I just tried myself an Powerset semantic search in action. The search result I got in general were rather positive, but I start thinking that most visitors of the current web is not really ready for real semantic search. What I am saying is that people trying this search as well as any other semantic search engine (Wikia, isn’t it?) try to ask for words, but not for complete sentence. I also think that it will take about a year when we can say that most of internet users (not geeks) understand what should they ask there for and HOW to complete the query to search engine. The site I have been reviewing was Powerlabs.
