摘要:

我们展示了一种新的方法工具,神经网络词嵌入模型,用于大规模文本分析的实用性,揭示了这些模型如何产生更丰富的见解文化协会和类别比可能与以前的方法。词嵌入将词之间的语义关系表示为高维空间中向量之间的几何关系,使符合当代身份和文化理论的意义关系模型可操作化。我们发现,在这些向量空间中,由词的差异(例如,男人-女人,富人-穷人,黑人-白人,自由-保守)引起的维度与文化意义的维度密切对应,并且与调查响应和标记的历史数据相比,词在这些维度上的投影反映了广泛共享的文化内涵。我们试点的方法来测试这些协会的稳定性,然后展示应用词嵌入的宏观文化调查与纵向分析的共同演变的性别和阶级协会在美国在20世纪和历史的区别之间的比较分析标记的性别和阶级在美国和英国。我们认为,这些高维模型的成功激励走向“高维理论化”的意义,身份和文化过程。

英文摘要:

We demonstrate the utility of a new methodological tool, neural-network word embedding models, for large-scale text analysis, revealing how these models produce richer insights into cultural associations and categories than possible with prior methods. Word embeddings represent semantic relations between words as geometric relationships between vectors in a high-dimensional space, operationalizing a relational model of meaning consistent with contemporary theories of identity and culture. We show that dimensions induced by word differences (e.g. man - woman, rich - poor, black - white, liberal - conservative) in these vector spaces closely correspond to dimensions of cultural meaning, and the projection of words onto these dimensions reflects widely shared cultural connotations when compared to surveyed responses and labeled historical data. We pilot a method for testing the stability of these associations, then demonstrate applications of word embeddings for macro-cultural investigation with a longitudinal analysis of the coevolution of gender and class associations in the United States over the 20th century and a comparative analysis of historic distinctions between markers of gender and class in the U.S. and Britain. We argue that the success of these high-dimensional models motivates a move towards "high-dimensional theorizing" of meanings, identities and cultural processes.
