Visualization of ontologies through hypertrees

In this paper, we present the use of hypertree as a supporting tool for visualization of ontologies in agricultural domain. This kind of visualization technique was used in the Information Agency Project, in execution by the Brazilian Agricultural Research Corporation -- Embrapa. The project's aim is to provide an information dissemination system structured in accordance to the productive chains of given products. That structure was chosen because it reflects the natural way technicians use to interact whenever they are transferring knowledge back and forth with farmers.
