Different ways to express personal attitudes in Spanish and English engineering papers: An analysis of metadiscourse devices, affective evaluation and sentiment analysis

[EN] The hypothesis of this paper is that writers with similar academic backgrounds express personal attitudes in English and in Spanish differently in research papers. Thus, the main objectives are, first, to study the differences in the use of attitude devices in Spanish and English academic discourse; second, to compare the results in the different sections of articles; and finally to study the positive or negative semantic implications of the lexical items by carrying out a sentiment analysis. To this end, fifteen Spanish industrial engineering papers were compared with fifteen English industrial engineering papers. The results showed that there are in fact differences in the way academic writers communicate attitude, but the sentiment analysis revealed that neutral lexical items were the most commonly used in engineering research papers. Even though engineering researchers share the knowledge of the specialist content and the academic style of expressing their thoughts, personal attitudes were expressed in different ways in Spanish and in English.
