According to Techcrunch, Yahoo will start interpreting semantic information added to websites very soon. Yahoo being one of the big search engines, this will ensure that all those responsible for any web site that wants to be included in a meaningful way, will start adding semantic meta tags. Yahoo will be able to use these tags to understand the structure of the web site and will be able to present it in a way that makes more sense to us humans than the gobbledygook we sometimes are confronted with by search engines.
Of course this is not the same as semantic search, but it's a huge step forward towards actually being able to access and use the vast amount of knowledge that is now available on Internet.
