Natural language processing (NLP) is a part of the artificial intelligence domain focused on communication between humans and computers. NLP attempts to address the inherent problem that while human communications are often ambiguous and imprecise, computers require unambiguous and precise messages to enable understanding. The accounting, auditing and finance domains frequently put forth textual documents intended to communicate a wide variety of messages, including, but not limited to, corporate financial performance, management's assessment of current and future firm performance, analysts' assessments of firm performance, domain standards and regulations as well as evidence of compliance with relevant standards and regulations. NLP applications have been used to mine these documents to obtain insights, make inferences and to create additional methodologies and artefacts to advance knowledge in accounting, auditing and finance. This paper synthesizes the extant literature in NLP in accounting, auditing and finance to establish the state of current knowledge and to identify paths for future research.of achieving human-like language processing for a range of tasks or applications' (Liddy, 2001). This implies, as demonstrated throughout this paper, that 'there are multiple methods or techniques from which to choose to accomplish a particular type of language analysis' (Liddy, 2001). We reference a variety of analytical methods that incorporate NLP data, at various 'levels of linguistic analysis' (Liddy, 2001). However, since 'NLP is considered a discipline within Artificial Intelligence (AI)' we focus most heavily on the AI-related applications of NLP (Liddy, 2001). Despite the plethora of analytical methods that are associated with and use data produced by NLP, it comprises a unique set of 'computational techniques' that should not be confused or conflated with the many analytical tools referenced in the text that follows.Fifty years ago Goldberg (1965) stated: 'it is scarcely an exaggeration to say that the problem of communication is the axial problem in accounting'. Accounting practice is replete with written documents intended to communicate such messages as, but not limited to: current accounting standards, past and expected future corporate performance (along multiple dimensions), policies and practices embodied by financial statements and the results of financial statement audits. The growth in digital and social media usage by businesses has further increased the volume of unstructured text documents. Since the dissemination of these documents and messages is now largely automated by and through computers, we believe that NLP research and applications have considerable potential to enhance communication in the areas of accounting, auditing and finance. Our paper is motivated by the desire to determine the state of the extant literature in NLP in accounting, auditing and finance so as to inform and guide future research efforts.
