    Study Notes

    Enterprise Knowledge Graphs

    • Enterprise Knowledge Graphs (EKGs) represent a significant advancement in information architecture, enabling the breaking down of information silos and facilitating access and comprehension of information across an enterprise.
    • EKGs combine business data with explicit representations of knowledge, including definitions of business objects found across the enterprise.

    Graph Theory and Evolution

    • Graph theory, dating back to the 18th century, is a way of using mathematical structures to model the relationships between objects.
    • Advances in computing power have led to the development of modern graph theory practices, culminating in the birth of relational databases and application development.

    Enterprise Knowledge Graph Components

    • An EKG consists of two essential components: business data and an explicit representation of knowledge.
    • The graph model directly links the connections between data, allowing organizations to analyze and understand relationships via actual data.

    Concept of Relationships

    • Relationships in the knowledge graph help break down information silos.
    • Humans can manually find and determine relationships between data, but technology lacks the intelligence, context, and power of language to do so.
    • Encoding relationships in the EKG makes them machine-readable, harnessing native intelligence and advanced computing power.

    Modern Information Architecture

    • Modern organizations face exponential increases in data, complicated technology landscapes, and dispersed business lines.
    • EKGs help meet the requirements of seamless data connection, cross-functional analytics, and accurate results.

    Triple-Stores and Graph DBs

    • Graph databases, relying on triple-store technology, represent a different architecture than typical relational databases.
    • Triple-stores are based on ontologies, where concepts or objects are described as triples (subject, predicate, and object) with permanent unique resource identifiers (URIs).

    Building an EKG

    • Initial building blocks for an EKG include reference knowledge, comprised of tools like controlled vocabularies and taxonomies.
    • Standardized languages, such as SKOS and RDF, are used to express reference knowledge and ontologies.
    • Conceptual knowledge is built using ontologies, and data is added to complete the EKG.

    Accelerating into the EKG World

    • Organizations can accelerate into the EKG world by using existing standards, such as FIBO and LEI, and starting with specific use cases.
    • Use cases should involve constructing competency questions and determining if the knowledge graph is the best solution.

    Conclusion

    • EKGs offer a data-centric approach, shifting from application-centricity, to consolidate diverse data sources and break down information silos.
