Construction of the knowledge service model of a port supply chain enterprise in a big data environment

In the context of the rapid development of big data and artificial intelligence, knowledge service theory and big data technology are applied to build a smart port supply chain knowledge service model. This model provides a personalized, intelligent, and diversified knowledge-based service system platform solution to port supply chain enterprises, helping to realize port supply chain transformation and upgrading and intelligent integrated operations. This paper analyses and summarizes the research status on knowledge service demand and port supply chain knowledge service during the development and operation of the port supply chain and applies big data and artificial intelligence technologies such as knowledge matching, knowledge fusion, and natural language processing. A port supply chain knowledge service model including knowledge acquisition, knowledge organization and knowledge service modules is constructed. The ontology method is used to construct the ontology knowledge base of the port supply chain, and based on this, computational reasoning experiments are performed. The experiments show that ontology technology demonstrates effectiveness and superiority in constructing a knowledge service system model for the port supply chain in terms of knowledge representation and knowledge reasoning.
