如何使用正则表达式从python的字符串中提取大学/学校/学院的名称？

Question

SAMPLE CODE

import re
line = "should we use regex more often, University of Pennsylvania. let me know at  321dsasdsa@dasdsa.com.lol"
match = re.search(r'/([A-Z][^\s,.]+[.]?\s[(]?)*(Hospital|University|Institute|Law School|School of|Academy)[^,\d]*(?=,|\d)/', line)
print(match.group(0))

I'm trying to extract University/School/Organization names from given string using regular expression in python but it gives an error message.

ERROR MESSAGE

Traceback (most recent call last): File "C:/Python/addOrganization.py", line 4, in print(match.group(0)) AttributeError: 'NoneType' object has no attribute 'group'

Answer 1

Instead of search ,Try the re.sub to print your expected output

import re
i = "should we use regex more often, University of Pennsylvania. let me know at  321dsasdsa@dasdsa.com.lol"
line = re.sub(r"[\w\W]* ((Hospital|University|Centre|Law School|School|Academy|Department)[\w -]*)[\w\W]*$", r"\1", i)
print line

Answer 2

The test string you've given is a made up one since the University name is immediately followed by a line terminator '.' while the other examples in your pastebin sample do not (they are followed by a comma).

line = should we use regex more often, University of Pennsylvania. let me know at 321dsasdsa@dasdsa.com.lol

I have managed to extract the names using a simple regex for examples in your pastebin you can see details here: regex101.com

Logic

Since the institute name is separated by a comma (except the first case where it starts with the university name), you can see that the match string will either lie in group1 or group2 .

Then you can iterate through group1 & group2 to see if it matches anything in the pre-defined match list & return the value.

Code

I have used two examples to show it works.

line1 = 'The George Washington University, Washington, DC, USA.'
line2 = 'Department of Pathology, University of Oklahoma Health Sciences Center, Oklahoma City, USA. adekunle-adesina@ouhsc.edu'

matchlist = ['Hospital','University','Institute','School','School','Academy'] # define all keywords that you need look up
p = re.compile('^(.*?),\s+(.*?),(.*?)\.')   # regex pattern to match

# We use a list comprehension using 'any' function to check if any of the item in the matchlist can be found in either group1 or group2 of the pattern match results
line1match = [m.group(1) if any(x in m.group(1) for x in matchlist) else m.group(2) for m in re.finditer(p,line1)]
line2match = [m.group(1) if any(x in m.group(1) for x in matchlist) else m.group(2) for m in re.finditer(p,line2)]

print (line1match)
[Out]: ['The George Washington University']

print (line2match)
[Out]: ['University of Oklahoma Health Sciences Center']
