Someone's down-voted you without explanation, which is rather poor form. Entities in this case means extracting the text of the page - with nokogiri for example, or a variant of readability to get just the article - and then extracting things that are named in that text. I used a modded version of readability and a simple entity extractor in python on the article and got: 'Sudoku', 'Search', 'Google', 'SRE', 'Stanford', 'Freebase', 'OpenCalais', 'SWE', 'Metaweb', 'MIT', 'Wrong', 'HTML', 'Developer Relations', 'Interest', 'DON', 'True', 'CPU'. A great introduction to all this is the O'Reilly book Natural Language Processing with Python (free online[1]). [1]http://www.nltk.org/book http://www.nltk.org/book
