||||
- [x] 用例:全部跳过 `{}`(对应 `spec.md` 用例 A2)
|
||||
- 断言:`profile_answered` 全 false;`stage.unknown=1`;`emotion_score=null`;`context/need={}`;`profile_confidence=0.5`(当 conf_time=1)
|
||||
- [x] 用例:硬规则命中
|
||||
- `emotion_score<=0.2` → 含 `unsafe_for_emotion_low`
|
||||
- `stage.parenting=1` → 含 `unsafe_for_stage_parenting`
|
||||
- `stage.unknown=1` → 含 `unsafe_for_stage_unknown` 且带跨维度谓词
|
||||
|
||||
---
|
||||
|
||||
## C. 接入与文档回写(后续任务)
|
||||
|
||||
- [ ] Onboarding 提交问卷处接入本模块(调用 `buildUserProfileFromQuestionnaire`)
|
||||
- **验收**:提交后能生成并持久化/上传画像对象(具体存储策略由上层决定)
|
||||
- [ ] 在推荐/Push/Widget 侧消费 `hard_rules`
|
||||
- **验收**:Hard Filter 在打分前执行;且能使用跨维度谓词表达 unknown+育儿压力强个性化禁推
