CommonMorph: Participatory Morphological Documentation Platform
🤖 AI Summary
This work addresses the longstanding challenge of morphological annotation for low-resource languages, which has been hindered by a scarcity of linguistic experts and limited resources. The authors propose a three-tier collaborative platform that integrates expert-defined guidelines, contributor-driven data collection, and community-based validation. Innovatively combining active learning with cross-lingual transfer mechanisms, the platform substantially improves annotation efficiency. Designed to support diverse morphological types, it employs an open-source architecture and produces data compliant with the UniMorph standard. Already deployed and operational, the system effectively reduces manual annotation costs while enhancing both the preservation of linguistic diversity and the interoperability of natural language processing tools for underrepresented languages.
📝 Abstract
Collecting and annotating morphological data present significant challenges, requiring linguistic expertise, methodological rigour, and substantial resources. These barriers are particularly acute for low-resource languages and varieties. To accelerate this process, we introduce \texttt{CommonMorph}, a comprehensive platform that streamlines morphological data collection development through a three-tiered approach: expert linguistic definition, contributor elicitation, and community validation. The platform minimises manual work by incorporating active learning, annotation suggestions, and tools to import and adapt materials from related languages. It accommodates diverse morphological systems, including fusional, agglutinative, and root-and-pattern morphologies. Its open-source design and UniMorph-compatible outputs ensure accessibility and interoperability with NLP tools. Our platform is accessible at https://common-morph.com, offering a replicable model for preserving linguistic diversity through collaborative technology.
