🔧 核心模块实现
1. 意图识别模块
// intent_classifier.js
class IntentClassifier {
constructor() {
this.intents = {
'faq_query': ['怎么', '如何', '什么', '为什么'],
'service_request': ['办理', '申请', '开通', '注销'],
'complaint': ['投诉', '不满', '问题', '故障'],
'feedback': ['建议', '意见', '好评', '差评']
};
}
classify(message) {
const scores = {};
for (const [intent, keywords] of Object.entries(this.intents)) {
scores[intent] = this.calculateScore(message, keywords);
}
const bestIntent = Object.keys(scores).reduce((a, b) =>
scores[a] > scores[b] ? a : b
);
return {
intent: bestIntent,
confidence: scores[bestIntent],
entities: this.extractEntities(message)
};
}
calculateScore(text, keywords) {
let score = 0;
keywords.forEach(keyword => {
if (text.includes(keyword)) {
score += 1;
}
});
return score / keywords.length;
}
}
2. 知识库管理系统
# knowledge_base_schema.yaml
collections:
faq:
fields:
- name: question
type: text
analyzer: chinese
- name: answer
type: text
- name: category
type: keyword
- name: tags
type: keyword[]
- name: created_at
type: datetime
indexes:
- name: category_idx
fields: [category]
- name: tags_idx
fields: [tags]
3. 对话状态管理
// dialog_manager.js
class DialogManager {
constructor() {
this.sessions = new Map(); // 用户会话状态
this.contextWindow = 10; // 上下文窗口大小
}
async processMessage(userId, message) {
// 获取用户会话
let session = this.getSession(userId);
// 更新对话历史
session.history.push({
timestamp: new Date(),
message: message,
role: 'user'
});
// 保持上下文窗口
if (session.history.length > this.contextWindow) {
session.history.shift();
}
// 处理消息
const response = await this.generateResponse(session, message);
// 更新会话状态
session.lastActive = new Date();
session.history.push({
timestamp: new Date(),
message: response.text,
role: 'assistant'
});
return response;
}
getSession(userId) {
if (!this.sessions.has(userId)) {
this.sessions.set(userId, {
id: userId,
history: [],
context: {},
lastActive: new Date()
});
}
return this.sessions.get(userId);
}
}
📊 数据模型设计

session_id VARCHAR(50),
message TEXT NOT NULL,
response TEXT,
intent VARCHAR(50),
confidence DECIMAL(3,2),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
processing_time INTEGER, -- 处理耗时(ms)
feedback_score INTEGER, -- 用户反馈(1-5分)
INDEX idx_user_time (user_id, created_at),
INDEX idx_intent (intent)
);
知识库条目表
CREATE TABLE knowledge_entries (
id INTEGER PRIMARY KEY AUTOINCREMENT,
question TEXT NOT NULL,
answer TEXT NOT NULL,
category VARCHAR(50),
tags TEXT, -- JSON格式存储标签
source VARCHAR(100), -- 来源标识
priority INTEGER DEFAULT 0, -- 优先级
usage_count INTEGER DEFAULT 0, -- 使用次数
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
INDEX idx_category (category),
INDEX idx_tags (tags)
);
