Yahoo! Search monkey API - CEBIT 2008 Presentation Transcript

  • 1. Starting to Monkey Around With Yahoo! Search Monkey “ You’ll never make a monkey out of me” CEBIT Turkey 2008 – Éric Daspet Original presentation by Neil Crosby (One of Yahoo!’s Monkeys in London)‏
  • 2. Who Am I ? Frontend engineer at Yahoo! but not in the Search Monkey team
  • 3. What is Search Monkey?
    • A way to create more interesting Search Results.
    • Enhanced results and Infobar.
    • Enhanced results fit a tight template, infobars can be far more freeform.
  • 4. Some Normal Search Results
  • 5. Monkey Monkey Monkey!
  • 6. Where does the data come from?
    • Microformats
    • RDFa
    • Or pull it in from the page using XSLT
  • 7. My First Monkey
    • Start with something containing microformats.
    • FaceBook’s public profile pages fit the bill.
    • We’ll build a monkey that shows the user’s profile picture.
    • Go to http://developer.search.yahoo.com/
  • 8. Starting your Monkey – Basic Info
    • Name
    • Description
    • Category (for gallery)‏
    • Icon (really important)‏
    • Don’t forget to agree to the T&C
  • 9. URLs
    • Use auto-generate first.
    • Then choose specific URL for first field.
    • First URL is used to generate previews in gallery.
  • 10. Data Services
    • We can ignore this for now since we’re using µformats that are built into Search Monkey.
  • 11. Appearance
    • This is where we’ll actually do some work.
    • You must change something from the default here.
  • 12. Using the right hand rail
    • +/- expands/contracts sections.
    • Clicking an item pastes that data into your PHP at the cursor.
  • 13. Making our changes
      • $ret['image']['src'] = Data::get('com.yahoo.uf.hcard/rel:Card/vcard:photo/@resource');
    • And that’s all there is to creating a simple monkey!
  • 14. Let others play with your monkey
    • Once you’re happy with your monkey, share it.
    • Let users add your monkey to their SERPs.
    • Share your source if you want to.
  • 15. Monkey 2: Robotic Monkey of Doom
    • We want a Flickr Monkey that:
      • Shows main/first photo on a page.
      • Includes relevant information about photo.
    • No relevant µformats on the page, so we need some XSLT.
    • Will be slower than pre-spidered µFormats.
    • We need to create a data service.
  • 16. Creating the Data Service
    • Starts the same as a µFormat Monkey does.
    • Basic Info.
    • URLs.
    • Trigger: *.flickr.com/photos/*
    • First test: http://www.flickr.com/photos/thevoicewithin/1276763134/
  • 17. Now for some XSLT
    • Scary, but not too scary
    • Be aware of allowable rel values – see documentation .
  • 18. XSLT First Pass
    • We want to extract an image URL and a description.
    • Assume the only page type is the single photo page for now.
    • Use Firebug and/or XPather in Firefox to work out XPaths to our required nodes.
  • 19. XSLT First Pass <?xml version=&quot;1.0&quot;?> <xsl:stylesheet xmlns:xsl=&quot;http://www.w3.org/1999/XSL/Transform&quot; version=&quot;1.0&quot;> <xsl:template match=&quot;/&quot;> <adjunctcontainer> <adjunct id=&quot;smid:{$smid}&quot; version=&quot;1.0&quot;> <item rel=&quot;rel:Photo&quot; resource=&quot;{//div[@class='photoImgDiv']/img[@class='reflect']/@src}&quot;> <meta property=&quot;dc:description&quot;> <xsl:value-of select=&quot;//div[@class='photoDescription']&quot;/> </meta> </item> </adjunct> </adjunctcontainer> </xsl:template> </xsl:stylesheet>
  • 20. Save & Refresh
    • Check that we don’t get any errors.
    • Then, back to the homepage.
  • 21. Making our Flickr Monkey
    • Give it a name
    • Trigger: *.flickr.com/photos/*
    • First Test: http://www.flickr.com/photos/thevoicewithin/1276763134/
  • 22. Flickr Monkey Data Services
    • “ Add More Data Services”
    • Because we’re using the same URL trigger for monkey and data source, the source shows up here
  • 23. Flickr Monkey Appearance
    • Point and click info from the data source.
      • $ret['summary'] = Data::get('smid: DATA_SRC_ID /rel:Photo/dc:description');
      • $ret['image']['src'] = Data::get('smid: DATA_SRC_ID /rel:Photo/@resource');
  • 24. But Flickr’s more complex than that!
    • Flickr doesn’t just have individual photo pages under *.flickr.com/photos/*
    • Also has tag, user, set etc pages.
    • We should handle this at our end, so users only have to add one monkey.
  • 25. Enter xsl:choose
    • Allows if-elseif-else statements in XSL.
      • <xsl:choose>
      • <xsl:when test=&quot;some_test&quot;>
      • <item>...</item>
      • </xsl:when>
      • <xsl:when test=&quot;some_other_test&quot;>
      • <item>...</item>
      • </xsl:when>
      • <xsl:otherwise>
      • <item>...</item>
      • </xsl:otherwise>
      • </xsl:choose>
  • 26. Here’s one I made earlier
    • http://gallery.search.yahoo.com/application?smid=w4q.s (source available)‏
  • 27. And we’re done…
    • There’s lots more you can go away and do.
    • We haven’t even looked at infobars.
    • You can also fiddle with web services.
    • There’s a whole world of opportunity.
