| Abstract: | Network technical and intelligent technical innovation computer application environment has become now developing research and new program. The effect can be produced based on the information automatic retrieval of the theme knowledge base of concept-grade. The theme knowledge base of concept-grade has been realized preliminarily in this paper studies and offers. The realization of relation word table algorithm has been designed. The relation database model on hierarchy index and automatic concept retrieval on the theme information have been studied. |
