Traditionally, this involved expert manual coding, translating detailed, often ambiguous job descriptions to standardized categories, a process both laborious and costly. However, recent advances in computational techniques offer efficient automated coding alternatives. Existing autocoding tools, including the O*NET-SOC AutoCoder, the NIOCCS AutoCoder, and the SOCcer AutoCoder, rely on supervised machine learning methods and string-matching algorithms. Yet these autocoders are not designed to understand semantic meanings in occupational write-in text. We develop a new autocoder based on Google’s Text-to-Text Transfer Transformer (T5) model. Like GPT and other large language models, T5 is pretrained on vast amounts of text data. We develop a T5-based occupational classifier (T5-OCC) model with fine-tuned model parameters and training data from occupation write-ins from the 2019 American Community Survey. By comparing our T5-OCC with existing methods, we show that the autocoding accuracy rate increases from 61 .8% to 71 . 1% . Considering the rapid change in neural language models, we conclude by offering suggestions on how to adapt our method for the development of occupational autocoding models in future research.  \n1 Introduction  \nCoding job descriptions into occupational categories is a common but challenging task for researchers, analysts, and organizations to classify job roles systematically (Cain and Treiman 1981; Miller, Treiman, Cain, and Roos 1980; Treiman 1979) . The process involves translating the detailed content of a job description, sometimes abridged and ambiguous, into a standardized occupational category. Traditionally, the gold standard for such occupational classification has been manual coding by expert coders. This approach involves a meticulous process where the coder begins by thoroughly reading the job description. Once familiarized with the content, the coder matches the job titles and duties specified in the description against predefined criteria in a chosen classification system. Based on this evaluation, the job description is matched with the most fitting category or code. Although this traditional approach can adeptly categorize a vast number of job descriptions into distinct occupations, spanning from a few to hundreds of categories, it is labor-intensive, time-consuming, and often costly.  \nWith the recent development of computational techniques for automated language understanding and production, automated coding methods become a useful alternative to the manual coding method (Census Bureau 2015) . These techniques stem from the fields of machine learning and artificial intelligence, s","cbCaitGprJFUa2qj","https://ap.wps.com/l/cbCaitGprJFUa2qj","pdf",1506674,51,"English","# Abstract\n# 1 Introduction\n## Background and manual coding\n## Automated coding with computational techniques\n## Paper overview and existing autocoding tools","[{\"question\":\"Why is coding job descriptions into occupational categories challenging?\",\"answer\":\"Job descriptions often contain detailed, ambiguous information, and mapping them to standardized categories is error-prone.
