  1. What is a Frame Problem • Environment for an agent is not static • Identifying which things remain static in changing word • Use of information in Knowledge Base and agent’s conclusion based on that knowledge • Discarding negative inferences F r a m e P r o b l e m

  2. Origin of the Frame Problem • Fluents : Values that change over time • States : Current view of the environment • Predicates : Evaluates to true /false • Action : Causes change in state • Result : Through which inferences are drawn • Frame Axioms : phrases that describe the environment • HERE COMES THE PROBLEM OF INFERENCE F r a m e P r o b l e m

Problems in Frame Problem • Frame Problem is a temporal problem • Inferential Problem : How to judge the world • Raminification Problem : Deviation within the environment • Prediction Problem :Uncertainty for positive results • Qualification Problem: which rules qualify ? • Representation Problem : true knowledge repository F r a m e P r o b l e m

  4. Resolving Frame Problem • Agent must examine current facts • Relevant/Irrelevant Changes • Representing Facts: • Semantic : word – meaning pairs • Syntactic : structures and patterns • Problems with Fact Representation F r a m e P r o b l e m

  5. Requirements for Solution • Achieving right level of generality/speciality • Staying truthful to intuitions • Truth and Soundness • Concreteness F r a m e P r o b l e m

  6. Techniques for Solution Some of the methods for resolving : • Non-Deductive :emulate human actions • Deductive : Based on Logic • Frames and Scripts • Causal Approach • Probabilistic Approach F r a m e P r o b l e m
