[en] The existing domain-related ontology and information service patterns are analyzed, and the main problems faced by the experimental scheme knowledge service were clarified. The ontology framework model for knowledge service of Bio-environmental Engineering was proposed from the aspects of experimental materials, experimental conditions and experimental instruments, and this ontology will be combined with existing knowledge organization systems to organize scientific and technological literatures, data and experimental schemes. With the similarity and priority calculation, it can improve the related domain research. (paper)

[en] The large number of areas of environmental technology is organised under 4.000 headwords. Under each headword the reader finds a detailed explanation of the facts. References indicate either synonyms or a more general term under which the headword is dealt with. (orig.)
