Research on the construction of conceptual hierarchical model based on air pollution

Abstract In recent years, the problem of air pollution has become more and more serious, attracting close attention of mankind. The ontology system is constructed for the semantics of related words of air pollution to realize the sharing and standardization of semantics. Humans’ comments on the air conditions of the living environment are taken as corpus, and words related to air pollution are extracted from the corpus text to construct the ontology of air pollution. Divide the levels according to the attributes of air pollutants, and build and enrich the ontology system. This paper builds an ontology model based on air pollutants, divides hierarchical structure on the basis of concepts.
