Similar to how Google, IBM Watson, and others have enabled developers of smartphone apps to incorporate, with only a few lines of code, complex machine-learning and artificial intelligence capabilities such as sentiment analysis, we aim to demonstrate how easy access to knowledge computing opens up new opportunities for analysis, tools, and research in comparative trait analysis. |

| − | [[Image:Ctol Logo.jpg|right]] [[Image:Zfinlogo.png|left]] We are addressing this by developing a database of evolutionarily variable morphological characters for a large clade of fishes (the Ostariophysi) and connecting this database to the large collection of mutant phenotypes in the [http://zfin.org ZFIN database], the central database of the zebrafish model organism community. The evolutionary and mutant phenotypes are being described using common [[#The_Role_of_Ontologies|ontologies]]. The database with its web-interface, called EQSYTE (Entity-Quality System for Trait Evolution), together with the extended ontologies and data curation tools, will allow researchers to ask novel questions about the genetic and developmental regulation of evolutionary morphological transitions. Tool and database development are being guided by [http://en.wikipedia.org/wiki/Use_case use cases], or driving research questions, defined by the devo-evo community. These tools are being developed under an open-source, open-development model, and in such a way that they can be used for additional biological systems in the future.
| + | As driving biological research questions, we focus on addressing three long-standing limitations in comparative studies of trait evolution: recombining trait data, modeling trait evolution, and generating testable hypotheses for the drivers of trait adaptation. |

| − | ====Background====
| |
| | | | |
| − | Ontologies are constrained, structured vocabularies with well defined relationships among terms. Ontologies represent the knowledge-base of a particular discipline, and provide not only a mechanism for consistent annotation of data, but also greater interoperability among people and machines. The most widely used biological ontology is the [http://www.geneontology.org Gene Ontology], which is utilized to annotate molecular function, biological processes and subcellular localization to gene products from different organisms.

| − | [[Image:EAV4_layers_flat2.png|right|320px]] For model organisms : Approximately 500 mutant zebrafish lines (alleles) with over 660 annotated phenotypic characters from the jaw or gill arches (n=250), fins (n=210), axial skeleton (n=190) and other features (n=10) of the skeleton have been described. Researchers in the [http://www.zfin.org Zebrafish Information Network] (ZFIN) are annotating mutant phenotypes using the [http://obofoundry.org/cgi-bin/detail.cgi?id=zebrafish_anatomy&title=Zebrafish%20anatomy%20and%20development zebrafish anatomy ontology] and the [http://www.bioontology.org/wiki/index.php/PATO:Main_Page Phenotype And Trait Ontology] (PATO). PATO is a “universal” ontology of terms describing qualities (e.g. shape, color, size) that may be applied to any organism.

| − | ====Anatomical ontologies====
| |
| − | | |
| − | We have initiated a multi-species ontology for ostariophysan fishes, the Teleost Anatomy Ontology (TAO), which was initialized with the terms in the zebrafish anatomical ontology. The development of the TAO is currently focused on the skeletal system because it varies significantly across the Ostariophysi, is well-preserved in fossil specimens, and it is often the focus of morphologically-based evolutionary studies in ichthyology.
| |
| − | | |
| − | This multi-species anatomy ontology is being used in combination with the PATO ontology (see EQ format) to describe the comparative morphological characters. We have also developed a separate catalog of homology statements for entities within the TAO, so that individual investigators may select particular relationships based on evidence.
| |
| − | | |
| − | ====Taxonomic ontology====
| |
| − | | |
| − | Together with taxonomic experts, we are developing a taxonomic ontology (based on the [http://www.calacademy.org/RESEARCH/ichthyology/catalog/fishcatsearch.html Catalog of Fishes]) in order to relate species with particular characters and states. The taxonomic ontology will include nodes ancestral to the Ostariophysi as far back as the Vertebrata in order to associate certain anatomical terms with more inclusive clades than the Ostariophysi.

| − | | |
| − | ====Fish Morphology====
| |
| − | | |
| − | Although the comparative anatomy of fishes has been documented in the literature for several hundred years, it is not available in a computable format. A Data Curator will input morphological character data that is gleaned from the literature, culled by experts and the [http://www.deepfin.org/ ichthyological community]. Our goal is to [[Morphology|input approximately 4,000 morphological features]] in an “EQ” format ([[Media:TREE Mabee.pdf|Mabee et al. 2007a]]<!--; Mabee et al. 2007 in process-->) using a combination of ontologies.

Enabling Machine-actionable Semantics for Comparative Analysis of Trait Evolution
The current project of the Phenoscape team is Enabling Machine-actionable Semantics for Comparative Analysis of Trait Evolution (SCATE).
The objective is to create infrastructure that will provide comparative trait analysis tools easy access to algorithms powered by machine reasoning with the semantics of trait descriptions. Similar to how Google, IBM Watson, and others have enabled developers of smartphone apps to incorporate, with only a few lines of code, complex machine-learning and artificial intelligence capabilities such as sentiment analysis, we aim to demonstrate how easy access to knowledge computing opens up new opportunities for analysis, tools, and research in comparative trait analysis.
As driving biological research questions, we focus on addressing three long-standing limitations in comparative studies of trait evolution: recombining trait data, modeling trait evolution, and generating testable hypotheses for the drivers of trait adaptation.
SCATE is funded by NSF collaborative grants DBI-1661456 (Duke University), DBI-1661529 (Virginia Tech), DBI-1661516 (University of South Dakota), and DBI-1661356 (UNC Chapel Hill and RENCI) from Sep 1, 2017 to Aug 31, 2020.
