Examining AI's Role in Place Identity

In a detailed investigation documented in the journal Humanities and Social Sciences Communications, researchers evaluated how generative artificial intelligence (AI) models, specifically ChatGPT and DALL·E2, can encapsulate the essence of a city's identity through both textual and visual forms. This study marks one of the initial efforts to analyze how these AI models can mimic the urban landscape alongside the culturally significant meanings attached to specific places.

Utilizing Generative AI

The researchers employed a dual-phase computational approach aimed at investigating place identity. The methodology involved:

1. Dataset Creation: Using ChatGPT to produce text descriptions of cities and DALL·E2 to generate visual representations of streetscapes.
2. Validation of Outputs: Implementing a cross-validation process that compares the generated text and images to real-world data drawn from sources like Wikipedia and Google Images. This validation relied on two primary measurement techniques:
• Text Similarity: Evaluated using cosine similarity scores.
• Image Similarity: Assessed using the Learned Perceptual Image Patch Similarity (LPIPS) metric.

Additionally, a human-in-the-loop method was integrated, incorporating surveys to gauge perceptions of how closely AI images resemble actual visuals from various locales.

Insights from Textual Data

The research analyzed outputs from ChatGPT to gauge its effectiveness in portraying place identity, a concept that encapsulates the unique traits of a location shaped by its social, cultural, and historical context. Key findings include:

• The model exhibited substantial proficiency, yet often generated text dependent on initial statistical trends, which raises questions around reliability, particularly regarding nuanced constructs like place identity.
• ChatGPT's textual output was compared against content from Wikipedia, revealing moderate correlation with similarity scores falling between 0.56 and 0.59.

Visual Analysis with DALL·E2

Parallel assessments were conducted on visuals produced by DALL·E2. Highlights of this segment include:

• Images generated by the AI varied in similarity to actual city images, with perceptual score averages around 0.575.
• The model effectively created contextually relevant and recognizably visual outputs; however, limitations were acknowledged including the absence of definitive ground-truth datasets and varying lengths in generated versus actual content.

Unique Representation of Urban Landscapes

Findings indicated that while generative AI can adeptly capture notable urban features and styles, it sometimes produces generic scenes that fail to reflect a city's unique identity markers. For example:

• DALL·E2 accurately portrayed iconic elements of cities such as New York and Paris.
• Conversely, it struggled with cities like Tokyo, resulting in illustrations that were more generalized and less representative of the city's distinct characteristics.

Ethical Considerations and Moving Forward

The research raised important ethical concerns, particularly in terms of potential biases when representing diverse communities, emphasizing the necessity of revisiting training data—especially from sources like Wikipedia—to avoid circularity in representation.

Recommendations for enhancement included:

• Improved techniques in prompt engineering.
• Utilization of alternative and broader data sources, such as social media, to incorporate a wider variety of perspectives.
• Addressing language barriers in upcoming research to ensure diverse and inclusive outcomes.
