I was lucky enough to get funding to go (without having sent a paper nor being an active participant in the research community) to the last day of WWW2009 Madrid!

Lucky indeed as I hadn't been before in such a global and well organized conference. I'm sure there were some problems (the people in charge apologized in the closing ceremony) but I personally didn't see any.

I went to the following talks:

- Invited talk about web infrastructure by Pablo Rodríguez the Internet Scientific Director at Telefonica. He explained the problems current internet architecture which mainly consist of obsolete, generic protocols, where distribution is hard. He suggested to specialize protocols (where you route content, not hosts) and push things down a layer or two (where every router has a terabyte storage to do an akamai-for-the-people).

- Invited talk about web search in web2.0 by Ricardo Baeza-Yates, VP of Research for Europe and Latin America at Yahoo!. He showed a pretty interesting summary of the recent research done by him and his team on searching text/images using mainly user generated content (tags, tags of objects in pictures). Summing up, using user generated content can enhance search results significantly.

And some highlights from the papers presentations:

- Social searching: Porqpine

- Synonym extraction: Ways to detect that queries like "vaio 720 laptop" and "vaio 720" are synonyms in an efficient way

- A framework to manage digital rights: Interesting idea, a good model to license, but sadly it requires everyone to use a centralized website and to download an extra application to access the actual content. It just doesn't pass the grandma test.

- A reference implementation of the web coverage processing service standard, Rasdaman (plus some web tools which use it to justify its presence on WWW)

- Leveraging web search engines to query databases: A clever approach to enhance search results with structured database results, typically useful when searching for entities which are usually in structured DBs (movies, electronic devices and so on)

- YUI 3. I wasn't present at the talk, but looks nice

All in all, it was a very good experience and I now have a CD with 215 pdf files to review (between papers and posters)... that's some hard work! If I manage to do any of it and see something worth, will comment on it. Pics here.
