Between Subjectivity and Imposition: Power Dynamics in Data Annotation for Computer Vision
This paper by Miceli, Schuessler, and Yang provides a thorough investigation into the socio-economic and hierarchical structures influencing image data annotation as part of machine learning processes in industrial settings. The authors focus on the power dynamics that emerge in these contexts, challenging the notion of data annotation as a neutral practice by highlighting its deeply interpretative and systemic nature.
The research employs a constructivist grounded theory methodology, which includes several weeks of fieldwork at two data annotation companies and additional interviews with industry experts. This approach allows the authors to dig into the multi-layered reality of data annotation work. Unlike most prior investigations that centered on the cognitive biases of individual annotators as primary sources of labeling errors, this paper broadens the scope by exploring external structures and influences on the data annotation process.
Key findings highlight that annotators' subjectivity is not the sole factor influencing labeling outcomes. Instead, hierarchical power imbalances play a significant role. Client or management-imposed categories and standards drive the interpretation of images and subsequent annotations, frequently overriding annotators’ judgments. This imposition of meaning is often unconsciously accepted by annotators, who perceive the instructed classifications as self-evident truths rather than imposed constructs. The authors use Bourdieu's concept of symbolic power to frame these dynamics, arguing that they contribute to the naturalization of potentially arbitrary classifications within datasets.
The paper provides concrete examples from projects at the observed companies that reveal how layers of actors—ranging from annotators and quality assurance teams to managers and clients—participate in and influence the annotation process. This involvement further complicates accountability, as the iterative and hierarchical nature of the processes dilutes responsibility for the final quality and societal implications of the annotated data.
These insights hold profound implications. The findings suggest that the annotation industry's orientation towards efficiency and cost-effectiveness often neglects the ethical dimensions of data annotation. This omission can perpetuate discriminatory practices in machine learning systems if biases are systematically encoded into datasets.
Practically, the paper calls for comprehensive documentation of the annotation process, advocating for transparency about actors involved and rationale decisions behind dataset creations. Such measures could facilitate deliberative accountability and improve adherence to ethical and regulatory standards like GDPR.
Theoretically, the paper underscores the importance of considering power asymmetries in practices of data annotation and creation. Researchers are urged to employ similar perspectives in their inquiries into data-driven systems to uncover and address the deep-rooted biases that power imbalances can inscribe into technological frameworks.
In conclusion, this paper underscores the potency of power dynamics in shaping both the practice and outputs of data annotation, challenging AI researchers and practitioners to rethink and refine their approaches to ensure equitable and accountable machine learning systems.
