In contrast, LLMs\u0000offer the potential for zero-shot and flexible network generation. However, two\u0000key questions are: (1) are LLM's generated networks realistic, and (2) what are\u0000risks of bias, given the importance of demographics in forming social ties? To\u0000answer these questions, we develop three prompting methods for network\u0000generation and compare the generated networks to real social networks. We find\u0000that more realistic networks are generated with \"local\" methods, where the LLM\u0000constructs relations for one persona at a time, compared to \"global\" methods\u0000that construct the entire network at once. We also find that the generated\u0000networks match real networks on many characteristics, including density,\u0000clustering, community structure, and degree.

A large\u0000literature has developed in two broad categories: antecedents of network\u0000structure, and network effects and outcomes. A new topic is emerging on network\u0000interventions that applies knowledge of network formation and effects to\u0000actively intervene in the social context of interaction. Yet, the question\u0000remains how might scholars deploy and determine the impact of network\u0000interventions. Inferential network analysis has primarily focused on\u0000statistical simulations of network distributions to produce probability\u0000estimates on parameters of interest in observed networks, e.g. ERGMs. There is\u0000less attention to design elements for causal inference in the network context,\u0000such as experimental interventions, randomization, control and comparison\u0000networks, and spillovers. We advance a number of important questions for\u0000network research, examine important inferential challenges and other issues\u0000related to inference in networks, and focus on a set of possible network\u0000inference models. We categorize models of network inference into (i)\u0000observational studies of networks, using descriptive and stochastic methods\u0000that lack intervention, randomization, or comparison networks; (ii) simulation\u0000studies that leverage computational resources for generating inference; (iii)\u0000natural network experiments, with unintentional network-based interventions;\u0000(iv) network field experiments, with designed interventions accompanied by\u0000comparison networks; and (v) laboratory experiments that design and implement\u0000randomization to treatment and control networks.

Prior research has often focused on\u0000isolated media bias dimensions such as textit{political bias} or\u0000textit{racial bias}, neglecting the complex interrelationships among various\u0000bias dimensions across different topic domains. Moreover, we observe that\u0000models trained on existing media bias benchmarks fail to generalize effectively\u0000on recent social media posts, particularly in certain bias identification\u0000tasks. This shortfall primarily arises because these benchmarks do not\u0000adequately reflect the rapidly evolving nature of social media content, which\u0000is characterized by shifting user behaviors and emerging trends. In response to\u0000these limitations, our research introduces a novel dataset collected from\u0000YouTube and Reddit over the past five years. Our dataset includes automated\u0000annotations for YouTube content across a broad spectrum of bias dimensions,\u0000such as gender, racial, and political biases, as well as hate speech, among\u0000others. It spans diverse domains including politics, sports, healthcare,\u0000education, and entertainment, reflecting the complex interplay of biases across\u0000different societal sectors. Through comprehensive statistical analysis, we\u0000identify significant differences in bias expression patterns and intra-domain\u0000bias correlations across these domains. By utilizing our understanding of the\u0000correlations among various bias dimensions, we lay the groundwork for creating\u0000advanced systems capable of detecting multiple biases simultaneously. Overall,\u0000our dataset advances the field of media bias identification, contributing to\u0000the development of tools that promote fairer media consumption.
