The Zeno's Paradox of `Low-Resource' Languages (2410.20817v1)

Abstract: The disparity in the languages commonly studied in NLP is typically reflected by referring to languages as low vs high-resourced. However, there is limited consensus on what exactly qualifies as a low-resource language.' To understand how NLP papers define and studylow resource' languages, we qualitatively analyzed 150 papers from the ACL Anthology and popular speech-processing conferences that mention the keyword low-resource.' Based on our analysis, we show how several interacting axes contribute tolow-resourcedness' of a language and why that makes it difficult to track progress for each individual language. We hope our work (1) elicits explicit definitions of the terminology when it is used in papers and (2) provides grounding for the different axes to consider when connoting a language as low-resource.

• The paper qualitatively analyzes 150 studies to reveal significant heterogeneity in how 'low-resource' languages are defined within Natural Language Processing.
• It identifies four interrelated factors contributing to a language's low-resource status: socio-political issues, resource availability, linguistic and data artifacts, and community agency.
• The authors recommend adopting explicit, standardized definitions and fostering collaboration to enable more targeted interventions and equitable technological progress for underserved languages.

The Zeno's Paradox of 'Low-Resource' Languages

The paper "The Zeno's Paradox of 'Low-Resource' Languages" explores the complex and nuanced challenges associated with the classification and treatment of so-called 'low-resource' languages within the field of NLP. Authored by Hellina Hailu Nigatu and colleagues, this research performs a qualitative analysis of 150 academic papers to investigate how the term 'low-resource' is defined and applied, and to understand the broader implications of these definitions for languages underserved by the current trajectory of NLP advancements.

Overview of Findings

The paper identifies significant heterogeneity in what constitutes a 'low-resource' language, breaking down the concept into four primary interrelated aspects:

1. Socio-Political Factors: The authors argue that socio-political influences, such as historical marginalization and economic constraints, are crucial in determining a language's status as low-resource. These factors impact the availability of funding, media representation, and official recognition, all of which contribute to a language being overlooked by technology developers.
2. Resource Availability: This category addresses the availability of both human and digital resources critical for NLP application development. Differences in the number of native speakers, linguistic experts, and Internet presence greatly affect the categorization of languages as low-resource. Importantly, while some languages may have vast numbers of speakers, they may still lack digital resources due to socio-political neglect.
3. Artifacts: The focus here is on tangible outputs such as linguistic descriptions, data (both labeled and unlabeled), and computational tools. Languages often lack sufficient linguistic documentation and standardized orthographies, complicating automated processing.
4. Community Agency: The role of community agency encompasses the involvement of language-speaking communities in the creation of language technologies. The researchers emphasize that successful language technology should be developed with, and serve the purposes of, these communities, rather than being imposed from external perspectives.

Implications and Future Directions

The paper's findings underscore the critical need for precise terminology and a comprehensive understanding of what makes a language low-resource. Without these, tracking progress and designing appropriate solutions become inherently challenging. Furthermore, there is a risk that technologies developed for larger, well-resourced languages might be applied inappropriately to smaller languages without addressing specific community needs.

In practical terms, the authors recommend adopting explicit and standardized definitions for what constitutes 'low-resource' across academic and industrial discourse to better tailor initiatives to each language's unique circumstances. Such granular categorization would facilitate more targeted interventions, whether in data acquisition, tooling, or community engagement strategies.

On a theoretical level, the insights provided by this paper can guide the development of intervention strategies similar to those applied in socio-linguistics and computational linguistics that account for linguistic diversity, promoting inclusivity in technology design.

Concluding Thoughts

The analysis conducted in this paper highlights important pathways for future research in Artificial Intelligence and NLP. By addressing the disparities faced by low-resource languages and incorporating strategies that go beyond data availability, the field can work toward inclusivity. This necessitates genuine collaboration between linguistic communities, NLP researchers, and policymakers. As models and resources become more advanced and widely available, integrating the lessons from this paper could lead to more equitable technological progress in language processing.
