Top 7 Semantic Search Engines As An Alternative To Google, Nancy Messieh, Make Use Of (May 1)
Most articles about semantic say the following - "Semantic search engines are able to understand the context in which the words are being used, resulting in smart, relevant results." I'm not so certain that they really deliver on that promise, Broad categorization - yes, specific understanding - no.
However, here is the list - the comments are mine.
+ Kngine - can pick out "concepts" - best on places and things
+ hakia - will group by Web, News, Blogs, Twitter, Image and Video - but so do many search engines today
+ Kosmix - my favourite - good on broad topics.
+ DuckDuckGo - another favourite - helps in choosing the meaning you want
+ Evri - very social
+ Powerset - great technology but limited to Wikipedia
+ Truevert - new to me and one to try - "All results are filtered and organized from one specific perspective – with the topic of environmental awareness in mind."
