AskNews

AskNews 通过单一的自然语言查询为任何LLM注入最新的全球新闻（或历史新闻）。具体来说，AskNews每天丰富超过30万篇文章，通过翻译、摘要、提取实体并将它们索引到热向量和冷向量数据库中。AskNews将这些向量数据库放在一个低延迟的端点上供您使用。当您查询AskNews时，您会收到一个经过优化的提示字符串，其中包含所有最相关的丰富信息（例如实体、分类、翻译、摘要）。这意味着您无需管理自己的新闻RAG，也无需担心如何以简洁的方式正确传达新闻信息给您的LLM。

AskNews还致力于透明度，这就是为什么我们的报道受到监控，并在数百个国家、13种语言和5万个来源之间进行了多样化。如果您想追踪我们的来源覆盖范围，您可以访问我们的透明度仪表板。

设置​

集成位于langchain-community包中。我们还需要安装asknews包本身。

pip install -U langchain-community asknews

我们还需要设置我们的AskNews API凭据，这可以在AskNews控制台上获得。

import getpass
import os
os.environ["ASKNEWS_CLIENT_ID"] = getpass.getpass()
os.environ["ASKNEWS_CLIENT_SECRET"] = getpass.getpass()

用法​

这里我们展示如何单独使用这个工具。

from langchain_community.tools.asknews import AskNewsSearch
tool = AskNewsSearch(max_results=2)
tool.invoke({"query": "Effect of fed policy on tech sector"})
"\n<doc>\n[1]:\ntitle: Market Awaits Comments From Key Fed Official\nsummary: The market is awaiting comments from Fed Governor Christopher Waller, but it's not expected to move markets significantly. The recent Consumer Price Index (CPI) report showed slimming inflation figures, leading to a conclusion that inflation is being curbed. This has led to a 'soft landing' narrative, causing bullish sentiment in the stock market, with the Dow, S&P 500, Nasdaq, and Russell 2000 indices near all-time highs. NVIDIA is set to report earnings next week, and despite its 95% year-to-date growth, it remains a Zacks Rank #1 (Strong Buy) stock. The article also mentions upcoming economic data releases, including New and Existing Home Sales, S&P flash PMI Services and Manufacturing, Durable Goods, and Weekly Jobless Claims.\nsource: Yahoo\npublished: May 17 2024 14:53\nOrganization: Nasdaq, Fed, NVIDIA, Zacks\nPerson: Christopher Waller\nEvent: Weekly Jobless Claims\nclassification: Business\nsentiment: 0\n</doc>\n\n<doc>\n[2]:\ntitle: US futures flat as Fed comments cool rate cut optimism\nsummary: US stock index futures remained flat on Thursday evening, following a weak finish on Wall Street, as Federal Reserve officials warned that bets on interest rate cuts were potentially premature. The Fed officials, including Atlanta Fed President Raphael Bostic, New York Fed President John Williams, and Cleveland Fed President Loretta Mester, stated that the central bank still needed more confidence to cut interest rates, and that the timing of the move remained uncertain. As a result, investors slightly trimmed their expectations for a September rate cut, and the S&P 500 and Nasdaq 100 indexes fell 0.2% and 0.3%, respectively. Meanwhile, Reddit surged 11% after announcing a partnership with OpenAI, while Take-Two Interactive and DXC Technology fell after issuing disappointing earnings guidance.\nsource: Yahoo\npublished: May 16 2024 20:08\nLocation: US, Wall Street\nDate: September, Thursday\nOrganization: Atlanta Fed, Cleveland Fed, New York Fed, Fed, Reddit, Take-Two Interactive, DXC Technology, OpenAI, Federal Reserve\nTitle: President\nPerson: Loretta Mester, Raphael Bostic, John Williams\nclassification: Business\nsentiment: 0\n</doc>\n"

我们在这里展示如何将其作为代理的一部分使用。我们使用OpenAI Functions代理，因此我们需要为其设置和安装所需的依赖项。我们还将使用LangSmith Hub来提取提示，因此我们需要安装它。

pip install -U langchain-openai langchainhub
import getpass
import os
os.environ["OPENAI_API_KEY"] = getpass.getpass()
from langchain import hub
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain_community.tools.asknews import AskNewsSearch
from langchain_openai import ChatOpenAI
prompt = hub.pull("hwchase17/openai-functions-agent")
llm = ChatOpenAI(temperature=0)
asknews_tool = AskNewsSearch()
tools = [asknews_tool]
agent = create_openai_functions_agent(llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools)
agent_executor.invoke({"input": "How is the tech sector being affected by fed policy?"})
