Weekly reading: Balhoff et al. on a semantic model for wasp species description

Following Daduhl et al. and Vogt et al., our third paper in the phenotype ontologies Weekly Discussion series will dive into an applied example by Balhoff and co-authors (mainly of the Deans Lab) with a clear taxonomic emphasis. Already we have seen that different scientific orientations draw on phenotype ontologies with the expectation of reframing and solving specific problem complexes.

Daduhl et al.‘s focus was firmly within the bounds of evolutionary and phylogenetic analyses of phenotypes across broader and deeper taxonomic scales. Implementation challenges notwithstanding, there was an underlying agreement that the legacy of phenotype-centric systematic work could be appropriated towards the outlined representation and inference goals.

Vogt et al., in turn, emphasized a need for consistent, machine-processable standards with regards to phenotype syntactics, semantics, etc.; including a separation of descriptive and evolutionary/explanatory elements in our morphological terminology. This has the makings of a potentially divergent paradigm in relation to Daduhl et al.‘s program and perspective.

Another interesting development is the Phenoscape team’s exploration of homology relations in ontologies, outlined here: http://phenoscape.org/wiki/Reasoning_over_homology_statements.

In light of these different lines of research, we set ourselves two immediate questions to address:

1. What are actual applications that utilize phenotype ontologies and (optionally) reasoning for (a) multi-taxon studies with (b) an evolutionary/systematic orientation?

2. Suppose we had the “awesome ontology & reasoning” infrastructure on hand, where current technological limits no longer apply. What kinds of questions would  we ask this infrastructure to solve for us (that cannot be addressed otherwise)?

The paper for next week applies directly to these questions.

Adding descriptions to Taxon Profile Pages in SCAN

This is a primer on adding (previously published) descriptions to Taxon Profile Pages in SCAN (or in Symbiota more generally). Examples are related to the Weevils of North America (WoNA) checklist. For sake of simplicity this entry uses descriptions that were previously digitized and are available through the Biodiversity Heritage Library.

Here is an exemplary, step-wise procedure to add a SCAN taxon description. Doing so requires permission to be a Taxon Profile Editor (such permissions are granted by portal administrators).
