炼金术新闻摘录

Question

我们正在格式化并向用户呈现Alchemy Data News查询结果。我想我看到其他演示这样做（例如 Watson News Explorer），它们显示了每篇文章的小摘录。我没有看到Alchemy Data News API返回的任何摘录。我们的查询中是否缺少某些内容？我们如何为用户显示新闻报道的摘录？

Answer 1

您可以使用

return=enriched.url.text 检索文本示例

在此处查看完整的参数列表

例如

https://gateway-a.watsonplatform.net/calls/data/GetNews?apikey=****
  &outputMode=json&start=now-1d&end=now&count=100
  &q.enriched.url.enrichedTitle.relations.relation
  =|action.verb.text=acquire,object.entities.entity.type=Company|
  &return=enriched.url.text

会回来
