Semantic Search: Search for Meaning
The latest progress in web-based search industry is always one of my favourite areas of study. If you look through the related literature you can see various techniques claiming better search results. However, I think what we really need is new search engines which are able to make sense of what we ask them. This approach is called differently in various sources such as "Search 2.0" or "Semantic Search". Hakia compares this approach with the traditional indexing methods and concludes that: "Semantic search technology has many advantages compared to statistical (popularity) methods, especially when statistical data is not available such as in dynamic content and long-tail queries". I don't know how successful they have been in implementation of this new approach but for more information please have a look at this address.
