Whereas most of the linguistic information is already machine-readable, we found that morphological information is mostly absent or only contained in semi-structured strings. An integration of morphemic data has not yet been undertaken due to the lack of existing domain-specific ontologies and explicit morphemic data. In this paper, we present the Multilingual Morpheme Ontology called MMoOn Core which can be regarded as the first comprehensive ontology for the linguistic domain of morphological language data. It will be described how crucial concepts like morphs, morphemes, word forms and meanings are represented and interrelated and how language-specific morpheme inventories can be created as a new possibility of morphological datasets. The aim of the MMoOn Core ontology is to serve as a shared semantic model for linguists and NLP researchers alike to enable the creation, conversion, exchange, reuse and enrichment of morphological language data across different data-dependent language sciences. Therefore, various use cases are illustrated to draw attention to the cross-disciplinary potential which can be realized with the MMoOn Core ontology in the context of the existing Linguistic Linked Data research landscape.<\/jats:p>","DOI":"10.3233\/sw-200412","type":"journal-article","created":{"date-parts":[[2020,11,27]],"date-time":"2020-11-27T11:17:43Z","timestamp":1606475863000},"page":"813-841","source":"Crossref","is-referenced-by-count":3,"title":["MMoOn Core\u00a0\u2013 the Multilingual Morpheme Ontology"],"prefix":"10.1177","volume":"12","author":[{"given":"Bettina","family":"Klimek","sequence":"first","affiliation":[{"name":"KILT Research Group, Institut f\u00fcr Angewandte Informatik (InfAI e.V.), Universit\u00e4t Leipzig, Germany.
