| Abstract: |
| When the temporal concept is introduced into the real-time expert system，how to represent the knowledge dealing with time(that is，temporal knowledge)should be concerned about deeply．Based upon the analysis of typical examples，the paper tackles three problems，such as the representation of real-time data，the representation of temporal knowledge，and the criteria to verify the temporal consistency in knowledge and facts during reasoning． |
| Key words: Artificial intelligence real time systems expert systems data processing knowledge representation temporal reasoning |
