Really like the vision approach to classifying web pages, I've been thinking google should add this to their algo for a while (if they havent already).

Classifying individual parts of pages (as Diffbot seems to be doing) is difficult, but I suspect google could take screenshots of pages reported as spam or whatever as one class and compare those to screenshots of pages w/high pr to get a pretty interesting classifier they could use as an extra datapoint. Could be an interesting experiment anyway, using data they've got lying around.

Wanted to thank the HN community for all your encouragement. I first released the Diffbot API as a "Show HN:" post last year (http://news.ycombinator.com/item?id=2310852). $2M+ and lots of hard work later, we're powering some of the largest destination sites out there like Stumbleupon and the new Digg.

Congrats! Diffbot offers very compelling technology. Incidentally, the infographic you created was gorgeous. Do you mind sharing who you used to create it?

Glad you liked that! That infographic was made by the multi-talented Dan Mayer, who we highly recommend. Check out his portfolio at http://danmayer.com

The visual analysis method looks very interesting Mike! Will you identify or extract information from pages with product info, events, food recipes or product reviews?

miket6• 14 years ago

yes, its on the roadmap. a full photo api is next.

wow, pretty cool. I wonder though is there much use for it outside of aggregate sites like digg? Even for a site like reddit, all the content is already split up into categories by users. While this is really cool, I'm not really seeing much use for it. What are some problems that this will solve?

miket6• 14 years ago

The most pressing problem that the page classifier solves is for the current community of developers using Diffbot. We only offer APIs at the moment for extracting information out of frontpages and article pages (see http://www.diffbot.com/our-apis/). While we'll be releasing more soon for the other page types that you see in the infographic chart, this limitation is a problem if, for example, you're passing in a photo page or recipe into the article API--you're not going to get an article back since its not appropriate. Having the technology to visually understand what the types of pages are allow us to route those requests.

Beyond that, it's useful for companies that perform analytics or use the information to do better search or auto-categorization.

Are you going to be releasing an events API in the near future? I've had an app idea banging around for a few months that this API would be perfect for.

I thought this was super-clever when I first came across DiffBot last year. Can't wait to see what they come out with next.

Keep it up!

I see some potential in ad tech.

How does caching works? Is there any focus on security? Multiple geolocations?

I liked the TOS :) ---- Diffbot.com is made available for personal, non-commercial, and commercial purposes. Services are provided as-is, and we do not make any guarantees on the quality or performance.

Conceptually I like the product, it's something I would consider paying for. But in practice it doesn't seem to perform that well. It misclassify things it should get right (article hosted on posterous; a youtube page; hacker news) and for some queries it just returns results for a completely different webpage.

The page tagging technology looks good though.

Thanks. Yes, the page classifier still does miss, which is why it's still in beta status and not fully in production as with our other APIs. Would love to hear about your use case.

what are the different types the page classifier returns?
