四、关键技术实现

1. 动态工作流引擎

2. 知识图谱构建

from py2neo import Graphclass KnowledgeGraph:def __init__(self, uri, user, password):self.graph = Graph(uri, auth=(user, password))def build_from_text(self, text):"""从文本构建知识图谱"""# 实体关系提取prompt = f"""从以下研究文本中提取实体及其关系：

五、企业级部署方案

1. 云原生架构

2. Docker部署脚本

# 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# 启动命令
docker-compose up -d

六、应用案例：药物研发项目

# 初始化工作流
workflow = ResearchWorkflow()# 启动项目
project_id, plan = workflow.start_project("阿尔茨海默症新型药物靶点")print("研究计划：")
print(plan)# 生成并验证假设
hypothesis = "抑制Tau蛋白过度磷酸化可改善阿尔茨海默症症状"
interpretation = workflow.run_experiment(project_id, hypothesis)print("实验结果分析：")
print(interpretation)# 生成最终报告
report = workflow.generate_final_report(project_id)with open("final_report.md", "w") as f:f.write(report)

七、性能优化策略

1. 提示工程优化

def optimize_prompt(prompt):"""优化提示工程"""optimization_prompt = f"""
请优化以下GPT提示以提高响应质量和效率：
原始提示：{prompt}优化要求：
1. 明确输出格式
2. 添加角色设定
3. 增加约束条件
4. 长度减少30%但保留核心信息优化后提示："""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. 缓存机制

from functools import lru_cache
import hashlib@lru_cache(maxsize=1000)
def cached_gpt4(prompt, max_tokens=500):"""带缓存的GPT-4调用"""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
