3. 知識管理系統

import chromadb
from chromadb.utils import embedding_functions
import markdown
from bs4 import BeautifulSoupclass KnowledgeManager:def __init__(self, db_path="knowledge_db"):self.client = chromadb.PersistentClient(path=db_path)self.ef = embedding_functions.OpenAIEmbeddingFunction(api_key=os.getenv("OPENAI_API_KEY"),model_name="text-embedding-3-small")self.collection = self.client.get_or_create_collection(name="research_knowledge",embedding_function=self.ef)def add_knowledge(self, document, metadata=None):"""添加知識文檔"""# 提取純文本html = markdown.markdown(document)soup = BeautifulSoup(html, "html.parser")text = soup.get_text()# 生成嵌入向量并存儲self.collection.add(documents=[text],metadatas=[metadata] if metadata else [{}],ids=[f"id{self.collection.count() + 1}"])return Truedef retrieve_knowledge(self, query, top_k=5):"""知識檢索"""results = self.collection.query(query_texts=[query],n_results=top_k)return [{"document": doc,"metadata": meta,"distance": dist} for doc, meta, dist in zip(results["documents"][0],results["metadatas"][0],results["distances"][0])]def generate_report(self, topic, length=1000):"""生成知識報告"""# 檢索相關知識context = self.retrieve_knowledge(topic, top_k=3)context_text = "\n\n".join([f"來源：{c['metadata'].get('source','')}\n內容：{c['document'][:500]}" for c in context])prompt = f"""基于以下背景知識，撰寫關于'{topic}'的綜合性報告：

四、關鍵技術實現

1. 動態工作流引擎

2. 知識圖譜構建

from py2neo import Graphclass KnowledgeGraph:def __init__(self, uri, user, password):self.graph = Graph(uri, auth=(user, password))def build_from_text(self, text):"""從文本構建知識圖譜"""# 實體關系提取prompt = f"""從以下研究文本中提取實體及其關系：

五、企業級部署方案

1. 云原生架構

2. Docker部署腳本

# docker-compose.yaml
version: '3.8'
services:api-gateway:image: nginx:alpineports:- "80:80"volumes:- ./nginx.conf:/etc/nginx/nginx.confworkflow-engine:build: ./workflowenvironment:OPENAI_API_KEY: ${OPENAI_API_KEY}depends_on:- redis- neo4jknowledge-service:build: ./knowledgeenvironment:CHROMA_DB_PATH: /datavolumes:- ./knowledge_data:/dataredis:image: redis:alpineneo4j:image: neo4j:5.12environment:NEO4J_AUTH: neo4j/passwordvolumes:- ./neo4j_data:/data# 啟動命令
docker-compose up -d

六、應用案例：藥物研發項目

# 初始化工作流
workflow = ResearchWorkflow()# 啟動項目
project_id, plan = workflow.start_project("阿爾茨海默癥新型藥物靶點")print("研究計劃：")
print(plan)# 生成并驗證假設
hypothesis = "抑制Tau蛋白過度磷酸化可改善阿爾茨海默癥癥狀"
interpretation = workflow.run_experiment(project_id, hypothesis)print("實驗結果分析：")
print(interpretation)# 生成最終報告
report = workflow.generate_final_report(project_id)with open("final_report.md", "w") as f:f.write(report)

七、性能優化策略

1. 提示工程優化

def optimize_prompt(prompt):"""優化提示工程"""optimization_prompt = f"""
請優化以下GPT提示以提高響應質量和效率：
原始提示：{prompt}優化要求：
1. 明確輸出格式
2. 添加角色設定
3. 增加約束條件
4. 長度減少30%但保留核心信息優化后提示："""response = client.chat.completions.create(model="gpt-4-turbo",messages=[{"role": "user", "content": optimization_prompt}],max_tokens=500)return response.choices[0].message.content.strip()

2. 緩存機制

from functools import lru_cache
import hashlib@lru_cache(maxsize=1000)
def cached_gpt4(prompt, max_tokens=500):"""帶緩存的GPT-4調用"""prompt_hash = hashlib.md5(prompt.encode()).hexdigest()cache_file = f"cache/{prompt_hash}.json"if os.path.exists(cache_file):with open(cache_file, "r") as f:return json.load(f)response = client.chat.completions.create(model="gpt-4-turbo",messages=[{"role": "user", "content": prompt}],max_tokens=max_tokens)result = response.choices[0].message.content.strip()with open(cache_file, "w") as f:json.dump(result, f)return result
