Crowdsourcing Microdata for Cost-Effective and Reliable Lexicography

Lexicography has long faced the challenge of having too few specialists to document too many words in too many languages with too many linguistic features. Great dictionaries are invariably the product of many person-years of labor, whether the lifetime work of an individual or the lengthy collaboration of a team. Is it possible to use public contributions to vastly reduce the time and cost of producing a dictionary while ensuring high quality? Crowdsourcing, often seen as the solution for large-scale data acquisition or analysis, is fraught with problems in the context of lexicography. Language is not binary, so there may be no one right answer to say that a word “means” a particular definition, or that a word in one language “is” the same as a particular translation term. People may misinterpret instructions or misread terms or make typographical or conceptual errors. Some crowd members intentionally add bad data. Without a payment system, incentives for participation are slim; micro-payments introduce the incentive to maximize income over quality. Our project introduces a public interface that breaks lexicographic data collection into targeted microtasks, within a stimulating game environment on Facebook, phones, and the web. Players earn points for answers that win consensus. Validation is achieved by redundancy, while malicious users are detected through persistent deviations. Data can be collected for any language, in an integrated multilingual framework focused on the serial production of monolingual dictionaries linked at the concept level. Questions are sequential, first eliciting a lemma, then a definition, then other information, according to a prioritized concept list. The method can also be used to merge existing data sets. Intensive trials are currently underway in Vietnamese, with the inclusion of additional Asian languages an explicit objective.
