Abstract
![CDATA[This study describes the mobile-based user needs-driven knowledge management system that supports the decision making process by considering user needs and preferences. Agriculture is one of the domains, in which, users seek specific information and knowledge relevant to their needs rather than searching and accessing general information from the Web, books, magazines or other information sources. Thus, the conceptualized solution was created by applying participatory sensing, natural language processing and ontology theories and techniques in a novel way in order to satisfy the user needs. The user-centered agriculture ontology that has been developed in our previous work is extended to make an up-to-date knowledge base by capturing user needs and preferences through participatory sensing. The methods of ontology evolution from unstructured data were analyzed to build a technique to enrich the user-centered ontology. The Modified Delphi method is used for verifying the correctness and relevancy of the ontology and the application-based evaluation is applied for checking the functional correctness of the system.]]
