• Abstract summary: We model the relationship between characters in a name and race and ethnicity using various techniques. A model using Long Short-Term Memory works best with out-of-sample accuracy of.85. The best-performing last-name model achieves out-of-sample accuracy of.81.

• Abstract: To answer questions about racial inequality and fairness, we often need a way to infer race and ethnicity from names. One way to infer race and ethnicity from names is by relying on the Census Bureau's list of popular last names. The list, however, suffers from at least three limitations: 1. it only contains last names, 2. it only includes popular last names, and 3. it is updated once every 10 years. To provide better generalization, and higher accuracy when first names are available, we model the relationship between characters in a name and race and ethnicity using various techniques. A model using Long Short-Term Memory works best with out-of-sample accuracy of .85. The best-performing last-name model achieves out-of-sample accuracy of .81. To illustrate the utility of the models, we apply them to campaign finance data to estimate the share of donations made by people of various racial groups, and to news data to estimate the coverage of various races and ethnicities in the news.

  Gender and race inferred from an individual's name are a notable source of stereotypes and biases that subtly influence social interactions. We show that our approach can detect name-based biases in both base and instruction-tuned models.

  This paper attempts to improve recognition of person names, a diverse category that can grow any time someone is born or changes their name. I look at names from 103 countries to compare how well the model performs on names from different cultures. I find that a model with combined character and word input outperforms word-only models and may improve on accuracy compared to classical NER models.

  We introduce a fully Bayesian Improved Surname Geocoding (fBISG) methodology that accounts for potential measurement error in Census counts. We supplement the Census surname data with additional data on last, first, and middle names taken from the voter files of six Southern states where self-reported race is available. Our empirical validation shows that the fBISG methodology and name supplements significantly improve the accuracy of race imputation across all racial groups, and especially for Asians.

  Pronoun Coreference Resolution (PCR) is the task of resolving pronominal expressions to all mentions they refer to. As one important natural language understanding (NLU) component, pronoun resolution is crucial for many downstream tasks and still challenging for existing models. We conduct extensive experiments to show that even though current models are achieving good performance on the standard evaluation set, they are still not ready to be used in real applications.
