Amazing Word clouds using python

Ever wondered how word clouds are generated from a big text corpus? In this post we learn how to make interesting word clouds using simple natural language processing and python.

What are word clouds?
Word clouds are a way of representing some of the most important words or some of the most occurring words from the big text corpus.

In this post we will consider the some speeches by George Bush as our test corpus and make a word cloud from the words that occur the most in the speeches.

Steps taken

  1. Load the speeches and store them in a variable
  2. Remove all the stopwords, stop words are words like 'the', 'and', 'this' and they can be removed for our current purpose.
  3. Remove all the punctuation's
  4. Construct word cloud consisting of 100 most frequent words and save the image

Lets have a look at the code

The above code produces the following image as the output



Now, the above code produces a simple image, we can mask and try to make our word cloud more interesting by using the following code.

The output produced by the above code is



The mask used for the above code was downloaded from

Hashing with Linear Probing

Hashing is a technique used for storing , searching and removing elements in almost constant time. Hashing is done with help of a hash function that generates index for a given input, then this index can be used to search the elements, store an element, or remove that element from that index. A hash function is a function that is used to map the data elements to their position in the data structure used. For example if we use an array to store the integer elements then the hash function will generate position for each element so that searching, storing and removing operation on the array can be done in constant time that is independent of the number of elements in the array. For better look at the example below. now we face a problem if for 2 numbers same position is generated example consider elements 1 and 14 1 % 13 = 1 14 % 13 = 1 so when we get 1 we store it at the first position, but when we get 14 we see that the position 1 is already taken, this is a case of colli

Infix to Prefix conversion using Stack

This post is about conversion of Infix expression to Prefix conversion. For this conversion we take help of stack data structure, we need to push and pop the operators in and out of the stack. Infix expressions are the expressions that we normally use, eg. 5+6-7; a+b*c etc. Prefix expressions are the expressions in which the 2 operands are preceded by the operator eg. -+56 7 , +a*bc etc. This method is very similar to the method that we used to convert Infix to Postfix but the only difference is that here we need to reverse the input string before conversion and then reverse the final output string before displaying it. NOTE: This changes one thing that is instead of encountering the opening bracket we now first encounter the closing bracket and we make changes accordingly in our code. So, to convert an infix expression to a prefix expression we follow the below steps (we have 2 string, 1st is the input infix expression string 2nd is the output string which is empty initially)
