Decision support method and apparatus for machinery control

A decision support apparatus for a machinery control system (MCS), comprising:

• a processor, a memory, and a data storage, wherein:
• the memory is configured to store computer-executable instructions;
• the data storage is configured to store a knowledge base including an SPO triples dataset;
• and
• the processor is coupled to the memory, and when the computer-executable instructions stored in the memory being executed, configured to perform a decision support method supported by the knowledge base in the data storage for machinery control, the decision support method including:
• extracting a plurality of entities from information sources;
• extracting a plurality of relations between the plurality of entities from the information sources;
• creating a plurality of SPO triples, wherein each SPO triple of the plurality of SPO triples includes a subject entity, an object entity, and a relation between the subject entity and the object entity, and the plurality of entities extracted from the information sources includes the subject entity and the object entity;
• constructing a KG based on the plurality of SPO triples, wherein the KG includes a plurality of nodes corresponding to the plurality of entities extracted from the information sources, and a plurality of links corresponding to the plurality of relations between the plurality of entities;
• designing new URL schemes vkel and vkrl for namespaces of the plurality of entities and the plurality of relationships in the extracted SPO triples;
• predicting missing links between the plurality of nodes and adding the predicted missing links to the KG;
• and
• performing diagnostic and prognostic analysis using the KG, including:
• analyzing plain text description of MCS situations to obtain relevant information concerning key components from the KG;
• recognizing sensor observations and component conditions to diagnose situations of other related components;
• and
• providing prognostics by analyzing a present trending/symptom in an MCS operating process.
