In statistical analysis and ML, it is hard to interpret text (or in general, unstructured data) because of its nature.

The features encompass different aspects of the text, from sentiment analysis, finding the topic of the document, counting the number of words related to several psycholinguistics categories, etc...

| I am currently using my pipeline for two datasets, one is for the people dealing with suicide ideation thoughts which I have their google search, and the second one consists of Morning and Evening journals for the sleep health project, which tries to find some patterns based on textual features to predict the sleep quality and other labels provided in the dataset. |
