MS Patent Applications Reveal Search Technology 87

eldavojohn writes, "In the roughly 90 patents they applied for on November 2, 2006, Microsoft reveals that it is apparently pushing its research in the search engine market. There are a few patents that reveal improved ranking methods and document classification but the real interesting ones revolve around linking related queries, optimizing search, identifying results that are spam, and using a Bayesian classifier to measure feedback from the user. If that's not enough, there's even a few I don't quite understand. Another notable Microsoft application for a patent is the model for assisting children in authoring stories so you can't accuse Microsoft of not thinking of the children. Microsoft regularly applies for many patents but never so many revolving around search."

    This patent [] sounds like they've patented the idea of recording which search links are clicked on most often for a given query, thus providing feedback given a random session number of which links you clicked on, and if you came back and tried something else.

    it would improve search results for future searchers, but I dunno if I like the idea of my search being tracked.

    Not only do my searched probably already get tracked without my knowledge but I might be completely wrong about this patent as I only perused it.

      But don't all search engines on the web track all searches? AOL [] comes to mind...
      • by Tokerat ( 150341 )
        Yes but do they do it using "sessions" -i.e. cookies- to see if the user returns to select a different link? This isn't "record what teh users are typing into the search box" this is "track what they click based on what they searched for and factor it into the rankings"

      That hyperlink that has "understand" as anchor text has NOTHING to do with searches, it's a database related patent (being from MS, we can safely assume it's a SQL Server related patent).

      And being on topic: everybody out there is already logging you, from your ISP, big brother, search engines, advertising sites/outlets, your various cards that give points at stores, you name it, you're being tracked. This is hardly worse. It's not like someone's going to sit there and manually check what you've clicked onto
      • ...your various cards that give points at stores, you name it, you're being tracked.

        Yes they are tracking me. that means that when i buy skippy peanut butter every time i am in there, and they scan my card, i get coupons for skippy peanut butter.

        point being: its like targeted advertising

        staying on topic: i use google logged in. i don't care. i don't agree with aol released their data the way they did, because it was still personally identifiable. but i don't mind people inside google using my data to bet

  • Does anyone use MS' web search page []? After its introduction with much noise I've never heard anything about that anymore.
    • I use Microsoft Live Search for all my web page searches.
            Reason being: to not use Google and support a large company's core-product that gives them their bread and butter of profit.
      M$ has got too much cash.
      However, using Microsoft search probably doesn't make a difference to them fiscally because it's scarcely used anyway: it's a side product for marketing that doesn't affect me.

    • It's the #2 search used, behind google and ahead of Yahoo. I don't know what the numbers are, though I suspect Google has a significant lead.
      • The numbers for MSN search are artificially inflated by the fact that IE is set (by default) to automatically do a search using MSN search, if the domain name in the address bar is not found. Of course, the same is true of Google and Firefox. The difference is that most Firefox users know this and use it as a feature. Mostly IE users have no idea why they get a completely different page to the one they intended.

            That may be. But how many non-false hits were unintentional and thus serving useless search information to someone that just says "whoops, I meant to type in the .com at the end" and ignores the results? Or better yet, how many hits resulted in an intentional search? *That* would be a more useful number. I've always had a problem with how folks quantify how well a thing is on the Internet by the number

              • > easy to spam

                I should maybe clarify that. The results put too much weight on blogs and on on-page factors such as keywords in the URL or domain name. This has been a constant theme for MSN search properties. The results are certainly different from Google but they are not better quality.

    • I don't know, but I'm starting to think that nearly anything is better than google. 8 of the first 10 results usually end up being spam mini-search engines that have nothing to do with the product "you can purchase ___enter whatever your search term was here___ for half-cost!".

    Software patents are proved that they are needless and very anticompetitive. They must go. Period.

    I decided to post this under EVERY article about software patents, because no matter how good or bad example is, truth usually is that this patent will be never used in it's meant way. Can call me a troll, but after all sharade of Microsoft/Novell deal, after EU/EC fiasco, after all copyright extentions I have enough.

    I call for political change in this field. Like it or not, guys, we must fight. And no more arguing that some software patents must be good, otherwise such silly concept would be never put into realisation, right?

    And no more buts and "ohhs" and "but lobbies are too strong". I have never seen sysadmins and other IT people marching and protesting about ANY issue. We just wine and cry and when everything is happening in bad way, we all say "I told you so."

    Not any more. At least, for me. Let's do it guys. Let's work for a change. You can support fight in Europe ( []) or you can try to build consensus and inform people in your home. Inform people in polite way about the issue, don't force point of view. Describe what consequences are here for all that.
