Conceptualizing Crop Life Cycle Events to Create a User Centered Ontology for Farmers

摘要

People need contextualized information and knowledge to make better decisions. In case of farmers, the information that they require is available through agricultural websites, agriculture department leaflets and mass media. However, available information and knowledge are general, incomplete, heterogeneous, and unstructured. Since the fanners need the information and knowledge within their own context and need to represent information in complete and structured manner we developed a farmer centered ontology in the domain of agriculture. Because of the data complexity of the relationships among various concepts, to attenuate the incompleteness of the data, and also to add semantics and background knowledge about the domain we have selected a logic based ontological approach to create our knowledge repository. In this study, we have investigated how to model the actual representation of the domain and its challenges. The internal evaluation has been done to test the usefulness of the ontology during the design process. We have developed the online knowledge base that can be queried based on the farmer context.
