Google Now beats Cortana and Siri in knowledge base competition

Google Now beats Cortana and Siri in knowledge base competition
We've all seen the videos and articles that compare Google Now, Siri, and Cortana, but most are relatively limited in scope, because of time/article length constraints. That is not what we're seeing from Stone Mountain Consulting, which compared the three products by asking the same 3000+ questions to each. Of course, the testing was specifically targeting the knowledge base of each, so it probably shouldn't be a surprise that Google Now won this fight.

Part of the study looked at how the query answers were presented to the user. In this case, Google Now showed a separate card with the query answer along with the other search results 58% of the time, while Siri included that knowledge base data 29% of the time, and Cortana just 20% of the time. However, that's really just a matter of formatting and contextual information, a much more important factor is how often your question is answered completely, and in that case Google Now blew away the competition. 

Google Now returned the complete answer a whopping 88% of the time, while Siri was at 53%, and Cortana at 40%. It should be noted how that was judged - if the question was "How old is the Great Wall of China?" an answer was only deemed complete if the knowledge card data returned the answer of ~2220 years old. If the card said that the Great Wall was built in 206 BC, that wouldn't count as complete, nor would it count if the search results below contained the answer. Given how much more often Google Now has knowledge cards included, it was already poised to win, but having an 88% success rate for complete answers under those strict guidelines is still very impressive. 

We considered giving Cortana a bit of leeway for being the newcomer, but while Cortana is new, the knowledge base it draws on (Bing) has been around since mid-2009. Given Bing's relative age, it's actually a bit sad to see Apple ahead of Cortana, especially since Apple doesn't own a search engine. 

Of course, as we noted at the start, this was a competition strictly in terms of getting answers to knowledge base questions, and did not judge differences between virtual assistant functions of each. When it comes to setting reminders, changing phone settings, managing your calendar, sending messages and more, you may have a different take on the strengths of each system.

I love using "go go gadget Starbucks" on my Android Wear watch. To pay for my coffee.

I always thought Google Now was pretty awesome even though I was testing it on iOS. I think Google Now needs a little of a personality to be real near-perfect but as for the actual job it was given... it's pretty good.

I have to disagree with you, the dry verbal response you get when it responds with a funny answer to a dumb question is pretty freakin funny. Cortana is an awesome piece of software, but right not it's like the blond of the three personal assistants, full of personality but lacking in capability. Still though, Microsoft is working hard to develop Cortana so I'm excited to see where it goes in the years to come.

Yes , cortana is catching up very quickly. Heard that she'll be integrated in Search in W10 :)

Haha, I guess it's funny for a while but you know, looking onwards, to truly best this design would mean to give your personal assistant a personality of sorts. On a similar topic: Yar, Cortana is looking awesome and is catching up, FAST!

No surprise :D But I have to admit that Cortana is doing well...Remember that it is in beta state :D

Given the test, not surprised with the results. However these are all virtual assistants and mot Snapple fact spitting features. But hey, Cortland is still in beta... some ways to go for all three platforms with regards to their virtual assistants.

That last paragraph is important for this article.

I dont see how...when the article is about a knowledge tests between the 3, not functionality, features, etc That last paragraph is important for each person to decide whats best for them, has nothing to do with the article.

For a Halo fan's overview, Cortana together with Master Chief they concquered the universe. And now she's on my WP which might think it's awesome. She reads my texts, reminders, ask me to reply, little bit of everything. She might not be as great as Google's but she is perfect for Windows Phone. Sleek and witty. The greatest thing? She have a face, not just any random circle.

As far a setting reminders, and getting things on my calendar Cortana has been great. So far, she has looked up everything I asked and got me to the right places. Still, I am not about to have a heart attack and die from the shock of the surprise Google Now came in first though. This is the kind of function that plays to Google's strengths- information. I think it is a legit win that will likely hold up for a while. I just think all three are strong services, and improving quickly. No reason to jump from WP or Apple just for Google now. But another strength for Androids user base to enjoy.

Google Now should win competitions like this, since data is Google's core competency. Apple is a hardware company that sells an integrated product. They don't need your data to survive, whereas Google is an advertising company that would go bankrupt if the data stopped flowing. Silly comparison.

Just because google is a search doesn't make this comparison silly!!! If so then apple should never have made a siri....or atleast they should use google's data.... Just because your fav company lost it became useless to you...

It's not that, at all. I have conceded that point every time I talk about the two. Google Now is stronger on the data side, and Siri has more functionality. Google is data driven, so it is just inevitable they are stronger there. They prioritize knowing everything about their users because that is where the majority of their income is derived. Apple does not, and you canopy out of things you can't on Android, because Apple isn't an advertising company.

How does it have better functionality than google now?

Oh yea.....see what Michael thought about Bing. MS isnt an advertizing company either...but its a damn shame Siri did better than Cortana. Seeing as how Apple doesnt have a search engine. Maybe Google and Apple handle personal data better than MS, huh....
