2 years ago During the past year we:
- annotated pathway figures with disease and pathway ontologies
- performed Jaccard distance measures and hierarchical clustering on pathway figures in colab with Tina
To do:
- utilize these new clusters and distance metrics to explicitly annotate pathway figures (e.g., cluster IDs)
- utilize ontology and cluster annotations to define sub- and super-pathways sets
- add new sets to BTE
Similar to Gene Ontology, our collection of annotated pathway figures can be hierarchically organized, i.e., the contents of some figures partially overlap or are sometimes subsets of others. We should be able to use this information to define sub-pathway modules that are commonly represented, as well as super-pathway sets that share a common core. Such modules and sets will be analyzed by hierarchical clustering and distance measures such as Jaccard. The gene sets derived from this analysis would be valuable to capture and use as inferred pathway-based sets for query paths in BioThings Explorer. The hierarchical structure itself can be represented as an ontology. Likewise, other ontologies can be used to structure the content, including the Pathway Ontology (for figure annotations), Gene Ontology (for extracted genes) and MeSH (for extracted chemicals).
