Frame-Based Systems (Minsky)

    <p class=default>
      
        Frame-based systems are knowledge representation systems that use 
      
      
        <i>frames,</i>
      
      
         a notion originally introduced by Marvin Minsky, as their primary means to represent 
        domain knowledge. A frame is a structure for representing a 
      
      
        <u>CONCEPT <hampton.html></u>
      
      
         or situation such as "living room" or "being in a living room." Attached to a frame are 
        several kinds of information, for instance, definitional and descriptive information and 
        how to use the frame. Based on the original proposal, several knowledge representation 
        systems have been built and the theory of frames has evolved. Important descendants of 
        frame-based representation formalisms are 
      
      
        <i>description logics </i>
      
      
        that capture the declarative part of frames using a logic-based semantics. Most of these 
        logics are decidable fragments of 
      
      
        <i>first order logic</i>
      
      
         and are very closely related to other formalisms such as modal logics and 
      
      
        <i>feature logics.</i>
