Abstract

The study utilizes text classification (TC) to observe “interpretese” in simultaneous interpreting (SI) at United Nations Security Council conferences. “Interpretese” is a term coined to describe the distinctive linguistic patterns interpreters employ. A text vectorization method known as TF-IDF is improved with Shannon’s entropy and used to convert interpreted and non-interpreted target language speeches into vectors. Subsequently, stacking ensemble learning classifies the vectors reduced in dimensions into two labeled categories: interpreted speech and non-interpreted speech. Accurate classifications would support the interpretese hypothesis. To explore the universality of interpretese, this study detects interpretese in bidirectional SI when interpreters work from their first to second languages in one direction and from their second to first languages in the other direction. The results demonstrate successful classifications in the two interpreting directions, thereby supporting the interpretese hypothesis. Notably, a higher classification accuracy score is yielded when the interpreters work into their first language than into their second language, suggesting interpretese is more pronounced in the former direction, and interpreting directions impact interpreters’ language processing. Different classification algorithms vary in terms of their performance in the classification tasks, underscoring the importance of using stacking for ensemble learning to achieve reliable results and justify algorithm selection.
