问题标签 [alchemyapi]

我正在使用 Bluemix 环境和 Node-RED 流编辑器。在尝试为 AlchemyAPI 服务使用内置 Node-RED 的特征提取节点时，我发现它很难使用。

我尝试将它连接到 HTTP 请求节点、HTTP 响应节点等，但没有结果。也许我没有正确完成连接过程？

我需要这段代码来使用特定公司的 AlchemyAPI 新闻数据获取 Twitter 新闻和新闻，并为 IBM HDFS 提供情绪评分并存储在其中。

这是代码：

我有一个文本文件，其中用户 ID 和推文文本由“-->”分隔。我想将这些加载到字典中，然后迭代这些值，使用 AlchemyAPI 计算每条推文的情绪。我的输入数据与此类似（真实文件有数百万条记录）：

我的代码是：

我收到错误消息：

我不明白我做错了什么。有人可以帮忙吗？

我正在尝试编写一个纯函数以将 Alchemy API 与 watson-developer-cloud npm 包一起使用，但我无法弄清楚如何同步执行其调用。是否有替代方法或包可以让我同步接收其结果？在 I/O 发生时阻塞是绝对没问题的。

有谁知道我如何查询 Alchemy News API 以检索过去 24 小时内所有文章的样本，直到指定的计数？昨天，我使用下面的查询来获取 1,000 篇提取概念的文章，并且运行良好。但是，由于某种原因，今天的相同查询只给出了大约 24 个结果。

谢谢。

我正在尝试查询 AlchemyData 新闻以查找由不同类型的多个实体（例如，文章正文中的公司“IBM”和操作系统“Linux”）缩小的文章，但运气不佳。

我可以在标题中找到或找出多个实体文本的示例：

q.enriched.url.title=A[IBM^Linux]

对于标题中的单个文本和类型：

q.enriched.url.enrichedTitle.relations.relation=|object.entities.entity.text=IBM,object.entities.entity.type=Company|

但这种组合让我望而却步。

我也不确定在搜索文章正文时使用哪个字段名称，而不仅仅是标题。

I've looked in the watson-developer-cloud package and its namesake namespace on GitHub. Will I need to go directly to the REST API in my app?

• 我按照这里的说明在 symfony2 中安装 alchemyapi_php 包： https ://packagist.org/packages/alchemyai/alchemyapi_php
• 我收到此错误：
  [InvalidArgumentException] 无法在任何版本中找到包 alchemyai/alchemyapi_php 以获得最低稳定性（稳定）。检查包装拼写或您的最低稳定性
• 可能有什么问题？

我正在尝试使用 JSONP 帖子通过 JavaScript 客户端应用程序测试调用 Alchemy News API。

我的 JSON 结果如下所示：

我可以使用以下代码成功调用 API（取自How do I get the JSON from an API request into my page's javascript?）

我真正苦苦挣扎的是访问返回对象中的数据。我可以毫无问题地读取诸如状态
之类的 顶级值，但我似乎可以从架构中更深层次的信息中加载任何值。

谁能发布我如何访问标题字段中的数据？

提前谢谢了。

是否有适用于 iOS 原生开发人员的使用 Swift/Objective-C 的 AlchemyAPI 软件开发工具包 (sdk)？

我一直在对 AlchemyAPI 中的 News API 进行一些研究。我发现有时即使我在查询中包含“start=now-1d&end=now”，它也会返回几年前的新闻。谁能告诉我如何解决这个问题？非常感谢。
