This was an interactive webinar aimed at all academics and practitioners from the fields of Sociology, Communication Sciences, Lexicology, Linguistics and Translation Studies, who are interested in international comparable surveys, survey research and methods, and translation of questionnaires. Participants have gained practical insights into the creation of Multilingual Corpus of Survey Questionnaires. The Multilingual Corpus of Survey Questionnaires (MCSQ) is the first publicly available corpus of international survey questionnaires, comprising survey items from the European Social Survey (ESS), European Values Study (EVS), and the Survey of Health Ageing and Retirement in Europe (SHARE). The recently released Version 2.0 (entitled Mileva Marić-Einstein) is composed of questionnaires of the aforementioned studies in the (British) English source language and their translations into eight languages, namely Catalan, Czech, French, German, Norwegian, Portuguese, Spanish, and Russian, as well as 29 language varieties (e.g. Swiss-French). The MCSQ is a relevant digital artefact, that allows researchers in the fields of social sciences and linguistics to quickly search and compare survey items in a myriad of languages. In this seminar, we present the corpus characteristics and showcase applications of the MCSQ. This webinar had two parts: 40 minutes presentation and 20 minutes Q&A session.
