Join Barton Poulson for an in-depth discussion in this video Text mining goals, part of Data Science Foundations: Data Mining.
- [Narrator] Text Mining is one of the most important forms…of Data Mining that you could use…and what makes it really different is that…this time, we're using Unstructured data.…It's not numerical data that's in rows…and columns or in lists,…it's just a blob of text,…and there are a few different reasons…you might wanna do this.…Now as a researcher,…one of my favorite is Assessing Authorship in documents,…seeing who wrote it…or seeing for changes in voice over time.…Another one is Clustering Groups of Respondents.…Clustering's a very big topic…in a huge number of fields…and using natural text can be a great way…of getting more insight into clusters.…
Finally, another very common use…is Sentiment Analysis in Social Media…and in news articles…and in blog posts…and telling whether people are basically saying…positive or negative things about something.…Without having to read through all of it,…you can get some of this…very basic information with Text Mining.…Now let me say a little more…about each of these.…First one is Comparing Voices.…
