Ontology Alignment Evaluation Initiative - OAEI-2022 CampaignOAEI

Biodiversity and Ecology track (biodiv)

General description

The main aim of this track is to motivate and attract ontology matching systems to work on matching ontologies and thesauri used in the biodiversity and ecology domains. In the current edition, we decided to keep the matching task to find alignments between the Environment Ontology (ENVO) and the Semantic Web for Earth and Environment Technology Ontology (SWEET) as these two ontologies have frequent updates.

In 2020, we partnered with the AgroPortal project to include two new matching tasks involving important thesauri (originally developed in SKOS) in agronomy and environmental sciences: finding alignments between the AGROVOC thesaurus and US National Agricultural Library Thesaurus (NALT) and between the GEneral Multilingual Environmental Thesaurus (GEMET) and the Analysis and Experimentation on Ecosystems thesaurus (ANAEETHES).

We address since 2021, the alignment of two new biological taxonomies with rather different but complementary scopes: the well-known, world-wide NCBI taxonomy, and TAXREF-LD [3], a more fined-grained, manually curated taxonomy that spans French metropolitan and overseas territories. A challenging aspect is the discrepancies between (1) the size and scope of both taxonomies, and (2) the RDF model to account for taxonomy and nomenclatural information.

Dataset

The biodiv dataset (2 ontologies, 6 thesauri and 4 reference alignments together with modules for the bigger matching task) can be downloaded here.

The evaluation of the track will be run with support of the MELT framework. This requires that you wrap your matching system in a way that allows us to execute it using MELT (see MELT evaluation for OAEI 2022).

Some mappings in the reference alignments have been extracted from the ontology and thesauri source files publicly available. We therefore ask the competitors to use only the source files provided in the dataset archive and ignore the original source files (available on AgroPortal or anywhere else) in the alignment process (including as background knowledge).

Schedule

The schedule is available at the OAEI main page.
