"A semantics search engine attempts to make sense of search results based on context. It automatically identifies the concepts structuring the texts. For instance, if you search for 'election' a semantic search engine might retrieve documents containing the words 'vote', 'campaigning' and 'ballot', even if the word 'election' is not found in the source document.
An important part of this process is disambiguation, both of the queries and of the content on the web. What this means is that the search engine — through natural language processing — will know whether you are looking for a car or a big cat when you search for 'jaguar'."
