# Ontologies to compare

Note that there is a good source for ontologies: the famous Swoogle.

Here are mostly plans for providing ontologies to compare:

## Available

A couple of ontologies `onto1` and `onto2` are available in the `rdf` directory for testing the current implementation.

## Planned

Current plan includes describing several bibliographic ontologies in OWL in order to benchmark alignment.

- format exmo: bib.dtd
- KA2
- VionDury
- BibTeX
- RAWeb
- OpenOffice.org
- BiblioML
- DocBook

## Resources

- The Web-Based Knowledge Representation Repository featuring 47 test ontologies on the same domain.
- The ontology translation source contains definitions for alignment results as well as some aligned ontologies.
- The Illinois Semantic Integration Archive provides a number of data sets for testing alignment algorithms.
- The pairs of the EON Ontology alignment contest contains 20 ontology pairs with reference alignments.
