Article Synopsis
  • The text discusses the need for ontologies to standardize "modifiers" that describe phenotypic characters in scientific literature, highlighting their importance for converting narrative descriptions into computable data.
  • It outlines the development of two types of ontologies for modifiers based on frequency, certainty, degree, and coverage, aiming to establish relationships among these terms (e.g., understanding how "usually" relates to "rarely").
  • The two proposed ontology designs—a closed ordered list and an open ordered list—reflect different approaches to term classification and extensibility, and include insights from the analysis of 130 selected modifier terms from various taxonomic descriptions.

Phenotypes are used for a multitude of purposes such as defining species, reconstructing phylogenies, diagnosing diseases or improving crop and animal productivity, but most of this phenotypic data is published in free-text narratives that are not computable. This means that the complex relationship between the genome, the environment and phenotypes is largely inaccessible to analysis and important questions related to the evolution of organisms, their diseases or their response to climate change cannot be fully addressed. It takes great effort to manually convert free-text narratives to a computable format before they can be used in large-scale analyses.

Scholarly publications of biodiversity literature contain a vast amount of information in human readable format. The detailed morphological descriptions in these publications contain rich information that can be extracted to facilitate analysis and computational biology research. However, the idiosyncrasies of morphological descriptions still pose a number of challenges to machines.
