The article explains how an ontology—defining objects, relationships, constraints, and inferable boundaries within a domain—serves as a semantic control plane between the fact and action layers of an agent‑driven system, ensuring consistent interpretation, validation, and lifecycle management of business facts.
This article explains how OWL extends RDF to model domain ontologies, outlines its core concepts, sub‑languages, key reasoning features, tooling, typical applications such as knowledge graphs and AI, and discusses both its advantages and practical challenges.
This article walks you through why enterprise AI agents need a semantic ontology, explains TBox and ABox concepts, outlines a general modeling workflow, introduces RDF/OWL standards and tools like Protégé and reasoners, and provides a hands‑on example—including Python code with Owlready2—to create and test a business ontology for order‑expedition rules.
This article explains the fundamentals of knowledge graph representation, including entities, concepts, relationships, and triple structures, and provides step‑by‑step instructions for installing Neo4j, configuring Python with py2neo, and importing CSV‑based triples into a graph database for querying and reasoning.
This article introduces RDF and property graph models, explains the core goals of graph database storage, compares mainstream storage solutions such as array, linked‑list and LSM‑Tree approaches, and presents practical deployment experiences of the Galaxybase distributed graph database.
This article introduces the fundamentals of knowledge graphs, explores their research dimensions—including knowledge engineering, NLP, databases, and machine learning—examines graph database storage models, discusses their relevance to AI and big data, and showcases the authors' own graph‑based projects and case studies.
This article introduces the basic concepts of knowledge graphs, explores their research dimensions across knowledge engineering, natural language processing, databases and machine learning, discusses graph database storage models and their integration with artificial intelligence and big data, and presents related projects and real‑world case studies.
This article introduces graph databases, explains the subgraph‑matching problem, compares it with relational databases, discusses its computational complexity, and surveys backtracking and multi‑way join algorithms, worst‑case optimal joins, set‑intersection SIMD acceleration, and the gStore system’s research contributions.
iQIYI’s Qisou Knowledge Graph, built since 2015 through a five‑stage pipeline of schema modeling, multi‑source data acquisition, entity alignment fusion, JanusGraph‑HBase storage, and inference‑driven querying, now powers precise video search, intelligent Q&A, tag mining, and relationship‑based recommendation across its platform.
