抓取 Wikipedia

从 Wikipedia 提取文章与信息框，构建知识图谱

了解如何高效抓取 Wikipedia，用于研究、知识抽取与构建 AI 应用。

​

安装与配置

npm install @mendable/firecrawl-js zod

​

使用场景

• 研究流程自动化与事实核查
• 构建知识图谱
• 多语言内容提取
• 教育内容聚合
• 实体信息抽取

​

使用 JSON 模式进行抓取

使用 Zod 模式从 Wikipedia 条目中提取结构化数据。

import FirecrawlApp from '@mendable/firecrawl-js';
import { z } from 'zod';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/JavaScript', {
    formats: [{
        type: 'json',
        schema: z.object({
            name: z.string(),
            creator: z.string(),
            firstAppeared: z.string(),
            typingDiscipline: z.string(),
            website: z.string()
        })
    }]
});

console.log(result.json);

​

搜索

在维基百科上搜索文章。

import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const searchResult = await firecrawl.search('quantum computing site:en.wikipedia.org', {
    limit: 10,
    sources: [{ type: 'web' }], // { type: 'news' }, { type: 'images' }
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(searchResult);

​

抓取

抓取单个维基百科页面。

import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/Artificial_intelligence', {
    formats: ['markdown'], // 例如 html、links 等
    onlyMainContent: true
});

console.log(result);

​

Map

在 Wikipedia 门户或分类下发现所有可用的 URL。注意：Map 只返回 URL，不包含页面内容。

import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const mapResult = await firecrawl.map('https://en.wikipedia.org/wiki/Portal:Computer_science');

console.log(mapResult.links);
// 返回 URL 数组,不包含内容

​

Crawl

从维基百科的文档或分类中爬取多个页面。

import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const crawlResult = await firecrawl.crawl('https://en.wikipedia.org/wiki/Portal:Artificial_intelligence', {
    limit: 10,
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(crawlResult.data);

​

批量抓取

一次性抓取多个 Wikipedia 链接。

import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

// 等待完成
const job = await firecrawl.batchScrape([
    'https://en.wikipedia.org/wiki/Machine_learning',
    'https://en.wikipedia.org/wiki/Artificial_intelligence',
    'https://en.wikipedia.org/wiki/Deep_learning'],
    {
        options: {
            formats: ['markdown']
        },
        pollInterval: 2,
        timeout: 120
    }
);


console.log(job.status, job.completed, job.total);

console.log(job);
