Finding Role Errors Of The Ncit Gene Hierarchy Using The Ncbi, Marc Oren

Theses

Due to the knowledge discovery process of gene information, details such as organism and chromosomal location should be known. Furthermore, the extensive biomedical research in genomics led to discovery of processes and diseases in which a gene plays a role. In the Gene hierarchy of the NCI Thesaurus (NCIT) such knowledge is represented by appropriate roles. However, upon review of the Gene hierarchy of the NCIT, many role errors are found. Realizing that such details are provided by another knowledge repository of NIH, the NCBI gene database, a methodology is presented to use NCBI to discover role errors for the …
