'''Marked up''' using RDFa, factual '''statments''' can be '''extracted''' from text such that they can be transformed, queried, or used in inference chains.\n|}\n\n{| style=\"float: right; border: 1px solid #BBB; margin: .46em 0 0 .2em;\"\n|- \n| valign=\"top\" width=\"405px\" |[[File:Mapping-uni-hannover.jpg|400px]]<br /> \n<span style=\"font-size:8pt\">\n\"Modell zum Durchsto\u00dfverfahren der Perspektive nach Brunelleschi, gebaut nach den Darstellungen von Albrecht Duerer\". http://www.aida.uni-hannover.de/aida/max/70~Forschung/Darstellungsgrundlagen/\n</span>\n\n| valign=\"top\" width=\"405px\" |\nApart from telling what different things have to do with each other, relationship statements are also used to explain the degree and kind of '''similarity''' between things.\n\nSimilarity relationships are known as '''mappings''', a term borrowed from mathematics.
