Abstract:
Objective To develop a traceable cancer hallmark ontology with terminology including gene mutation,cancer hallmark,and cell line for knowledge integration,standardization,correlation,and discovery.Methods The Ontology Development 101 and the current ontology development methods were employed to determine the content coverage,structural layers,reusable terms,and new terms of the cancer hallmark ontology.Taking colorectal cancer as a study case,we extracted the knowledge related with colorectal cancer hallmarks using text mining and text classification technology from PubMed,and then formalized the extracted knowledge into the cancer hallmark ontology.Moreover,we made use of existing cancer hallmark evidence in Catalogue of Somatic Mutations in Cancer and further semantic retrieval to discover new knowledge.Results The established cancer hallmark ontology comprised 9910 classes and 6138 instances,which realized the semantic representation of 2310 article abstracts about colorectal cancer and 26 pieces of evidence about genes and their cancer hallmarks.Compared with the Catalogue of Somatic Mutations in Cancer,new evidence for more genes associated with colorectal cancer hallmarks was found based on cancer hallmark ontology.Conclusion This study is of great significance to the research on the cancer pathogenesis at the molecular level,the revealing of specific roles of genes and mutations in the occurrence of cancer,and the rapid knowledge discovery of cancer hallmarks.
