摘要: Motivation: High-density microarray technology permits the quantitative and simultaneous monitoring of thousands genes. The interpretation challenge is to extract relevant information from this large amount data. A growing variety statistical analysis approaches are available identify clusters genes that share common expression characteristics, but provide no regarding biological similarities within clusters. published literature provides a potential source assist in clustering results. Results: We describe data mining method uses indexing terms ('keywords') linked specific present view conceptual similarity cluster or group interest. takes advantage hierarchical nature Medical Subject Headings used index citations MEDLINE database, registry numbers applied enzymes.
