Levels

Maturity Level 1

  • Business terms for EKG use cases are captured and mapped to an ontology (possibly as simple labels)

Maturity Level 2

  • Relevant terms (for EKG use cases) are associated with the use case independently of their corresponding ontologies

Maturity Level 3

  • Existing glossaries within the organization, within the scope of supported use cases, are mapped to ontologies and imported into the EKG
  • Terms are grouped into vocabularies for reuse in different communities
  • Vocabularies include local textual definitions as well as being mapped to ontologies
  • Community level vocabularies able to import common vocabularies reusable in many communities: allow for multiple levels from local to global
  • Support for synonyms and abbreviations within vocabularies
  • Vocabularies use general principles of modularity
  • Ontologies presented to different communities in their own language
  • Natural language used for definitions links to other terms used
  • Terms are searchable via the knowledge graph interface
  • Generate vocabularies from existing data models or ontologies
  • Ontology logic is presented to business users as natural language

Maturity Level 4

  • Ontology logic is presented to business as natural language
  • EKG is the authoritative source for all terms, scoped by community, context and use case
  • The governance processes for all new terms (and changes) are managed directly within the EKG
  • The results of ontology inferencing are presented in business natural language
  • Use of ontology logic to validate use of vocabulary terms
  • Management of homonyms and disambiguation of terms---through being mapped to different concepts
  • Use of business terms in natural language queries
  • Techniques for disambiguation e.g. allowing business users to select the intended meaning
  • Use of textual analytics to suggest modifications to vocabulary/ontology (lemmatization)
  • Use of vocabularies to match internal databases or external data sources for linked data, and establish sameAs links

Maturity Level 5

  • Terminology is used to support natural language processing (NLP) of unstructured data for the EKG
  • Use of reference data from the EKG to support entity resolution (in EKG context or elsewhere)
