Word embeddings are an essential instrument in many NLP tasks. Most available resources are trained on general language from Web corpora or Wikipedia dumps. However, word embeddings for domain-specific language are rare, in particular for the social science domain. Therefore, in this work, we describe the creation and evaluation of word embedding models based on 37,604 open-access social science research papers. In the evaluation, we compare domain-specific and general language models for (i) language coverage, (ii) diversity, and (iii) semantic relationships. We found that the created domain-specific model, even with a relatively small vocabulary size, covers a large part of social science concepts, their neighborhoods are diverse in comparison to more general models. Across all relation types, we found a more extensive coverage of semantic relationships.

本文介绍了基于37,604篇开放获取的社会科学研究论文构建和评估词向量模型。在评估中，我们比较了特定领域和通用语言模型在语言覆盖、多样性和语义关系方面的差异。我们发现，即使词汇表的大小相对较小，所创建的特定领域模型覆盖了社会科学概念的大部分，与更通用的模型相比，邻域更加多样化。在所有关系类型中，我们发现更广泛的语义关系覆盖范围。
