Clustering newsgroups dataset
You should now be very familiar with k-means clustering. Next, let’s see what we are able to mine from the newsgroups dataset using this algorithm. We will use all the data from four categories, 'alt.atheism'
, 'talk.religion.misc'
, 'comp.graphics'
, and 'sci.space'
, as an example. We will then use ChatGPT to describe the generated newsgroup clusters. ChatGPT can generate natural language descriptions of the clusters formed by k-means clustering. This can help in understanding the characteristics and themes of each cluster.
Clustering newsgroups data using k-means
We first load the data from those newsgroups and preprocess it as we did in Chapter 7, Mining the 20 Newsgroups Dataset with Text Analysis Techniques:
>>> from sklearn.datasets import fetch_20newsgroups
>>> categories = [
... 'alt.atheism',
... 'talk.religion.misc',
... 'comp.graphics...
