back to article Taking a first bite out of Wolfram Alpha

Is it the newest rival to Google, likely to knock Google off the top spot? No it isn’t. Does it provides a single answer to complex questions – unlike traditional search engines? Nope. Could it possibly be "a natural search engine"? Not quite. The newest game in town, if Twitter is anything to go by, is the Wolfram Alpha …

    more competition

    This can only mean good things for Search Engine users. Competition will increase and just like what is happening with other industries, smaller players will emerge with great solutions. Reminds me of a recent Search Engine (SEOENG) that also appealed to a narrow group of people, but nonetheless solved a problem not yet addressed by the major Search Engines.

    It's not a search engine

    It's an expert system. Still an impressive feat, but calling it a search engine is just an attempt to jam it into the current fad about what computers should be spending their time on. It's not a way to interact with the internet at all.

    It works better than I thought it would when I read the blurb a while back.

    That said, there are clearly some 'gaps' in data that it should know about. For example, it knows all about Tropical Storm 'Fay' in 2002 but knows nothing of the larger storm of the same name in 2008.

    I'm still quite impressed though.

    It also cannot...

    ...tell me how many stomachs a badger or cow has.

    Nor is it able to give a full answer to "how many kilobytes per megabyte", because it ignores what's been the usual since the 60's and only gives the SI answer. It doesn't even mention that until recently, a meg was 1024kb - even though almost every single dictionary (a source that should be aggregated) defines a megabyte using the 1960's method, not the SI method.

    So it's ok... as long as you check it's answers through Google. So... might as well just Google it?

Not sure if the "doesn't know what you mean" thing is actually a doesn't know, and is actually a "given to much time to looking, and giving up" answer...possibly due to everyone clobbering it for answers at the moment.

    The key sentence in the article is "For if any one thing is certain, the non-specialist press just love to tear apart new technologies the moment they fail to live up to claims they never made in the first place."

    As far as I am aware Wolfram have never said that this the current release is the final version of the search engine. It's a great pity that Alpha will be commented on in the popular press, by people with significantly lower intellect than those working at Wolfram.

    I for one hope that Wolfram is successful. I seem to remember that Mathematica was treated with some suspicion when it was released because many people simply did not understand it.

    Solution looking for a problem

    It's obviously intended to be an engine for extracting facts from the internet. However, I see it mostly as a filter for restricting your view of the internet to just those facts that happen to fit its model.

    As such, it's basically like a very restricted form of Wikipedia. By using it, you're accepting someone else's pre-digested view of what's going on in the world. Obviously, even Google must have some bias about which links it shows in response to keywords, but at least you can sample a few links to judge the range of what's available (or even try another search engine). With Wolfram|Alpha, you're basically trusting big brother to tell you the truth.

    Not really a problem you might think? Then what does it have to say about the reality of climate change, for example? Can it plot a graph of future global temperatures (or even historical temperatures) that everyone would be happy with? Is it able to decide when something ceases to be a fact and becomes opinion? I'd say even humans aren't very good at that - and that causes a whole load of trouble.

    And what happens when it deduces the wrong answer to some very popular query? Does it become an urban myth machine? Will its gullible users just repeat the garbage it produces until everyone starts to believe it?

    Honestly, I can't see myself using this for getting the answer to anything that matters. I'm always going to have to check the result with something else, like Google. So why even bother?

    Speed of Swallow

    It may not know the speed of a general unladen swallow (try "what's the speed of an unladen swallow") but it does at least give a reason why. Get more specific and click on the link for a European swallow, and it will give you the answer - even noting Monty Python as the question source.

    For most people, Wolfram Alpha is going to be of limited use. Sure it can tell you the weather with pretty graphs and a few other stats, but really it's best for a set of technical questions that combine interpretation, calculation and display of data. Hopefully though it will keep improving as I find it better than Google for certain queries.

    Is this really what we need?

    Beside the fact that it does not work very well (yet?), one wonders whether it is really a good idea to try get actual answers from the internet.

    Google's searches return (mostly) relevant information but still require the reader to actually apply some reasoning and interpretation to get to the real answer. Considering all the rubbish out there this is probably a far better way to handle information from the internet.

    WA might technically work, but if it runs in Mathematica (even compiled) then it will just never be able to scale like Google does.

    I tried WA from New Zealand South Island with two questions:

    Question: "How many sheep in New Zealand?"

    WA answer: Can't understand input.

    Google: NZ population statistics page giving a reasonable number.

    Question: "Where is Wellington?"

    WA answer: Map with a star at the bottom of North Island. Reasonable answer.

    Google answer: Google map of Wellington + wikipedia link + other associated info.

    Correct answer: Who cares.

    Limited datasets

    I was interested in comparing the performance of some laptops, so I entered the CPU labels, but WolframAlpha didn't recognize them. It seems like the sort of data that might be useful in this kind of "engine".

    I also asked it about "population density in EU countries", but it apparently couldn't parse the phrase "EU countries", giving be an average population density for the whole EU (so it recognized that term) , and for the whole world (all countries).

    Just asking for "population density in EU" worked, and it's interesting to compare it to "population density in Western Europe", so it's clearly a powerful tool, but it's not going to pass any Turing tests!

    Re: @ Keith T

    @Greg Fleming:

    The difference is that Google is an index of web pages; it does not provide knowledge nor gauges the accuracy of it's results--and as a matter of fact, contains no content at all, just links to other resources. You ask it a question, and it will retrieve a list of resources that it thinks are relevant, based on various factors which may even include popularity. However, it only knows what's on the Internet, which as has been pointed out before, even by El Reg's Mr. Orlowski, the Internet is far from representative of the collection of human culture and knowledge.

    Wolfram|Alpha is a collection of facts compiled from various resources (available to you for reference), most definitely *not* web pages. It is not an index of, nor it represents a "new way to interact with the Internet"; it is a searchable database with a computational engine and expert system that allows you to combine and correlate any of its myriad data points.

    As the article said, the the data sets are currently few, so it is understandable that it cannot respond to every query. However, it should be understood that even this is no small feat, as the data sets contained are vast themselves. Don't think works of Shakespear, think the English language; don't think recent hurricane patterns, think historical weather data for the last century. Surely you can see the potential of such a system if its database continues to grow.

    In more popular term, I would say that Google is closer to The Hitchhiker's Guide to the Galaxy, while Wolfram|Alpha represents The Encyclopaedia Galactica.

    I suggest you and others watch the demo presentation, where Mr. Wolfram explains and shows the capabilities of the system.

    Not all bad

    It was very good at telling me tomorrow's weather in Brno. Or rather, collating the weather forecast for the rest of the week in Brno. I'll tell you tomorrow whether it was accurate...

    In case anyone cares,...

    ... it's been right about the weather in Brno so far. Mrs S tells me it's had the weather spot on in our obscure little home town as well. Quite clever, actually.

    Charge on an electron is rounded

    Ask Wolfram Alpha what is the charge on an electron and you will get an answer of 1.6021765x10^-19 C.

    But the best avaiable data is the CODATA 2006, which is what is reffered to by both NIST in the USA and NPL in the UK.

    Wolfram Alpha have the value from CODATA 2006, but it has been rounded to 8 significant digits. The internationally agreed value is 1.602176487x10-19 C, not the value Wolfram Alpha gives.

    So far from being a 'primary source' as Wolfram Research claim, it is taking primary data and rounding it. Wikipedia has the right value.

    I'm a user of Mathematica and find that program impressive, although the free open-source Sage looks as though it will be a thorne in the side of Wolfram Reserach. I was impressed the day I first see Mathematica - more than 20 years ago. But I can't see much of use in Wolfram Alpha. It appears to be a poor man's Mathematica. For most things web relatved, google is far more useful.

    I'm sure Wolfram Alpha will improve over time, but I can't ever see it being too succesful myself.
