Abstract

Automatic morphological processing can aid downstream natural language processing applications, especially for low-resource languages, and assist language documentation efforts for endangered languages.Having long been multilingual, the field of computational morphology is increasingly moving towards approaches suitable for languages with minimal or no annotated resources.First, we survey recent developments in computational morphology with a focus on low-resource languages.Second, we argue that the field is ready to tackle the logical next challenge: understanding a language's morphology from raw text alone.We perform an empirical study on a truly unsupervised version of the paradigm completion task and show that, while existing state-of-the-art models bridged by two newly proposed models we devise perform reasonably, there is still much room for improvement.The stakes are high: solving this task will increase the language coverage of morphological resources by a number of magnitudes.

  • Linguistic characteristics such as rich morphology, writing-system variation, and limited standardized tools further degrade retrieval performance for low-resource languages.

    “linguistic characteristics such as rich morphology, writing-system variation, and limited standardized tools further degrade retrieval performance (Wiemerslage et al., 2022).”

    From Improving Amharic Information Retrieval with Translative and Multi-Agent Debate Retrieval Augmented Generation (2026) · cites this paper as Wiemerslage et al., 2022

    The Introduction says morphological resources for low-resource languages are often small or nonexistent, and Section 4.2 notes orthographic diversity among the languages studied. But the paper does not show that rich morphology, writing-system variation, or a lack of standardized tools degrades information-retrieval performance; its reported performance concerns morphological processing.

  • Applying RAG to low-resource languages presents unique challenges, including poor embedding representations, low retrieval quality, and semantic gaps caused by scarcity of digital documents.

    From Improving Amharic Information Retrieval with Translative and Multi-Agent Debate Retrieval Augmented Generation (2026) · cites this paper as Wiemerslage et al., 2022

    The Abstract and Introduction discuss limited morphological resources for low-resource languages, not retrieval-augmented generation. Searches for RAG, embedding representations, retrieval quality, and scarcity of digital documents found no passage in our copy addressing the claimed RAG challenges. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
