Re: Yahoo RDFa enahced results example

Hi Juan, Eugenio:

>Where can we see search results in Yahoo that come from the RDF of Bestbuy
>and Goodrelations?

First, note that currently, only the standard Yahoo search results are 
by default enhanced by structured meta-data, i.e., you do not appear in 
the "local business" directory by Yahoo automatically. I spoke with 
Yahoo about that recently and they said that inclusion in those special 
Yahoo pages would be a future option, assumed that the amount of data 
out there is of sufficient quantity and quality.

You can check the appearance of a particular page using

    * wwwurl:<your uri>

as the search parameter at http://www.yahoo.com.

For example,

    * wwwurl:http://www.heppnetz.de/searchmonkey/company.html
    * wwwurl:http://www.heppnetz.de/searchmonkey/product.html
 
If you try that example, you already see the reviews meta-data displayed 
correctly, but the price and other details are missing. The reason is 
that the SearchMonkey index is not yet up-to-date; we fixed some bugs in 
the mark-up, but the crawler has not yet come back.

One problem with the SearchMonkey index and the underlying crawler is 
that, depending on the popularity of you page, the update cycles can be 
in the order of magnitude of weeks or even months.

If you want to check what meta-data is already included in the Yahoo! 
SearchMonkey index, you can use the tool at

http://goodrelations-search.appspot.com/

It is basically a variant of the Yahoo! search service that displays all 
meta-data that is found in the Yahoo! index.

Note: At the time of writing, there are some problems in Yahoo's RDF 
export, so even though my page has been crawled by Yahoo!, the 
SeachMonkey index does not return fully correct RDF. Yahoo is aware of 
the bug.

For links etc., see

As for BestBuy: BestBuy is currently only exposing RDF/XML, while Yahoo 
crawls only RDFa. So the BestBuy data is not yet in the SearchMonkey 
index (but in most other SemWeb indices).
There are two solutions to that:

a) Convert the RDF/XML into the Yahoo RDF2DataRSS tool at

http://www.ebusiness-unibw.org/tools/rdf2datarss/

and feed that into Yahoo using OPML.

b) Create RDFa snippets using our toll RDF2RDFa at

http://www.ebusiness-unibw.org/tools/rdf2rdfa

ans insert that into original pages or a second XHTML presence of the 
catalog.

We are in contact with BestBuy regarding that as a major showcase.
