如何从Newsmap（Quanteda）中导出构造好的字典

Question

我已经在 Newsmap 包中为 R 中的 quanteda 训练了一个 newsmap 模型，并试图导出它根据我的语料库（不是种子词典）构建的大型词典。我已经尝试过这段代码，但它只以列表格式为我提供了每个国家/地区 10 个最相关的术语，我也无法提取这些术语以形成我可以在 R 中使用的字典对象。

Dict <-coef(model)

非常感谢任何帮助！

Answer 1

您只需要提取传递给 n.

所需字数的向量的名称

> quanteda::dictionary(lapply(coef(model, n = 1000), FUN = names))
