Ontology Development Methodology on Nigeria Agriculture Domain

The current web is the collection of documents and the end-users search for these documents by asking the questions from search engines. Due to the complexity and diversity of large amount of knowledge and terminology, relevant data is difficult to locate and retrieve primarily due to varying formats, schemas and semantics which results to retrieval of documents that are irrelevant to what the user is searching. To address these problems, there is need to use Semantic Web technologies. Ontology is the main building block in achieving the goal of machine understandable web (Semantic Web). Despite the fact that several ontology engineering methodologies have been proposed by researchers, none of the methodologies has proven to be applicable universally due to the complex nature of natural language and because most of these methodologies are domain specific that cope with the challenges of individual domain.
