Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Functional genomics requires standardized biological data and knowledge representation.
  • The Gene Ontology (GO) is a key resource for annotating gene products.
  • Managing and developing the growing GO presents significant challenges.

Purpose of the Study:

  • To evaluate the suitability of the Protégé-2000 Knowledge Base Management System (KBMS) for GO maintenance and development.
  • To assess the capabilities of Protégé-2000 in handling the complexities of a large-scale biological ontology.

Main Methods:

  • The Gene Ontology (GO) was transferred to the Protégé-2000 platform.
  • Protégé-2000's graphical user interface was used for browsing and editing GO.
  • Ontological consistency was checked using the Protégé Axiom Language and PROMPT tools.

Main Results:

  • Protégé-2000 facilitated browsing and editing of the Gene Ontology.
  • Consistency checking tools identified minor inconsistencies and redundancy reduction opportunities within GO.
  • The system supported testing changes and extensions to GO, refining semantics and classification.

Conclusions:

  • Protégé-2000 is a suitable system for the maintenance and development of the Gene Ontology.
  • The KBMS aids in ensuring the consistency and improving the representation of biological knowledge.
  • This demonstrates a viable computational infrastructure solution for large biological ontologies.
