computeidf func issue
when i run the code the result was 0 for all words
first issue is idfDict = dict.fromkeys(docList[0].keys(), 0)
i changed it to idfDict = dict.fromkeys(list(wordDict.keys())[0], 0)
OR idfDict = dict.fromkeys(wordDict.keys()), 0)
_second the problem comes from the computeidf func
AttributeError Traceback (most recent call last)
in
4 idfDict = dict.fromkeys(list(wordDict.keys())[0], 0)
5 for doc in wordDict:
----> 6 for word, val in doc.items():
7 if val > 0:
8 idfDict[word] += 1
AttributeError: 'str' object has no attribute 'items'_
str here means the doc
How to calculate overall TFIDF Score of particular sentence.
How to calculate TFIDF Score of overall sentence,I am able to calculate TFIDF score of single words.
What is "bow"? :)
Very easy to follow instructions.
Just a quick question: why do u use bow var name? As someone from outside CS, what does "bow" signify here?
Quick tip: space is default split character in python, so you can just use bowA = docA.split(). While bowA = docA.split(" ") is more precise, it is not easier to read.
