Say whaaat? This week on Google Cloud Platform

In case you hadn’t heard, we here at Google Cloud Platform
released the Cloud Natural Language API
this week, and an open beta of the
Speech API
.
Both the Natural Language and Speech APIs are just the latest examples in the
Cloud Machine Learning
technologies that we’ve made available to the public, following on the heels of the
Vision API
and
Translate API
. But what exactly do these latest APIs allow you to do?
Natural Language is all about parsing written text — you know, the kind that you’re looking at right now. By way of introduction, check out Google Developer Advocate
Sara Robinson’s
post on how she used the Natural Language API
to analyze stories
in The New York Times, while introducing us to the NL concepts of “sentiment” and “entities.”
Google Developer Advocate
Guillaume Laforge dives deeper into sentiments
by color coding tweets as strong positive, strongly negative — or somewhere in between — according to the polarity and magnitude unearthed by Natural Language. Turns out that
@googlecloud
tweets are all over the map, sentiment-wise, judging by this many-colored chart.
Positive tweets are green, negative tweets are red and neutral tweets are yellow
Others may choose to sample much less colorful text streams, such as
Theresa May’s inaugural speech as British Prime Minister
. In a blog,
Javier Ramirez
, a Google expert at Teowaki,
uses the Speech API
to convert the audio to text, then feeds it to Natural Language to analyze its entities and sentiments. “I never suspected Brexit could be this fun,” he writes.
But how reliable are these latest machine learning offerings? Make no mistake, it’s early days, and natural language processing is an imperfect science. Over on Hacker News, some people reported mixed results with Natural Language. Check out
the conversation
with Google Natural Language Product Manager Dave Orr, who explains why a sentence that is so easy for a human “wetware” brain to understand can still trip up a computer. “It's the curse of [natural language processing], really,” he says. “All the easy things are hard. (And the hard things are nigh impossible.)”
We hope you’ll be the judge. Scroll down to the bottom of the
Cloud Natural Language API
page, and enter a snippet of text and try the API.
