The vision of a Semantic Web for life sciences alleviates these difficulties. A key technology for the Semantic Web are ontologies. In recent years many biomedical ontologies have been developed and many of these ontologies contain overlapping information. Often we would therefore want to be able to use multiple ontologies. For example, applications may need to use ontologies from different areas and from different views on one area. Ontology builders may want to create a new ontology using existing ontologies or combining knowledge from small ontologies. To obtain good results, we need to find the relationships between terms in the different ontologies, i.e. we need to align them. SIGNAL-ONTOLOGY (SigO) Aligning ontologies is to define the relations between the terms in different ontologies Aligning Ontologies • GENE ONTOLOGY (GO) Immune Response i- Allergic Response i- Antigen Processing and Presentation i- B Cell Activation i- B Cell Development i- Complement Signaling synonym complement activation i- Cytokine Response i- Immune Suppression i- Inflammation i- Intestinal Immunity i- Leukotriene Response i- Leukotriene Metabolism i- Natural Killer Cell Response i- T Cell Activation i- T Cell Development i- T Cell Selection in Thymus equivalent concepts equivalent relations is-a relation immune response i- acute-phase response i- anaphylaxis i- antigen presentation i- antigen processing i- cellular defense response i- cytokine metabolism i- cytokine biosynthesis synonym cytokine production … p- regulation of cytokine biosynthesis … … i- B-cell activation i- B-cell differentiation i- B-cell proliferation i- cellular defense response … i- T-cell activation i- activation of natural killer cell activity … An Ontology Alignment Framework Use as a basis for building ontology alignment systems Provide support for experimenting with different alignment strategies and their combinations Book Chapters: Lambrix P, Tan H, `Ontology alignment and merging', chapter in Burger, Davidson, Baldock, (eds), Anatomy Ontologies for Bioinformatics: Principles and Practice, Springer, 2007.
