A Domain Knowledge Graph for Intelligent Knowledge Services in the Jujube Industry (2022-2024)

This dataset provides a comprehensive knowledge base for intelligent knowledge services in the jujube (Ziziphus jujuba) industry. It includes: (1) iteratively refined domain ontologies (OWL format) defining the semantic schema; (2) a Neo4j-exported knowledge graph containing entities, relationships, and attributes across the entire jujube lifecycle; (3) annotated corpus for training the BERT-BiLSTM-CRF extraction model; (4) sample Q&A pairs for system evaluation. The data supports research in agricultural knowledge engineering, semantic web, and intelligent decision-support systems.
