Frame (artificial intelligence)
open-in-new
<p>Frames are an <a href="/facts/Artificial_intelligence/lJGauQwX">artificial intelligence</a> <a href="/facts/Data_structure/yNsNvL1I">data structure</a> used to divide <a href="/facts/Knowledge/joozoaup">knowledge</a> into substructures by representing "<a href="/facts/Stereotype/UDveLU8n">stereotyped</a> situations". </p><p>They were proposed by <a href="/facts/Marvin_Minsky/HTU5MYLL">Marvin Minsky</a> in his 1974 article "A Framework for Representing Knowledge". Frames are the primary data structure used in artificial intelligence frame languages; they are stored as <a href="/facts/Ontology_(information_science)/SQlhl6lp">ontologies</a> of <a href="/facts/Set_theory/1ptfsvUP">sets</a>. </p><p>Frames are also an extensive part of <a href="/facts/Knowledge_representation_and_reasoning/9lnzyILD">knowledge representation and reasoning</a> schemes. They were originally derived from <a href="/facts/Semantic_network/mt7FlP53">semantic networks</a> and are therefore part of structure-based <a href="/facts/Knowledge_representation_and_reasoning/9lnzyILD">knowledge representations</a>. </p><p>According to <a href="/facts/Stuart_J._Russell/f6EbRvSV">Russell</a> and <a href="/facts/Peter_Norvig/GkCUHH4H">Norvig</a>'s <i><a href="/facts/Artificial_Intelligence%3a_A_Modern_Approach/hPd3v5kh">Artificial Intelligence: A Modern Approach</a></i>, structural representations assemble "[...]facts about particular objects and event types and arrange the types into a large <a href="/facts/Taxonomy/QRvFI267">taxonomic</a> hierarchy analogous to a <a href="/facts/Biological_taxonomy/Qkg8wuyw">biological taxonomy</a>". </p>
