Why this code is not working properly for keyword search?












1














I have read the following code from kaggle exercises. The aim of the code for the function multi_word_search(documents1, keywords1) is to show the string indices in documents1 that contain certain words in keywords1. For example if



documents1 = ['what do you want to do', 'what is your research goal', 'what do you want to accomplish in life']
keywords1 = ['want', 'your']


then the output of the function should be {'want': [0, 2], 'your': [1]} but unfortunately the output that I get after running the code is {'want': [0, 2]}. Where is the problem in the code. Any help in this regard will be much appreciated. Thanks in advance.



def word_search(documents, keyword):
indices=
for i, doc in enumerate(documents):
tokens=doc.split()
normalized=[token.rstrip('.,').lower() for token in tokens]
if keyword.lower() in normalized:
indices.append(i)
return indices
def multi_word_search(documents1, keywords1):
keyword_to_indices={}
for keyword2 in keywords1:
keyword_to_indices[keyword2]=word_search(documents1, keyword2)
return keyword_to_indices
s=['what do you want to do', 'what is your research goal', 'what do you want to accomplish in life']
keywords=['want', 'your']
r=multi_word_search(s,keywords)
print(r)

    I get your expected result, {'want': [0, 2], 'your': [1]}, with the code you posted. In your posted code, keywords contains 'your' - BUT in your explanation of the problem you stated keywords1 contains 'you', which kewords are you using?

Instead of writing such lengthy function, you can use dictionary comprehension to get the same results.



In [12]: d = {i : [n for n, k in enumerate(documents1) if any([i == j for j in k.split()])
...: ] for i in keywords1}

In [13]: d
Out[13]: {'want': [0, 2], 'your': [1]}


Here, I'm running loop over the keywords for dictionary (d) keys and the list is being populated by running another loop to find the index of the list that contains the desired keywords.

  • @wwii Why downvote? I said in the beginning that instead of writing such long code that is prone to error if the op is curious enough he can learn the dictionary comprehension. That's how I'm learning programming. If someone else comes with a better idea, if it seems interesting I'll learn it.

  • It still is not an answer to the question and whether a dictionary comprehension is less prone to error than a regular for loop is an opinion.

  • Given the input, you can reach the output several different ways. I showed one way. Better or not certainly opinion based, but seeing all the different options and choosing the best one is certainly better than one way of doing things.
