Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
A large number of studies in biology, including those involving phylogenetic trees reconstruction, result in the production of a huge amount of data e.g., phenotype descriptions, morphological data matrices, etc. Biologists increasingly face a challenge and opportunity of effectively discovering useful knowledge crossing and comparing several pieces of information, not always linked and integrated. Ontologies are one of the promising choices to address this challenge. However, the existing digital phenotypic descriptions are stored in semi-structured formats, making extensive use of natural language. This technical report is related to a research developed by us [1] to addresses this problem, adding an intermediate step between semi-structured phenotypic descriptions and ontologies. It remodels semi-structured descriptions to a graph abstraction in which the data are linked. Graph transformations subsidize the transition from semi-structured data representation to a more formalized representation with ontologies. The present technical report drills down implementation details of our system. It provides a module to ingest phylogenetic trees and phenotype descriptions represented in semi-structured formats into a graph database. Additionally, two approaches to combine distinct data sources are presented and an algorithm to trace changes in phylogenetic traits of trees. |
