...On the other hand, the drawback is that processing flexibility is sacrificed. Currently established knowledge representations include logical representations based on derivation principles, semantic networks and frames based on human memory models, objects that treat the target world as things, production systems that represent knowledge in an If-Then format, and blackboard models that handle multiple knowledge sources. All of these are based on the principles of symbol processing, but recently models such as neural networks, fuzzy logic, and genetic algorithms are often considered to be knowledge representation methods in a broad sense. ... *Some of the terminology explanations that refer to the "If-Then format" are listed below.

…一方,処理の柔軟性は犠牲にされるのが欠点である。 現在確立されている知識表現には,導出原理に基づく論理表現,人間の記憶モデルに基づく意味ネットワークやフレーム,対象世界をものとして扱うオブジェクト,If-Then形式で知識を表すプロダクションシステム,複数の知識源を扱う黒板モデルなどがある。これらはいずれも記号処理の原理に基づいているが,最近では,ニューラルネットワーク,ファジー論理,遺伝的アルゴリズムなどのモデルも広義の知識表現手段と考える場合が多い。… ※「If-Then 形式」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
