Llama 包 - 简历筛选器 📄¶

此示例展示了如何使用简历筛选器 Llama 包。您可以在 https://llamahub.ai 上找到所有包

简历筛选器旨在根据一组标准分析候选人的简历，并决定候选人是否适合该职位。

在此示例中，我们将评估一份示例简历（例如，Jerry 的旧简历）。

设置数据¶

我们将加载一些关于 OpenAI、Sam、Mira 和 Emmett 的维基百科样本数据。为什么？没有特别的原因 :)

In [ ]

from llama_index.readers.wikipedia import WikipediaReader

loader = WikipediaReader()
documents = loader.load_data(
    pages=["OpenAI", "Sam Altman", "Mira Murati", "Emmett Shear"],
    auto_suggest=False,
)

from llama_index.readers.wikipedia import WikipediaReader loader = WikipediaReader() documents = loader.load_data( pages=["OpenAI", "Sam Altman", "Mira Murati", "Emmett Shear"], auto_suggest=False, )

In [ ]

# do sentence splitting on the first piece of text
from llama_index.core.node_parser import SentenceSplitter

# do sentence splitting on the first piece of text from llama_index.core.node_parser import SentenceSplitter

In [ ]

sentence_splitter = SentenceSplitter(chunk_size=1024)

sentence_splitter = SentenceSplitter(chunk_size=1024)

我们获取每篇文章的第一个块。

In [ ]

# get the first 1024 tokens for each entity
openai_node = sentence_splitter.get_nodes_from_documents([documents[0]])[0]
sama_node = sentence_splitter.get_nodes_from_documents([documents[1]])[0]
mira_node = sentence_splitter.get_nodes_from_documents([documents[2]])[0]
emmett_node = sentence_splitter.get_nodes_from_documents([documents[3]])[0]

# get the first 1024 tokens for each entity openai_node = sentence_splitter.get_nodes_from_documents([documents[0]])[0] sama_node = sentence_splitter.get_nodes_from_documents([documents[1]])[0] mira_node = sentence_splitter.get_nodes_from_documents([documents[2]])[0] emmett_node = sentence_splitter.get_nodes_from_documents([documents[3]])[0]

我们还将下载 Jerry 在 2019 年的简历。

从 LlamaHub 下载简历筛选器包¶

这里我们从 LlamaHub 下载简历筛选器包类。

我们将用它来实现两个用例

• 候选人是否适合前端 / 全栈工程师职位。
