从文本语料库中分离非结构化句子

时间:2017-05-31 04:51:49

标签: python python-2.7 text nltk

我正在开展一个项目,我必须将正确的句子与文本语料库分开。我尝试过使用NLTK句子标记符,但它似乎基于句点("。")来标记句子。

所以我在想是否有办法将表格数据,短语与文本文件分开?

这是一个示例文本文件。我在TEXT标签下引用它们。

A/P: 48M with a hx of DM2, PVD and multiple admissions in the past for LE cellulitis in the setting of gangrene. 

1.  ID: Patient is now presenting with appears to be another episode of cellulitis but now probably coming from his L 5th Toe lesion. Surgery has debrided the wound, sending wound cultures as well as blood cultures. Acute OM would not be visible on XR changes and clinical picture is more consistent with acute than Chronic OM. Will consider further work up for OM if symptoms do not respond to treatment. Levo and flagyl were added to unasyn in accord to previous culture data.

2.  PVD: Will need arterial LENIS to assess for vascular patency and flow. Continuing ACEI, and adding ASA and lipitor, will order lipid profile and smoking cessation consult.

3.  DM2: Very poor control last admission, eventhough patient now says he takes medications and checks it up to QID. Will order HgbA1C and glucose monitoring.

每当我尝试在句子基础上对上面的文本进行标记时,NLTK就会混淆并将一段时间(&#34;。&#34;)作为一个句子整理出来。

1 个答案:

答案 0 :(得分:0)

此文件中的某些行(实际段落)包含多个句子。将文件拆分为行,然后将句子标记生成器分别应用于每一行。这将阻止合并来自不同行的文本,并且比滚动自己的基于正则表达式的句子分割器提供更好的结果。例如:

text = file.read()
lines = text.splitlines()
sentences = [ s for line in lines for s in nltk.sent_tokenize(line) ]
