摘要:

词嵌入是许多NLP任务中必不可少的工具。大多数可用的资源都是从网络语料库或维基百科转储的通用语言进行培训的。然而,领域特定语言的词嵌入是罕见的,特别是社会科学领域。因此,在这项工作中,我们描述了基于37,604篇开放获取的社会科学研究论文的词嵌入模型的创建和评估。在评估中,我们比较了特定领域和一般语言模型的(i)语言覆盖率,(ii)多样性和(iii)语义关系。我们发现,创建的特定领域的模型,即使有一个相对较小的词汇量,涵盖了社会科学概念的很大一部分,他们的邻居是不同的,相比更一般的模型。在所有关系类型中,我们发现语义关系的覆盖范围更广。

英文摘要:

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.
