What is the difference between semantic search and semantic Web?
Apples and oranges. Semantic search is a centralized system where semantic knowledge is embedded. It can analyze any Web document free of format restrictions. Semantic Web is a new form of the Web. It assumes that people making the Web pages will organize the content following a specific format. I have never seen one single format to be followed by the masses. We have 200 different file formats for images, text, video, etc. Why would this stick now? It is an idealistic but impractical approach, unless the goal is a small segment of the Web via handful of followers.
