Abstract

While thousands of ontologies exist on the web, a unified sys-tem for handling online ontologies - in particular with respect to discov-ery, versioning, access, quality-control, mappings - has not yet surfacedand users of ontologies struggle with many challenges. In this paper, wepresent an online ontology interface and augmented archive called DB-pedia Archivo, that discovers, crawls, versions and archives ontologies onthe DBpedia Databus. Based on this versioned crawl, different features,quality measures and, if possible, fixes are deployed to handle and sta-bilize the changes in the found ontologies at web-scale. A comparison toexisting approaches and ontology repositories is given.

Abstract

A list of authorized terms and cross references associated with genre and physical description of graphic materials. Supplies a standardized vocabulary for cataloging and retrieval (for MARC format users: field 655 for genre headings and field 755 for physical description heading). Includes terms for pictorial types (e.g., cartoons, bird's-eye-views, perspective projections, advertisements, etc.) and physical characteristics (e.g., etchings, albumen prints, lantern slides, miniatures). Includes guidelines for application, a bibliography and scope notes

Abstract

We are proud to announce DBpedia Archivo (https://archivo.dbpedia.org) an augmented ontology archive and interface to implement FAIRer ontologies. Each ontology is rated with 4 stars measuring basic FAIR features. We discovered 890 ontologies reaching on average 1.95 out of 4 stars. Many of them have no or unclear licenses and have issues w.r.t. retrieval and parsing.
