Frameworks such as Multidimensional Quality Metrics (MQM) provide detailed feedback on translation quality and can pinpoint concrete linguistic errors. The quality of a translation is, however, also closely tied to its utility in a particular use case. Many customers have highly subjective expectations of translation quality. Features such as register, discourse style and brand consistency can be difficult to accommodate given a broadly applied translation solution. In this presentation we will introduce the concept of Business Critical Errors (BCE). Adapted from MQM, the BCE framework provides a perspective on translation quality that allows us to be reactive and adaptive to expectation whilst also maintaining consistency in our translation evaluation. We will demonstrate tooling used at Unbabel that allows us to evaluate the performance of our MT models on BCE using specialized test suites as well as the ability of our AI evaluation models to successfully capture BCE information.

This paper illustrates a new evaluation framework developed at Unbabel for measuring the quality of source language text and its effect on both Machine Translation (MT) and Human Post-Edition (PE) performed by non-professional post-editors. We examine both agent and user-generated content from the Customer Support domain and propose that differentiating the two is crucial to obtaining high quality translation output. Furthermore, we present results of initial experimentation with a new evaluation typology based on the Multidimensional Quality Metrics (MQM) Framework Lommel et al., 2014), specifically tailored toward the evaluation of source language text. We show how the MQM Framework Lommel et al., 2014) can be adapted to assess errors of monolingual source texts and demonstrate how very specific source errors propagate to the MT and PE targets. Finally, we illustrate how MT systems are not robust enough to handle very specific source noise in the context of Customer Support data.
