Interoperable Metadata Bridges to the wider Language Technology Ecosystem

Abstract

One of the objectives of the European Language Grid is to help overcome the fragmentation of the European Language Technology community by bringing together language resources and technologies, information about them, Language Technology consumers, providers and the wider public. This chapter describes the mechanisms ELG has put in place to build interoperable bridges to related initiatives, infrastructures, platforms and repositories in the wider Language Technology landscape. We focus on the different approaches implemented for the exchange of metadata records about, in a generic sense, resources and exemplify them with the help of four use cases through which the ELG catalogue has been further populated. The chapter presents the protocols used for the population processes as well as the adaptations of the ELG metadata schema and platform policies that proved necessary to be able to ingest these new records.

A Flexible, Extensible, Machine-Readable, Human-Intelligible, and Ontology-Agnostic Metadata Schema (OIMS)

“…The lack of structural metadata in an easily accessible way that allows searching high variety datasets is arguably the greatest challenge to turning existing data into new actionable information (Rasmussen, 2018). Metadata schemas tend to be focused on specific domains (Canham and Ohmann, 2016), stop at a very high conceptual level (Shukair et al, 2013) or focus on descriptive metadata with a fixed structure (Devare, 2017;Labropoulou et al, 2020). Specific metadata schemas exist for specific datasets.…”
