Learning a new language is a major challenge faced by many forced migrants. Current vocabulary learning curricula are not adapted to the migrants’ needs, which makes the learning process even more challenging. Today, the widespread use of smartphones among forced migrants provides us with new opportunities to collect and recommend the vocabulary they need. In this work, we propose a demographic- and content-based vocabulary recommendation approach that considers the migrant’s status, migration stage, and vocabulary themes. Based on our approach, the vocabulary recommended to a forced migrant belongs to the same theme as the vocabulary that other forced migrants in the same migration stage chose to learn. The approach was evaluated with 37 Syrian refugees in Lebanon and Germany that used SCROLL, an informal language learning tool, to learn their target language. We compared the learning achievement and motivation of the participants when they learned the recommended vocabulary and the standard textbook vocabulary. Our results showed that the proposed vocabulary recommendation approach resulted in higher learning achievement for refugees in Germany and higher motivation levels for refugees in Germany and Lebanon. Tailored vocabulary recommendation approaches showed potential to improve the language learning experience of forced migrants and warrant further study.

学习一种新的语言是许多强迫移民面临的主要挑战。当前的词汇学习课程无法适应移民的需求，这使得学习过程更具挑战性。今天，智能手机在被迫移民中的广泛使用为我们提供了收集和推荐他们所需词汇的新机会。在这项工作中，我们提出了一种基于人口和内容的词汇推荐方法，该方法考虑了移民的身份，移民阶段和词汇主题。根据我们的方法，推荐给强迫移民的词汇与其他处于相同移民阶段的强迫移民选择学习的词汇属于同一主题。在黎巴嫩和德国的37名叙利亚难民中，使用非正式语言学习工具SCROLL对这种方法进行了评估，学习他们的目标语言。我们比较了参与者学习推荐词汇和标准教科书词汇时的学习成就和动机。我们的结果表明，提出的词汇推荐方法为德国的难民带来了更高的学习成就，并为德国和黎巴嫩的难民带来了更高的动机。量身定制的词汇推荐方法具有改善强迫移民的语言学习经验并值得进一步研究的潜力。我们的结果表明，提出的词汇推荐方法为德国的难民带来了更高的学习成就，并为德国和黎巴嫩的难民带来了更高的动机。量身定制的词汇推荐方法显示了改善强迫移民的语言学习经验并值得进一步研究的潜力。我们的结果表明，提出的词汇推荐方法为德国的难民带来了更高的学习成就，并为德国和黎巴嫩的难民带来了更高的动机。量身定制的词汇推荐方法显示了改善强迫移民的语言学习经验并值得进一步研究的潜力。
