In the study of language, semantics refers to the meaning of words. Therefore, a "semantic search" will search and discover the meaning of words, unlike the typical search engine method of searching only for the occurrence of keyword(s) on a Web page.
A semantic search makes it easier to locate relevant information to the user's subject of interest, saving the user a lot of time reading through unrelated Web pages.
Known as the next generation in Web site search engine technology, every Web page indexed by a semantic search engine uses a unique set of tags. These tags go beyond providing keywords and descriptions, they provide content and relationships.
