摘要

我们评估pyConTextNLP包中定义的词汇项在放射学、历史和物理以及急诊科文本中出现的相对频率。虽然我们发现文本类型之间的词汇频率存在显著差异，但近一半的词汇项目在任何文本中都没有发现，这表明可以尝试对词汇知识库进行重大修剪。然而，由于研究的文本数量较少，研究受到了限制。

The Frequency of ConText Lexical Items in Diverse Medical Texts

We assess the relative frequency that lexical items defined in the pyConTextNLP package occur within radiology, history and physical, and emergency department texts. While we found significant disparity in term frequency between the text types nearly half of the lexical items were not found in any of the texts indicating that significant pruning of the lexical knowledge base could be attempted. However, the study is limited by the small number of texts studied.
