Disease and Phenotype Track
The 2018 edition is composed by two tasks requiring the pairwise alignment of:
Currently, mappings between these ontologies are mostly curated by bioinformatics and disease experts who would benefit from automation of their workflows supported by implementation of ontology matching algorithms.
Table 1 summarizes the ontology versions and sources of the ontologies used in the OAEI 2018 (same as 2017). Note that the version and source of HP, MP, DOID and ORDO are different from the ones used in 2016.
We have extracted "baseline" reference alignments based on the available BioPortal mappings (July 8, 2017). Most of the BioPortal mappings are generated automatically by the LOOM system; which should only be considered as a baseline since it is incomplete or may contain erroneous mappings.
The ontologies and baseline mappings for the OAEI 2018 campaign can be downloaded as zip files: Phenotype2018_Ontologies.zip [25Mb] and Phenotype2018_BaselineMappingsBioPortal.zip [0.6Mb]. The OAEI 2018 campaign datasets can also be accessed via the SEALS platform (see dataset identifiers below).
Additionally, systems are also welcome to provide all pair of entities with some similarity. These pairs do not necessary need to represent equivalence or a narrower/broader correspondences between the entities, but entities that have some degree of similarity. System developers can submit these correspondences directly to ernesto [.] jimenez [.] ruiz [at] gmail [.] com (in OAEI-RDF Alignment format) or create a configuration flag in the SEALS package, e.g. flag "all_corresponences=true" outputs all pairs of entities with some similarity, while "all_corresponences=false" outputs only the correspondences to evaluate Precision and Recall against the reference alignment.
The evaluation of the Disease and Phenotype Track will be run with support of the SEALS infrastructure. This requires that you wrap your matching system in a way that allows us to execute it using the SEALS client (see OAEI 2018 evaluation details).
Required input for the SEALS OMT client:
This task consists of matching the HP (31,034 classes) and MP (30,273 entities) ontologies. The BioPortal-based alignment contains 696 mappings.
This task consists of matching the DOID (38,240 classes) and ORDO (13,504) ontologies. The BioPortal-based alignment contains 1,237 mappings.
