Case study · Knowledge graph

A knowledge graph to connect two departments and anticipate incidents

Two departments that did not speak the same language, a history of incidents to make use of, and one goal: predict new incidents, their root cause and their solution.

Key figures

  • 10distinct data sources consolidated in the graph
  • 5+connected applications drawing on the knowledge captured in the graph
  • 2use cases: capturing data and knowledge, then enriching it continuously through feedback from domain experts

Deliverables
  • A knowledge graph connecting two departments with different vocabularies
  • The incident history structured in the graph
  • A similarity search engine to find related incidents, their root cause and their solution
Technologies
  • Ontology (Protégé)
  • Graph database
  • Machine-learning similarity search

The challenge

Two departments worked on the same incidents without speaking the same language: different terms, reference data and tools. The incident history existed, but it was hard to use it to understand causes and prevent incidents from happening again.

The value delivered

DEEPXP modelled a shared ontology in Protégé that maps both departments’ vocabularies, then built a knowledge graph centred on the incident history. A machine-learning similarity search finds the past incidents closest to a new one, with their root cause and the solution that was applied. A continuous improvement loop collects feedback from domain experts to enrich the knowledge in the graph.

Results

Both departments now share one view of incidents. When a new incident occurs, teams find similar cases, their likely root cause and the solutions already applied, instead of starting from scratch.
