    Metaweb video - Freebase

    On July 16th 2010, when Metaweb announced their acquisition by Google, they also launched a video that explains what Metaweb/Freebase does, what entities are, etc.

    Video Transcript

    You know what drives me crazy about words? They have a million different meanings.

    Like, check this out: someone says, "I love Boston." Now, they probably mean, "I love Boston, the big city in Massachusetts", but they could be referring to one of the twenty-six other Bostons that are scattered around the globe. But, if it's during the playoffs, they're probably referring to the Celtics [basketball team]. Of course, you and I both hope that they're talking about the Boston. You know. [Image of rock band, sounds of electric guitar.]

    But, I guess there's really no way of knowing. The problem is that the same word can mean so many different things. Because of that, when it comes to finding, linking, reconciling, or organising multiple layers of information, words are not the best solution. The guys at grocery stores figured this out back in the sixties when they started putting barcodes on everything, so that products with the same name wouldn't get confused.

    So how come on the web, so many sites still try to organise stuff with words? Say you're a product guy at a big music site and you want to pull in feeds of lyrics and videos and photos from all of your data suppliers. But everyone uses different names for things, and a lot of the feeds don't even match up, so you've got to reconcile them, and pull in updates, and deal with merges and deletes and splits. It's a nightmare.

    But what if there was a better way?

    Welcome to Metaweb. Metaweb is a service that helps you build your website around entities, and not just words. Whoa, what's an entity? Well the simple answer is, it's a singular person, place, or thing.

    OK, well, let's compare that to text. Did you know that on the web there are more than 50 different ways people write "U. C. Berkeley"? [Examples listed: Cal Berkeley, Berkeley University, UCB, California, U of Cal, etc.] And they're really just talking about one single place, one entity. By mapping all those words to a single entity, as if it had its own barcode, you can combine all that information about U. C. Berkeley into one place.

    But that's just the beginning. Because entities represent unique, real-life things, we can build a map that shows how they're related. So, you can look for things that share certain attributes, like "actresses under 20 from New York". Can you imagine trying to find that with a keyword search? [Shows typical keyword search results, with keywords highlighted: "NY blogger under fire for criticizing actress", "March 3 2004: New! 20 steps to be an actress", "Kid actress eats 20 York peppermints".] Entities are just smarter than words.

    So, Metaweb's been in the process of identifying millions of these entities and mapping out how they're related, and what words other sites use to refer to them. And it's really cool because they have a totally collaborative process that involves the online community. This thing will always be expanding and improving.

    So, how is this going to help you? Well let's say you're that guy writing the movie review. If you tag the review with an entity in Metaweb, it's like you're looking at a menu saying, "Hey, Metaweb, give me the movie poster and a trailer and some links and maybe some other information like the release date and who was in it." And BAM, it'd be right there. And now, your page looks awesome!

    Or, say you're that product guy at the music site. Instead of spending months doing messy integrations and maintaining all those feeds, you can just plug in to Metaweb, and suddenly everything just works. It's like a switchboard for content on the web. [Various logos related to web content: eg. Twitter, Facebook, Audio Scrobbler, Wordpress.] And not only that! When your site's built on entities, new things get magically connected. Like, if one of your users adds a band to her profile page, or tags them in a comment, that can show up on the band page, because they're all linked under the hood to the same entity.

    Are you kidding me? This stuff sounds impossible! Well, that's what they said about the barcode.

    And it's not just movies and bands. Metaweb has millions of entities in thousands of categories: twelve million and counting!

    Metaweb makes your site smarter. It's time to connect to the web. Metaweb.com.

    Así comienza el comunicado oficial de Google sobre la compra de Metaweb del pasado 16 de Julio:

    7/16/2010 10:38:00 AM

    Over time we’ve improved search by deepening our understanding of queries and web pages. The web isn’t merely words—it’s information about things in the real world, and understanding the relationships between real-world entities can help us deliver relevant information more quickly. Today, we’ve acquired Metaweb, a company that maintains an open database of things in the world. Working together we want to improve search and make the web richer and more meaningful for everyone.

    Freebase es una base de datos social abierta con más de 10.000.000 de conceptos interconectados. El producto pertenece a Metaweb Technologies, empresa creada en 2005 con base en San Francisco. Este es su primer producto. Entre sus usuarios cabe destacar a Bing o Zemanta. Muy interesante para los que trabajan en la creación de contextos web semánticamente enriquecidos.

    "Freebase, created by Metaweb Technologies, is an open database of the world’s information. It’s built by the community and for the community – free for anyone to query, contribute to, build applications on top of, or integrate into their websites.

    Already, Freebase covers millions of topics in hundreds of categories. Drawing from large open data sets like Wikipedia, MusicBrainz, and the SEC archives, it contains structured information on many popular topics, including movies, music, people and locations – all reconciled and freely available via an open API. This information is supplemented by the efforts of a passionate global community of users who are working together to add structured information on everything from philosophy to European railway stations to the chemical properties of common food ingredients"

    By structuring the world’s data in this manner, the Freebase community is creating a global resource that will one day allow people and machines everywhere to access information far more easily and quickly than they can today"
