Learning from students. On the design and usability of an e-dictionary of mathematical graph theory
(2022)
We created a prototype of an electronic dictionary for the mathematical domain of graph theory. We evaluate our prototype and compare its effectiveness in task-based tests with that of Wikipedia. Our dictionary is based on a corpus; the terms and their definitions were automatically extracted and annotated by experts (cf. Kruse/Heid 2020). The dictionary is bilingual, covering German and English; it gives equivalents, definitions and semantically related terms. For the implementation of the dictionary, we used LexO (Bellandi et al. 2017). The target group of the dictionary are students of mathematics who attend lectures in German and work with English resources. We carried out tests to understand which items the students search for when they work on graph-theoretical tasks. We ran the same test twice, with comparable student groups, either allowing Wikipedia as an information source or our dictionary. The dictionary seems to be especially helpful for students who already have a vague idea of a term because they can use the resource to check if their idea is right.
This paper describes the results of an empirical investigation carried out within the project Lessico Multilingue dei Beni Culturali (LBC), whose aim is to create a multilingual online dictionary of the lexicon of the Italian artistic heritage. The dictionary, whose lexicographic process has already started, is intended for linguists and specialist translators as well as for professionals in the tourism sector and students of Foreign Languages and Literatures. The investigation conducted through a questionnaire submitted to undergraduate students at the University of Milan and at the University of Florence has a double aim: to research the habits in the use of lexicographic tools by possible users of the dictionary (Italian Learners of German Language), and to identify preferences regarding macro-, medio- and microstructural features of the future LBC-dictionary to realize a user-friendly tool. After a brief introduction on the state of the art of the survey in the field of Dictionary Users Studies, the article describes the questionnaire and the results obtained from the pilot study. A summary and a discussion on the future developments of the project conclude the work.
