Extraction of knowledge graphs

Illustrate connections in functions from specifications related to the product family.

  • Extract common functions from text in system specifications by analysis of their relationships with domain knowledge.
  • Apply this technology to modular design particularly in derivative system development.


  • Design and development of increasingly diverse indent products; e.g., through derivative development
  • Standardization for modularizing product families
  • Inventory functions extracted from system specifications and other sources

Benchmarks, strengths, and track record

  • Semi-automated method in iterative learning way enables to achieve enough quality of the common functional structure in a short period.
