Description:  The Manchester OWL Corpus (MOWLCorp) is a filtered snapshot of ontologies on the web. In its original form (see main publication), the corpus was curated through a series of time consuming manual processes (mainly clustering by hand). For the  2014 edition of the corpus all manual interventions were omitted, sticking to a series of file based de-duplication processes. The corpus forms the basis of the Manchester OWL Repository.
