Annotated Corpus of English–Ukrainian Simultaneous Interpreting with Cognitive Indices (2015–2025)

This dataset contains a small annotated corpus of English–Ukrainian simultaneous interpreting excerpts prepared for research in interpreting studies. The material was collected in the course of work on a dissertation devoted to cognitive processes in simultaneous interpreting. The corpus includes 200 short fragments reflecting typical situations of institutional and conference interpreting between 2015 and 2025. The examples are based on publicly available speeches, meetings, press briefings and conference recordings. In order to make the material comparable, the excerpts were normalized and formatted as separate research segments. Each segment is supplied with basic contextual information such as year, institutional domain, event type and interpreting direction (English–Ukrainian or Ukrainian–English). Reference links to public recordings are provided for orientation, although the corpus itself contains only short analytical fragments. In addition to the textual data, the dataset includes cognitive index annotation used in the analysis of interpreting performance. The indices (EVS, BKN, IR, IDA, KTI, IBS) were calculated for experimental and statistical analysis within a multidimensional model of interpreting processes. The dataset is intended for academic use in interpreting studies, translation research and corpus-based analysis.
