Google and Semantic Search

Google has added semantic search to its Web search engine, which will enable it to identify associations and concepts related to a query, thus improving the list of related search terms Google displays next to the results. "For example, if you search for 'principles of physics,' the algorithms understand that 'angular momentum,' 'special relativity,' 'big bang,' and 'quantum mechanic' are related terms that could help you find what you need," according to Google's Ori Allon and Ken Wilder.
