Examining Expectations Around "Fair" or "Good" Behaviors in Natural Language Generation Systems

Q: How can NLG system designers navigate the tensions between invariance and adaptation when specifying desirable system behaviors?

In navigating the tensions between invariance and adaptation in NLG system behaviors, designers must first recognize the complexity of the issue. They need to understand that different social groups may have varying expectations and preferences regarding system behaviors. To address this, designers can adopt a flexible approach that allows for both invariance and adaptation based on the context and user needs. One strategy is to incorporate user feedback and preferences into the design process. By engaging with diverse stakeholders and gathering insights from different user groups, designers can better understand the range of expectations and tailor system behaviors accordingly. This participatory approach can help ensure that the system is responsive to the needs of its users. Designers should also consider the cultural and social implications of their design choices. They should be mindful of potential biases and stereotypes that may be perpetuated through system behaviors. By conducting thorough research and testing, designers can identify and address any harmful assumptions or biases in the system. Ultimately, a balanced approach that takes into account both invariance and adaptation is key. Designers should aim to create systems that are flexible enough to accommodate diverse user preferences while also maintaining consistency and fairness in their outputs.

Q: What are the potential harms and trade-offs associated with making identity-related assumptions in NLG system outputs?

Making identity-related assumptions in NLG system outputs can lead to a range of potential harms and trade-offs. One significant harm is the perpetuation of stereotypes and biases, where the system may reinforce existing societal prejudices based on gender, race, or other identity markers. This can result in discriminatory or offensive responses that alienate certain user groups. Another potential harm is the erasure of individual agency and autonomy. By making assumptions about a user's identity based on language features, the system may overlook the diverse and complex identities of individuals. This can lead to a lack of personalization and a one-size-fits-all approach that fails to meet the unique needs of users. Trade-offs may also arise in terms of usability and user experience. For example, overly adaptive systems that tailor responses too closely to identity markers may come across as intrusive or invasive. On the other hand, systems that are too invariant may miss opportunities for personalization and connection with users. Additionally, there is a risk of misinterpretation or miscommunication when making identity-related assumptions. Users may feel misunderstood or misrepresented if the system's outputs do not align with their self-perception or cultural background. This can lead to confusion, frustration, and a breakdown in communication. Overall, designers must carefully consider the potential harms and trade-offs associated with making identity-related assumptions in NLG system outputs and strive to mitigate these risks through inclusive and ethical design practices.

Q: How can participatory design methods involving diverse stakeholders inform the development of NLG systems that are responsive to varied user expectations and needs?

Participatory design methods involving diverse stakeholders play a crucial role in informing the development of NLG systems that are responsive to varied user expectations and needs. By engaging with a range of users, including those from different cultural backgrounds, identities, and experiences, designers can gain valuable insights that inform the design process. One key benefit of participatory design is the opportunity to incorporate diverse perspectives and preferences into the system development. By involving stakeholders in co-design activities, such as workshops, focus groups, and usability testing, designers can gather feedback on system behaviors, language choices, and user interactions. This input helps ensure that the system is inclusive and reflective of the needs of its users. Furthermore, participatory design fosters a sense of ownership and empowerment among stakeholders. By involving users in the design process, designers can build trust and collaboration, leading to more meaningful and user-centric outcomes. This approach also helps identify potential biases or assumptions in the system and allows for adjustments to be made based on user feedback. Incorporating participatory design methods can also enhance the usability and accessibility of NLG systems. By engaging with diverse stakeholders, designers can uncover usability issues, language barriers, or cultural sensitivities that may impact user experience. This information can then be used to refine the system and ensure that it meets the needs of all users. Overall, participatory design methods involving diverse stakeholders are essential for creating NLG systems that are responsive, inclusive, and user-centered. By prioritizing user input and collaboration, designers can develop systems that reflect the diversity of their user base and provide meaningful and engaging experiences for all users.

Core Concepts

Fairness-related assumptions about NLG system behaviors range from invariance, where systems are expected to behave identically for social groups, to adaptation, where behaviors should vary across them. This study examines these contrasting expectations through case studies that perturb different types of identity-related language features.

Abstract

This paper examines the tensions between invariance and adaptation in natural language generation (NLG) systems. The authors conduct five case studies that perturb different types of identity-related language features, such as names, roles, locations, dialect, and style, in NLG system inputs. Through these case studies, they observe actual system behaviors and examine people's expectations of system behaviors.

The key findings are:

Observed system behaviors can differ in terms of coherence, sentiment and affect, formality, textual complexity, and identity-related assumptions. Some systems also exhibit blocking behaviors in response to certain identity-related features.
People's expectations of system behaviors vary widely. Some favor adaptation to identity-related features to account for social norms, cultural differences, and feature-specific information. Others prefer invariance, citing reasons like prescriptivism, perceived unnecessary complexity of adaptation, and concerns about false assumptions.

The authors highlight the open challenges around specifying "fair" or "good" NLG system behaviors, as people have diverging views on whether systems should be invariant or adapt to identity-related language features.
