Finding Powerset Factz
Obviously, I don't need any more Powerset t-shirts, but I thought I'd show off some of the fun queries that I found and talk a little bit about the process I went through to find good queries.
Some knowledge about how Factz show up are helpful in finding them. First, Factz are currently very simple "triples" of subject:verb:object. So, if you start asking questions with prepositional phrases (Who starred in Six Degrees of Separation?), a when (when did Mount St. Helens erupt?), or any other construction, you will get search results, but no Factz results. Also, Factz most often return about popular subjects, because they are written about in many places in Wikipedia, not just their own Wikipedia article.
With that out of the way, let's look at an example. I like chess, so a good starting point is a chess query: bobby fischer.
The Factz are grouped by relation and, even though by default Powerset only shows three results, there over 100 relations featuring Bobby Fischer as the subject. Just click "more" to see all of the relations.
The third relation is about Bobby Fischer defeating, which in turn suggests a simple question: who did bobby fischer defeat? (yes, I know that it should be "whom")
Though this isn't a complete list, it's a list of all of the sentences in Wikipedia that have Bobby Fischer as the subject for the verb defeat. So, one way to get a good Factz query is to type in the name of a topic, look at the top relations, and then turn that relationship into a question.
However, sometimes Factz can also be used to get a list of subjects. In this case, you can flip the question around to see who defeated Bobby Fischer.
Another good general principle about great Factz queries is thinking about a question that will generate a long list. I watched The Incredibles for the first time last night. This got me thinking about the query, who saves the world?
If you click "more" you'll see that this is a really long list with some that are expected (lots of heros saved the world), logical (Christ), funny (Godzilla), and wrong (Nova Scotia). Note that Powerset always shows the sentence from which the Factz were derived, allowing you to double check whether the assertion is true.
Sometimes Factz can reveal things that are either not true or "almost" true. For the query, who invaded Mexico, I was curious about Japan, since that bit of history evaded my memory. Sure enough, it wasn't my memory that was deficient, but the sentence was: "On June 3, 1942, Patton believed the Japanese were on a course to invade Mexico." Powermouse ignores these types of modalities and negations, even though Powerset indexes them properly. We do this because we err on the side of giving users too much information, rather than too little.
Hopefully this will help you find some good Factz for Powerset's t-shirt contest. If you have any questions, you can comment on my blog or drop us a line at feedback@powerset.com
