AgroPortal: A vocabulary and ontology repository for agronomy

In recent studies, Ontology construction plays an important role in translating raw text into useful knowledge. The proposed methodology supports efficient retrieval using multidimensional theory and implements integrated data training techniques before enter the trial process. The proposed approach has used the Semantic and Thematic Graph Generation Process to extract useful knowledge, and uses data mining techniques and web solutions to present knowledge as well as improve search speed and information retrieval accuracy. Established ontology can help clarify what it means for different ideas and relationships. Due to the rise of the ontology repository, the process of matching can take a long time. To avoid this, the method produces a hierarchical structure with in-depth interpretation of the data. A system is designed to remove domain dependencies using a dynamic labeling scheme using basic theorem, and the results show that it is possible to automatically and independently construct an independent domain

Configuration design lies in the later stage of the conceptual design. It affects the downstream of design process and decides product structure. Therefore, it is necessary to pursue an approach to support such design stage activities. Port, as the location of intended interaction, plays an important role in the configuration design, which abstractly represents the intended exchange of signals, energy or material in a convenient way. Ontology is an unambiguous and flexible semantic specification corresponding entities, and it can effectively describe the function of port. In this paper, we firstly give port concept and port functional description, and their semantic synthesis is used to describe port ontology. Second, we build an ontology repository which contains the assorted primitive concepts and primitive knowledge to map the component connections and interactions. Meanwhile we provide a model of port-based multi-views which contains functional view, behavior view and configuration view, and gives the attributes and taxonomy of ports. Next, a port-based ontology language (PBOL) is described to represent the process of port ontology refinement, and a port-based FBS modeling framework is presented to describe system configuration. Finally, a revised tape case is given to show the application of the port-based ontology.
