隐喻搜索

本文档介绍如何使用隐喻搜索。

首先，您需要设置正确的 API 密钥和环境变量。在此处[注册获取早期访问权限](Sign up for early access here)来请求一个 API 密钥。

然后将您的 API 密钥输入为一个环境变量。

import os
os.environ["METAPHOR_API_KEY"] = ""

from langchain.utilities import MetaphorSearchAPIWrapper

search = MetaphorSearchAPIWrapper()

调用 API

results 函数接受一个经过优化的隐喻搜索查询和结果数量（最多500个）。它返回一个包含标题、网址、作者和创建日期的结果列表。

search.results("The best blog post about AI safety is definitely this: ", 10)

将隐喻用作工具

隐喻可以作为一个工具，用来获取其他工具（如浏览工具）无法获取的网址。

from langchain.agents.agent_toolkits import PlayWrightBrowserToolkit
from langchain.tools.playwright.utils import (
    create_async_playwright_browser,# A synchronous browser is available, though it isn't compatible with jupyter.
)

async_browser = create_async_playwright_browser()
toolkit = PlayWrightBrowserToolkit.from_browser(async_browser=async_browser)
tools = toolkit.get_tools()

tools_by_name = {tool.name: tool for tool in tools}
print(tools_by_name.keys())
navigate_tool = tools_by_name["navigate_browser"]
extract_text = tools_by_name["extract_text"]

from langchain.agents import initialize_agent, AgentType
from langchain.chat_models import ChatOpenAI
from langchain.tools import MetaphorSearchResults

llm = ChatOpenAI(model_name="gpt-4", temperature=0.7)

metaphor_tool = MetaphorSearchResults(api_wrapper=search)

agent_chain = initialize_agent([metaphor_tool, extract_text, navigate_tool], llm, agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True)

agent_chain.run("find me an interesting tweet about AI safety using Metaphor, then tell me the first sentence in the post. Do not finish until able to retrieve the first sentence.")

Entering new AgentExecutor chain...
Thought: I need to find a tweet about AI safety using Metaphor Search.
Action:
```
{
  "action": "Metaphor Search Results JSON",
  "action_input": {
    "query": "interesting tweet AI safety",
    "num_results": 1
  }
}
```
{'results': [{'url': 'https://safe.ai/', 'title': 'Center for AI Safety', 'dateCreated': '2022-01-01', 'author': None, 'score': 0.18083244562149048}]}

Observation: [{'title': 'Center for AI Safety', 'url': 'https://safe.ai/', 'author': None, 'date_created': '2022-01-01'}]
Thought:I need to navigate to the URL provided in the search results to find the tweet.

Finished chain.


'I need to navigate to the URL provided in the search results to find the tweet.'
