SoAn

Code for applying natural language processing methods on whatsapp conversations

SoAn (Social Analysis) can be used to extract word frequency, word clouds, TF-IDF, sentiment analysis, and more from whatsapp conversations. The main application was initially used to analyze the messages between my wife and me, but I extended so that it can be used for your own messages.

2.b TF-IDF

Using a class-based TF-IDF, I extract the most important words per person and plot them using a horizontal barchart with a mask as image. I created a horizontal bar chart with two bars stacked on top of each other both plotted on a background image. I started with a background image and plotted the actual values on the left and made it fully transparent with a white border to separate the bars. Then, on top of that I plotted which bars so that the right part of the image would get removed.

NOTE: In the notebook, you will see more instructions on how to use your own image.

2.c Emoji

These analysis are based on the Emojis used in each message. Below you can find the following:

  • Unique Emoji per user
  • Commonly used Emoji per user

2.d Sentiment Analysis

The sentiment from each sentence in the messages is extract per user using Vader and visualized as follows:

2.e Sentiment Analysis

For each user, a word cloud will be made based on frequent and important words. Stopwords are removed if you have supplied the language:

2.f Topic Modeling

For each user, the most frequent topics using LDA and NMF are modeled and saved a .txt file:

Me

Topics in nmf model:
Topic #0: ga boodschappen nodig lieverd halen uurtje half
