Abstract—Agriculture Information System. Existing agriculture information systems can meet general storage and general management requirements, however, on intensive management mode, users need to visit and gather resources and data in multiple heterogeneous information systems that distribute in different location of the web. These heterogeneous information systems not only have difference in platform construction, geography location, business logic storage mode, but also in area professional terminology. In this article, 3 levels of agriculture information systems integrated processing of systems heterogeneity, model heterogeneity and semantic heterogeneity were analyzed separately. Systems heterogeneity refers to different data sources of application system, database system, operation system and hardware platform; model heterogeneity means data sources differentiate in storage mode, semantic heterogeneity indicates information sources have differentiation in Semantics. Agriculture Information Bus (AI-Bus) model was proposed which including 4 levels that are service layer, protocol layer, < Final Year Projects > data layer and routing layer, and achieved rule oriented flexible mechanism, provided configurable process definition, heterogeneous differences of information system were diminished from systematic level and mode level. Since domain ontology has good concept layer structures and rich in semantic relationships, it is important in information resources gathering and knowledge expressing.
