Wolfram Alpha vs. Google — Results Vary 255

wjousts writes "Technology Review has an article comparing various search results from Wolfram Alpha and Google. Results vary. For example, searching 'Microsoft Apple' in Alpha returns data comparing both companies stock prices, whereas Google top results are news stories mentioning both companies. However, when searching for '10 pounds kilograms,' Alpha rather unhelpfully assumes you want to multiply 10 pounds by 1 kilogram, whereas Google directs you to sites for metric conversions. Change the query to '10 pounds in kilograms' and both give you the result you'd expect (i.e. 4.536 kg)."

          That's funny, I RTFA too, and I came to a completely different conclusion. I think perhaps we have different definitions of "answers".

          The conclusion I drew is that if you're looking for technical/scientific data Alpha does a much better job. In particular, it brings together lots of relevant bits and pieces which may not exist on any single web site. Google will probably find it all for you, but you'll have to do more digging. On the other hand, if you're looking for news, commentary or opinion, Google is the much better choice.

          I more frequently find myself looking for data, so I wouldn't be surprised if my usage tends to favor Alpha. Heck, as it is 95% of my usage of Google is to search for a Wikipedia article -- and often I'm looking for that to find links to tables of data. Your goals and search patterns may be different, so your usage may favor Google.

          I suspect that Alpha is going to be a very useful tool within its domain, but I don't expect it to displace Google to any significant degree.

            Any particular reason nobody couldn't improve on google? There are lots of big shortcomings in google.

            When I don't want to buy something, but google a product for reviews etc I have to sift through piles of garbage 'price comparison sites', and sites with: "0 reviews... be the first to review it".

            Google sucks for localized/regional or country specific information searches.

            Googles image search could use significant improvements.

            When I search for answers to technical questions (programming / troubleshooting / etc), I'll find a link to a question asked on some forum, with answers. If that doesn't help, I don't need the next 7 links all to be to other sites with the EXACT SAME question and answers. (Apparently a lot of forum sites spider each other and/or usenet for their content...) I don't need to see that. I also don't much need links to forums where the question was asked six months ago, and never answered.

            And going off on a bit of a tangent... 'expertsexchange' (WFT? 'expert sex change'??) Someone should really properly spider that waste of space. Sure the information is there... but what the hell??? A question, 2 pages of 'obscured' answers, then four pages of advertising for expertsexchange to get answers... but keep scrolling, and there is the question again, now with the un-obscured answers, and 2 pages of bickering about how the stupid effing points should be awarded.

            Sure the signal is there but the S/N ratio is through the roof.

            For me, other sites have -already- supplanted google as superior ways to find certain types of information.

            Wikipedia is for example is far more useful than google as a search tool to get information and links to relevant sites for a lot of topics. There's a reason an awful lot of top google hits simply take you to wikipedia... might as well cut out the middle man.

This is skewed, and bears no relation to the individual rank (and thus merit) of the wikipedia page. I want facts, not what some guy thinks. I know where wikipedia is, if I wanted to search it, I would. I don't.

    Some might say that Mathematica, the source of my fortune, and A New Kind Of Science: A Brief History Of My Stupendous Intellect were ambitious projects. But in recent years I've been hard at work on a still more ambitious project: Wolfram Alpha.

    Fifty years ago, people assumed that computers would quickly be able to handle all kinds of question. It didnâ(TM)t work out that way. But a few years ago, I realized that I was finally in a position to do it myself. As I'd always expected I'd have to, of course.

    I had the crucial ingredients: Mathematica and A New Kind Of Science. And my truly massive intellect. With these, I had a language to compute anything and a paradigm for complexity from simple rules. And my spectacular brain, which is much more spectacular than anyone else's, as proven by me being rich as well as smart. Which is smarter: to be a professor, or to have all the professors pay you tribute? I think my net worth makes the answer clear.

    But what about all the actual knowledge that we as humans have accumulated? I realized we needed to make all data computable as knowledge. Of course, natural language is incredibly difficult for computers. So we added the secret ingredient: my jaw-droppingly spectacular brain, undoubtedly the largest on Earth.

    I'm happy to say that with a mixture of clever algorithms and heuristics, linguistic discovery and curation, and some casual Nobel-worthy theoretical breakthroughs in my spare moments, we've made it work. Itâ(TM)s going to be a website with one simple input field that gives direct access to my superlative brain, in its planet-sized glory.

    Our pre-launch testers have been at work as well, and I'm dealing with all manner of queries in spare thought cycles while I jetset around the world, wowing the pitiful minds of gorgeous international supermodels before impregnating them with my superior genetic material. Let's just have a look at the query stream: "tits" "goatse" "mary whitehouse naked" "4chan" "tubgirl" "2girls1cup" "ITS OVER 9000 LOL" "desu desu desu desu"

    • If you read his claim in a "New Kind of Physics" that cellular automata would completely change and improve physics. The volume was an exhaustive exploration of all possible rules for the basic 8-neighbor, rectangular planar automata. Some interesting, but not revolutionary results.
      • Uh, excuse me, inventing the universe!

        And I would debate that 8-neighbor cellular automata, even with fully understood rules, mean ANYTHING AT ALL, aside from a tedious exploration of a vaguely interesting rule of logic. "A new kind of science" might be right - a new kind of science that is irrelevant by all previous measures and tells you nothing useful about the physical nature of the universe.

This was in the seventies.

    The book said that expert systems were largely abandoned, however, because the software was less efficient--it asked males if they were pregnant, for

    How about a test involving actual English-language questions and not just keywords? You know, like all those old tests from school that said "please use complete sentences". There is a reason languages have things like prepositions, adjectives and other parts of speech. They actually help put your communication into context.

    Nobody knows what the hell you mean with "Cancer New York" because there is no context. How about "cancer statistics for new york" or "cancer treatment in new york"?

    Alpha rather unhelpfully assumes you want to multiply 10 pounds by 1 kilogram

    Actually, while I agree that is unhelpful, I also don't like the other assumption. Maybe I'm already growing old, but I don't mind if people actually say what they mean instead of speaking or writing in some kind of shortcut-verbs-are-too-expensive-so-I-leave-them-out abbreviated style and leave it to the listener/reader to decypher whatever it could possibly be they mean.

    So if you want 10 pounds in kilograms, what exactly is the trouble with actually writing those three (counting the space) additional characters?

      Search engines have for the past decade consistently ignored grammar and thrown out those small additional words, often with a stern admonishment to the user that half their query is being ignored.

    I expect something from Wolfram like the answer Google gives to this question:

    How old is Demi Moore? []

    At the top, you'll see text that says:

    Demi Moore -- Age: 46 years (born November 11, 1962)
    According to: (some source) [more sources]

    This is the proper way of answering a question like that. I don't want just the answer. I want to know where the answer came from.

    How many french died at the Battle of Agincourt?

    I expect a number from Wolfram Alpha, as well as a cited source. There could also be, like Google, the option to choose other sources.

    Eventually, this will all boil down to me driving in my car and saying, "Computer. Tell me: At what speed did Marty McFly need to drive to travel in time?"

  • "the result you'd expect"
    I'd expect a kilo for 10 pounds.

  • The results you receive querying any database will be as good as the input data. We are doing web page searches here correct? So if I just search "microsoft apple" those two words will appear billions if not trillions of times I'm sure. Is the web engine supposed to figure out intent from that? Give me a break. The page returns that Google is giving out are probably related to user behavior after a similar search and Alpha hasn't had enough time to build up that kind of data. The second one was stupid

  • Just based on TFA, it looks like Wolfram could be a fun search tool, if you're looking for facts and trivia. Seems like most of the searches turned up facts as opposed to Google, which returns links to pages.

    At the very least it might help in the "Are You Smarter Than A Fifth Grader" part..

    Most search systems do well if you can find the "magic word", the word or phrase which nearly uniquely describes what you're looking for. When you're searching for something which is described with common words, not terms of art, search engines usually don't do well. That's where to test Alpha, which supposedly has some "understanding" of its data.

    Here's an example of something I was doing today. I'm sketching out a design for a special-purpose DC-DC converter, something I haven't done before. I'm looking at a data sheet for a transformer, and at the rules for describing a transformer to LTSpice, a circuit simulator. LTspice wants a value K, the "coupling coefficient". The data sheet for the transformer has various numbers about the transformer, but not the coupling coefficient. How do I calculate the coupling coefficient?

    It turns out that the magic words for answering this question are "leakage inductance". Once you know that, you can find the Wikipedia entry that gives the necessary conversion formulas, and calculate the coupling coefficient. Until you find the magic words, though, it's tough. If you just go looking for "coupling coefficient" in Google, you're directed to theory papers. "Leakage inductance" is the number that appears in data sheets, because it's directly measurable.

    If Alpha can answer questions like "How do I compute the coupling coefficient for a transformer given the data sheet parameters?", it will be a nice capability.

    Yet, if you put in the entire phrase "How do I compute the coupling coefficient for a transformer given the data sheet parameters?" as a query to Google, you get as a first result a paper on how to model a transformer in LTSpice given data sheet information [], which is exactly the right result to return. The answer is in that paper, and it's a good paper. Google does better at this than one might expect.

    Google for "definition of mathematical proof" (without the quotes). The #1 hit usually is a link to the site of a well-known usenet kook who thinks he's proved FLT, disproved the Rieman Hypothesis, proved P=NP, can factor numbers in constant time, and has found a contradiction in Galois theory (this is just a partial list of his accomplishments), and is being suppressed by a world wide conspiracy of mathematicians--whom he is soon going to take down by destroying the University system so they all lose tenure. He also suspects that many top mathematicians may be aliens (from space), trying to destroy humanity.

    I don't have access to WolframAlpha, so have no idea what it would answer for "definition of mathematical proof", but I'd bet a large amount that it will not give a link to the aforementioned kook site.

    Google is a web search engine. It's job, which it does very well, is to index the web, and to find sites that appear relevant to a query, and then rank those based on how important they appear to be judged by what other sites reference them. The users of the web find crackpots more interesting than mathematicians, so kook math sites rank high.

    WolframAlpha is not a web search engine. It's job is to work with a large database of data that was collected and vetted by people for accuracy, and use that database to derive answers to questions.

    You can't meaningfully compare Google and WolframAlpha, because what they are meant to do is so different.
