FIELD: information technology.SUBSTANCE: expert search engine has a knowledge base and a database, working memory, an inference engine which is connected by a two-way connection to first, second and third inputs/outputs, an explainer and a knowledge acquisition and accumulation unit, outputs of which are connected to the third and fourth inputs of the inference engine, and also connected by two-way connections to a user interface, the output of which is connected to a user terminal, an interaction unit whose input is connected to the fourth output of the inference engine. The expert search engine has a request unit, a load function unit, a control graph unit, a library unit, a conclusion completeness unit, a decision generating and justification unit which is interconnected by the input/output to the conclusion completeness unit. The output of the interaction unit is connected to the request unit, the output of which is connected to the first input of the load function unit. Its second input is connected to the first output of the decision generating and justification unit, and the output of the load function unit is connected to the input of the control graph unit, the output of which is connected to the library unit, the output of the latter being connected to the database. The fifth output of the inference engine is connected to the input of the conclusion completeness unit, and the decision generating and justification unit is connected by two-way connections to the knowledge acquisition and accumulation unit, which is connected by the third input/output to the user interface. The second output of the decision generating and justification unit is connected to the second input of the user terminal.EFFECT: high information value of expert systems owing to search for implicit knowledge of targeted hierarchical database structures of the expert system when producing aviation equipment.1 dwg |
