What have we learned about studying Text Mining?
Lot of new things about how to work with text data.
All of these ideas are as useful as computing means, standard deviation, correlations, t-tests, regression, etc. for numeric data.
You are now prepared to work with the other half of the data that is out there in the world!
We have studied Unsupervised Learning techniques for text based data.
Sentiment Analysis is very useful for learning about the sentiment in documents.
We have studied Unsupervised Learning techniques for clustering text based data.
Topic Analysis is very useful for learning about the different topics discussed in documents.
We have studied Supervised Learning techniques for classifying text based data.
Naive Bayes and Logistic Regression with lasso/regularization are very useful for predicting which class documents are in.
There are a lot of other R packages that can be used for Text Mining.
There are a lot of Python packages that can be used for Text Mining.
There are growing opportunties to work doing Text Mining. This is a very interesting new field to work in and there are a growing number of excellent tools available to pursue such work.
