在 Alchemy api 演示中没有选择正确的作者字段

Not picking up the correct author field in alchemy api demo

我正在试用在线演示:http://www.alchemyapi.com/products/demo/alchemylanguage

我粘贴了你的一篇博客文章:http://www.programmableweb.com/news/alchemyapi-updates-api-brings-deep-learning-to-masses/2013/07/25

对于 Alchemyapi 返回的作者字段,我得到 'Google+' 而在博客文章中它说作者是 'Amy Castor'

发生这种情况的原因是什么?

顺便说一句。我最近 post 访问了 ibm dwanswers,但发现他们正在转向 Whosebug,因此交叉 post

来自Author Extraction documentation:

The author information can be embedded into a news article or a blog post in a multitude of different ways, including in the page meta data, using REL links, just plain text, and others. Since there's no standard way to express the author via HTML tags (i.e. like the tags), reliably extracting the author is a complex task. AlchemyAPI uses over a dozen techniques in parallel to attempt to find the author, and then cross references the results to determine the most likely candidate for the author. AlchemyAPI makes the difficult task of author extraction easy to integrate into your application.

它认为作者在该特定文章上是 Google+ 的原因是因为它出现在 REL link.

文章底部写着:

About the author: Amy Castor Follow me on Google+

那 Google+ 字 link 到 https://plus.google.com/108856065353244179079?rel=author

算法正在接受这个 ?rel=author 参数,因此认为 Google+ 是作者。

在很多情况下这是正确的,但这是错误的情况之一 - 这就是认知计算的本质。
