Title of Speech: DIKW-based knowledge graph for AIoT in agriculture

Abstract: The Artificial Intelligence of Things (AIoT), a combination of artificial intelligence technologies and the Internet of Things (IoT), is booming recently for more efficient IoT operations. The AIoT enhances human-machine interactions and data management. In agriculture, AIoT is especially complicated because of the numerous influencing factors such as temperature, humidity, nutrition, genotype, domain knowledge, etc. Therefore, efficient data integration in agriculture is still challenging. A knowledge graph enables data/knowledge integration and representation through multilateral logic relationships, and makes the information both human- and machine-readable. We suggest to develop knowledge graphs according to the Data, Information, Knowledge, and Wisdom or “DIKW” pyramid. The introduction of the DIKW-based knowledge graphs would help integrate agricultural data and experience/knowledge from different sources (e.g. IoT sensors, weather forecast, soil data, expert/grower experience, etc.) in various formats (e.g. data, photo, etc.). A dynamic graph database based on a DIKW hierarchy enables real-time data-knowledge interaction according to real-time inputs from sensors, which provides a basis for the AIoT for future agriculture practice.
